Before you call
AC Troubleshooting Tips Before Scheduling Service
Some air conditioning issues may have simple causes. Before booking a service call, the following steps may help identify the problem.
-
Check the thermostat
Ensure the thermostat is set to cooling mode and the desired temperature is below the current room temperature.
-
Check the circuit breaker
A tripped breaker can interrupt power to your system. Reset it if necessary, and call us if it trips again.
-
Check the furnace filter
Dirty filters restrict airflow and strain the system. Replacing filters regularly can prevent many performance problems.

Repair or replace?
When to Consider a New High-Efficiency Air Conditioner
If your air conditioner is more than 10–15 years old, requires frequent repairs, or no longer provides consistent cooling, replacement may be worth considering.
During a repair visit, our technicians can assess whether continued repairs make sense or if upgrading to a newer high-efficiency system may provide better long-term value. If replacement becomes the better option, we’ll walk you through available systems and next steps.
