Frequently Asked Questions
How much does the diagnostic visit cost?
The diagnostic visit is $80. If you move forward with the repair, we put that knowledge to work right away.
My AC blows warm air — what could it be?
Common causes include low refrigerant, a dirty condenser coil, a failed capacitor or a thermostat issue. We test the system to find the exact cause.
My furnace keeps turning on and off. Is that normal?
Short cycling usually points to a thermostat, airflow or overheating issue. It is worth having checked before it puts more wear on the system.
Should I repair or replace my HVAC system?
If the system is relatively young and the repair is straightforward, repair usually makes sense. If it is aging and repairs keep adding up, we explain the replacement options.
Why is one room hotter or colder than the others?
Uneven temperatures can come from airflow restrictions, duct issues, thermostat placement or system sizing. We inspect the system before recommending a fix.
