Commercial HVAC Repair in Buffalo, NY

We take repair calls on equipment owned by small operators. That usually means a rooftop package unit, a split system or a gas furnace serving one space, or the furnaces and boilers in a double or small multi-unit building you own.

Give us the address, the equipment and the fault. If the job involves a chiller, a building automation system or a large roof installation, we say whether we take it on. We promise no arrival window, and we tell you honestly when we can get there.

If you lease space and the landlord owns the roof unit, tell us who can approve a quote, so a tenant’s call does not stall while the owner is reached.

What symptoms should you report when you call?

• No heat or no cooling: note whether one tenant space or the whole building is affected, since that points to the unit, the controls or the power.
• Uneven temperatures: one room cold while another runs warm, often a damper, thermostat or airflow fault.
• Short cycling: the equipment starts, runs briefly and stops, which wears out parts quickly.
• Tripped breakers or a blank thermostat: write down which breaker and how often it trips.
• Ice, water or odor: ice on a coil, water at a ceiling tile, or a burning smell from a blower.

Buffalo averages about 6,466 heating degree days a year, according to NOAA’s 1991-2020 normals. Heating equipment here runs for months, and a unit on a roof also takes drifting snow, ice on the coil section and swings across freezing.

Leased space adds a people problem. When the landlord assumes the tenant changes the filter and the tenant assumes the landlord does, nobody does. Older buildings add mixed equipment from different decades, so one failure rarely looks like the next.

1. 1Listen first. When it stopped, what changed, and who has worked on it. A tenant’s complaint often holds the clue.
2. 2Check power and controls. Breaker, disconnect, thermostat or controller, and safety switches come first because they are quick to rule out.
3. 3Test the equipment. We meter the capacitor, contactor and motors, and check ignition on gas heat, instead of guessing.
4. 4Check airflow. Filters, blower, belts and coils. A starved coil causes many calls.
5. 5Read the system. Pressures, temperatures or gas-side readings tell us whether the problem is a part or something bigger.
6. 6Show you and quote it. You see the fault, hear the options and decide. Nothing is replaced without your approval.

We say so when a repair is not worth making. Customers have told us we fixed equipment another company wanted to replace. When a rooftop unit is near the end of its life, our rooftop unit service page explains how we weigh it.

Age matters as much as the part. The U.S. Department of Energy says rooftop units typically last 15 to 20 years, though some fail earlier and units in corrosive settings can wear out nearer 10. A unit in that age range with a major failure is a replacement conversation. A cheap electrical part on a younger unit is not.

Many repairs finish on the first visit when the part is common. A specialty part, an iced roof or a coil that must thaw means a second trip. Our hours are Monday through Friday, 7:30 to 5, so a Friday-afternoon failure may not be fixed before the weekend, and we tell you that on the call.

We publish no price list, because the cost depends on the part, the age of the unit, the refrigerant or fuel it uses and how hard it is to reach. In the City of Buffalo, heating work goes through Permit & Inspection Services, and work started before a permit is issued can be charged double fees under Buffalo Code Chapter 175. New York has no statewide HVAC license, so confirm your municipality’s rules.

Five variables move a commercial repair quote. The first is whether the part is a stock item or must be ordered. The second is how the roof is reached, and whether snow or ice must be cleared first. The third is the unit’s age and whether its parts are still made. The fourth is the refrigerant it uses. The fifth is whether the fault is one part or a chain of them. Ask about any diagnostic fee when you call, since we publish no price list.

Which local rules apply to repairs on a commercial building?

Erie County Consumer Protection says New York has no statewide HVAC contractor license, so the rule that applies depends on the municipality. The City of Buffalo requires a Heating Contractor license for heating work, and the Fuel Devices office in Permit & Inspection Services can confirm what a job needs. Cheektowaga licenses HVAC contractors, and the Town and City of Tonawanda and the Village of Kenmore require contractor licensing. Confirm with the municipality that covers your address, and ask any company you hire, us included, which license and permit apply before work starts. Refrigerant is separate. The EPA requires technician certification under Section 608 of the Clean Air Act, and its leak-repair rules for larger appliances began January 1, 2026, so ask which, if any, covers your unit.

• Assign one person to change filters on a schedule, and log the date.
• Keep snow, leaves and debris away from intakes, condensers and flue terminations.
• Photograph each unit’s nameplate so model and serial numbers are on hand.
• Book commercial HVAC maintenance before the heating and cooling seasons start.
