ABOUT THIS SERVICE

MINI-SPLIT REPAIR & DIAGNOSIS
FROM UTAH'S DUCTLESS EXPERTS

If your basement apartment lost cooling overnight or your ADU wall unit is blinking an error code and won't respond, you need techs who understand multi-zone systems and remote diagnostics — not a general HVAC crew guessing at a ductless system they've never trained on. They're efficient when working. When they fail, you need specialists.

We service all major brands: Mitsubishi, Daikin, Fujitsu, LG, Carrier, Lennox, and more. Common repairs: refrigerant leaks from line set damage, failed drain pumps, remote pairing issues, fan motor failures, dirty coils. Most repairs are same-visit. We carry parts on the truck.

Salt Lake County, Utah County, Davis County, Summit County, Wasatch County. 120-minute emergency response 24/7. Same-day appointments in most cases.

🔄
Multi-Zone System Inspection
One zone stopped cooling but the others work fine? A targeted inspection pinpoints whether the problem is a zone valve, control board, refrigerant line, or wiring fault. Skipping diagnosis and replacing parts at random wastes money. A full system health check covers all indoor heads, the outdoor unit, refrigerant balance across zones, and electrical connections. Most inspections complete in under two hours.

🌡️
Emergency Mini-Split Service
Mini-split failed overnight and your basement apartment is 85 degrees? We dispatch in 120 minutes across Salt Lake and Utah counties. Emergency service runs 24/7 including holidays. Common after-hours failures: drain overflow, refrigerant leaks from UV-damaged lines, compressor lockout from power surges. Same upfront pricing day or night. No surprise fees.

📋
Mini-Split Tune-Up
Annual maintenance prevents breakdowns. Keeps efficiency high. We clean indoor coils, flush drain lines, check refrigerant, test remote pairing, inspect outdoor connections. Mini-splits in basement apartments and ADUs run year-round. They need tune-ups twice as often as seasonal systems. Spring checkup catches problems before peak summer load.
Schedule Tune-Up →
💧
Refrigerant Leak Repair
Mini-split refrigerant leaks often happen where line sets run through walls or along exterior surfaces. Utah's intense UV damages exposed lines. Symptoms: reduced cooling, ice on the indoor coil, outdoor unit cycling off every few minutes. We locate leaks with electronic detectors. Repair or replace the damaged section. Vacuum the system. Recharge with the correct refrigerant. Most leaks are repairable without full line set replacement.

DO YOU NEED MINI-SPLIT SERVICE?

SIGNS YOUR MINI-SPLIT
NEEDS ATTENTION

🌡️
Wall Unit Not Responding
Remote won't pair? Wall unit beeps but won't blow air? One zone stopped cooling while others still work? Likely a remote failure, zone valve issue, or fan motor problem. Don't ignore it in summer.
Don't ignore this
💧
Water Leaking From Indoor Unit
Pooling water below the wall unit or dripping from the drain line? Likely a clogged drain, failed pump, or frozen coil from low refrigerant. Left alone, it causes mold and water damage.
Don't ignore this
⚡
Outdoor Unit Running But No Cooling
Outdoor condenser runs but delivers no cooling? Usually a refrigerant leak, failed zone valve, or disconnected wiring. These worsen fast. They spike your electric bill.

COMMON QUESTIONS

DUCTLESS MINI-SPLIT REPAIR & DIAGNOSIS
FREQUENTLY ASKED QUESTIONS

For mini-split emergencies across Salt Lake County, Utah County, and surrounding areas, the response commitment is 120 minutes. Real people answer 24/7. Not an answering service. We dispatch immediately. Most customers see us within the hour.

Mini-split repair pricing is quoted after diagnosis — system complexity, brand, and the specific failed component all affect cost. We provide a flat-rate quote before starting any work. No surprise fees.

All major mini-split brands are serviced: Mitsubishi, Daikin, Fujitsu, LG, Carrier, Lennox, Friedrich, Gree, and others. Our techs are trained on single-zone and multi-zone systems. We carry parts for the most common brands.

Water leaking from the wall unit? Usually a clogged drain line, failed pump, or frozen coil from low refrigerant. Utah’s hard water (150–300 ppm) clogs drain lines fast. We clear the line. Test the pump. Check refrigerant. Fixed permanently.

Most manufacturers provide a 5–10 year parts warranty and 1 year labor warranty on new installs. System still under warranty? We handle all claims and parts procurement. Our labor and diagnostic work is covered by a 1-year guarantee. This applies regardless of manufacturer warranty status. Spring is a smart time for a mini-split checkup — catching refrigerant or coil issues before peak cooling season saves money and avoids summer wait times.

Yes. $0 down financing with a 90% approval rate. Available on larger repairs and system replacements. A major repair shouldn’t blow your budget all at once. Ask your tech about financing when they provide your quote.
