Few things are as unbearable as a broken air conditioner during winter or summer. It could make you avoid your home, literally. Sometimes, the problem may not be major. By figuring out where the malfunction is, you could do the air conditioner repair the DIY way, and save some money.
Here are some common problems that occur in air conditioners, and ways to fix them.
Problem with the Thermostat
The thermostat’s work is to detect the temperatures of the home and turn the air conditioner on and off. First, ensure that the issue is not in the settings.
The thermostat should be placed at a central and neutral location. Placing it at a point that receives direct sunlight or cool air such as near the window and air vents could make it detect wrong temperatures. If the thermostat is cooling the house when it should be warming it and vice versa, check its location.
A faulty thermostat
A thermostat that is not lit on the display, one that won’t change the house temperature when adjusted, or does not put the AC on and off could be faulty. There could be a wiring problem or the batteries may need changing.
For a mechanical thermostat, try cleaning it. Dust could make it malfunction. For an electrical thermostat, change the batteries. Remove the cover and ensure the wires are not loose.
A clogged filter will restrict air flow in the AC causing the evaporator coils to freeze. It makes it impossible to achieve your desired house temperature. You are likely to experience hot and cool episodes.
Since the condenser coils are located outside, they could also accumulate dirt restricting air flow. Clean and change your filters regularly. Use coil cleaner on your condenser coils for an efficient cooling system.
Failure to clean the dirt buildup could cause your air conditioner to overwork, overheat, and shut off.
When the Air Conditioner Does Not Switch On at All
The problem could be in the main electrical panel. If the breaker has tripped, turn it off and then on, this should fix the problem. Replace the fuse if it has blown.
If the breaker continues to trip, there could be a problem in the wiring system. Do not turn it on again. Get an electrician or HVAC (Heating, Air Conditioning, and Refrigeration) technician to fix it.
Problems That Will Need a Technician
If the air conditioner is making unusual noises when running, it could have bad bearings. The problem is best left to the technicians.
A refrigerant leak is also a common problem with air conditioners. It causes your electricity bills to shoot. In this case, you will need an HVAC technician to refill it. Ensure that they find the point of leakage as well and fix it.
In conclusion, before calling a technician for an air conditioner repair, ensure that it’s not a problem you can fix.
Switch the power off before attempting any repairs. If you do not understand something, leave it to the experts. Most importantly, sign up for annual maintenance with an HVAC contractor to prevent frequent air conditioner repair issues.
