A&G Heating & Air
Furnace Repair, Replacement & Tune-Ups in Merced
Merced's growth around the university has filled the city with a mix of older bungalows, family homes and rentals, all of which lean hard on their heating systems through the county's damp, foggy winters. A&G Heating & Air keeps those systems safe and efficient.
We work throughout Merced, from established neighborhoods near Bear Creek to newer developments on the north side and student rentals near the campus corridor. Rentals in particular need airflow and filter corrections along with the failed part, and we document everything for owners and managers.

Merced's fog and damp air contribute to pressure switch faults, condensate blockages and corroded flue components, alongside the usual igniter and flame sensor failures. We diagnose with combustion analysis and static pressure readings rather than guesswork.
If we find unsafe venting or a cracked heat exchanger we shut the system down, explain why and give you repair and replacement options the same visit.

Replacements are sized with a load calculation and matched to the ductwork we actually measure. Merced homeowners frequently choose heat pumps to cover both seasons efficiently, and we walk through the operating-cost math before you decide.
Every installation includes permits, code venting, freeze-safe condensate routing and commissioning. Learn more on our heating services page or add attic insulation through our energy services.
