Strange noises (rattling, buzzing, grinding)
Weak airflow or uneven heating
Heat pump stuck in one mode (heating or cooling)
Thermostat or sensor problems
If it’s not performing like it should, we’ll identify the cause and recommend the best fix.

Thermostat settings or calibration issues
Outdoor unit icing or defrost problems
Electrical or control problems

Repair is usually best when:
The issue is isolated and the system is otherwise in good condition
The heat pump is maintaining comfort most of the time but has developed a specific fault
Replacement may be worth considering when:
Repairs are frequent and costs keep stacking up
The system can’t keep up even after service
You’re paying for repeated “band-aid” fixes

It can happen due to defrost cycles, airflow restrictions, thermostat issues, or system performance problems. A diagnosis will pinpoint the cause.
Light frost can be normal, but heavy ice buildup may indicate a defrost or airflow issue.
Short cycling is when the system turns on and off frequently, which can reduce comfort and increase wear.
Only if your system requires it due to a specific issue. If you’re unsure, call for guidance—running emergency heat unnecessarily can increase energy use.
