The 91766, 91768, 91769, and 91797 ZIP codes are all within our regular service radius. Whether you’re in a 1950s stucco bungalow west of downtown or a mid-century tract home near Ganesha Park, our AC Repair & Installation team knows what to look for.
Why Crestview Heating & Air California Is Pomona’s Preferred AC Repair & Installation Company
Our reputation in Pomona is built on showing up and solving problems that other companies miss. With 19 years in the HVAC industry and a 4.8-star average across 250+ customer reviews, we’ve earned the trust of homeowners who’ve dealt with enough dispatch services to know the difference. Owner Marcus Feldman serves as our Service Manager, which means ownership-level accountability isn’t a slogan on our trucks — it’s how we run every job.
Pomona customers specifically mention our duct diagnostics in reviews. That’s because we don’t just swap capacitors and leave. In a city where the housing stock is overwhelmingly 1940s–1970s construction, the real problem is often hidden behind drywall or in a brutally hot attic. We find it. We fix it. And we explain what we found in plain language.
Our response time to Pomona is same-day for most repair calls booked before noon. Emergency HVAC service is available for after-hours failures, which matters when your system quits on a 108°F Saturday in July. From the older neighborhoods near Park Avenue to the postwar tracts around Ganesha Hills, we know the local building patterns, the common failure modes, and what it takes to keep a system running through Pomona’s extended cooling season.
Our AC Repair & Installation Services in Pomona
AC Repair
Pomona’s inland valley position — roughly 30 miles from the coast with no marine layer buffer — pushes summer design temperatures far above what coastal systems are sized for. Your unit runs harder and longer here than in West Covina or Azusa, which still catch some coastal influence. That stress shows up as capacitor failures, compressor overheating, and refrigerant leaks at flare connections that expand and contract through extreme thermal cycles.
Last summer we responded to a no-cooling call on a 1950s stucco bungalow near Park Avenue. The homeowner had already replaced the condenser fan motor, but the 3-ton Trane was still short-cycling. We found the original sheet-metal return plenum had partially collapsed behind the hallway drywall, choking airflow and causing the evaporator to ice over. We rebuilt the plenum with modern insulated ductboard and recharged the R-22 system, restoring full cooling capacity. This is the kind of hidden failure we see regularly in Pomona’s pre-1970 homes.
AC Installation
New system installation in Pomona is rarely a simple swap. The vast majority of local homes were built without central air or with undersized systems that can’t handle 105°F–110°F peaks. Full-system retrofits into homes with slab foundations and low-pitch roofs are common, and attic temperatures over 140°F can ruin flex duct before it’s even secured. We size equipment for actual local design temperatures, not generic LA County calculations, and we use duct materials rated for Pomona’s attic conditions.
For homes with existing floor furnaces or wall furnaces and no ductwork at all, we design complete forced-air conversions. These projects run toward the higher end of our installation range but transform livability in a way that window units or mini-splits alone cannot match.
AC Replacement
Replacement becomes the right call when your system is over 15 years old, uses phased-out R-22 refrigerant, or has suffered compressor failure. In Pomona, we also push toward replacement when we find a system was originally undersized for the actual heat load — a 2-ton unit from 1965 simply cannot maintain 75°F when it’s 108°F outside, and throwing money at repairs won’t change the physics. We evaluate your home’s envelope, duct integrity, and actual cooling load before recommending equipment.
Refrigerant Recharge
Low refrigerant in Pomona’s climate is almost always a leak, not normal consumption. The thermal stress on flare nuts, Schrader valves, and evaporator coils accelerates metal fatigue. We leak-test with electronic detectors and nitrogen pressure tests before recharging — adding refrigerant without finding the leak is a temporary fix that wastes your money and risks compressor damage. Recharges run $150–$650 depending on system size and refrigerant type, with R-410A systems generally costing less than legacy R-22 units that require reclaimed or alternative refrigerants.

Trusted Brands We Service in Pomona
We service and install equipment from nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Pomona customers, this means we don’t turn away jobs because “we don’t work on that.” We stock common capacitors, contactors, and refrigerants for Trane, Lennox, and Goodman systems locally, which keeps turnaround fast when your system fails during a heat wave. Our factory training across all nine brands lets us diagnose accurately instead of guessing, and our parts relationships mean we can source proprietary components without the delays that leave you sweating for days.
Common AC Repair & Installation Problems We See in Pomona Homes
- Collapsed return-air plenums in pre-1970 homes. In the older neighborhoods west of downtown, especially in the 91766 ZIP, we regularly find 1950s-era galvanized return-air plenums that have partially collapsed behind drywall from decades of negative pressure combined with seismic activity. The symptoms look like undersized or malfunctioning equipment — weak airflow, frozen coils, compressor short-cycling — until a physical duct inspection reveals the hidden blockage.
- Undersized 2-ton systems from the 1960s. Many Pomona tract homes were originally equipped with small units adequate for 85°F days, not the 105°F+ summits this inland valley now regularly sees. These systems run continuously without ever reaching setpoint, burning out compressors and freezing evaporators from insufficient airflow across the coil.
- Add-on wall and floor furnaces with no ductwork. A substantial share of older downtown-area homes still heat with original wall or floor furnaces and have no forced-air infrastructure at all. Adding central air requires complete duct system design, and Pomona’s low-pitch roofs and slab foundations make attic and crawl space routing a specialized challenge.
- Refrigerant leaks at thermally stressed connections. Pomona’s extreme temperature swings — from desert-cooled winter mornings to 110°F summer afternoons, plus Santa Ana wind events with single-digit humidity — cause repeated expansion and contraction at flare fittings and valve cores. We find slow leaks that drop charge over a season, not sudden failures, which is why annual pressure testing matters here.
Pricing for AC Repair & Installation in Pomona, CA
Here’s what typical AC work costs in Pomona’s market:
| Service | Price Range |
|---|---|
| AC Repair | $150–$650 |
| AC Installation | $3,500–$7,500 |
| Refrigerant Recharge | $150–$650 |
| Capacitor Replacement | $150–$650 |
What moves you within these ranges? System age and refrigerant type matter — R-22 work costs more as supplies tighten. Duct accessibility affects labor hours; a plenum rebuild behind finished drywall takes longer than a rooftop package unit swap. And full forced-air conversions in homes with no existing ductwork land at the top of installation pricing due to the scope of work.
We provide upfront written estimates before any work begins. Call (844) 560-6978 for a free estimate — we’ll diagnose your specific system and give you exact numbers for your Pomona home.

FAQs — AC Repair & Installation in Pomona
A frozen evaporator coil with a clean filter almost always means restricted airflow or low refrigerant. In Pomona’s pre-1970 homes, we find the original galvanized return-air plenum has partially collapsed behind drywall, choking airflow and causing ice buildup that looks like a refrigerant problem. The filter isn’t the issue — the hidden duct failure is. Call (844) 560-6978 and we’ll inspect the full duct path with a camera; estimates are free.
Yes, we design forced-air conversions that route new ductwork through attics, closets, and soffits without slab penetration. Pomona’s slab-foundation bungalows are common, and our approach uses the attic space with proper insulation rated for 140°F+ temperatures, plus strategic chase runs. The project costs more than a simple equipment swap but transforms your home’s comfort. Call (844) 560-6978 for a layout assessment and exact quote.
Probably not if the unit is correctly sized and still can’t reach setpoint. Pomona’s 105°F+ peaks exceed what many 1960s 2-ton systems were designed to handle, and no repair changes the equipment’s capacity. We measure actual heat load against your home’s envelope and duct integrity. If the math shows undersizing, we recommend right-sized replacement rather than throwing money at a system that can’t do the job. Call (844) 560-6978 for a load calculation.
Yes — Pomona’s extreme thermal cycling accelerates leak development at connections and valve cores. The inland valley’s temperature swings from cool winter mornings to 110°F afternoons cause repeated metal expansion and contraction. We recommend annual leak testing as part of maintenance, not just recharge-and-hope. If your system needs refrigerant more than once, there’s a leak to find. Call (844) 560-6978 for electronic leak detection and repair.
Start with a full home evaluation including heat load calculation, attic access assessment, and duct routing plan. Pomona’s 140°F attic temperatures and low-pitch roofs require insulated ductboard or metal duct with proper R-value, not standard flex that degrades quickly. Many 1963 homes in the 91766 and 91768 areas also have electrical panels that need upgrading for modern HVAC loads. We handle the complete scope, not just equipment. Call (844) 560-6978 to schedule an evaluation — estimates are free.
