"He serviced our HVAC system. House was dormant for about 9 months and for sale. We noticed the system didn?t smell good and wasn?t cooling the house right. So we called him to service our house. He found our duct work to be compromised and pulled out some dead animals. He fixed the ducts and put this shiney metal tape on all the seams. Checked the AC outside for refrigerant gas and operation. Then he checked our furnace inside. The filter was black and musty, he didn?t have our size on his truck but he ordered a couple from Walmart and had them delivered while he worked on our furnace blower. He found the round fan was all clogged with hair and dirt. He pulled it out and cleaned it outside, used some chemicals that made it shiny and cleaned. Checked the fan blades with a tool to make sure it was blowing a strong stream of air. Took a shop vac cleaned each of our floor vents and put about 10 or 15 foot of hose going in each direction. For a man by himself he was very"

Air Conditioning questions, answered by experts

Yes, a dirty evaporator coil can freeze up. Dirty evaporator coils can’t absorb or transfer heat properly. The dirt and grime restrict airflow, which is needed to move heat throughout the system properly. Your air conditioning unit could freeze over, or it can cause your heat pump to freeze.

A 3-ton AC unit is probably too big for a home that’s 1,200 square feet. If you have a 1,200-square-foot home, you likely need a unit that’s somewhere around 1.9 and 2 tons. An AC unit that’s too large will be really inefficient and cost you a lot of extra money on your bills. 

The compressor is the heart of your AC system and is one of the most important parts required to keep it functioning properly. If your AC unit is making a popping, banging, clanging, clicking, or screeching sound, it could point to a problem with the compressor. If the unit is physically vibrating, that can also be an indication that your AC compressor is going bad.

Look up your model number online to find additional information. Usually, you can just take a look at the old filter and find the brand name and dimensions to order a new one. When replacing the filter, always check that it’s pointed the right way to match the direction of your airflow. Many filters have arrows on them to help with this step.

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home.
