What To Do Before Emergency HVAC Service Arrives
Taking a few simple steps before your technician arrives can help protect your HVAC system and make the repair process more efficient. If you believe your equipment is unsafe, turn it off and avoid attempting repairs yourself.
-
Check Your Thermostat Settings. Make sure your thermostat is set to the correct mode and temperature before assuming the system has failed.
-
Inspect The Circuit Breaker. A tripped breaker may prevent your heating or cooling system from operating. If the breaker continues to trip, leave it off and wait for a technician.
-
Replace A Dirty Air Filter. A severely clogged air filter can restrict airflow and contribute to heating or cooling problems. Installing a clean filter may improve system performance in some situations.
-
Turn The System Off If You Notice Burning Odors. If you smell something burning or hear unusual electrical sounds, shut the system down to help prevent additional damage until it can be inspected.
-
Make Note Of Any Warning Signs. Pay attention to unusual noises, error codes, leaks, or when the problem started. Sharing these details can help your technician diagnose the issue more efficiently.
