AC stopped working? We’ll aim for same-day repair
If the system quits on a warm afternoon, we aim to place you the same day whenever you call early. We text an ETA, arrive within the window, and begin with quick checks that cut to the root cause without guesswork.
After-hours emergencies are covered too, because a sticky night off Route 16 is nobody’s idea of rest. We bring common parts, test instruments, and drain cleaning tools so most fixes happen on the first visit.
Common emergency AC problems we fix
Warm air
Warm supply air often traces back to low refrigerant, a failed condenser fan capacitor, or a clogged filter choking airflow. We confirm charge, verify the outdoor fan, and balance the thermostat settings so cooling stabilizes.
Short cycling
Rapid starting and stopping can come from restricted airflow, an iced evaporator, or equipment that’s oversized for the home. We measure static pressure, inspect controls, and look for safeties that are tripping before components get stressed.
Frozen coil
A frosted indoor coil usually means poor airflow or a low charge. We safely thaw the coil, correct the airflow path, and set refrigerant to spec so the evaporator stays clear during humid spells.
Water around the air handler
Puddles near the indoor unit are common when the condensate line is clogged or the pan is cracked. On muggy evenings near Hopedale Pond, heavy condensation can overwhelm a dirty drain; we clear the line, treat the pan, and recheck slope so it keeps flowing.
Breaker trips
If the breaker pops the moment the condenser tries to start, a weak capacitor, shorted wire, or tight compressor is often to blame. We test under load, replace only what’s needed, and confirm amperage stays in range.
How we repair air conditioning units
- Identifying the issue: We’ll review the thermostat program, and take a quick look at both the indoor and outdoor units before we make a final assessment.
- Safety and power. We verify disconnects, breakers, and wiring, then check contactor, capacitor, and fuses for visible failures.
- Airflow and refrigeration. We measure temperature split, superheat, and subcool while checking filters, blower operation, and coil condition.
- Fault isolation. We test compressor and fan amps, sensors, and control boards, and clear the condensate drain if it’s restricted.
- Options and approval. You see findings, repair choices, and timelines, along with what drives cost such as parts availability, refrigerant type, and overall system health.
- Repair and verification. We install parts, set charge, run a complete system test, tidy the work area, and leave simple care tips.
Emergency & same-day availability
We’re open Mon–Sat 7am–7pm with true emergency dispatch after hours. Same-day slots fill fast, and calling before 2 pm gives you the best shot at an afternoon visit.
We work a 25-mile radius across Worcester County along Route 16 and Freedom Street, so Hopedale, Milford, Mendon, Upton, and Uxbridge are all within easy reach.

Air conditioning brands we service
We work on Carrier, Trane, Lennox, Goodman, Rheem, Ruud, York, Bryant, American Standard, Payne, Heil, Amana, Day & Night, and most modern systems. Ductless and heat pump lines such as Mitsubishi Electric, Daikin, LG, and Fujitsu are fully supported.
Service area
Based near Hopedale and serving Milford, Mendon, Upton, Bellingham, and Uxbridge. If you’re in Worcester County or just outside the radius, call and we’ll let you know the soonest window.
Maintenance to prevent the next breakdown
Regular tune-ups keep coils clean, drains clear, and electrical parts within spec. That prevents nuisance shutdowns, improves dehumidification, and helps the system ride through August heat.
If you’d rather not track the upkeep, our Maintenance plans cover seasonal visits and priority scheduling. We check charge, wash the condenser, test capacitors and blower performance, and verify airflow so comfort stays consistent.
FAQs
On typical days we can schedule a same-day diagnostic, especially if you call before early afternoon. During heat waves we open extended hours so urgent calls don’t wait through the weekend.
We handle most major manufacturers along with heat pumps and ductless mini-splits. If the system is nearing the end of its life, we can also quote AC installation and make sure the new equipment is sized and commissioned correctly.
R-22 is phased out and harder to support. We’ll locate any leak, go over repair paths, and compare them with replacement so you can decide with full information. All refrigerant handling is performed by EPA Section 608–certified technicians for safety and compliance.
We look at age, repair history, compressor condition, energy use, and parts availability. If a major component is failing on an older unit, replacement can be the smarter spend; if the issue is a capacitor, contactor, or a blocked drain, a repair usually makes sense. We also take care of Heat pump repair if you’re thinking about a future switch.
