Working in Saint John
Salt air corrodes outdoor coils and cabinets, and damp weather calls for good humidity control indoors. Ask about coastal coil protection, where the outdoor unit will sit out of drifting snow and spray, and how the system handles mild, wet winters.
New Brunswick's economy is anchored by forestry, IT services in Fredericton-Moncton, and Saint John's deep-water port, with humid-continental winters and short, mild summers.

Questions
Do you take hvac replacement and installation jobs in Saint John?
Yes. Requests from Saint John, Fredericton, Moncton, Laval and the rest of New Brunswick are handled the same way. Use the quote form on this page, or email [email protected] with the service, the address and the timing.
How long does installation take?
A straightforward residential furnace or AC replacement is often a one-day job. Switching to a heat pump, adding ductwork or upgrading electrical can add time. Commercial rooftop replacements depend on crane scheduling, curb adapters and building access, and are planned around your operating hours.
Do you work on commercial rooftop units?
Yes. We scope RTU replacements and service for retail, office, light industrial and multi-unit buildings, including curb adapters, crane lifts, controls and planned shutdown windows so tenants are disrupted as little as possible.
Do you still clean commercial kitchen exhaust systems?
Yes. Kitchen exhaust and hood cleaning remains one of our services: hoods, filters, ductwork and rooftop exhaust fans, cleaned to the NFPA 96 standard with before and after photos.
Should I repair my system or replace it?
It depends on the age of the equipment, what failed and how the repair compares to the value left in the system. A cracked heat exchanger, a failed compressor on an older unit, or repeated breakdowns in the same season usually point toward replacement. A failed igniter or capacitor usually does not. We will tell you which side of the line you are on.
Heat pump or furnace: which makes sense where I live?
Cold-climate heat pumps now run well into deep winter temperatures, but the right answer depends on your electricity and gas rates, your ductwork, your electrical panel and how cold your area gets. Many homes in colder regions pair a heat pump with a gas furnace as backup. We lay out both options so you can compare.
