AC & HVAC repair in San Ramon.
Owner-operated HVAC repair and installation, run out of San Ramon, with written quotes before any work starts.
I live and work in San Ramon, so this is the city I know best. The shop is on the Bishop Ranch side, and most of our calls here come from the Tri-Valley inland corridor where summer afternoons push past 95 degrees and the cooling load does the heavy lifting. Winters stay mild, lows around 35 to 40, so the furnace runs gently but the AC and the heat pump earn their keep.
The housing tells you what the job will be before I open the panel. A big share of San Ramon is 1980s and 90s tract construction, the Twin Creeks and Country Club neighborhoods, where the original gas furnace and condenser are now closing in on 30 years. That is the age where compressors start failing and heat exchangers crack, and a third repair stops making sense. The Gale Ranch and Dougherty Valley builds from the 2000s are a different animal, usually two-zone systems where the real work is control boards, zone dampers, and keeping the equipment tuned. Near the Crow Canyon corridor there is a pocket of older 1960s and 70s homes where the ductwork was never great, and a ductless retrofit often beats fighting bad duct runs.
Every visit starts with a $75 diagnostic, and that fee comes off the bill when you book the repair with us. Before I touch anything beyond the diagnosis you get a written, itemized quote, so the number you approve is the number you pay. We are EPA Section 608 Universal certified, which matters the moment refrigerant is involved, and we are licensed under CSLB #1136642.
The repairs and installs we run in San Ramon
We cover the full range here: AC repair when a condenser quits in an August heat wave, furnace repair through the cooler months, heat pump service, and ductless mini-split work for the additions and converted spaces where central air never reached well.
On the install side, the most common San Ramon job is pulling a 25-year-old gas furnace and original AC out of a Twin Creeks-era tract home and putting in a heat pump. That swap often needs a sub-panel because the older electrical service runs tight, and I include that assessment in the estimate so the electrical cost is not a surprise after the fact. For the newer Dougherty Valley homes the work leans toward zone diagnostics and maintenance rather than replacement, because the equipment still has years in it.
Heat pumps fit this climate, and we know the equipment
Cooling is the bigger workload in San Ramon, and a heat pump handles both the long cooling season and the mild winter on one system. That is why so many of our replacements here move away from the old furnace-plus-AC pairing.
We are a Daikin authorized servicer and I trained at the Daikin factory, and I have also completed Mitsubishi Electric factory training, so the Mitsubishi ductless units we put in older Crow Canyon homes are equipment I know cold. We install Goodman as well when the budget calls for it. When a job is a full system design rather than a repair, I hand it to our HVAC division, Bay Area HVAC Service, which is the same company and the same crew under a name dedicated to heat pump and furnace installs.
Rebates, and how we handle them honestly
San Ramon sits in MCE electricity territory, and that opens up heat pump rebate programs that genuinely change the math on a conversion. I will not quote you a dollar figure off the top of my head, because the amounts and the funding move around by territory and by cycle.
Here is how we actually do it. We work with BayREN, MCE, PG&E, and EBCE/Ava, plus manufacturer instant rebates, and we confirm what is truly paying at the time we write your estimate. On qualifying installs we file the application alongside the permits, not as an afterthought. We also run the DOE Home Energy Score audit through BayREN, which is a useful starting point if you are weighing how far to take an upgrade. See our home energy assessment for that.
Why San Ramon homeowners call us
I am based here, so when something fails I am usually close. I am the owner, and I stand behind every job: the work, the invoice, and the warranty.
We run seven days a week. The $75 diagnostic is waived when you book the repair, the quote is written and itemized before work begins, and our maintenance plan keeps you ahead of the breakdowns instead of waiting for the first hot day to find out the condenser is done.
Common questions, San Ramon.
- Do you charge for a diagnostic visit in San Ramon?
Yes, the diagnostic is $75. If you book the repair with us, that $75 comes off the bill. You get a written, itemized quote before any repair work starts, so you approve the number first.
- Should I replace my old AC and furnace with a heat pump?
In San Ramon it usually makes sense. Cooling is the bigger load here and a heat pump covers both the cooling season and our mild winters on one system. If your furnace and condenser are from the 1980s or 90s and pushing 30 years, a heat pump conversion is often the better long-term call. On older homes it may need a sub-panel, which I assess up front and include in the estimate.
- Are there rebates for a heat pump in San Ramon?
San Ramon is in MCE electricity territory, so heat pump rebate programs are a real factor here. We work with BayREN, MCE, PG&E, and EBCE/Ava, plus manufacturer instant rebates. Amounts and funding vary by territory and cycle, so we confirm exactly what is paying when we write your estimate, and we file the application alongside the permits on qualifying installs.
- Are you licensed and certified to work on my system?
Yes. We are CSLB licensed under #1136642 and EPA Section 608 Universal certified, which is required any time refrigerant is handled. I trained at the Daikin factory and have completed Mitsubishi Electric factory training as well.
