Which season is it for?
Air conditioning is a summer problem with a spring solution. Lowell's summers are short but humid, and the first stretch of muggy weather in June and July asks systems that sat idle since September to run all day. Repairs, coil cleaning and new installations are easiest to schedule in April and May.
Heating is the bigger job around here. Merrimack Valley winters run from November into April, with single-digit nights in January and February. A furnace or boiler that is going to fail usually does it on the first cold night of the season, which is why we suggest heating tune-ups in September and October, and why replacements are best planned before the cold, not during it.
Heat pumps and mini-splits work both seasons, so they deserve a check before each one. Indoor air quality work, such as filtration, humidity control and ventilation, can be done any time of year.

Not sure what you need?
Describe what the system is doing. You will talk to someone who knows heating and cooling, not a call-center script, and we will point you to the right fix.
Which service do I need?
My house has radiators and no ductwork. Can I still get air conditioning?
Yes, but usually not central air in the classic sense, because central air needs ducts. The common answers in Lowell's radiator houses are ductless mini-splits in the main rooms, or a heat pump air handler in the attic that serves the top floor through short duct runs. Both leave the boiler and radiators in place for winter.
Should I repair my old air conditioner or replace it?
It depends on the age of the system, how often it has broken down, and which refrigerant it uses. Units that still run on R-22 are expensive to recharge because that refrigerant is no longer made. The AC page has a repair-or-replace table; we will tell you honestly which side of it you are on.
Is a heat pump the same thing as a mini-split?
Most mini-splits are heat pumps, but not every heat pump is a mini-split. A heat pump is any system that moves heat in or out of the house with refrigerant; it can feed ductwork like central air, or feed ductless heads on the wall. The heat pump page compares the options.
The heat works, but the house is dusty and dry all winter. Who do I call?
Us. Dust and dryness usually trace back to the system: leaky return ducts, a filter that does not fit, or forced-air heat without any humidity control. See indoor air quality.
Do I need a tune-up if nothing seems wrong?
A routine tune-up before the seasons change is how small problems, like a weak capacitor or a dirty flame sensor, get caught before they become a breakdown on the hottest or coldest day. The maintenance page explains what each tune-up covers.
Do you work on rental buildings and small businesses?
Yes. We handle residential and light commercial properties, from triple-deckers to storefronts and small offices. See light commercial HVAC.
