Looking for professional air conditioning installation & repair in Westborough, Massachusetts? Mass HVAC is the trusted local contractor for residential and commercial HVAC services in Westborough and throughout Worcester County.
A surprising number of MetroWest homes were built without central air conditioning. Rather than retrofitting ductwork through finished walls, many homeowners are choosing ductless mini-split systems that provide both heating and cooling from a single unit — with no major construction required.
For Westborough 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 Westborough is sized using Manual J calculations to match your home's exact cooling load.

Sizing is done with a Manual J load calculation — typically 1 ton of AC per 600–800 sq ft of conditioned space, adjusted for insulation, window area, and orientation. We never quote an AC by square footage alone; oversized units short-cycle and fail to dehumidify, undersized units never reach setpoint. Free in-home sizing is part of every estimate.
