Before You Call: Ac Repair Answers

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

A full diagnostic checks all three before we touch the refrigerant charge.

Is ice on my AC unit a serious problem?+

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?+

Mini-splits have their own fault-code language, and our techs are trained on the major brands.

We prioritize no-cool calls with vulnerable occupants when scheduling.
