What Are Common Signs My Home HVAC System Needs Repairs?

A: The four that matter most are a system that runs constantly without reaching setpoint, a hard electrical hum or grinding from the outdoor unit, airflow that has gone weak at every register, and a bill that jumped without a change in the weather.

What they usually point to, and what those repairs run in our published ranges:

• Outdoor unit hums but the fan won't start — often a capacitor, $150 to $400
• Unit clicks on and off, or won't engage at all — contactor, $150 to $350
• Cools poorly and ices up on the line — refrigerant leak, $250 to $1,500
• Weak airflow at every vent with the fan running — blower motor, $350 to $900

That is a starting map, not a diagnosis. Our diagnostic is $95, and it is waived if you approve the repair on that same visit. Full ranges are at hvac-repair-cost. To get on the schedule, call 405-420-4895.
