Air Conditioning Installation & Repair in Littleton, MA
Looking for professional air conditioning installation & repair in Littleton, Massachusetts? Mass HVAC is the trusted local contractor for residential and commercial HVAC services in Littleton and throughout Middlesex County.
Littleton 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 Littleton 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.

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.
Yes. Mass HVAC holds a Massachusetts HVAC contractor license, EPA Section 608 refrigerant certification, and a Massachusetts Construction Supervisor license, and carries full general liability and workers' comp insurance. All cooling work in Littleton is performed by licensed technicians and pulled with the correct local permits.
