When your heating, ventilation, and air conditioning (HVAC) system shuts down unexpectedly in your Charlotte County, Florida, home, don’t panic. You might not need a brand-new system. In fact, the problem can boil down to something as simple as a clogged air filter. Unfortunately, dirty air filters often wreak havoc on the entire HVAC system.

Reasons HVAC Systems Shut Down

Sometimes, HVAC systems stop working because of a serious mechanical problem. The blower could burn out, for instance, or the control board wiring could fail. However, clogged air filters can render an HVAC system inoperable just as quickly because your air conditioner, furnace, heat pump, or other equipment relies on airflow to continue working. If airflow is impeded, the system can’t circulate conditioned air into your home efficiently.

Over time, the air filter draws in pet dander, dust, dirt, and other contaminants. That’s its job. However, if the fibers get too clogged with debris, the HVAC system can’t pull air through the filter. Eventually, this can cause the system to shut down.

Signs of Clogged Air Filters

If the system turns off after running for just a few minutes, then starts again, the air filter might be the culprit. Other signs include reduced airflow in the home and poor temperature control. Remove the device and inspect it. You will be easily able to tell if it needs to be replaced. The filter will be covered with dust, dirt, and other debris. Simply install a new air filter and start the system again.

Getting Professional Help

Replacing the air filter might not resolve the problem. If your HVAC system continues to run sporadically or not at all, we can send out a technician to investigate the issue. When homeowners repeatedly forget to change the air filter, the system is subject to extra wear and tear that can cause other malfunctions.

In addition to changing your air filters, you might need us to clean your ducts. For information about HVAC services and to troubleshoot your issue, call Custom Air & Plumbing at 888-856-4507.
