Ac Repair FAQ

Why is my AC running but not actually cooling the house?+

Turn the system off, set the fan to run, and call — running a frozen coil makes the underlying problem worse.

How much refrigerant does my system actually need?+

Adding refrigerant without finding the leak just means another service call later.

Can you service older R-22 systems?+

We carry recovery equipment rated for legacy refrigerants.

Do you work on ductless mini-split systems?+

Yes — indoor head units, outdoor condensers, and line sets all fall under our service scope.
