5 Common HVAC Problems & How to Fix Them
When temperatures soar in San Diego and your air conditioning system chooses to stop working with little to no warning, you need a quick solution. Although most air conditioning problems require the knowledge of an HVAC professional, homeowners can also troubleshoot some issues.
To help you stay comfortable in your San Diego home, consider these five common HVAC problems and how to fix them.
Clogged Drain
If there’s too much humidity in your home, the condensate from the evaporator coil is collected in the condensate pan, and then poured into an indoor or outdoor drain. If either the pan or the drain is clogged with debris, water in the pan will back up and shut down your A/C unit. Make sure your A/C system is clean and properly mounted both indoor and outdoor.
Dirty Filter
A dirty filter is caused by dust buildup in the evaporator coil, preventing airflow and reducing absorption of heat. Additionally, dust buildup on the fan and compressor can cause a premature system failure. Inspect the filter after 30 days and change it when it’s caked with dust to cut down allergens.
Leaking Refrigerant
Check your air conditioner’s refrigerant levels regularly. If it’s too low, it may have been slightly undercharged during installation. Contact a professional to locate any leaks and to repair and recharge the refrigerant levels as indicated by the manufacturer.
Broken Thermostat
If your air conditioner is regularly running, but your home is still hot, check the thermostat. A malfunctioning thermostat will indicate a lower temperature different from your home’s actual temperature. If resetting it doesn’t work, contact a technician.
Electronic Control and Sensor Failure
These are probably the first elements of an A/C system to wear out, particularly if your unit is oversized. Check the connections, and ensure they’re still in place.

Sherlock is the coolest! As always, Yelpers are right on. Basing my picks on high stars and number of reviews, I called four companies. Right off the bat, I knew one company wasn't even an option due ...
This is a review not so much for Sherlock, but for Fred Radtke - the young man that came and got my heater working. He not only installed a new thermostat on the spot that is easier to read - and repl...

Ahhh! Cool and comfortable in our house now. Thank you to the awesome guys who installed this high quality equipment. Good to have Costco stand behind them, too.
There is a reason this place has nothing but five stars. They earn it! I have had no AC in the house and was procrastinating on getting it fixed due to the cost and lack of need most of the year. I wa...

Buying HVAC for an entire house is not an investment to be undertaken without some research. It's probably going to cost more than $15K and will require a crew of techs working in your house for sever...
