Common AC System Repairs You May Have To Deal With When Your Air Conditioner Can't Keep You Cool
When your air conditioner isn't keeping your house cool, the AC repair technician has to consider several different things. Your AC system consists of the thermostat, ducts, condenser, and air handler. These contain electronic parts, wiring, refrigerant, coils, fans, capacitors, and a compressor. A minor malfunction can affect your AC just as much as a major problem, so the technician has to troubleshoot the system. Here are some common problems and repairs to consider.
Leaks In The Ducts
You might forget all about the ducts since they're not easily visible, but they play an important role in keeping your house cool. Ducts can sometimes come apart at the connection seams, and this allows cool air to leak out in the hot attic. That leaves less cool air to chill down your living area. Fortunately, fixing a leaky duct is an easy repair that can be done by patching the gap or hole.
Bad Thermostat Wiring
Thermostat problems are sometimes easy to fix too. Dust might be clogging the insides, in which case, the technician can blow the dust out of the way so it won't interfere with the operation of the thermostat. Another common problem is loose wiring. If the wiring is loose, the thermostat may be erratic when controlling the AC. Loose wiring can be tightened or replaced to solve this problem.
Dirty Or Leaky Coils
Problems with the evaporator or condenser coils can be a more complex AC system repair. If the evaporator coils are dirty, the AC may ice over. At the least, the refrigerant won't be able to cool your home as well. If the condenser coils are dirty, they won't be able to cool down the refrigerant, and that affects how well the AC can cool your house. Dirty coils can be cleaned so they work optimally.
However, a hole in either set of coils is a more serious problem since a hole lets refrigerant escape. When the refrigerant level drops, your air conditioner won't be able to cool your home. The repair technician has to find and repair the hole before the refrigerant can be filled.
The condenser and air handler fans are also essential parts of your AC that can malfunction. The fan may not work if it's coated in dust or dirt. The condenser fan might even get damaged by debris since it's outside. Another cause of fan trouble is when the motor goes bad. This might happen if the motor overheats due to a problem with the fan or a failing capacitor.
The repair person might need to clean the fans, service the motors, or even put in a new capacitor to get the fans operating at normal speed and without straining the motor.
One of the most expensive AC system repairs you might face is when the compressor goes bad and has to be replaced. Sometimes, a compressor goes bad because it is stressed by other malfunctioning parts, such as the condenser fan or dirty coils. That's why prompt repairs are important when your AC isn't working properly. Fixing a bad part or cleaning dirty equipment early could save you from having to buy a new compressor.
