Many homeowners are concerned today about garage ventilation. This is because it can be dangerous when your garage is not ventilated properly. There are a number of toxic fumes that invade your garage such as your car’s exhaust fumes. When you don’t have proper ventilation of these fumes, they can become trapped inside your garage walls and get into your home, which can cause a health hazard.

There is also heat build-up in your garage, which is another reason it’s important to get proper air circulation in it. Since your garage doesn’t have a whole lot of air space, it can get really stuffy. Thankfully, there are ways you can improve the air circulation in your garage to safeguard your health and help you feel more comfortable while spending time in your garage.

Windows and Doors
Although you don’t want to keep your doors and windows open all the time (for safety reasons), you can open them up while you are home to improve airflow. If you don’t have windows in your garage, you can have them installed by a carpenter or window installation company.

To get the best airflow, open up windows vertical to your garage door on opposite sides. You can still maintain your privacy and security by having window locks installed or having the glass of your windows frosted so nobody can see in your garage.

If your garage doesn’t already have rooftop vents, you might want to consider installing some. Box vents, turbine vents and gable vents help to improve air flow but don’t pose the risk of animals or people getting into your garage.

Install a Garage Exhaust Fan
There is probably a good chance you spend some time in your garage working. If you do, investing in a garage exhaust fan might be well worth the investment. Garage exhaust fans will help keep your work area cool while spending time in your garage.

Importantly, garage exhaust fans will also exhaust out the fumes of insecticides, paints, primers, parked cars and other things you have inside your garage that you store. These fumes can get overwhelming and are not good for you. These fans help draw fumes like these outside your garage.

Also, although these fans might not prevent all the heat from getting into your garage, they can certainly make your garage more comfortable. They also help to vent moisture out of your garage which can lead to mildew and mold causing your expensive tools to rust and not something you want to breathe in.

Air circulation is very important in your garage and shouldn’t be overlooked. You can properly ventilate your garage, cool it off and get rid of toxic fumes simply by installing a garage exhaust fan.

For many people, the attic is an area where they store old family photos, clothes, holiday decorations, and luggage. However, for energy researchers, it’s much more than that. In fact, over the past 30 years, building codes have been put in place requiring more attic insulation.

And, most professionals will tell you that when your attic is well-ventilated, your house stays much more comfortable during the summer months and stays protected from moisture buildup during the winter from heated air. Not to mention, proper attic ventilation (and roof ventilation) extends the life of your roof’s shingles, prevents ice dams and roof rot, and reduces your cooling bill. Below are other reasons why your home needs more attic ventilation.

Removing Moisture
As the temperature outside drops, we fill our homes up with added heat and moisture. You may notice this “added moisture” by taking a look at the condensation that builds up on your windows. Colder air during the winter comes into your home through your basement and rises to your attic. And, just as moisture is drawn to your windows, it’s also drawn to cold surfaces in your attic, which can cause mold and rot. Attic ventilation helps this moisture escape your attic before it can cause mildew, mold, rot and other issues.

Prevents Ice Dams and Keeps Attic Cool
You might think it’s silly to install extra insulation to keep your attic warm and then turn around and allow colder air to come through the vents of your attic.  However, this combination is what makes your home energy-efficient and durable. This is because during the wintertime, when you keep your attic a little cooler by letting in outdoor air, it reduces the risk of ice dams forming, which happens when your attic is too warm and causes snow to melt off your roof and then refreeze at your gutters.

With proper air sealing and insulation, you can keep your attic cold in the wintertime and block out the moist, heated air from below. The natural flow of air in the summertime in your attic that is well-ventilated moves the extreme heat out of your attic which removes moisture and protects your roof shingles.

A great way to ventilate your attic properly is by installing an attic fan. This type of fan will cool down your hot attic since it draws in the outdoor cooler air from the vents in your attic and pushes out the hotter air to the outdoors. Just keep in mind that if your soffit vents in your attic are blocked and you don’t seal off your attic properly from your home, the attic fan can actually suck up your cooler air conditioned air from your home into the attic making your AC unit work harder and increasing your utility bill. Therefore, be sure you properly seal up your attic and ensure soffit vents are not blocked before you run your attic fan for the best possible results.

Many homeowners overlook the attic since it is tucked away, they don’t think about it. However, a large chunk of your monthly energy bill can come from your attic and your roof vents without you even knowing if your home has poor attic ventilation.

Poor attic and roof ventilation can cause damage to your roof too. For each 300 sq. feet of space in your attic, you should have a minimum of one sq. foot of ventilation, according to the Federal Housing Administration. And to avoid clumping insulation, mold and rotting wood, you need to properly ventilate your attic. Here’s how.

Monitor the Temperature
Your venting system’s circulating air is needed not just to control moisture, but it regulates temperature as well, which is especially important in the summer months. When there isn’t sufficient circulation coming from your vents, your attic’s temperature can reach to over 140 degrees Fahrenheit on summer days, which can affect your living space climate significantly.

You should keep an eye on attic temperature regularly with a thermometer in the summertime. If you notice the temperature getting hot, you will likely have to add in some power vents to improve your passive ventilation system.

Add Vented Soffits
Although there are a number of reasons why you could have blocked soffits, what happens afterward is always the same. When air isn’t entering a soffit and escaping through the vents of your roof properly and heat that begins radiating into your insulation gets trapped, it results in ice damming which can lead to water damage. To properly fix an ice damming problem, you need to change your soffits.

Install an Attic Fan
You can use attic fans to increase attic ventilation. These help to provide proper ventilation and can save you on energy costs. Good ventilation can also extend the service life of a number of important components like insulation, trusses and roof framing, electrical wiring, venting, plumbing and others that you will find in the attic space of your home. Without an attic fan, the temperatures of your attic can rise significantly. Attic fans help cool down your attic and create a steady flow of air throughout your attic space.

When you are trying to be energy efficient, proper ventilation is needed. You also need it to regulate attic space temperature and preserve the health of your roof.  Following the tips above can help you with ensuring you have good attic ventilation.

Icicles can be beautiful, but if left hanging, they can loosen shingles, tear off your gutters, and cause a backup of water into your home. That sure doesn’t sound pretty, right?  Even though they are a given in snowy areas, you can reduce them or even eliminate them altogether.

How Ice Dams Form
Ice dams form along the edge of your roof. Their formation prevents the melted snow from properly draining off your roof. The water back-up they cause can damage your ceilings, walls, insulation and other parts of your home.

Ice dams form when you have warm air in your attic and a warm roof, which causes snow on the roof to melt after a heavy snowfall. The resulting water runs down your roof and once it gets to the colder roof edge it refreezes and forms a mound of ice.

This ice mound traps the melted water and causes it to seep up back under your shingles, dripping through your roof into your home. This is when the damage happens.

Below are some tips to reduce and eliminate ice dams.

Tips to Reduce or Eliminate Ice Dams
Here are some easy tips to get rid of your ice dam problem.

Attach Heating Cables
Attach heating cables along the edge of your roof with clips in a zigzag pattern. This will allow you to heat up your roof from the outside to equalize its temperature rather than blowing in colder air from indoors. Be sure you have the heating cables installed before the snowy weather hits.

Rake it
Use a long-handled roof rake to pull the snow off. You can use a rake that has wheels to change your roof’s exterior temperature instantly without causing any damage to your shingles.

Check the Insulation in your Attic
Investigate the depth of the insulation in your attic. Standard building codes call for around 12 to 14 inches of cellulose or fiberglass insulation. If you have had problems in the past with ice dams or you have less than eight inches of insulation, add more. It’s best to hire a professional to come do this job.

Panty Hose
A pair of panty hose works great for diminishing the damage that ice dams leave behind. Add some calcium chloride ice melter to a pair of panty hose and lay them on your roof having them hang over your gutters and cross over the ice dams.

You can eliminate ice dams for good. All you need to do is keep your roof and eaves the same temperature. This can be done by adding insulation, increasing ventilation through an attic fan, and sealing off any potential air leak that could possibly warm the underside of your roof. Easy fixes like these can help you remove trouble areas and enjoy a winter free of ice dams.

Check out our selection of attic fans here at, so you never have to deal with the damage left behind by an ice dam.

Icicles might be pretty to look at, but they can potentially damage your home or business. And, when you have icicles, you are sure to have ice dams. These are a fairly serious problem too. You might not even know you have them. If you notice a layer of thick, solid ice building up along your roof’s edge when you look outdoors, this could mean trouble for you.

The freezing temperatures outdoors, warm temperatures indoors, and piles of snow on your roof is the perfect recipe for ice dams and icicles. Warmer air rises up into your attic melting the snow that piles up on your roof. However, the snow on the eaves is not melted which causes the snow melt from your roof to freeze up on your eaves and build up ice. And since there is no place for it to go, the water begins backing up behind the dam.

This ‘building up’ and ‘backing up’ of water can cause serious trouble. Roof experts claim that your roof shingles can become loose from the dams and result in water leaking into your home. Here’s what you can do:

Attic Bypasses Need to be Closed up
A significant amount of heat loss can come from your attic ceiling. This is typically due to air leaks coming from gaps in your drywall, unblocked walls, plumbing pipes, light fixture cracks, ceiling penetrations and access hatches. Be sure you close up all bypasses in your attic to stop air leaks.

Add Insulation
Keep your heat inside your home by adding more insulation. You can consult with your city’s building department to determine how much attic insulation to install.

Caulk Penetrations
Seal around vent pipes and electrical cables using a fire-stop sealant. Check to see if any of your insulation is black from dirt left behind from passing air or if you see any areas where light is shining through.

Ventilate Ridge and Eaves
Circulate cold air underneath your roof with continuous soffit vents and a ridge vent. Both soffit and ridge vents need to have equal size openings and for every 300 sq. ft. of attic floor, have a minimum of one sq. ft. of opening. Maintain a clear airflow path from the soffit vents by placing baffles at the eaves.

Bottom line, if you are having trouble with icicles and snow dams and want to prevent serious issues, plumbing and roofing companies say that it’s important to get gutter and roof inspections every spring and fall. They will also be happy to come over and clear away your ice and snow.

You should also be sure that you have proper attic ventilation through the use of an attic fan.

Cleaning your air ducts is an important process of clearing the air in your home. The EPA says that indoor air quality inside buildings today is often two to five times worse than the air quality outside – and can be much worse than that.

If you’re like most people, you think of your home as a safe haven from the harmful things in the world. Unfortunately, no matter how hard you try to keep the surfaces and floors in your home clean, the air you breathe could be causing harm to your family – unless you clean your air ducts.

Why is it Important to Clean Your Air Ducts?
Whether you have a heater, air conditioning or a whole house fan that runs through your air ducts, you need to have your ducts cleaned at least once a year. Those ducts are used constantly to transport air throughout your home.

The National Air Duct Cleaners Association reports that the ducts in your HVAC system recirculate the air inside your home between five and seven times per day, which can lead to a buildup of contaminants within the ducts. Below are a few other great reasons to clean your air ducts.

To Prevent Mold and Mildew
Moisture is a big problem in homes today. While a whole house fan is a great tool for improving ventilation in your home and helping to avoid mold and moisture buildup within the home, the ducts themselves can be a hidden location where mold can build up and hide from view. Having them cleaned by professionals can help to remove the hidden moisture.

You may also elect to use biocides to prevent certain bacteria and molds from growing in your ducts in the future – however, the EPA is skeptical as to whether or not biocides are effective in this application, so consider carefully whether that’s a move you really want to make.

To Clear Out Debris
This is especially true for families who have vents and air ducts in floors – and children. You’ll be amazed at all the tiny things that fall into the air ducts through the floor vents. Legos, Barbie Doll shoes, Polly Pockets, hair ties, paper clips, rubber bands… the list goes on.

All of these small things can get recirculated through your air ducts forcing your heater, whole house fan, or air conditioner to work even harder to move the nice warm or cool air to the places you want it to be. Routinely clearing out the debris allows your equipment to operate more efficiently.

Of course, the most important reason to clean out your air ducts is for the good health of your family. Allergens and irritants can be trapped inside and circulated throughout your home if you aren’t careful. Cleaning out the ducts means you don’t have to worry about allergies, asthma attacks, and other upper respiratory problems that could occur if your fail to do so.

Having the air ducts in your home or business cleaned is a measure to help you to have better indoor air quality.  In addition, a whole house fan will improve the ventilation inside your home.

Although when you think of buying an attic fan, it’s something that you may generally equate with needing in the summer months, it’s important to note that these pieces of equipment are just as important in the cold, winter months, if not even more so.

In the summer, you’ll need an attic fan to disperse hot air so it doesn’t accumulate and overheat your home. In winter, due to the accumulation of moisture as a result of huge variations in temperature, you could find that this is just as damaging to your property as the summer heat. The winter months can spell conditions such as wood rot, insulation damage, fungus and mold growth, as well as leaks coming into your home.

Thankfully, an attic fan is designed to both reduce summer heat, as well as reducing winter moisture issues. Let’s take a look at the dangers of moisture build up in your home, as well as how an attic fan can help prevent problems from arising.

Prevent Ice Dam Damage
In addition to the concerns already mentioned, if you live in a cold and snowy climate, ice dams are a common concern. These are created when hot air rises into the peak of your attic. Snow on the roof will then melt, and the water then flows downward towards the gutter and eaves, and consequently refreezes.

Over days, this can accumulate into a sizeable ice pile, subsequently creating a blockage that will prevent water from draining. As a result, water will get under the shingles, and can cause damage to your roof, ceilings, insulation, and walls.

Prevent Condensation
Throughout the winter months, heated indoors air collects the water vapor that’s created from washing dishes, cooking, doing laundry, and bathing. This moist air will then travel into your drier, and colder attic.

Even if your home has a vapor barrier, this air can get through any openings around your light fixtures, as well as attic entrances and bathroom exhaust fans into the top of your home’s structure.

This warm, moist air will eventually collect as frost or water droplets, and condensation will in time drip down onto the insulation below, rendering it far less effective. Due to this, loss of heat increases, the temperature decreases, and your entire living space will get colder, resulting in the need to increase your heating, which will make your energy bills higher.

An attic fan will equalize indoor and outdoor temperatures, preventing condensation build up. Buying one is also far more affordable than paying out for high home repair bills from doing nothing to protect your home in the winter.

Each year causes more havoc on your roof. Rain, wind, sun, ice and snow can all shed years off your roof’s lifespan since they can cause premature aging. Whether your roof is old or brand-new, there are things you can do to extend its life and keep it in good shape as long as possible.

Make Regular Roof Inspections
If you have skylights, inspect them and repair them if needed. Check your chimney’s flashing to ensure it’s not deteriorating. Check your vents to make sure they are working properly and aren’t blocked. Inspect your attic ceilings and your roof for signs of interior or exterior damage, wear, mold, structural problems, leaks or rot. Be sure to repair these kinds of things immediately since when you don’t repair them right away, it can lead to costly fixes over time.

Inspect your Gutter
Your gutters can be easy to overlook, but are very important to inspect, particularly during the rainy season. Leaves and other debris can clog up gutters and weigh them down to the point where they pull apart from your home completely.  If you don’t keep an eye on your gutters, it can result in costly expenses later on. Twice a month is adequate for checking your gutters.

Use Roof Coating
You can find environmentally-friendly and economical roof coating to protect your roof against weathering. If you have asphalt shingles, you should try RoofKeeper and if you have sheet-metal roofing, RoofSkin. Both are applied to your roof like you would paint. They are meant to protect your roof from strong winds and severe climate. The coating stays flexible, is ultra-adherent and lasts for up to 10 years.

Ensure Proper Attic Ventilation
Proper attic ventilation is imperative to the life of your roof. You need to remove any dirt, dust or debris that can block proper attic ventilation. Proper attic ventilation will help prevent ice damming which can damage your roof. Ice damming is where water forms and freezes from melting snow along your roofline edge. If left untouched, the ice can grow big enough preventing water from melting snow to drain off your roof properly. A good way to ensure you have proper attic ventilation is by installing an attic fan.

Don’t skimp out on hiring professionals to come help you extend the life of your roof. Your home is a huge investment and your roof is a big part of it. You want it to last as long as possible to help save you thousands of dollars. It’s a good idea to have a professional come in and inspect your roof at least once a year.

The EPA reports that indoor air quality is typically two to five times worse than air quality outdoors and can be up to 1000 times worse. Considering that the average person spends as much as 90 percent of your time indoors, it is important to take action to clear the air in your primary environment. One way you can do that is by cleaning your air ducts.

Air Duct Cleaning Basics
When you have your air ducts cleaned, someone comes into the home and cleans the ducts where air travels throughout your home. This can be the ducts that are used for heating your home, air conditioning, and even for your whole house fan. It isn’t only the ducts that are cleaned, though, but the heating and cooling coils and drain pans are cleaned at this time too. The EPA also recommends changing your filters routinely throughout the year to keep them free of potential toxins.

During the course of a year, these ducts fill with dust, debris, pollen, mold, and even bacteria that is transported from one area of your home to another through the ducts. This can lead to upper respiratory problems, allergy problems, and even asthma attacks for your family.

Some services that offer air duct cleaning will suggest applying chemical biocides to the air ducts. While they can be highly beneficial for preventing mold and certain bacteria from growing in your air ducts in the future, the EPA has not cleared any biocides for use in air ducts that are lined with fiberglass or made with fiberglass duct board. So, make sure this isn’t an issue with your duct system before agreeing to let your service provider apply chemical biocides.

Who Needs to Have Air Their Ducts Cleaned?
You might be surprised to learn that air duct cleaning is a great investment for the health of families in every household. You should especially consider the benefits of having your ducts cleaned, though, according to the National Air Duct Cleaners Association, if you own pets, smoke cigarettes or cigars, have experienced water damage to your home or HVAC system, have gone through a recent home renovation, or if someone in your household suffers from asthma or allergies.

While the health benefits alone are enough to encourage you to have your ducts cleaned routinely, the energy savings benefits are icing on the cake. When your ducts are filled with contaminants, it makes your heating and cooling units operate less efficiently. This is part of the reason why between 25 and 40 percent of the energy used to heat and cool your home is wasted energy.

Getting your air ducts cleaned at least once a year is a great way to help have better air quality inside your home. In addition, consider a whole house fan to improve the ventilation inside your home.

When you’re involved in household projects like painting and decorating, or laying down new carpets, you can’t avoid releasing chemicals from these activities into your indoor air. You might not have known it, but there are actually some houseplants that double up as very efficient air purifiers.

In 1998, the National Aeronautics and Space Administration (NASA) found that certain house plants can absorb toxin in the air.

For best results, place a few of the following plants in the rooms you use most, in ones you are decorating, or in which you’re using chemical-treated products. NASA also recommends that for every 100 square feet of living space, you place two to three plants in 8 to 10 inch pots.

Although there are others, let’s take a look at five of the most popular and efficient plants for purifying the air in your home.

1) Peace Lily
The Peace Lily, (Spathiphyllum), is one of the very few air purifying plants that flower.This extraordinary plant is believed to extract VOC benzene from the air. This is a carcinogen that’s found in polishes, furniture waxes, and paints. The plant also rids the air of the acetone that’s emitted by adhesives, some cleaners, and electronics.

If you have pets in your home, however, it may not be the best choice as it’s poisonous to animals.

2) English Ivy
English Ivy, (Hedera helix), is a climbing vine that does very well in rooms with little sunlight, so it can be placed in any room in any home.

This little plant is thought to absorb formaldehyde which is the most common indoor air pollutant, and can be found in synthetic carpet dyes, and wood floorboard resins.

3) Lady Palm
The Lady Palm, (Rhapis excelsa), is slow-growing, tree like, and easily cultivated. This pretty plant is thought to clean the air of the ammonia contained in dyes, textiles, and cleaners.

4) Snake Plant
The Snake Plant, (Sansevieria trifasciata), also known as mother-in-law’s tongue, is a spiky sharp-leafed plant that does well in low light.

Placing a plant or two in your bedroom will give you a tiny oxygen boost when you sleep, as the plant absorbs CO2 and releases oxygen. The plant also extracts benzene and formaldehyde from the air.

5) Wax Begonia
The Wax Begonia, (Begonia semperflorens), thrives in very sunny areas of your home, and produces attractive clusters of red, white, or pink flowers during the summer months.

This plant is believed to be excellent at filtering out benzene, other chemicals, produced by toluene, a liquid within some adhesives and waxes.

For purer air in your home, nothing can beat the natural air-cleaning attributes of these amazing plants. When you use them in conjunction with a whole house fan to help improve your ventilation, their effects can be even further intensified.


In the push for energy efficiency in modern homes, builders have taken to building homes that are extremely tight. While it is great for keeping cold air in during the dog days of summer and cold air out when winter’s winds are blowing hard, there are definite downsides to it that you need to know about it.

Indoor Air Quality
The biggest downside for of having a home that is too tight is the fact that over time the indoor air quality begins to suffer – tremendously. It doesn’t take that long either. Everything in the home from building materials to cooking food, and even what people bring into the home on the soles of their shoes has the potential to contaminate the air every day. When these things come into or are introduced into a “tight” home, they have no way to escape and this can lead to poor air quality inside your home.

No Escape for Moisture, Mold, and Mildew
The same concept holds true when it comes to moisture. Moisture is created inside the home and carried throughout the home whenever you prepare meals, take baths, or wash clothes and dishes. Rainy and snowy days bring moisture in on boots and clothes. If you have pets, it’s a never-ending battle to keep moisture from becoming a big problem throughout your home.

What Can You Do to Help?
While you may be saving a great deal of money on your monthly energy bills, that savings could come at a great cost to personal health and the structure of your home. It may appear to be hopeless if you’re going to have to choose between a home that is energy efficient or one allows bad air to escape while bringing fresh, clean air in.

The good news is that there several options that will allow you to have the best of both worlds. You get to enjoy the energy savings of a tight home and clean air to breathe when you install and use a whole house fan into your home. Combined with open windows and proper ventilation, these fans draw heat, moisture, allergens, toxins, and more out of your home leaving breathable air behind instead.

In addition to a whole house fan, or instead of, in areas where opening lower floor windows isn’t practical, consider installing garage exhaust fans to cool your garage by several degrees during the summer while clearing the air. In addition, an attic fan can extend the life of your roof if moisture sits in your attic and turns to ice or frost in the winter.

Little moves let you enjoy real energy savings without increasing risks to your health or your home in the process.

A whole house fan offers many potential benefits to homeowners. These include lower utility bills, cooler homes, better air circulation throughout the home, and the satisfaction of reducing your carbon footprint. Not bad for a day’s work, right?

But, it only offers these benefits if you choose the right whole house fan for your home and your needs. Getting the wrong whole house fan may save you now, but cost you later, or it may be inefficient for the needs of your home. These are a few things to consider so that you choose the best whole house fan for your home.

Cooling Efficiency
Getting the right size fan is very important if your goal is to cool your home in a cost effective manner. Ideally, you want to purchase a whole house fan that will move 1.5 to 2.0 CFM per square foot of living area in your home. For example, if you live in a 2,000 square foot home, you will want to purchase a fan with a rating of 3,000 – 4,000 CFM.

Breeze Generation
Some homeowners want more than a gentle cooling. They want to feel a definitive breeze wafting through the home. Cooling will occur more rapidly with this choice, though it may lack the energy efficiency of other fan choices. In this instance you are looking for 2.5 to 3.0 CFM per square foot, which would require a whole house fan offering 5,000 to 6,000 CFM for a 2,000 square foot home.

Adequate and Appropriate Roof Venting
The most important aspect of any whole house fan is the proper balance of cool air coming in and warm air going out. The air going out must have proper ventilation, through roof vents, so that the air can escape as rapidly as it is coming in. To determine this you must take the CFM of airflow specific to the fan and divide by 750. This tells you how many square feet of free venting you need for that fan.

There are, of course, other important considerations for whole house fans too, such as:

Location of the fan – an open hallway allowing access to various rooms throughout the home is best.

Type of fans – people who experience periodic cold snaps will need insulated-door fans while those in Southern California can use standard fans fine for the most part.

These simple rules will help you choose the right whole house fan for your home and the cooling effect you most desire.
