5 HVAC Troubleshooting Tips Everyone Should Know

HVAC Troubleshooting

If your HVAC system suddenly stops working or you notice high utility bills out of the blue, it could mean trouble. Before you call in the pros, use these 5 HVAC troubleshooting tips every homeowner should know.

1. Check the Air Filters

Leaving air filters in too long can cause your HVAC system to run inefficiently and even stop working. Over time, the air filters collect debris, allergens, pollen, pet hair, human hair, dust, and dirt. Eventually, the debris will make it so air can no longer pass through the filter. This, in turn, will cause your HVAC to run poorly and reduce your home’s air quality.

Depending on the manufacturer’s recommendation, you should change air filters every 30 to 90 days. Check the filter after 30 days and then every 15 days after. If the filter media is gray, the system is cycling longer than usual, or you notice more dust around your home, it’s time to change the filter.

2. Check the Thermostat

The thermostat controls the HVAC system temperature and how often it should run. If the thermostat isn’t working correctly, it can cause the HVAC to run inefficiently or not run at all.
Check to see if the thermostat has power. If it’s battery-powered, the batteries may need to be changed. You might have to reset the thermostat according to the manufacturer’s instructions. Avoid setting large temperature fluctuations, which can cause the HVAC to run unnecessarily or cause other problems.

3. Clean Around the Outside Unit

People often forget the unit outside is part of the HVAC inside. Both have to function correctly to keep your home heated or cooled. Clean out debris, including grass, fallen tree branches, pine needles, and leaves from around the outside unit. Check the outdoor unit regularly to ensure nothing comes into contact with it. This will prevent debris from clogging the outside unit, causing the entire system to malfunction.

4. Check the Circuit Breaker

A tripped circuit breaker could be one of the most straightforward solutions to your HVAC system problem. If you go to your home’s circuit panel and notice a tripped breaker where the HVAC is located, this is probably your problem. Reset the breaker to the on position, then wait to see if the HVAC system comes on. Suppose it doesn’t, and you’ve already checked that the thermostat is on and working correctly. In that case, it’s time to call a professional to check the system.

5. Check Ducts, Vents, and Registers

Your HVAC system also includes ducts, registers, and vents. Over time, debris particles can build up in these components, blocking airflow and reducing efficiency. You should clean registers and vents seasonally, while ducts may only need cleaning every few years.

Avoid blocking return registers or vents with any objects, like furniture. While the vents and registers may not be aesthetically pleasing or in the most convenient locations, they serve a purpose: circulating the air in your home. You want to ensure plenty of open space around all vents and registers so air can move freely.
