Detailed pages for the work we're asked about most.

AC Repair

When an air conditioner quits during an Orange County heat wave, the question isn't whether it can be fixed — it's how fast someone can get there and how honest they'll be about what it needs. HG Heating & Air is a family-owned, licensed C-20 contractor, and AC repair is what we're called for most.

AC Installation

A new air conditioner is only as good as the installation behind it. Equipment that's oversized, undersized or connected to undersized ductwork will short-cycle, run loud and never reach the efficiency printed on the label. We size the system to the house, not to a rule of thumb.

Heating Repair

Southern California heating systems spend most of the year switched off, which is exactly why they fail on the first cold night. This page covers heating repair across every system type we service — heat pumps, wall and floor heaters, and central systems. If you specifically have a gas furnace, the furnace repair page goes into the parts and symptoms unique to it.

See details

Furnace Repair

A gas furnace is a sequence of safety interlocks wrapped around a burner. When one link in that sequence stops proving itself, the furnace refuses to light — which is the system working correctly, not failing randomly. Reading that sequence is how we find the actual fault instead of replacing parts and hoping.

Mobile Home HVAC

Manufactured homes don't take standard residential HVAC equipment, and that catches a lot of homeowners — and a lot of contractors — off guard. Mobile home heating and cooling is one of our specialties, and we keep the equipment and parts these systems actually take.
