Faulty Thermostat

If your air conditioner isn’t working correctly, it might be the fault of your thermostat. Your AC might refuse to turn on, or it might keep your home at the wrong temperature. A broken thermostat may simply not be sending the right signals to your AC unit. Luckily, thermostats are a pretty easy and inexpensive fix, usually costing less than $100.

Dirty Filters

Most air conditioners stop working because of a lack of regular maintenance. One of the easiest ways to keep yours in good running order is to make sure you change your filter on a regular basis. This is typically every 1 to 2 months, depending on how often you run your AC. It also depends on how many pets are in the home, since dog and cat fur can clog filters more quickly.

Dirty Coils

Your air conditioner’s evaporator and condenser coils play a big part in removing heat from the air and keeping your AC pumping out cool air in return. Even a very thin layer of dust or dirt on the coils can significantly reduce their performance. If they get too dirty, your AC may not be able to produce cool air at all. If you can feel warm or lukewarm air being pumped out your vents, this might be the problem. Once again, this is a problem that can usually be prevented with regular AC maintenance in Littleton.

Damaged Parts

Your air conditioner has a number of moving parts that get worn down over the years and occasionally need to be replaced. Hire an AC service in Littleton in late spring before you start using your AC for the season. The technician can clean and inspect your system, looking for parts that need to be replaced. This way, the system will be less likely to break down on you when you need it most.

Clogged Condensate Line

Not only does your AC keep your home cool, it also keeps it less humid by removing excess moisture from the air. Your condensate drain line is where that moisture leaves the AC unit. It’s usually located next to your furnace–you can spot it by looking for the drain pan that collects the water. When the drain line gets clogged with mold or other debris, it can cause water to back up into your AC and cause it to stop running. An AC service in Littleton can check yours during their annual inspection to make sure it’s free from debris.
