3 Possible Reasons Your Circuit Breaker Always Trips When Your Heat Turns On

Is your heating and air conditioning equipment overloading your fuses?
​
Does your home blow a fuse whenever you run the heating and air conditioning? As stressful as this might seem, don't despair. The solution is usually simple and more affordable than you fear.

1. Loose Connection

Like every other building material in your home, the electrical components running from the HVAC to the breaker box expand and contract as temperatures change. As they shrink and swell, connections get loose. When electricity flows through loose connections, they heat up enough for breakers to trip and fuses to pop.
​
Call an HVAC company like Smoak's Comfort Control or an electrician to diagnose and resolve the issue. Do not try to tighten the components yourself without shutting off the main power breaker to the house and grounding the wires.

2. Blocked Airflow

HVAC equipment depends on airflow to work properly. Restricted airflow leads to all kinds of problems. Without it, your pilot light might struggle to stay lit, and the air coming out of the vent might be cold. Low airflow can also cause your system to overwork and pull in too much electricity for the components to handle. This can trip your circuit breaker.

Dirty filters, clogged ducts, and closed vents can all restrict airflow. Clear them to keep your system from overheating and your fuses from blowing.

3. Short Circuit

​When electrical components become worn or frayed, they can interact with one another, causing a short circuit and a blown fuse. Call a trusted HVAC technician to fix the problem and prevent it from happening in the future through preventive maintenance visits.
​
One thing to note – it’s not a good idea to simply reset your system and ignore when it trips a breaker. In each of the above situations, continued use could lead to a fire.
