A&G Heating & Air
Furnace Repair, Installation & Heat Pump Service in Fresno
Fresno winters bring damp tule fog, overnight lows near freezing and heating systems that sit idle for eight months before they are asked to run every night. A&G Heating & Air keeps Fresno homes warm with fast heating repair, safe furnace installations and tune-ups scheduled before the first cold snap.
We dispatch from N Hayston Avenue, so technicians reach Woodward Park, Fig Garden, the Tower District, Sunnyside and Southwest Fresno quickly on cold mornings. Our trucks carry igniters, flame sensors, inducer motors, gas valves and thermostats for the furnace brands most common in Fresno tract homes and older bungalows. Every visit includes a combustion and safety check, photos of what we found and a written price in English or Spanish before work starts.

Most Fresno no-heat calls trace back to a handful of parts: a cracked hot surface igniter, a flame sensor coated in eight months of dust, a failed draft inducer or a thermostat that never got reprogrammed after summer. Because homes here run the furnace hard only a few weeks a year, small faults hide until the first 35-degree night, then show up all at once across the city.
Our technicians diagnose with combustion analyzers and static pressure readings rather than guesswork, so you learn whether the real problem is the part that failed or the duct restriction that killed it. If we find a cracked heat exchanger or unsafe venting in an older Fresno furnace, we shut the unit down, explain the finding and give you repair and replacement options the same day. Emergency heating repair in Central Valley homes is available around the clock.

Fresno housing runs from 1920s Tower District homes with retrofitted ductwork to newer Clovis-adjacent subdivisions with high-efficiency equipment. We size every replacement with a load calculation instead of copying the old nameplate, which matters in Fresno where oversized furnaces short-cycle through a mild winter and leave rooms uneven.
Many Fresno homeowners now pair furnace replacement with a heat pump so one system handles both the long cooling season and the short heating season, and we walk you through PG&E rates and available rebates before you decide. Financing is available, and our furnace installations in the Central Valley include permits, correct gas and venting work, and a walkthrough of the new controls.
