AC Not Working Tonight? Here’s What to Do First.
Before calling run through this in 90 seconds. It resolves about 15% of after-hours calls without a service visit:
If you have a mini split
Check the remote. Mini split remotes accidentally switch to “Heat,” “Dry,” or “Fan” mode all of which move air without cooling it. Look for the snowflake symbol (❄) on the display. If it’s showing a sun or a water droplet, switch it to Cool mode and give it 10 minutes.
If you have central AC
Check the thermostat make sure it’s set to “Cool” and the temperature is below the current room temperature. Check the circuit breaker panel for a tripped breaker on the AC circuit reset it once. If it trips again immediately, do not reset it again. Call us.
Either system
Check the air filter. A completely clogged filter can shut a system down or cause the indoor coil to freeze over. If the filter is grey and packed solid, replace it and turn the system off for 2–3 hours before restarting.
If none of those fix it call (617) 928-8469 everything after that is our job.

The Most Common Emergency AC Calls We Get in Quincy
Mini Split Running but Not Cooling
Quincy has more ductless mini split systems than almost any market in Massachusetts because of its pre-war housing stock. If your mini split stops cooling during summer, the most common causes are a refrigerant leak, a clogged air filter restricting airflow, or a failed control board (PCB). Our technicians arrive with refrigerant and common replacement parts for Mitsubishi, Daikin, and Fujitsu systems to complete most repairs on the first visit.
AC Tripping the Circuit Breaker
A failing compressor, damaged wiring, or a weak capacitor can overload the electrical circuit and trip the breaker. Reset the breaker only once. If it trips again immediately, leave it off and call for service. Repeated resets can cause severe compressor damage and turn a simple repair into an expensive replacement.
Outdoor AC Unit Not Running
A worn contactor is the most common reason an outdoor condenser won’t start. The contactor supplies power to the compressor and condenser fan whenever the thermostat calls for cooling. These parts naturally wear out after years of operation, especially during Quincy’s humid summers. Most contactor replacements are completed in less than an hour.
Water Flooding from the Indoor Unit
A clogged condensate drain line prevents water from draining properly, causing leaks into walls, ceilings, or flooring. During humid summer weather, your AC removes several quarts of moisture every hour. We clear the blockage, flush the drain line, verify proper drainage, and inspect for any water damage before restoring the system.
System Iced Over or Completely Frozen
A frozen evaporator coil should never be ignored because continuing to run the system can permanently damage the compressor. Turn the thermostat off, switch the fan to On instead of Auto, allow the ice to melt, and schedule service. We identify whether the problem is caused by restricted airflow or low refrigerant and repair the root cause.

Emergency Call, Marina Bay Condo — 10:30pm, July
The situation:
A homeowner in the Marina Bay waterfront development called at 10:34pm on a Thursday in late July. Their Daikin 2-zone mini split system had been running all day but one zone the bedroom stopped producing cold air by evening. Outdoor temperature: 88°F. Indoor bedroom temperature: 84°F and climbing.
Before:
The technician arrived at 12:55am approximately 2 hours 20 minutes after the call. The bedroom zone’s indoor unit was blowing air but the refrigerant pressure on that circuit was critically low. The outdoor unit showed visible salt corrosion on the condenser fins Marina Bay’s waterfront location means year-round salt air exposure from Quincy Harbor. A pinhole leak at a brazed joint on the refrigerant line had been slowly bleeding the charge for an estimated two seasons.
What we did:
Recovered remaining refrigerant from the system, repaired the brazed joint, pressure-tested the full circuit for 45 minutes, recharged both zones to factory specification, and applied marine-grade coil coating to the condenser before leaving.
After:
Bedroom zone holding 71°F before the technician left at 3:20am. The homeowner had been running the system with a degrading charge for two summers without knowing it. The repair extended system life by an estimated 4–6 years.

Call (617) 928-8469 NowLandlord Emergency Tenant No Heat, Adams Shore Triple-Decker Sunday Night
The situation:
A landlord called at 8:15pm on a Sunday in August. A tenant in a second-floor unit of a triple-decker on Sea Street in Adams Shore reported the mini split had been blowing warm air all day. Outdoor temperature: 92°F. Tenant had a 4-month-old at home.
Before:
The Fujitsu 12,000 BTU single-zone unit had a solid amber fault light on the indoor head error code 07, which on Fujitsu systems indicates a communication error between the indoor and outdoor units. This is typically caused by a wiring fault or a failed outdoor control board. In this case the technician found a corroded connector on the communication wire at the outdoor unit salt air penetration at an unsealed conduit entry point.
What we did:
Cleaned and treated the corroded connector terminals, resealed the conduit entry with weatherproof sealant, cleared the fault code, and ran the system through a full test cycle. Communication between units restored. System producing 58°F supply air at completion.
After:
Unit cooling normally by 10:40pm — 2 hours 25 minutes from the landlord’s call. The landlord avoided a tenant complaint, a potential Massachusetts sanitary code violation for failure to provide habitable temperature conditions, and a 1-star review on their rental listing.
Total cost:

What Quincy Homeowners Say About Our Emergency Service
AC Not Working Tonight?
Don’t wait until morning. Call for emergency AC service in Quincy.
Call (617) 928-8469 NowDuring cooling season (May–September), our target response time is 2–4 hours from your call for anywhere in Quincy 02169, 02170, and 02171. We give you a real window when you call, not “sometime tonight.”
We answer. Not a voicemail system and not a national answering service. A real person who can dispatch a technician picks up. If for any reason you get a missed call in the middle of the night, text the same number. We monitor texts too.
The parts that resolve 80% of emergency calls, including capacitors, contactors, and common refrigerant needs, are always on the truck. For less common parts, such as specific control boards or indoor coil components for older units, we stabilize the system as much as possible the same night and return the next morning with the ordered part. We don’t leave you with nothing and a promise.
That depends entirely on your specific home warranty policy. We can’t answer that for you. What we can tell you is that we provide a written invoice with parts and labor itemized, which most home warranty companies require for reimbursement. Call your warranty company while we’re on the way because some require pre-authorization before work starts.
In most cases we fix it the same night. Capacitor swaps, contactor replacements, refrigerant recharges, and drain clears can happen in the same visit. We arrive with the tools and common parts for the repairs that cause the vast majority of emergency calls.
