Air Conditioning Installation & Repair in Westford, MA

Air Conditioning Installation & Repair in Westford, Massachusetts

Westford 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.

Professional air conditioning service in Westford, MA starts with understanding the home. Middlesex County is characterized by colonial-era and mid-century homes, many built between 1950 and 1985, with basements, attached garages, and original HVAC systems that are nearing or past their expected lifespan. Each home type has different cooling requirements, and a system that works perfectly in one may be completely wrong for another.

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.

AC services we provide in Westford: - Central air conditioning installation and replacement - Emergency AC repair — we prioritize vulnerable residents during heat waves - Seasonal cooling system tune-ups - Refrigerant leak diagnosis and repair - Thermostat programming and smart home integration - Indoor humidity control and dehumidification

We never install an air conditioning system without first performing a cooling load calculation. This ensures your Westford home gets the right-sized unit — not too large (which short-cycles and fails to dehumidify) and not too small (which runs constantly and cannot keep up).
