Complete AC Repair Solutions

Everything Your AC Needs

Our air conditioning repair service covers everything from simple fixes like clogged filters and thermostat issues to complex problems like compressor failures and refrigerant leaks. We handle all major AC brands and system types common in Wellesley homes.

Each service call includes complete system diagnostics, not just fixing the immediate problem. This approach helps catch small issues before they become expensive emergencies. You’ll get honest recommendations about repairs versus replacement based on your system’s age and condition.

We stock quality replacement parts and use proper installation techniques that meet manufacturer specifications. Every repair comes with warranty coverage, and our Dempsey Comfort Club members get priority scheduling and additional savings on services.

Most AC repairs can be completed the same day we diagnose the problem. We stock common parts for all major brands and come prepared with diagnostic equipment to identify issues quickly. For emergency breakdowns during peak summer heat, we prioritize same-day service calls. Complex repairs requiring special-order parts might take 1-2 days, but we’ll give you a realistic timeline upfront and keep you updated throughout the process.
Repair costs depend on what’s actually wrong with your system. Simple fixes like replacing a capacitor or cleaning coils might run $150-300, while major component replacements can cost $500-1500. We always provide upfront pricing before starting any work, so you’ll know exactly what the repair costs with no surprise charges. Our diagnostic fee gets applied to the repair cost if you choose to move forward with our recommended fix.
If your AC is under 10 years old and the repair costs less than half of a new system, repair usually makes sense. For systems over 15 years old with major component failures, replacement often provides better long-term value. We’ll give you honest recommendations based on your system’s age, condition, and energy efficiency. Sometimes a repair can buy you another 2-3 years while you plan for eventual replacement on your timeline rather than during an emergency.
Yes, we provide emergency AC repair service, especially during peak summer months when system failures can create unsafe conditions. We prioritize emergency calls for customers with health concerns, young children, or elderly family members. Emergency service may include after-hours or weekend calls with appropriate service fees. Our goal is to restore your cooling as quickly as possible, even if it means a temporary fix followed by a permanent repair during regular hours.
We service all major AC brands including Carrier, Trane, Lennox, Rheem, Goodman, American Standard, and others commonly installed in Massachusetts homes. Our technicians stay current with training on different manufacturers’ systems and diagnostic procedures. We stock parts for the most common brands and can source components for older or less common systems. Regardless of your AC brand or age, we can diagnose the problem and provide repair options.
Regular maintenance prevents most AC breakdowns. Change your filter every 1-3 months depending on usage and filter type. Keep the outdoor unit clear of leaves, grass clippings, and debris that can block airflow. Schedule annual professional tune-ups to catch small problems before they cause system failures. Don’t ignore unusual noises, weak airflow, or higher energy bills – these often signal developing problems that are cheaper to fix early than after they cause a complete breakdown.
