Airflow Heating & Air is a family-owned, CSLB-licensed HVAC contractor that repairs, replaces and installs air conditioners, furnaces, heat pumps and ductless systems in Davis, CA. We work from Old North Davis and Village Homes out to Mace Ranch, Wildhorse and West Davis, and offer 24/7 emergency service.
The two Davis questions we hear most: do I have to go all-electric, and is a heat pump worth it here? At the time of writing (2026), the city's all-electric reach code applies to new construction, not to replacing equipment in an existing home. Most Davis homeowners can still choose a gas furnace or a heat pump. We lay out both, price both, and handle the City of Davis permit.
What Davis actually requires when you replace a furnace or AC
Davis has a reputation for strict energy rules, and part of it is earned. The City Council adopted an energy reach code in September 2019, and the California Energy Commission approved it in January 2020. It applies to new buildings. Builders can go all-electric, or build with gas and meet tougher efficiency targets plus pre-wiring for future electric appliances.
For existing homes, the picture is different. The city's Climate Action and Adaptation Plan sets a carbon-neutral goal of 2040. An early draft proposed requiring electric equipment when gas systems wear out, but the city revised that to voluntary after public comment. So if your furnace dies in January, you are not forced into a heat pump. You do still need a permit, and the new system must meet California's Title 24 energy code, which usually means HERS verification such as duct leakage testing.
Pulling the permit
The City of Davis Building Division takes minor mechanical permits (furnace, AC, both, and whole-house fans) through an online submittal portal. We file it, then schedule the inspection and HERS test.
Outside city limits
El Macero and Willowbank sit just outside Davis in unincorporated Yolo County. Those addresses get permits from the county, not the city. We check the parcel before we file.
Who sells your power
Valley Clean Energy has supplied electricity in Davis since June 2018. PG&E still delivers it, bills it and supplies gas. That matters when we compare the running cost of a heat pump against a gas furnace.
Heat pump or gas furnace in a Davis house
Davis winters are mild by heat pump standards, with foggy, frosty mornings rather than deep cold. A correctly sized heat pump handles that well and replaces both your furnace and your AC with one outdoor unit. It makes the most sense when your AC is also near the end, your electrical panel has room, and you want to move off gas over time.
A new gas furnace can still be the right answer. If the AC is only a few years old, or the panel would need a costly upgrade, replacing just the furnace keeps the cost down. Incentives for heat pumps come and go. Statewide programs like TECH Clean California have run out of single-family funds before, so we check what is open at the time of your quote instead of promising a rebate.
Sizing cooling for Delta breeze nights
Summer in Davis is hot and dry, with average July highs in the low 90s and heat waves that push past 100°F. Then the Delta breeze comes in from the southwest and nights often drop into the 50s. That pattern changes how we size a system.
- Don't oversize. Your AC only has to carry the afternoon peak. An oversized unit short-cycles, and the cool nights mean it rarely runs long enough to catch up anyway.
- Whole-house fans pair well. Many Davis households flush the house with night air, then close up by morning. A fan plus a right-sized AC or heat pump can cut cooling hours. The city's online permit portal lists whole-house fans as a minor permit.
- Watch the attic ducts. Most 1970s through 1990s Davis tract homes run ducts through the attic. Leaky ducts waste the cool air you paid for. Duct sealing often helps more than a bigger unit.
Davis homes we see most
Village Homes and passive solar houses
Village Homes was laid out by Michael and Judy Corbett in the 1970s with east-west streets and north-south lots so houses could use passive solar heating. These homes often need less heating and cooling than their size suggests. We size from a load calculation, not square footage, and look for places a ductless head makes more sense than new ductwork.
Student rentals and small landlords
Davis runs a Rental Resources program under Municipal Code Article 18.11. Rentals with one to four units are registered, and a sample is inspected each year. If you own a rental near campus, a reliable furnace and clean filters are part of keeping the unit habitable. We can schedule tune-ups between tenants.
Smoke, pollen and winter wood burning
Davis is in the Yolo-Solano Air Quality Management District. From November through February the district issues voluntary "Don't Light Tonight" advisories when particulate levels are forecast to be high. Add summer wildfire smoke and spring pollen from the surrounding farmland, and filtration earns its place. A sealed duct system with a deeper media filter or an air purifier keeps more of that out.
Heat pump installation
All-electric heating and cooling for Davis homes moving off gas, with the panel checked before we quote.
AC repair
Fast diagnosis when the AC quits in a 100°F stretch before the Delta breeze returns.
Furnace repair
Gas furnace fixes for foggy Davis winters, including rentals that need heat back the same week.
Ductless mini-splits
A good fit for Village Homes, additions and garage conversions where running ducts is hard.
Duct sealing
Attic duct repair in older tract homes, tested to meet the Title 24 leakage limits.
Air filtration
Better filters for smoke season and harvest dust blowing in from the fields around town.
Before we quote a system in Davis, we check
- Whether the address is inside city limits or in unincorporated Yolo County
- Your electrical panel capacity, if a heat pump is on the table
- A room-by-room load calculation, especially for passive solar homes
- Attic duct condition and likely HERS leakage results
- Which heat pump incentives are actually open that month

Questions Davis homeowners ask
Does Davis require me to replace my gas furnace with a heat pump?
Not at the time of writing (2026). The City of Davis reach code covers new construction, and the Climate Action and Adaptation Plan treats electrification of existing homes as voluntary. You still need a permit and a system that meets California's Title 24 energy code.
Who issues the HVAC permit for a Davis home?
Inside city limits, the City of Davis Building Division issues it, and furnace and AC permits can be submitted online. Homes in El Macero or Willowbank are in unincorporated Yolo County, so the county handles those. We pull the permit as part of the job.
I'm a Valley Clean Energy customer. Does that change anything for a heat pump?
VCE supplies the electricity, while PG&E delivers it and supplies your gas. Your rate plan affects how a heat pump's operating cost compares to gas. Bring a recent bill and we'll walk through it with you.
Is a heat pump enough heat for a Davis winter?
For most homes, yes. Davis winters bring fog and frost but rarely long hard freezes. A heat pump sized from a proper load calculation, with sealed ducts, keeps a typical Davis house comfortable.
Can I add a whole-house fan instead of a bigger AC?
Often that's the smarter move in Davis. The Delta breeze cools most summer nights, and a whole-house fan pulls that air through the house. You still need AC for the hottest afternoons, but it can run less.

We are thrilled with Oleg and the work he and his team did to install a heat pump, remove the A/C and detangle our hydronic heating system! The price was great, the work was great, the follow-up and follow-through were great. The team was super fast, getting it all done in one day. Oleg is such a great guy - extremely thorough, kind and does such good work. The inspector said "wow, he did a really clean job". We will highly recommend Oleg to anyone who needs HVAC!

I can’t say enough about Oleg and his staff, they were truly professional from initial diagnosis to installation. My heating system ceased working and my family and I were left in the cold. I reached out to Airflow based on the superlative reviews I saw in my research. Oleg came out and knew exactly what my issue was and also uncovered a problem with my dampening system which for the past 25 years no one was able to correct. Oleg told me what I needed, no sales pressure, promised to send me an estimate that day which he did. The cost was exceptionally fair and coupled with the impression Airflow had made I decided to go with them without further research or estimates for price comparisons….wasn’t necessary, this was the guy. I requested early January thinking I could tough it out, however it just got too uncomfortable in the house. I reached out to Oleg who by the way was quite busy and he moved some stuff around and did the entire install the next day. My home is now warm and comfortable. Oleg was a pleasure to deal with. This guy is an Einstein when it comes to HVAC and I will not do business with anyone else from this point forward. Thanks Oleg, you and your staff are top notch. My HVAC system has never operated at this level before.

We highly recommend Airflow Heating & Air for your heating or air conditioning needs. Oleg and his crew installed 2 independent systems in our 2-story home built in the early 1900s. Both the Daikin mini-split and the Goodman heat pump system work to perfection, keeping our house cool in the summer and warm in the winter. What we appreciated most, along with professionalism and a clean job site, was Oleg’s genuine interest in ensuring that we were completely satisfied with the installations.

I’ve used Airflow Heating and Air for years for both my personal home and multiple rental properties. These guys are truly top-notch. What sets Airflow apart is their honesty and thoroughness. Instead of immediately pushing a full system replacement like many HVAC companies do, AirFlow takes the time to properly diagnose the issue and recommend repairs whenever possible, always keeping my budget in mind. They clearly explain the options so you can make an informed decision without pressure. When a full replacement is necessary, they’re just as impressive. I’ve trusted Airflow with two complete system replacements, and both were smooth, professional, and fairly priced. They handled the entire process including permits and inspections which made everything incredibly easy for me and my tenants. Overall, Airflow Heating and Air has been reliable, professional, and easy to work with every step of the way. Their communication is excellent, their work is high quality, and they truly stand behind what they do. I trust them completely and wouldn’t hesitate to recommend them to anyone needing HVAC service! 10/10

Oleg was referred to me by my neighbor. My neighbor said he will never go with anyone else for his HVAC needs - and I now I understand why! Both times I reached out, he responded to me within minutes, and came out to my house the very next day. He's honest, reliable, reasonably priced, and just an all around cool dude. Thanks, Oleg!
