We offer same-day AC repair service in Green Harbor for most emergency calls, especially during heat waves when you need cooling restored immediately. Our technicians carry common parts and diagnostic equipment to complete most repairs during the first visit. If we need to order a specialized part, we will often offer a temporary solution to keep you cool while waiting for the permanent fix. Emergency calls get priority scheduling because we know how uncomfortable and potentially dangerous a house without air conditioning can become during Massachusetts summers.
We handle every type of AC repair, from simple issues like blown fuses and dirty filters to complicated problems like compressor failures and refrigerant leaks. Common repairs include replacing capacitors, cleaning evaporator coils, mending electrical connections, repairing ductwork leaks, and addressing thermostat malfunctions. Our technicians are trained on all major air conditioning brands and carry diagnostic equipment to quickly identify problems. If your system will not turn on, is not cooling properly, or is making strange noises, we can diagnose and fix the issue quickly.
Yes, our technicians are well-versed with all major air conditioning brands, including Carrier, Trane, Lennox, Rheem, Goodman, York, and many others. We stock common parts for most brands and can usually source special components quickly when needed. Our diagnostic approach focuses on the problem rather than the brand, so we can effectively troubleshoot and repair any system. We also service both central air systems and ductless mini-split units, regardless of age or manufacturer.
First, check your thermostat settings and make sure your circuit breaker has not tripped. Look at your air filter—if it is completely clogged, replace it and see if that helps. If these basic steps do not solve the problem, call us immediately rather than trying to diagnose further. Attempting DIY repairs on AC systems can be dangerous and often makes the problem worse. We will walk you through any safe troubleshooting steps over the phone and get a technician to your Green Harbor home as quickly as possible to restore your cooling.
Regular maintenance is the best way to stop AC breakdowns. Change your air filter monthly during peak usage, keep the outdoor unit clear of debris and vegetation, and schedule annual tune-ups before the cooling season begins. Our Dempsey Comfort Club members get maintenance reminders and priority service to catch small problems before they become expensive repairs. In Green Harbor’s coastal environment, we also suggest more frequent coil cleaning to stop salt corrosion and humidity-related issues that can cause premature system failures.
Every service call includes a complete system diagnosis using professional testing equipment, a clear explanation of what is wrong and what it will cost to fix, and upfront pricing with no hidden fees. If you approve the repair, we complete the work and test the system to confirm it is running properly. We clean up our work area and give you information about what was repaired and any maintenance recommendations. Our technicians also check related components to catch potential issues early, and we follow up to make sure you are satisfied with the repair.
