Heating and Air Conditioning Service in Lowell, MA
Belvidere AC & Heating has been installing, repairing and maintaining heating and cooling systems for homeowners and small businesses in Lowell since 2005. Founded by Bobby Williamson, the company works on all types of residential and light commercial properties, and on most major brands and equipment types.
A furnace that will not start on a January morning, a central air unit blowing warm air in the middle of a July heat wave, or a routine tune-up before the seasons change: when you call, you talk to someone who actually knows HVAC systems, not a call-center script.
- An honest estimate, and no pushing repairs or replacements you do not need
- Technicians who show up on time and explain your system in plain language
- Appointments throughout the week; urgent no-heat and no-cooling calls fitted in as quickly as possible

Bobby Williamson, Manager
Bobby has lived in the Lowell area his whole life and got into heating and cooling work right out of high school, starting as an apprentice and learning the trade hands-on. He runs the company on straightforward values: show up on time, explain things clearly, and do the job right the first time.

Heating and cooling for Lowell's houses and weather
Lowell winters regularly bring nights in the single digits and nor'easters that pile snow against outdoor units and vent pipes. Summers swing the other way, with humid stretches in the upper 80s and 90s when a system that is low on refrigerant, or a condenser coil clogged with cottonwood fluff, stops keeping up. The houses vary just as much: triple-deckers and Victorian-era homes with steam or hot-water radiators in the city, and plenty of capes, ranches and colonials with ductwork in the surrounding towns. Each comes with its own heating and cooling habits.
- Radiator houses without ductwork usually get cooling from ductless mini-splits or an attic air handler, not from ducts cut through plaster walls.
- Oil heat is still common in older neighborhoods, and owners weighing a heat pump or a new furnace or boiler want a straight comparison, not a sales pitch.
- Houses with ducts can add central air or a ducted heat pump, as long as the ducts are sized for the airflow.
- Dry winter air, damp basements and dusty rooms are often fixable through the system you already have; see indoor air quality.
A Lowell maintenance year
- April–May: air conditioning tune-up before the humid weather
- June: rinse cottonwood fluff off the outdoor coil, with the power off
- September–October: heating tune-up before the first cold snap
- After every snowstorm: clear the vent pipes and the heat pump's outdoor unit
Common questions
How quickly can you come out when the heat or the air conditioning stops?
We offer appointments throughout the week and try to fit urgent heating and cooling problems in as quickly as possible, especially in the coldest and hottest weeks of the year, when every system in town is working its hardest. Call during business hours and describe what the system is doing. We will tell you honestly when we can be there.
Which towns do you cover?
We are based in Lowell and work in every Lowell neighborhood, plus the surrounding Middlesex County towns: Chelmsford, Dracut, Tewksbury, Billerica, Tyngsborough, Westford, Wilmington and others within a reasonable drive. The service area page has the full list and a ZIP code checker.
Do you work on my brand of furnace, boiler or air conditioner?
Most likely. We work on most major brands and equipment types: gas and oil furnaces, hot-water and steam boilers, central air conditioners, heat pumps and ductless mini-splits. If you can read the model number off the unit's label, have it handy when you call.
Will I know the price before the work starts?
Yes. We ask the right questions on the phone, look at the system, and give you an honest estimate before the work begins. If a repair makes more sense than a replacement, we say so, and we will not push repairs or replacements you do not need.
What does a seasonal tune-up involve?
Cleaning, testing and adjusting the system before the season it is about to work hardest in: the air conditioner in spring, the furnace or boiler in late summer or early fall. The maintenance page has both checklists and a month-by-month calendar for Lowell.
Smell gas? Leave the house first, then call your gas company or 911 from outside. Carbon monoxide alarm sounding? Get everyone outside and call 911.
