AC Maintenance in Whitehall, MT

Wash the condenser coil, clear debris from the cabinet, check the fan blade and motor bearings, test the capacitor against its rating, inspect the contactor for pitting, measure compressor amp draw, verify charge with superheat and subcooling, clean or treat the condensate drain, check the float switch, and measure temperature split and static pressure indoors.

Everything gets written down. A charge that reads slightly low two springs in a row means a leak, and that is only visible if last year's numbers exist.

A condenser coil coated in valley dust and smoke residue cannot reject heat. Pressures climb, capacity falls, the compressor works harder, and your power bill absorbs the difference — all while the unit still appears to be cooling.

The other payoff is failure prevention. Capacitors and contactors are cheap parts that age during the nine months the system sits idle. Replacing a weak one in May costs a fraction of an emergency call in July, and it protects the compressor from starting against a weak capacitor.

April through early June is ideal — after the heating season and before the first hot spell. Many homeowners pair it with heating maintenance in the fall so one visit covers the furnace and the next covers cooling.

If the season is already underway, a tune-up still helps. We simply schedule around active no-cooling calls, which take priority during a heat stretch.
