Ac Repair FAQ

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?+

Yes, though R-22 supply is limited and increasingly expensive — we'll be upfront if a repair-versus-replace conversation makes more financial sense.

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.

How fast can someone reach Union during peak summer demand?+

Call volume rises with the heat, so arrival windows can extend during heat waves — dispatch gives you a live estimate when you call.
