Lennox Ac, Furnace & Heat Pump Service in Orange County
Lennox makes the highest-efficiency residential equipment on the US market - the SLP99V furnace and XC25 condenser still top the efficiency charts. The trade-off Orange County homeowners run into is parts: many Lennox components are distributed through Lennox-owned supply houses, so the wrong contractor will tell you a part is unavailable when it simply takes a day. We source Lennox parts and repair these systems rather than pushing you to replace.

Common Lennox Problems We Fix
What actually goes wrong with Lennox equipment in Orange County, and what the repair really involves.
iComfort communication errors
The S30 and E30 thermostats communicate with the equipment digitally. Comm faults are frequently a wiring or firmware issue rather than a failed board, and replacing the board first is an expensive guess.
Evaporator coil leaks on 2007-2012 units
Lennox evaporator coils from that era are a known leak point. If your system needs refrigerant every season, this is usually why.
Secondary heat exchanger on older SLP furnaces
Condensing furnaces move acidic condensate through the secondary exchanger. On high-run-hour units this is a wear item worth inspecting before winter.
Variable-speed blower motor modules
The ECM module fails more often than the motor itself, and the module alone is a far cheaper repair.
