Commercial HVAC

Commercial HVAC in Hartford, CT
Rooftop Units, Repair & Replacement

Boisvert handles commercial HVAC repair and replacement for offices, stores, restaurants, apartment buildings and town facilities across Greater Hartford, from our shop on Peters Road in Bloomfield. Most of that work is on rooftop package units, along with ductless systems and furnaces in leased spaces. We hold Connecticut’s heating and cooling contractor license (S-1, HTG.0405214-S1).

What commercial HVAC work does Boisvert do?

Most commercial calls are about a rooftop package unit, the single cabinet on the roof that heats and cools a store or office. The usual problems are a unit that can’t keep up with the thermostat, water dripping through a ceiling because the condensate drain backed up on the roof, and a cracked heat exchanger. We also price and replace ductless split systems and fix no-heat calls in leased spaces, from small offices to town facilities.

Replacing a rooftop unit

A replacement unit usually goes onto the roof by crane, so the job is scheduled around the crane, roof access and a planned shutdown. For a tenant build-out, we price new or added units from your drawings, and a walk-through helps when existing equipment is staying.

Should you repair or replace a rooftop unit?

Replace a rooftop unit when the repair would cost about half the price of a new one, or when an older R-22 unit has a refrigerant leak. Most owners decide with both prices in hand, and we can quote both: one to replace the failed part, such as a heat exchanger, and one to replace the whole unit.

R-22 is the refrigerant in many older units, and it hasn’t been produced or imported in the US since 2020. That’s why a leak on an R-22 unit usually points to replacement rather than another recharge.

What to have ready when you call:

  • The unit number, and a photo of its model and serial tag

  • Who can open the roof hatch or bring the building’s lift

  • Drawings or a scope of work, for a build-out

  • Who is paying, and whether you need a credit application on file

REQUEST ESTIMATE

How does commercial HVAC service work?

Call the office and we’ll book a visit with an arrival window, often for the next morning. The first appointment of the day arrives between 8 and 9 AM. If the technician needs roof access, say so when you book, and ask them to call when they’re on site so building maintenance can let them up. Service is paid at the time of the visit by card or check, and each visit carries a standard service charge, quoted when you book. If your company needs a purchase order or invoice terms, ask for a credit application before the first visit.

Tenants, landlords and property managers

In a leased space, the person who calls isn’t always the person who pays. We send a technician once whoever is responsible for the bill has approved the call, which is often the landlord or the management company, not the tenant. Give us an on-site contact and the unit’s location when you book. Several of our commercial customers are property managers who call us for more than one building.

After hours

Office hours are Monday to Friday, 8 AM to 5 PM. Emergency service is available 24/7: after hours, call the same number and press 1 to reach our on-call staff. After-hours visits are billed at overtime rates. For boilers and hot water systems, see commercial boilers. For gas lines to rooftop equipment, see commercial gas piping.
