Air Conditioner Ice Build Up Does your air conditioner have a build up of ice on the outside? Wondering what could be the cause or fix for this? Read on to find out! Restricted Air Flow The major cause of ice build up on an air conditioner is restricted air flow. Without the proper air flow being able to flow over the evaporator coil, the temperature will easily drop below freezing and ice will begin to accumulate both inside and outside. Most people only notice their outside unit being frozen but chances are if you our outside unit is a block of ice then so is the evaporator coil that sits on top of your furnace out of view. R-22 refrigerant works to cool your home by making your indoor coil extremely cold as warm air blows over it. The best way to prevent ice build up on your air conditioner is by regularly changing your filter and keeping it clean. If your furnace filter is clean, there is a chance that your evaporator coil may be clogged with dirt, hair ect. If you have never had this cleaned in the past, it may be time. Other items that can cause your air conditioner to freeze: Blocked drain pipes Refrigerant leaks Low temperature outdoors Night time setting of your thermostat is too low Signs Your Evaporator Coil Is Frozen As previously stated above, if your outdoor unit is a bock of ice, chances are so is your evaporator coil. Signs that...

Why Does My Air Conditioner Smell Bad? Have you recently turned on your air conditioner only to find your house smelling foul a few minutes later? Dirty Sock Syndrome There is nothing worse than coming home on a hot day and walking into an air conditioned home that smells like a dumpster. If you have just turned your air conditioner on for the first time of the year, this is popularly known as "dirty sock syndrome" and is due to dirt and dust growth on your evaporator coil. If your air conditioner is creating foul smelling air all of the time however, there could be several things occurring. Here are a list of the most popular odors and their likely culprits. Air Conditioner Smells Musty If your air conditioner smells musty when you turn it on, you may have dust, mold or mildew growing in your duct work or indoor coil. Mold thrives in cool, damp and dark areas and the duct work and indoor coil of your home are prime culprits for this to occur. Your air conditioner's job is to actually remove humidity from your home and when that humidity cannot drain properly, mold will begin to grow over time. The only remedy to these issues is to have your duct work cleaned every few years and have maintenance performed on a regular basis to ensure no water is accumulating in the wrong spots. It is also possible to have your evaporator coil cleaned as well to ensure...

Fixing an Air Conditioner Refrigerant Leak Did you know that it's technically possible to fix a leak in an air conditioner? Although it may not be the most cost efficient repair to make based on the age of the unit, fixing a leaking air conditioner can buy you some extra time to get the money needed to have a new one installed. Let's take a look at what all goes into repairing a refrigerant leak in an air conditioner. Determining the Type of Refrigerant This first step is extremely important due to the fact that putting the wrong refrigerant in your air conditioner will destroy the compressor. You will need to determine the age of your air conditioner to verify what type of refrigerant it is using. If your AC was manufactured before 2010 then it is most likely using R22, the old and now phased out refrigerant. If it is newer than 2010 it will utilize R410-A refrigerant. Locating the Refrigerant Leak Evaporator Coil By far, the most common place for a refrigerant leak to occur in an air conditioner is at the indoor evaporator coil. This coil sits on top of your furnace and is what absorbs the heat from the indoor air before sending it outside to be dispersed. This coil which is shown below, is also commonly called an "A-coil" due to it being the shape of the letter "A". Most refrigerant leaks are very small pinhole sized leaks that can only be detected by a...

Is It Possible For My Air Conditioner To Give Me Headaches? Believe it or not, air conditioning can actually be the cause of headaches for some people. Cold Air Can Cause Dehydration Did you know that your air conditioner not only cools the air in your home but also acts as a large dehumidifier as well? Yep! While lowering the overall humidity indoors is a good thing during the hot summer months, lowering it too much can cause dehydration which will in turn lead to head aches. Even mild dehydration can cause headaches so be sure you drink plenty of water even though you are inside your cool home. Another option is to have a humidifier installed that will work with your HVAC system to keep your home at a constant humidity level.  Cold Air & Blood Vessel Contraction If you keep your home too cool, it can actually cause the blood vessels in your head to start to contract causing a headache. Most home cooling modes are set anywhere from 69-72 degrees. If you have your thermostat set much lower than this, try turning it up a few degrees to give your head a break. Mold & Other Pollutants Mold is well known for causing headaches if the concentration is high enough. Your HVAC system can be a prime spot for mold growth in the summer due to it's damp, cool conditions. The most likely place for mold to grow is on your evaporator coil which sits on top...
