Is your Peninsula technician actually based near San Mateo, or is that just marketing?

It is a real assignment, not a marketing line. Our Peninsula technician is based in San Mateo, which is why calls here, along with Belmont and Foster City, tend to get faster appointment windows than cities that require a full drive out from San Ramon.

Is a Heil furnace a reasonable choice for an Eichler in the Highlands, or should I stick with radiant heat?

Depends on the house and what has already been done to it. If forced air ductwork already exists and was sized correctly, a Heil furnace or heat pump is a solid, cost-effective option. If the ducts were added as an afterthought and are undersized, I will tell you that upfront, because putting new equipment on bad ductwork just moves the problem instead of fixing it.

What actually happens during the $99 diagnostic?

I pull fault codes off the control board, test the components those codes point to, and check airflow or pressures depending on the equipment and how the home is set up. You get a written, itemized quote before any repair starts, and the $99 comes off the total if you approve the work that same visit.

Heil in San Mateo

Heil in San Mateo kitchens.

San Mateo sits in the middle of the Peninsula and runs warmer and drier than the fog-heavy cities closer to the coast. The housing mix is wide: postwar bungalows near 25th Avenue and the restaurant row along B Street sit alongside the Eichler tract homes up in the San Mateo Highlands, built in the late 1950s with radiant slab heat that a lot of owners have since converted or supplemented with forced-air equipment. Heil shows up across both, ICP-family gear on the same platform as Carrier and Bryant, usually chosen because it is straightforward to service and fits a normal remodel budget.

The Eichler conversions are the ones I pay closest attention to, because the ductwork was often added decades after the house was built, run through an attic space that was never designed for it. Undersized or poorly routed ducts restrict airflow, and that shows up as high-limit switch trips or a furnace that short-cycles even though the burner and igniter are fine. I pull fault codes off the control board first, whether through blink codes or the Ion communicating system, and check static airflow before touching a component.

Our HVAC work runs under Bay Area HVAC Service, and San Mateo is where our Peninsula technician is actually based, so response times here, and in Belmont and Foster City nearby, tend to be some of the fastest in our whole coverage area. Diagnostic is $99, waived if you book the repair. Every quote is written before work starts, and we run calls seven days a week. CSLB license 1136642, EPA Section 608 Universal certified.

Common repairs we do

What we close on the truck.

High-Limit Switch Trips From Undersized Retrofit Ductwork. In Eichler homes where forced air was added years after the original radiant slab system, the duct runs are sometimes undersized for the furnace feeding them. Restricted airflow causes the heat exchanger to run hotter than it should, which trips the high-limit switch and shuts the burner down mid-cycle. I check static pressure and duct sizing before assuming the switch or the furnace itself is the problem, because replacing parts without fixing the airflow just repeats the trip.
Hot Surface Igniter Failure From Frequent Cycling. A furnace that short-cycles from restricted airflow puts extra wear on the hot surface igniter, since it goes through more ignition attempts than a system running normally. The element cracks sooner than it should, and the furnace eventually locks out on a no-ignition fault. I confirm the igniter itself is out of spec with a meter, but I also address whatever is causing the cycling in the first place, since a new igniter alone will not hold up long under the same conditions.
Run Capacitor Wear on Peninsula Summer Cooling Loads. San Mateo runs warmer through the summer than the coastal cities nearby, and outdoor Heil condensers here put in a longer cooling season than units in Pacifica or Daly City. That extra runtime wears down the run capacitor at a faster clip, and a weak capacitor shows up as a compressor that hums but does not start, or a fan that spins slower than it should. I test actual capacitance with a meter before replacing it.
