Why Pittsburgh Homeowners Trust Shearer Heating, A/C & Refrigeration

Our technicians are NATE-certified, meaning they’ve passed independent, industry-recognized tests of heating system knowledge. We’re also a Carrier Factory Authorized Dealer, so our team receives factory training on the equipment we service. That combination matters when a furnace stops working in January. Every repair we complete is backed by a 3-year workmanship warranty and a 10-year manufacturer’s warranty, and our satisfaction guarantee means we don’t consider the job done until you’re comfortable with the result.

Our owners are accessible, and we treat every service call as the start of a long-term relationship, not a single transaction.

Common Furnace Problems We Fix

Pittsburgh winters are cold and damp. The moisture from the 3 rivers and the city’s temperature swings put real strain on forced-air heating systems. When something goes wrong, the signs are usually clear.

Furnace trouble signs that need professional attention:

• No heat or cold air blowing from registers despite the system running
• Banging, rattling, or screeching noises that signal loose or failing components
• Short cycling, where the furnace turns on and off repeatedly without completing a full heating cycle
• Ignition or pilot light failures that prevent the burner from lighting
• Blower motor issues that reduce or stop airflow entirely
• Uneven heating between rooms, or rising energy bills without a change in usage

A cracked heat exchanger is one of the most serious problems a furnace can develop. When it fails, carbon monoxide can escape into living spaces rather than venting safely outside. If you smell something unusual, notice odd system behavior, or your carbon monoxide detector activates, treat it as an emergency. Furnaces older than 12 to 15 years face a higher risk of this kind of failure.

Serving Pittsburgh’s Full Range of Homes

Pittsburgh’s housing stock presents genuinely different heating challenges. A century-old row house in Lawrenceville has different ductwork, insulation, and system constraints than a modern downtown condo or a newer build elsewhere in Allegheny County. Our technicians have worked across that full range and understand what each type of home demands from its heating system.

Hot, humid summers compound the problem by stressing equipment year-round. Heating systems that weren’t properly maintained through the warmer months often show the consequences when temperatures drop. That’s why we serve this area with both repair and maintenance capabilities.
