Fremont is spread out. Do you cover all of it from San Ramon and how far is it?

We cover the whole city. From San Ramon it is roughly 30 to 40 minutes down 680 depending on which part of Fremont. We pair it with Oakland-corridor and Pleasanton work to keep the routing efficient.

My Mission San Jose home runs hotter than my old place. Should the Lennox be bigger?

Not necessarily bigger, but properly staged and clean. We check sizing, coil condition and charge before recommending anything, and we quote in writing.

Do you handle both the heating and cooling side on one visit?

Yes. We diagnose the full system, heat pump or furnace plus AC, in one visit and give you a single written quote for what it needs.

Lennox in Fremont

Lennox heating and cooling in Fremont.

Fremont is large and varied, stretching from the bay-cooled flats of Centerville and Newark-adjacent areas up to the warmer Mission San Jose hills against the foothills. Cooling load grows as you move inland and uphill. The housing spans 1950s and 1960s tracts, newer subdivisions and some older Niles district homes, mostly ducted single-family. Lennox systems here are typically standard ducted heat pumps and AC plus furnace pairings.

A Lennox system suits Fremont well, and for the warmer Mission San Jose side a two-stage condenser earns its place. The honest caveat holds. Lennox parts are proprietary and dealer-restricted, so a control board or a blower module takes longer and costs more than the Carrier or Trane equivalent. Across most of Fremont's moderate climate a short wait is manageable, and I give you the real timeline before we order.

Common repairs we do

What we close on the truck.

Furnace control board lockouts in older Centerville and Niles homes. Older Fremont furnaces lock out on a failed Lennox ignition board or a tired flame sensor. I clean and test the sensor and igniter first, since the board is dealer-restricted, and I will not swap a good one.
Condenser running hot on Mission San Jose hillside lots. On the warmer hillside side of Fremont, Lennox condensers run harder and trip on high head pressure when coils foul. I clean the coil and verify charge under EPA 608 before assuming a compressor problem.
Heat pump reversing valve faults on the bay side. On the cooler Fremont flats, heat pumps run heat more, and a stuck reversing valve leaves the system blowing cold. I confirm the valve and its solenoid coil rather than chasing the charge.
