Furnace Repair, Replacement & Maintenance in Coalinga
Coalinga winters are short, but clear desert-style nights can drop near freezing, and a furnace that sat idle all summer often struggles on that first cold evening. A&G Heating & Air repairs, maintains and replaces heating systems throughout Coalinga.
Because Coalinga furnaces run only a few months a year, dust buildup, dirty flame sensors and worn igniters are the most common causes of no-heat calls. We clean, test and verify safe combustion so your system starts reliably when temperatures fall.

We diagnose ignition failures, blower problems, limit switch trips and short cycling with proper testing, not guesswork. Every repair visit includes a carbon monoxide and combustion safety check.
You receive a clear explanation of the problem and a written price before we begin, with emergency heating service available any hour.

When a furnace is near the end of its life, we size a replacement with a load calculation and check ductwork so the new system heats evenly. Many Coalinga homeowners also consider heat pumps, which provide both heating and cooling in one system.
We compare gas and electric options honestly, handle permits and explain available financing.
