5 Common AC Problems and How You Can DIY

Common AC problems and how to solve them

You get home and you want to relax but your air is not functioning properly. Maybe it’s not cool enough or perhaps you hear a loud noise.  There are several simple things you can do if your ac stops working before you call for repair.  Here are some common issues and how do deal with them.

Air Conditioner will not switch on

Check that there is a supply from the main electrical panel. There could be a fuse blown or breaker tripped. The air conditioner should be on a separate circuit. If the breaker is tripped just turn it back on and your unit should turn on.  If not, then you will need to call for service.

Thermostat

Turn power off to the thermostat, remove the cover and check the batteries (if fitted). Re-assemble and switch back on after a few minutes.  If the batteries are okay and the unit still will not switch on then it could be dust in the thermostat.   The best cause of action now is to call a qualified HVAC technician to have your thermostat checked and repaired or replaced.

Poor Cooling Performance

There are number of issues that can cause poor cooling, the most common being a blocked or dirty filter.  Replacement is a simple procedure:

• Turn off power to the unit
• Open the air handler door or remove the cover and remove the filter. Depending on the type you have fitted, it may be possible to clean the filter, otherwise, replace it.
• Check for ice. If you find ice around the coils, replace the filter cover, reapply power to the unit and leave running for a couple of hours. The ice will melt naturally.

Check that the compressor is working by dropping the thermostat temperature to low and checking that the compressor starts up. If not then you need to call an air conditioning technician for more detailed testing.

Air Conditioner is noisy when running

Most modern air handlers have a direct-drive motor, but belt driven systems still exist. If the belt becomes nonaligned or loose, it makes a squealing sound. Repair or belt replacement is needed by a professional.

If the air conditioner has a direct drive system, and you can hear squealing or grinding, the likelihood is that the motor bearings are worn or damaged. You should switch the air conditioner off and call an HVAC engineer immediately.

Occasionally, your air conditioner will make squeaks, pops or small banging noises, which is usually due to the expansion of metal ducting. There is little you can do about this situation other than have a heating contractor fit insulated flexible ducting to minimize the noise. It is also worth checking that the furnace and handler doors are shut correctly as they can cause vibration noise.

Some of the issues discussed, you can fix yourself, but some do require the attendance of a qualified air conditioning technician.
