Air conditioning repair & service
Air Conditioning Repair in Whitehall, MT
Montana summers are short, hot and unforgiving on cooling equipment that sat idle all winter. We repair, charge and tune air conditioners so your system keeps up when the valley bakes.
Short season, hard use
Air conditioning in the Jefferson Valley works differently than in a long-summer climate. Your system may sit untouched from September to June, then get asked to hold a house at 72 while it's 93 outside and smoke has the windows shut tight. Equipment that has been idle nine months tends to reveal every weakness in that first week.
Capacitors that were marginal last August fail on the first hot day. Condenser coils collect a winter's worth of grass seed, cottonwood fluff and dust that acts like insulation and stops the unit from rejecting heat. Condensate drains plug with sediment and overflow onto a basement floor. Rodents nest in outdoor units and chew low-voltage wiring.
All of that is fixable, most of it inexpensively — if it's diagnosed correctly instead of treated as "needs more freon." Refrigerant doesn't get consumed; if a system is low, it's leaking, and finding that leak is the actual repair.
What a proper AC diagnosis includes
We check the easy things first — thermostat mode and setpoint, filter condition, breaker and disconnect, condenser fan operation — then move to measurement: suction and liquid pressures, superheat and subcooling, compressor and fan amp draw, capacitor microfarads, contactor condition, and the temperature split between return and supply air.
Those numbers tell a clear story. A low split with normal pressures points at airflow. Low suction with high superheat points at undercharge or a restriction. High head pressure with a hot condenser points at a dirty coil or a failing fan. Normal readings with poor comfort usually mean the duct system, not the equipment, is the bottleneck — a common finding in homes where cooling was added to a heating-only duct design.
Once we know, you get the repair options and prices in writing. If the compressor is grounded or the system is on obsolete refrigerant with a significant leak, we'll show you why a change-out is the better investment rather than quietly billing for a repair that won't last.
Annual AC service that prevents the emergency
A spring service visit is the cheapest cooling work you'll ever buy. We wash the condenser coil, verify the charge, test capacitors and contactors before they fail, clear and treat the condensate drain, lubricate and inspect motors, tighten electrical connections, check the blower and filter, and confirm the thermostat is controlling the system correctly.
The payoff is real: correct charge and a clean coil can cut cooling energy use noticeably, and catching a weak capacitor in May costs a fraction of an emergency call in July. Since we're already on site, we can check your heating equipment at the same time — see forced-air furnace service for what that covers.
And if your cooling problem turns out to be a blower or control issue on the heating side of the system, that's furnace repair territory — same visit, same technician, no second trip charge.
Local knowledge
Built for Whitehall and the Jefferson Valley
Cooling at 4,300 feet behaves differently than the textbook. Thinner air carries less heat per cubic foot, so airflow settings and charge verification matter more, and our wide day-to-night temperature swings mean a system sized for the hottest afternoon will short-cycle badly on a mild evening if it wasn't chosen carefully.
Late-summer smoke is the other local factor. When the valley fills in August, homes shut up tight and filtration takes a beating — and a restrictive filter installed for smoke can starve a blower that was already marginal. We help you balance filtration against airflow so you get cleaner air without freezing the coil.
We see the same patterns from Whitehall out to Cardwell, Three Forks and up toward Butte: older condensers running on borrowed time, and duct systems built for heat being asked to deliver cooling. Both are solvable once someone actually measures them.
Questions & answers
Frequently asked questions
Why is my air conditioner running but not cooling the house?+
The three usual causes are low refrigerant charge from a leak, a condenser that isn't rejecting heat because the coil is packed with cottonwood fluff and valley dust, or a failed capacitor leaving the compressor or outdoor fan not running. Restricted airflow from a plugged filter or dirty evaporator coil produces the same complaint. We measure pressures, superheat and temperature split to tell them apart rather than guessing.
My AC coil keeps freezing into a block of ice. What's wrong?+
Freezing means the evaporator is getting too cold for the air moving across it — nearly always low airflow or low refrigerant charge. Turn the system off and run the fan only to thaw it, replace the filter, then call us. Running a frozen system risks liquid refrigerant reaching the compressor, which is a far more expensive repair.
Is it worth repairing an older R-22 air conditioner?+
Sometimes. If the failure is electrical — capacitor, contactor, fan motor — a repair is usually the sensible choice. If the system has a refrigerant leak, R-22 is expensive and no longer produced, so putting several hundred dollars of gas into a leaking 18-year-old condenser rarely pays. We'll price both the repair and a change-out so the math is visible.
How often should air conditioning be serviced in Montana?+
Once a year, in spring before the first hot stretch. Our cooling season is short but intense, and equipment that sits idle nine months develops its own problems: seized fan bearings, rodent damage in the condenser, plugged condensate drains and weak capacitors that fail on the first 90-degree day.
Do you service AC in Butte, Cardwell and Three Forks too?+
Yes. We cover roughly a 50-mile radius from Whitehall, which includes Butte, Cardwell, Boulder, Three Forks, Twin Bridges, Silver Star, Harrison and Willow Creek. Same free consultation regardless of which side of the valley you're on.
Can you add air conditioning to a home that only has a furnace?+
In most cases yes. A forced-air furnace already provides the blower and duct distribution, so adding a matched condenser and evaporator coil is straightforward — provided the existing ductwork can carry the airflow cooling requires. We measure that first and include any duct corrections in the quote so the system performs as designed.
