Complete AC Repair Solutions

Everything Your AC Needs Fixed

Our AC repair service covers the full range of issues that can shut down your system. Compressor problems, refrigerant leaks, electrical failures, frozen coils, fan motor issues, thermostat malfunctions, and ductwork problems all get handled by our experienced technicians.

Living in Cohasset means dealing with humid summers that put extra strain on AC systems. Salt air from the coast can accelerate corrosion on outdoor units. These local factors matter when diagnosing and repairing your system properly.

Every repair includes testing the entire system to catch potential problems before they leave you without cool air. You also get practical advice on maintenance that actually helps, like when to change filters and what warning signs to watch for. The goal is keeping your AC running reliably, not just fixing today’s problem.

How quickly can you fix my broken AC in Cohasset?

Most AC repairs in Cohasset get completed the same day you call, especially during summer months when we know you can’t wait around in a hot house. Simple issues like thermostat problems or clogged filters take under an hour. More complex repairs like compressor or refrigerant issues typically take 2-4 hours, depending on parts availability. We keep common replacement parts on our trucks, so most jobs don’t require return visits. If we need to order a specific part, we’ll let you know upfront and work with you on temporary solutions when possible.

What does AC repair typically cost in the Cohasset area?

AC repair costs depend entirely on what’s actually broken, which is why we always diagnose first before giving you a price. Minor repairs like replacing a capacitor or cleaning coils might run $150-300. Mid-range issues like fan motor replacement or refrigerant recharge typically cost $300-600. Major component failures like compressor replacement can run $1,200-2,500. We give you the exact cost upfront before starting any work, so you can decide if the repair makes sense or if replacement is a better option for your situation.

Do you service all types of air conditioning systems?

Yes, we work on central air systems, ductless mini-splits, heat pumps, and window units. This includes all major brands like Carrier, Trane, Lennox, Goodman, Rheem, and others commonly found in Cohasset homes. Whether your system is 2 years old or 20 years old, we can diagnose and repair it. Older systems sometimes need creative solutions when parts are discontinued, and we’re experienced at finding compatible replacements that keep your AC running reliably without forcing you into an unnecessary full replacement.

How do I know if my AC needs repair or replacement?

If your system is under 10 years old and the repair cost is less than half the price of replacement, repair usually makes sense. Systems over 15 years old with major component failures often cost more to keep fixing than replacing. Warning signs that point toward replacement include frequent breakdowns, dramatically higher electric bills, uneven cooling, and repair estimates over $1,500. We’ll give you honest advice about whether repair or replacement makes more financial sense for your specific situation, including how much life you can realistically expect from your current system.

What maintenance can prevent expensive AC repairs?

Changing your air filter every 1-3 months prevents most airflow problems that cause system strain and breakdowns. Keeping your outdoor unit clear of leaves, grass clippings, and debris helps it run efficiently. Annual professional tune-ups catch small problems before they become expensive failures. In Cohasset’s coastal environment, rinsing salt buildup off your outdoor unit a few times per summer helps prevent corrosion. Also, don’t ignore strange noises, weak airflow, or rooms that won’t cool properly—these early warning signs are much cheaper to fix than waiting until the system completely fails.

Do you offer emergency AC repair service?

Yes, we provide same-day emergency AC repair throughout Cohasset and surrounding Norfolk County areas. We understand that AC failures don’t wait for convenient times, especially during heat waves when your family’s comfort and safety are at stake. Emergency service is available seven days a week, and we prioritize calls from elderly customers, families with young children, and anyone with medical conditions affected by heat. While emergency calls may include after-hours fees, we’re upfront about all costs before dispatching a technician to your home.
