Air Conditioning Installation & Repair in Chelmsford, MA
Looking for professional air conditioning installation & repair in Chelmsford, Massachusetts? Mass HVAC is the trusted local contractor for residential and commercial HVAC services in Chelmsford and throughout Middlesex County.
Chelmsford summers bring the kind of heat and humidity that makes air conditioning essential for comfort and health. MetroWest experiences the full range of New England weather, with winter temperatures regularly dropping below 10°F and summer humidity pushing heat indices above 100°F. A properly sized, well-maintained AC system is the difference between enduring summer and enjoying it.
Mass HVAC provides complete air conditioning services to Chelmsford and Middlesex County:
- New AC installation — including first-time central air for homes that have never had it
- System replacement — particularly for R-22 units that are now obsolete and expensive to service
- Repair for all brands — Carrier, Lennox, Trane, Rheem, Goodman, and more
- Cooling tune-ups — our pre-season inspection prevents breakdowns during peak heat
- Humidity control — whole-home dehumidifiers when AC alone is not enough
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.
