Dust and debris in a home air filter restrict air flow, which forces your furnace to strain and use more energy to heat or cool your home. Just like replacing your car engine’s oil and air filter every 3,000 miles, a clean HVAC air filter protects your furnace system from becoming damaged and, ultimately, failing entirely. But how can such a simple and relatively inexpensive component have such a big impact on energy consumption, equipment life and air quality? In other words, how can a $15-30 filter protect a $2,500-$3,500 heating and cooling system? To answer this question, we first need to understand how your home is heated and cooled and then how air filter clogs prevent your system from operating efficiently. A forced-air system, which is the most common heating and cooling system, uses a heat exchange to heat or cool incoming air that is then blown through metal/flexible ducts to the various rooms in your home.

As the warmed or cooled air flows into the rooms, the unit’s fan pulls existing air out of the rooms via a separate set of “return” ducts and toward the heat exchange (where it is again heated or cooled). This circular cycle continues until the desired temperature is reached. Here’s a good guide on how often you should change your air filter. When your air filter is clogged, your air handler must work harder to compensate for the blockage of air flow. In addition to driving up your utility bill, the reduced air flow through your heating and cooling system can cause your heat exchanger to overheat and shut off too quickly, preventing your house from warming up. If that happens too often, the electronic "limit switch" safeguard can fail, and then the furnace won't fire up at all. This service call and new part can easily cost you $175. So what’s the big deal? Does an air filter really matter?  In an effort to answer this, let’s take a look at what happens if you do not routinely change your heating and cooling filter. 

Here are some clogged furnace filter symptoms: Because the system relies on the constant recirculation of air, the performance of your heating and cooling system’s blower fan can have a big impact on your home’s energy consumption. The harder this fan has to work to draw air throughout your home, the higher your energy bills will be. In fact, a clogged filter can use 15% more energy, according to the Department of Energy. This inefficiency increases quickly as the filter becomes more and more clogged, or until the filter is serviced. If your air filter clogs during the summer cooling season, this can cause the evaporator or cooling coil to freeze up because not enough air is moving past the coil to dissipate the condensation that is normally produced during the cooling process. Lack of adequate airflow causes this condensation to freeze – reducing the unit’s ability to remove heat from the air (e.g., cool your home) and, most likely, eventually causing your air conditioner to break down.

Blower fans push the air through the filter. If the filter becomes too clogged with dust, dander and debris,then the blower has to strain harder to pass the air through a clogged filter. With reduced airflow you can experience hot and cold spots in your home, and it can be difficult to reach your desired indoor temperature levels. With less air flowing through the system due to the clog, the central air conditioning and heating system will run longer in an effort to heat the home, raising energy usage. does air purifier really workIn fact, according to a study by the Florida Public Service Commission, the number two cause of high energy bills in the summer was a clogged air filter.best type of air purifier for mold A clogged air filter will allow all that dust and debris that should be filtered out to be re-circulated back into your home. clean air car check ontario

This can cause chronic allergies and especially be dangerous for people with asthma or other respiratory conditions. If you own pets or keep many chemicals around the house, the indoor air quality will be even worse with a clogged filter. You might not notice a sniffle here or there, but over time, poor indoor air quality will impact your health in a very negative way. Can a clogged air filter cause a heater to stop?  The answer is yes, and likely the costliest result of an improperly changed air filter may be the internal damage it deals to your central air conditioning and heating system. According to the Diamond Certified Organization, a clogged furnace air filter is the primary cause of equipment failure. Essentially, that overworked air blower discussed above may give out entirely, causing the whole system to fail, an outcome that can cost thousands of dollars to repair! Here’s a good guide to know how to change your home air filter. Check out how valuable clean air filters are for your home:

When you think how much can go wrong when you have clogged air filters, you take to heart the benefit that an air filter clog detector offers. While I know a lot about cars, I don't know a lot about YOUR CAR! If you are looking for vehicle specific instructions, an online repair manual is the ticket. I recommend Alldata or Mitchell1, but also have a cool way to get a free repair manual, you need to check out today. Nothing stinks more than having your Air Conditioning go out while on a long summer trip. Of course I could tell you to get the system checked BEFORE you ventured out, but what good would that do now? There is not much you can do while driving to help when your A/C system has pooped out on you. There are a few things you could check though... make sure the condenser is free from obstructions (usually sits right in front of the radiator.) Check belt tension for the compressor, and make sure the clutch wiring is connected properly. Fan only blows two speeds, OFF and Full Bore?

Most likely your resistor is shot. The fan circuit has a resistor which controls the speed of the fan blowing air through your vents. When they go bad, you only have one speed, full blast. Usually an affordable fix, the hardest part is finding the location of the resistor under the dash. The HVAC system is complex to say the least. You need a repair manual to guide you to the specifics of maintaining and repairing your HVAC system. Checkout Mitchell1 for the best online repair manuals.

They come to your house or place of work and get you fixed up without the hassle of taking the day off or being without your car. Without the heating and air conditioning systems in today’s modern vehicles, we would all be miserable driving to our destinations. We take for granted the heat that keeps us warm in the winter months, and the cool air that refreshes in the summer time.

Let’s take a look at how both systems work to keep us comfortable all year round. The heater in your car is basically a smaller version of your cooling systems radiator. Hot engine coolant is circulated through a small radiator, often times called a heater core. A fan is positioned in front of the heater core to blow cold outside air over the fins. As this air travels over the heater core, it heats up and becomes the hot air which blows out your heater vents. Like your engines cooling system radiator, the heater core can suffer some of the same issues. If the heater core becomes clogged with rust or sludge, you will no longer have heat. Also leaks can cause a cabin full of white steam and really mess up your windows. If you smell the sweet aroma of coolant when your heater is on, chances are, you have a small leak in the heater core. Often times the heater core is buried under the dashboard, and replacing it, is a major job. The air conditioning system in your car is comprised of a compressor, condenser, expansion valve and evaporator.

If you have ever used a can of compressed air to clean computer components, you will know that the bottle gets very cold in a short amount of time. This is due to the rapid expansion of the compressed gas. The same thing happens in your car’s air conditioning system. Refrigerant (AKA Freon) is compressed in the compressor and turns into a hot gas. In the condenser, this hot gas is cooled to a liquid state and travels to the expansion valve. As the Freon goes through the expansion valve it returns to a low-pressure gas and rapidly cools in the evaporator. A fan blows over the evaporator and cools the air that eventually blows out your vents. Click Here For An Excellent Illustration and Further Explanation. From time to time the A/C system needs to be recharged to bring it back up to maximum efficiency. Sometimes a leak may cause loss of refrigerant and will need to be fixed before refilling. It's difficult to tell if a leak is present without specific test equipment so let it up to a professional.
