Common HVAC Problems

HVAC units are widely used by families all over the United States. They keep homes cool in the summer and warm in the winter. But they aren’t perfect. They sometimes run into issues that make them less efficient. If you have an HVAC unit then you may want to know some of the most common HVAC problems you may run into. Before you call an expensive repair man check out our list of the top 5 most common problems with HVAC units

1. Thermostat issues. Many times when people think their HVAC unit is not working properly they forget to check one of the most obvious areas of control, the thermostat. Check to make sure your thermostat is turned on and make sure it is not set incorrectly.

2. Capacitors. Capacitors keep the motor running at the set speed with consistency.  Often these capacitors will burn out causing a slowing down or even completely stopping the unit from working. If your HVAC goes from barely working to not working at all a technician may determine that the capacitor has burned out and needs to be replaced.

3. No refrigerant. Often a broken HVAC really is not broken at all. It may simply need a dose of refrigerant. Of course if an HVAC is running out of refrigerant it can point to a leak somewhere in the hose lines. If that is the case then an inspection must be done of all the vales and they must be adequately sealed to prevent further leakage. It is important to get this checked out immediately because low refrigerant can cause the compressor to blow.

4. Fuses blown. Blown fuses are one of the most common problems with residential units. Blown fuses can be caused by a number of factors including an overheating of the unit. The compressor of the unit will create so much energy and heat that the fuse blows because it cannot handle that kind of output. Most often this is the first place a technician will look if you call him out to fix your unit.

5. Clogged filters. Filters are so vital to the unit because they allow constant necessary air flow into the HVAC. If your filters are clogged and dirty you must replace them or they can cause your unit to freeze up, making it an even more costly problem to fix.

Remember to always check these common problems first before you call a technician out. You may save yourself time and money in the process.
