An outside unit that hums while the fan stays still is the call we get most in July in Pocatello, ID, and the cause is usually a failed run capacitor. That inexpensive component starts the compressor and fan, fades for years without complaint, and then quits under peak load. It is far from the only suspect, though. Contactors pit and stop passing clean power, condenser fan bearings dry out, small refrigerant leaks drain away cooling capacity, and evaporator coils ice over when a clogged filter strangles airflow.
Warm air from the vents can mean a failed capacitor, a refrigerant leak, a frozen coil, or a duct problem, and each one comes with a very different price to fix. That is why Pocatello HVAC tests before touching anything. We meter capacitors against their microfarad rating, compare compressor and fan amp draws to the data plate, judge the refrigerant charge by superheat and subcooling instead of pressure alone, and inspect the coil, blower wheel, and filter whenever there is ice. Topping off refrigerant without locating the leak only buys cold air until the charge leaks out again.
Straight answers are part of every visit. If an aging system's compressor has failed, we explain the repair-versus-replacement math plainly and let you decide. Most of the time, though, the fix is simpler, and because our trucks stock capacitors, contactors, fan motors, hard-start kits, and condensate pumps, the house is usually cooling again before we leave. We work on central air, heat pumps, and ductless mini splits from all major brands. Need AC repair in Pocatello? Call (208) 208-1923 and an experienced technician will be on the way.

How Much Does AC Repair Cost in Pocatello?
Most air conditioner repairs in Pocatello land between $150 and $650. Small electrical parts like capacitors and contactors sit at the low end, while refrigerant leaks, coils, and compressors cost more. Every repair starts with a diagnosis and a clear, upfront price.
| Repair | Typical cost | What it usually means |
|---|---|---|
| Capacitor replacementThe most common AC failure; outdoor unit hums but won't start | $150–$400 | Most common repair, usually same visit |
| Contactor replacementBurned or pitted switch that powers the outdoor unit | $150–$350 | Worn relay that stops the condenser from starting |
| Condenser fan motorFan won't spin, unit overheats and shuts down | $300–$700 | Fan won't spin, unit overheats and shuts down |
| Refrigerant leak repair + rechargeDepends on leak location and refrigerant type | $300–$1,500 | Varies with where the leak is and how much charge is lost |
| Evaporator coil replacementMajor repair; worth weighing against replacement on older systems | $1,000–$2,500 | Corroded or leaking indoor coil |
| Compressor replacementOn systems past 10–12 years, replacement usually makes more sense | $1,500–$3,000 | On systems past 10–12 years, replacement usually makes more sense |
Typical ranges for common repairs. Your exact price is quoted after diagnosis.
What Moves the Cost Up or Down
- The age of the system and whether parts are still readily available
- Refrigerant type, because R-22 recharges are much more expensive
- Timing, such as same-day or after-hours service versus a scheduled visit
- Access to the equipment, like rooftop units or tight attic air handlers
On older systems we always compare the repair against a replacement, so you can make the call with real numbers. Questions about cost? Call (208) 208-1923.
Warning Signs for AC Repair
Spotting the early warning signs gives you the chance to act before the situation spirals into something far more expensive. These are the signals our technicians see most often when a problem is underway:
- Water dripping from the indoor unit or showing up on the ceiling below
- Ice on the refrigerant lines or a frozen indoor coil
- Rapid on-off cycling that never brings the temperature down
- Room-temperature air from the registers even though the AC is running
- Bubbling or hissing noises that point to a possible refrigerant leak
- Cooling bills climbing while the house stays sticky and warm
- A condenser fan that sits still while the outdoor unit hums
- Breaker trips or a burning odor at startup
Early Action Saves Money
Left unchecked, even a small fault or temperature swing often signals a system working its way toward a breakdown. Call Pocatello HVAC at (208) 208-1923 at the first sign of trouble.
AC Repair FAQ
Why Hire a Professional for AC Repair?
An air conditioner puts several hazards into one cabinet. The capacitor can deliver a painful shock long after the breaker is off, the condensing unit is wired for 240 volts, and the refrigerant circuit is a sealed, pressurized loop that federal rules forbid venting. Servicing it properly takes gauges, a recovery machine, and a vacuum pump, not a DIY recharge can. Diagnosis has its own traps. A frozen coil is as likely to be an airflow issue as a charge issue, and recharging a system that still leaks throws money away while moisture and acid work on the compressor.
Professional repair gets the whole picture. Our experienced technicians meter electrical components instead of swapping them, weigh charge decisions against measured superheat and subcooling, find leaks with detectors and dye rather than assumptions, and check the filter, blower, and duct static pressure whenever airflow is suspect. That is the difference between a repair that holds through the season and a parts-cannon fix that calls you back in three weeks. And when the system genuinely is not worth saving, we tell you that plainly too, with numbers instead of pressure.
Our AC Repair Process
Our systematic workflow delivers thorough, lasting results on every job. Here's what you can expect when you choose Pocatello HVAC:
Full Cooling Diagnosis
Capacitors, the contactor, motors, and amp draws are all measured, the charge is checked through superheat and subcooling, and the coil, filter, and drain are inspected so the real failure is found.
Clear Explanation & Price
Nothing happens without your approval. We explain what broke and why, quote a firm price, and, if the compressor or coil has failed, walk you through repair versus replacement honestly.
Repair From a Stocked Truck
Most AC fixes happen right away. We carry capacitors, contactors, fan motors, and other high-failure parts, so you are rarely left waiting on a parts order.
Performance Verification
The repair is proven, not assumed. We watch a full cooling cycle, confirm the temperature drop across the coil, verify amp draws and charge, and make sure the condensate line is draining freely.

Call (208) 208-1923 TodayMaintenance Tips for AC Repair
A few simple habits now, like regular filter changes and seasonal tune-ups, can add years to your system's life. Put these technician-approved steps to work around your property:
- Replace the filter every month in summer, since restricted airflow is the top cause of frozen coils
- Rinse the outdoor condenser coil each spring and keep vegetation two feet back
- Clear the condensate drain when you first turn on the AC each year
- Keep supply and return vents open; closing rooms raises static pressure on the blower
- Listen for new buzzing or clicking at startup, the classic sound of a dying capacitor
- Shade is fine, but do not box in the outdoor unit with fences or covers
- Book a professional tune-up each spring before the first heat wave finds the weak parts
DIY vs. Professional AC Repair
Some simple checks are suitable for DIY, but most heating and cooling repairs benefit from professional tools, training, and experience. Consider the following comparison:
| Factor | DIY Attempt | Professional Service |
|---|---|---|
| Refrigerant Leaks | Top-offs without finding the leak | Leak located, repaired, charge weighed in |
| Shock Risk | Stored capacitor charge and live 240V | Capacitors drained, power confirmed off |
| Iced Coils | Defrost it and hope for the best | Airflow or charge problem identified and fixed |
| Diagnosis | Guessing between look-alike faults | Instrument readings, not hunches |
| Replacement Parts | Whatever capacitor or motor fits | Specs matched to the equipment data plate |
| Outcome | Short-lived relief | Tested and confirmed under load |
