Air Conditioning Installation & Repair in Lexington, Massachusetts
Lexington residents trust Mass HVAC for professional air conditioning installation & repair. Serving Middlesex County and the surrounding communities, we bring decades of combined experience to every heating, cooling, and air quality project.
Space is at a premium in Greater Boston. Ductless mini-splits are the preferred cooling solution because they require no ductwork, the indoor units are compact and wall-mounted, and the outdoor condensers can be bracket-mounted to save ground space. We also work within condo association guidelines to ensure installations comply with building rules.
For Lexington homeowners, our AC services include:
- Central AC installation — new systems for homes with or without existing ductwork
- AC system replacement — upgrade from R-22 to modern R-410A refrigerant systems
- Emergency AC repair — same-day service when possible, especially during heat waves
- Seasonal tune-ups — our cooling inspection keeps your system running efficiently all summer
- Smart thermostat installation — optimize cooling schedules for maximum efficiency
- Ductless mini-split cooling — ideal for rooms that central AC cannot reach
We carry a full line of high-efficiency air conditioning systems from brands including Carrier, Lennox, Trane, and Daikin. Every AC installation in Lexington is sized using Manual J calculations to match your home's exact cooling load.
