Air Conditioning & Heating Company Serving North Pomona, CA Since 1980
North Pomona is a neighborhood with character — the Victorians and Craftsman bungalows of the Lincoln Park Historic District, the view homes of Ganesha Hills, the tree-lined streets around Cal Poly Pomona. RC Air has kept homes like these comfortable since 1980, which in an older neighborhood is as much about smart retrofits as it is about repairs. We’re family-owned, Bryant-authorized, and rated 4.9 stars across 775+ Google reviews, and since we dispatch from nearby Rancho Cucamonga, a North Pomona visit is a short trip — book before 5pm in cooling season and same-day or next-morning service is usually doable. Financing available on new systems.

HVAC Services Built for North Pomona Homes
What sets North Pomona apart is its age. Much of the neighborhood went up long before central air was a given — the Lincoln Park district alone holds hundreds of homes built between the 1890s and the 1940s, and Ganesha Hills mixes early craftsman bungalows with mid-century ranches across the slopes. They’re beautiful houses, but they come with plaster walls, tight chases, and ductwork that was either added decades after the fact or was never there to begin with. Heating and cooling an old home well is a different craft than dropping a system into new construction — and it’s work we genuinely like: right-sizing the equipment, routing ducts (or going ductless) without cutting into original finishes, and fixing the undersized returns that leave half the rooms stuffy.
The valley heat doesn’t do old houses any favors, either. Pomona summers run hot — long stretches of high-90s and triple digits — and Santa Ana winds pull dry heat and dust down out of the nearby San Gabriel foothills. Older homes feel all of it: leaky envelopes, thin insulation, and single-pane windows mean a marginal system never quite catches up. So instead of just swapping the part that failed, we read the whole house — capacity, airflow, duct sealing, the insulation gaps, filtration — and get a 1920s home holding its temperature the way a new build would.
Repairs, full system replacements, heat pumps, ductless mini-splits, indoor air quality, seasonal maintenance — RC Air covers all of it across North Pomona, with pricing in writing before we start and Bryant equipment backed by a registered 10-year parts warranty.

Reliability, Efficiency, Expertise
Problems We Hear About A Lot In North Pomona
- "Our 1920s Craftsman has never had real air conditioning — is that even possible?" It is. In historic Lincoln Park homes we add cooling with carefully routed ducts or ductless mini-splits that leave your plaster, moldings, and ceilings intact — modern comfort without gutting the character.
- "The vents are there, but half the rooms never cool off." Retrofitted ductwork in older North Pomona houses often has undersized or missing returns, so the air simply can't circulate. We redesign the airflow instead of just topping off the refrigerant and hoping.
- "I don't want ductwork wrecking my original walls and ceilings." Understandable — which is exactly why we lean on high-efficiency ductless systems and discreet routing in the historic districts. You keep the period details and still get even, room-to-room comfort.
- "Our Ganesha Hills place has the views, but the AC dies every heat wave." Hillside homes catch full afternoon sun, and tired equipment folds under that load. We work through the whole system — charge, airflow, sizing — so it stops quitting on you in July.
- "We're still heating with the original wall furnace." A lot of North Pomona homes are, and those units are often inefficient and worth a safety check. We'll walk you through modern furnace or heat-pump options that suit an older floor plan.
- "A whole new system for an old house sounds expensive." It doesn't have to land all at once. You get an itemized quote up front, and financing on qualifying installs turns it into a manageable monthly payment.

About RC Air And Our Connection To North Pomona
Founded in 1980 by Clark Williams, RC Air Heating & Air Conditioning is a third-generation family business serving Rancho Cucamonga, North Pomona, and the broader Inland Empire. Three generations of Williams family techs have grown the company one job at a time — no franchise, no call center, just local accountability and a phone that gets answered.
North Pomona sits at the north end of the city, tucked up against the San Gabriel foothills and set apart from Pomona proper by the 10 — a stretch defined by its historic neighborhoods more than anything else. The Lincoln Park district’s 800-plus homes span the 1890s to the 1940s, Ganesha Hills layers craftsman bungalows and mid-century ranches across the slopes, and the streets around Cal Poly Pomona hold some of the densest historic housing anywhere in the region. Homes like these reward a contractor who actually understands old construction — how to add modern cooling without harming original detail, how to right-size for a leaky 1910 envelope, how to make a wall-furnace house genuinely comfortable. We bring Bryant equipment, a registered 10-year parts warranty, and the 775+ five-star reviews we’ve earned across the Inland Empire to every one of them.
Frequently Asked Questions
Yes — it’s some of our favorite work. Depending on the house, we’ll add cooling with carefully routed ductwork or with ductless mini-splits, and we start with a real load calculation so the system is sized for your home’s actual envelope rather than a rule of thumb.
It shouldn’t, and preserving that character is the whole point of how we approach it. Ductless systems and discreet routing let us leave plaster, moldings, and ceilings intact while still delivering even comfort, so the house keeps its period detail.
Often, yes. Those older units tend to be inefficient and worth a safety look, and there are modern furnace and heat-pump options that fit an older floor plan cleanly. We’ll lay out the trade-offs and let you decide. A home fire is never less expensive (or stressful) than a new heating unit.
Absolutely — repairs, replacements, and new installs. Those homes catch a lot of afternoon sun and often run older equipment, so we pay close attention to sizing and airflow to keep them comfortable through a heat wave.
It depends on the size and efficiency you choose and whether the ductwork needs attention, so you’ll get a written quote with options before any work starts. And yes — we finance qualifying installs, which turns a new system into a monthly payment instead of one lump sum.
Yes, we provide warranties on our services and installations, giving you peace of mind knowing your investment is protected. Specific warranty details will be provided at the time of service.
