Lennox in Half Moon Bay
We provide a written repair estimate after the on-site diagnosis and before any work starts. The climate out here barely asks for air conditioning most years, so the Lennox equipment we work on skews toward furnaces and heat pumps carrying the heating load through cool, damp winters.
Salt air is the real story for HVAC equipment on the Coastside. Outdoor condenser and heat pump coils corrode faster here than anywhere inland, and I see that on Lennox equipment as much as on any brand. A coil that would last 15 years in San Ramon can show real corrosion by year 8 or 9 out here, especially on units installed close to the water in El Granada or along Highway 1.
The older beach cottages near Main Street and the harbor tend to run simple, older Lennox furnaces, while some of the newer builds up toward Wavecrest run higher-efficiency heat pump systems. We check coil condition on every Coastside call regardless of the home's age, because the salt air affects new equipment too, just more slowly.
Lennox work we do in Half Moon Bay
Salt air corrosion on outdoor coils and cabinets. Condenser and heat pump coils on the Coastside pit and corrode faster than inland because of constant salt air exposure, which we see on Lennox units in Half Moon Bay, Moss Beach, and El Granada alike. We inspect coil condition on every visit out here and flag early corrosion before it turns into a refrigerant leak.
Heat pump defrost and reversing valve issues. The damp, cool Coastside winters put Lennox heat pumps through more defrost cycles than an inland climate does, and that extra cycling is where reversing valve and defrost control problems tend to show up first. We test the defrost board logic directly instead of guessing off symptoms alone.
Furnace ignition failures in older Main Street area cottages. The older Lennox furnaces in the beach cottages near Main Street and the harbor are hitting age-related ignition failures, usually a worn hot surface igniter or a flame sensor reading dirty from years of coastal humidity. Both are quick fixes once we've confirmed which one it is.
