Circuit breakers are designed to “trip” or cut power during power surges or when the load exceeds normal limits. When your HVAC system causes your circuit breaker to trip, take a moment before you call your local heating and air conditioning contractor. If it occurs only once every season, it may not be a cause for concern. However, if it happens too frequently, then your system may be suffering from unseen problems.
It’s not always easy to determine why your heating or air conditioning unit might be tripping your circuit breaker. Only a professional can help you detect any problems that may be causing your system to overload your electrical supply. Our professionals at Richardson Air Systems suggest following these tips when your HVAC system trips your circuit breaker too frequently.
Change your filter. Clogged filters restrict airflow in HVAC systems, which is why many cooling and heating contractors recommend cleaning or changing them at least once every 30 to 90 days. Poor air circulation due to a clogged filter can often cause your blower fans to work harder, drawing more power than normal from your circuit breaker, which in turn causes it to trip. The same is true for blocked vents and registers. This is why you need to move any furniture that may be obstructing your duct system.
Compressors and heat pumps. If you have a heat pump system, the compressor requires occasional lubrication to function correctly. Neglecting compressor maintenance can cause it to “tighten up.” This leads to overheating of the motor. In worst case scenarios, it could even burn out the compressor, which is expensive to replace. Constant tripping can be a sign of compressor problems in your heat pump.
Electrical issues. Sometimes, the problem isn’t in your residential or commercial HVAC system but in the electrical components themselves Frayed wires and faulty connections are notorious for causing shorts and tripping breakers. Contact your local electrician for a thorough inspection of your electrical system if this problem happens regularly.
