Heating & cooling
AC & HVAC repair in Mountain View.
Heating repair and first-time cooling for Mountain View homes, from Old Mountain View bungalows to Shoreline townhomes.
Mountain View was built for a climate that did not need air conditioning. The bay keeps most summer afternoons in the upper 70s and low 80s, so a large share of the older housing here has no cooling at all. That is changing. The hot stretches now push past 90 a few times a year, and the most common install call we get in this city is adding cooling to a house that never had it.
The three ZIPs each tell a different story. Old Mountain View in 94041 is Craftsman and bungalow stock, and plenty of those houses still heat with a wall furnace or floor furnace and have no ductwork anywhere. The Cuesta and Monta Loma tracts in 94040 are 1950s single-story homes with low-slope roofs and almost no attic, which makes duct routing tight and pushes a lot of jobs toward ductless. The 94043 side toward Shoreline is newer townhome construction with compact ducted systems and, increasingly, builder-installed heat pumps.
ADRIUM is owner-operated out of San Ramon and runs seven days a week. We are EPA Section 608 Universal certified and CSLB licensed under #1136642. The diagnostic is $75, credited toward the repair when you book it with us, and every quote is written and itemized before work starts.
Adding cooling to a house that never had it
For the 94041 bungalows and the Monta Loma tracts, the honest answer is usually ductless. A wall-mounted mini-split head or two covers the living space without inventing duct routes through a house that has nowhere to put them. If the wall furnace is also near the end, a multi-zone heat pump replaces heating and cooling in one project. We install Mitsubishi and Daikin for this work. I trained at the Daikin factory and have completed Mitsubishi Electric factory courses, so commissioning gets done by the book, not by feel.
Where ducts do exist, in the later 94040 stock and the Shoreline townhomes, we look at the ducts before quoting a condenser. A 1950s supply trunk sized for gentle gas heat will choke a modern air conditioner, and bolting new equipment onto starved ducts is how you end up with a cold hallway and a warm bedroom.
Wall furnaces, floor furnaces, and the heating calls
A lot of shops will not touch a wall furnace anymore. We service them: thermocouples, gas valves, pilot assemblies, and the safety checks that matter on a heater living inside a hallway wall. When one is genuinely done, we lay out the real options in writing, a like-for-like swap where that still makes sense, or a heat pump that finally adds cooling to the house in the same project.
On the ducted furnace side the faults are the usual suspects: igniters, flame sensors, pressure switches reading a blocked condensate line. The townhome heat pumps near Shoreline mostly fail at the board and sensor level, and we carry the meters to prove which part it is before anything gets ordered.
Replacement and rebates
Mountain View sits in Silicon Valley Clean Energy territory for generation, and heat pump incentives here stack from a few directions. We work with BayREN and PG&E programs plus manufacturer instant rebates, and amounts move by cycle, so we confirm what is actually paying when we write the estimate. Our installs carry a 10 year parts and labor warranty, and we size equipment to the measured load, not a square-footage rule of thumb.
Common questions, Mountain View.
- Can you add air conditioning to a Mountain View house with no ducts?
Yes. That is the most common install call we get here. A ductless mini-split adds cooling, and heating if you want it, without cutting duct routes into a 1950s house that has no attic to hold them. We install Mitsubishi and Daikin and quote the whole project in writing before anything starts.
- Do you still service wall furnaces and floor furnaces?
Yes. Much of Old Mountain View still heats with them. We handle thermocouples, gas valves, pilot assemblies, and the safety testing that matters on these units. If one is beyond safe repair, we say so in writing and price the options, including a heat pump that adds cooling at the same time.
- How much is the service visit in Mountain View?
The diagnostic is $75, and it is credited toward the repair when you book it with us. You approve a written, itemized quote before any work starts.
