A&G Heating & Air
Furnace and Heat Pump Service in Porterville
Porterville sits where the valley meets the Sierra foothills, and that geography gives it colder mornings than most of Tulare County. A&G Heating & Air sizes and services Porterville heating systems for those extra cold hours, not for an average valley winter.
Homes east toward Springville and the lake see frost earlier and hold it longer than homes near Highway 65. We factor that exposure into equipment sizing and staging, which is why Porterville customers often end up with modulating or dual-fuel systems that run steadily instead of blasting and shutting off.

Longer runtimes wear Porterville equipment faster. We commonly replace blower motors, gas valves, igniters and control boards, and we frequently find undersized returns that have been quietly shortening equipment life for years.
Diagnostics include combustion analysis, gas pressure verification and CO testing. You get photos and a firm price before we proceed, any hour of the day.

Dual-fuel and cold-climate heat pumps make strong sense in Porterville, keeping efficiency on cold mornings while covering the long cooling season. For older homes without ducts, ductless mini splits heat individual rooms without a major retrofit.
We handle county permits, venting and full commissioning, and offer financing. Learn more on our heating services page or consider attic insulation through our energy services to cut runtime further.
