About Belvidere AC & Heating
A Lowell heating and cooling company built on repeat customers and word-of-mouth referrals since 2005.
Our story
Belvidere AC & Heating has been serving homeowners and small businesses in Lowell, Massachusetts since 2005. The company was founded by Bobby Williamson and handles heating and air conditioning installation, repair and maintenance for all types of residential and light commercial properties. Whether it is a furnace that will not start, a central air unit that is blowing warm air, or a routine tune-up before the seasons change, the team works on most major brands and equipment types.
We have built the business on repeat customers and word-of-mouth referrals, and we take that seriously. A customer who calls us again for the next tune-up, or tells a neighbor about us, is the best measure we know of whether we did the job right.
Meet Bobby Williamson, Manager
Bobby has lived in the Lowell area his whole life and knows the local homes and weather inside and out. He got into heating and cooling work right out of high school, starting as an apprentice and learning the trade hands-on before eventually taking the lead at Belvidere AC & Heating.
Over the years he has built the business on straightforward values: show up on time, explain things clearly, and do the job right the first time. Customers working with Bobby can expect honest answers and no pressure to buy more than they need. He treats every house like it is his own, whether the job is a quick repair or a full system replacement.
Being local matters to him, and he is committed to keeping Belvidere AC & Heating a trusted name in Lowell for years to come.

Why local knowledge matters here
Heating and cooling in Lowell has its own habits. Many houses in the city's older neighborhoods were built around boilers and radiators long before anyone thought about air conditioning, and plenty of them have been converted from one fuel to another over the years. Triple-deckers put three households, often with three separate systems, under one roof. The surrounding towns add mid-century houses with ductwork, and newer homes built tight enough that ventilation matters. Winters bring single-digit nights and snow that buries vent pipes and outdoor units; summers bring humid weeks that expose every undersized or neglected air conditioner.
Someone who has lived and worked here all his life has seen those patterns many times over. It is why our questions on the phone tend to be specific, and why our recommendations take the house, not just the equipment, into account. Explore our services or see the towns we cover.
