Commercial Heating Services

Furnaces, boilers, and heat pump systems for commercial properties.

Heating systems in commercial buildings

Commercial heating equipment ranges from gas furnaces paired with rooftop package units to boilers serving multifamily buildings and heat pump systems used in offices and retail spaces. Each system heats a building differently, and a boiler problem in a multifamily property, where the equipment may be feeding radiant heat or hot water to multiple units, is diagnosed differently than a single rooftop furnace serving one retail space. A technician confirms the system type and how it is zoned across the building before narrowing down the cause of a heating complaint.

Typical commercial heating calls include a furnace that will not ignite, a boiler losing pressure or cycling incorrectly, uneven heating across zones, or a heat pump that is not switching properly between heating and cooling modes. A $120 diagnostic fee applies to repair visits and is waived once you decide to move forward with the repair, with the repair price provided in writing before work begins.

Coordinating repairs with property operations

Heating failures in a commercial building are rarely convenient, especially for multifamily properties where residents depend on the system or offices with occupied workspace. The property manager or facility staff should identify equipment access and any shared controls. A complaint affecting one zone can point to a valve or thermostat rather than the central heat source. Those distinctions help separate a distribution problem from equipment that will not start.

For equipment replacement, such as swapping an aging boiler or replacing a rooftop furnace unit, a free written estimate is prepared based on the specific equipment and access conditions at the property. The scope of the job, including any ductwork or piping changes needed, is reviewed before any work begins.

Financing for equipment replacement

Boiler and furnace replacement can represent a substantial cost, particularly for properties with multiple units or zones. Financing is available through home service lenders, including 0% promotional plans for qualifying, approved credit. Applications take a few minutes to complete, most decisions come back instantly, and the work is scheduled once financing is approved. Contact the Tempe shop at 1917 E 5th St to discuss a heating issue at a commercial property or to request a replacement estimate.

Keep service invoices alongside model and serial numbers. Records of recurring ignition trouble or pressure loss give the facility team something specific to compare at the next visit.
