Ac Repair FAQ

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

Usually low refrigerant charge from an undetected leak, a dirty evaporator coil, or restricted airflow from a clogged filter.

Is ice on my AC unit a serious problem?+

Ice almost always means something is restricting airflow or refrigerant flow, and running it iced up can damage the compressor.

How much refrigerant does my system actually need?+

Every system has a manufacturer-specified charge amount — we don't top off blind, we charge to spec using superheat/subcooling readings.

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?+

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

How fast can someone reach Derby 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.
