We understand that many Coachella Valley homeowners are reluctant to call for heating or cooling repairs because of the expense involved and because many people don’t want some stranger coming into their house during these times. However, there are many things you can look for so you can fix many heating and cooling issues yourself instead of relying on a professional technician. So, here’s how to troubleshoot your heating or cooling system. Check the Air Filter Dirty air filters are probably the most common problem we see when repairing HVAC systems, and it’s one that is easily avoidable. When the air filter is dirty, it impedes airflow into the system, making it work harder, which burns more energy. And, sometimes the filter is so dirty, that the system just can’t function anymore. So, before you call for an emergency air conditioner or heating repair, check to make sure your air filter isn’t the issue. Check the Thermostat Many times, you can avoid calling a repair technician when your system won’t kick on simply by checking that the thermostat is properly set to the correct mode. Also, if you have a programmable thermostat, check the batteries to see if they need replacing. Most thermostat issues are easily remedied by checking the owners’ manual before calling for professional help. Check the Electrical System If you’re not getting power to the system, check with the basics and see if there’s been a breaker that’s been tripped. Also, check that the on/off switches near the indoor air unit and near the compressor. Check the Overall System Do a detailed inspection of your heating or AC system. Examine the condensate drain line for clogs, and check the air vents to make sure none are blocked Also, or AC issues, check the outside air compressor to make sure it’s free from debris. If you’ve checked everything but still have problems, then it’s best to call a professional for expert diagnosis.
