Check Your Air Filters Regularly

Air filters are the most common cause of HVAC problems. Dirty air filters restrict the airflow needed for your HVAC system, causing it to work harder than it should, and potentially, damage the unit. Dirty filters can also lead to higher energy bills and reduce the lifespan of your HVAC system. As a rule of thumb, you should check your AC filter every month and change or clean it according to the manufacturer’s recommendations.

Test the Thermostat

If you notice that the air coming out of the vents is not the right temperature, you should first check your thermostat settings. Make sure the thermostat is set to the correct temperature and that it is in the ‘on’ position. You should also check if there is a problem with the power source, especially if the thermostat is battery-operated. It’s also wise to consider upgrading to a programmable thermostat. This will give you more control over your HVAC system, allowing you to save energy and money.

Check the Power Source

Before you conclude that your HVAC unit is faulty, you should check if the unit is receiving power. If your HVAC system is not turning on, especially after a power outage, check if the circuit breaker is tripped or if there is a blown fuse. Resetting the breaker or replacing the fuse can solve the issue, but if the problem persists, seek the advice of an HVAC professional.

Check Your Condenser Unit

You should also check your condenser unit if the system appears to be working but not producing enough cool air. A dirty or clogged condenser coil can prevent your HVAC unit from working efficiently. Clean any debris like grass, twigs, or leaves that surround the condenser unit. You should also have the evaporator coil cleaned at least once a year.

Check Your Ducts

If you notice that your HVAC unit is working harder than usual or is noisier than normal, this could be a sign of ductwork issues. Damaged, loose, or leaky ducts can reduce the efficiency of your HVAC system and reduce its lifespan. Check your ductwork for holes, leaks, or other damages like loose tape or connections. If you notice any problems, consider contacting an HVAC professional to repair or replace the ducts.
