We’ve been driving out to Chino Hills since Redwood Heating & Air opened 13 years ago. Gregory Hahn founded this company and still leads every technical decision, which means when you call, you’re getting a Master Technician’s judgment, not a dispatcher reading from a script. We know the difference between a ridge home in the Carbon Canyon corridor and a canyon-bottom property off Pipeline Avenue, and we know both need different load calculations even if the square footage looks identical on paper.
Chino Hills was built fast and built big, almost entirely between 1985 and 2005. Those 2,500–4,500 square foot two-story tract homes are now hitting a wall: original R-22 heat pumps that can’t be repaired because the refrigerant is obsolete, ductwork baking in 140°F attics, and compressors that weren’t sized for the 115°F days that nearby Chino recorded in September 2022. We’re the Heat Pump & Mini Split team that knows how to replace these legacy systems with equipment that actually fits this city’s unique climate and housing stock.
Why Redwood Heating & Air San Diego Is Chino Hills’s Preferred Heat Pump & Mini Split Company
Our reputation in Chino Hills is built on showing up and fixing it right. We’ve got 428 verified reviews averaging 4.6 stars across 13 years of operation, and a significant share of those come from Inland Empire homeowners who were tired of technicians pushing one brand or quoting repairs that didn’t last. Gregory Hahn holds a Master Technician designation, and that credential is on the truck that rolls up your driveway, not locked in a corporate office three counties away.
Response time matters when your heat pump dies in August and the attic ductwork is radiating heat into your second floor. We typically reach Chino Hills properties within 90 minutes during emergency calls, and we carry diagnostic tools and common parts for nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That multi-brand fluency means we don’t try to shoehorn your system into whatever our warehouse happens to stock.
We also understand the local terrain in a way that affects your comfort directly. A west-facing home on a ridge in the Carbon Canyon corridor can run its system 30–40% harder than a north-facing home of identical square footage two blocks away. Our Manual J load calculations account for that. Rule-of-thumb tonnage sizing will consistently get it wrong here, and we don’t do rule-of-thumb.
Our Heat Pump & Mini Split Services in Chino Hills
Heat Pump Repair
Most heat pump repair calls we get in Chino Hills involve original R-22 systems that have finally developed a leak they can’t recover from. The EPA phase-out means refrigerant is scarce and expensive, and the equipment itself is 25–40 years old. We diagnose honestly: if the compressor is drawing high amps and the coils are corroded, we’ll tell you that repair is throwing money at a dead system. When repair makes sense, typical Chino Hills heat pump repair runs $150–$650 depending on whether we’re replacing a capacitor, a reversing valve, or a blower motor.
Heat Pump Installation
This is the dominant conversation in Chino Hills right now, and for good reason. That massive cohort of 1985–2005 construction is hitting end-of-life simultaneously, and full replacement is usually the only viable path. We size every installation with a proper Manual J load calculation that accounts for your home’s solar exposure, elevation, and ductwork condition. A typical 3,500 square foot two-story home in Chino Hills needs a system in the 4–5 ton range, but we’ve seen ridge homes need 20% more capacity and well-shaded canyon homes need less. Heat pump installation in Chino Hills runs $3,500–$7,500, with Daikin and Bryant systems being popular choices for their efficiency in high-heat conditions.
Mini Split Installation
Mini splits solve problems that central ductwork can’t, especially in Chino Hills’s older tract homes where attic ducts are disintegrating. We install single-zone systems for garage conversions and additions, but we’re seeing strong demand for multi-zone ductless systems that replace failing central heat pumps entirely. A Daikin multi-zone system can cool four bedrooms independently, each with its own thermostat, without running new ductwork through that 140°F attic. In the Carbon Canyon corridor, we replaced a failing 25-year-old R-22 heat pump on a west-facing ridge home with a new Daikin multi-zone mini split system. The original undersized 3-ton unit couldn’t keep up with the 115°F September 2022 heat, and the homeowner was spending $400/month on electricity. Their summer bill dropped by more than half.
Mini Split Repair
Ductless systems are reliable, but they’re not immune to the dust and pollen that blow through Chino Hills during Santa Ana wind events. Clogged filters, refrigerant leaks at flare connections, and failed inverter boards are the most common issues we see. Because we service Daikin, Bryant, Carrier, and American Standard mini splits regularly, we carry replacement parts that let us complete most repairs same-day rather than ordering from a warehouse and making you wait.

Trusted Brands We Service in Chino Hills
We don’t push one manufacturer because no single brand is right for every Chino Hills home. We’re certified and experienced across nine major HVAC brands, which means we diagnose based on your actual needs, not our supplier relationship. For the Inland Empire’s extreme heat, we often recommend Daikin for mini split efficiency, Bryant for heat pump durability, or American Standard for balanced performance. We stock common parts locally for faster turnaround, and if your system is a brand we don’t typically carry, we’ll source what we need rather than tell you to call someone else.
Common Heat Pump & Mini Split Problems We See in Chino Hills Homes
- Original R-22 systems lose cooling capacity as refrigerant leaks become irreparable. The EPA phase-out has made R-22 prohibitively expensive, and most Chino Hills homes with original equipment are past the point where recharging makes financial sense. We see this weekly in the 91709 ZIP code.
- Second-floor ductwork in attic spaces exceeding 140°F causes rapid heat gain. Your heat pump works fine, but the cooled air is warming back up before it reaches your bedrooms. Mini splits bypass this problem entirely by delivering conditioned air directly to each room.
- Hilltop homes with high solar exposure suffer from undersized original units that cycle too long. The builder’s 3-ton unit was fine for the model home facing north. Your west-facing ridge home needs more capacity, and the compressor is burning out trying to keep up. Proper load calculation prevents this.
- Santa Ana wind events overwhelm heat pumps with extreme temperatures and dust infiltration. These dry, hot winds push systems past their design limits and clog outdoor coils. We see a spike in emergency calls every September when the winds hit hardest.
Pricing for Heat Pump & Mini Split in Chino Hills, CA
We’re upfront about costs because nobody likes sticker shock after the work starts. Here’s what heat pump and mini-split services typically run in the Chino Hills market:

Installation costs vary with system size, electrical upgrades needed, and whether we’re replacing ductwork or going ductless. A single-zone mini split for a garage conversion might land at the low end. A whole-home multi-zone system replacing a failed central heat pump with electrical panel upgrades will push toward the top. We always provide a written, itemized estimate before any work begins. Estimates are free, and there’s no obligation to proceed. Call (844) 875-9451 to schedule yours.
We Also Serve Cities Near Chino Hills
Our service area extends throughout the western Inland Empire and northern Orange County. We regularly work in Los Serranos, Chino, Diamond Bar, and Yorba Linda, and our technicians understand the subtle differences between these markets. Chino’s older pre-1980 housing stock faces different challenges than Chino Hills’s uniform tract construction. Diamond Bar’s hillside homes share some of Chino Hills’s solar exposure issues. Yorba Linda’s larger lots and estate homes need different system sizing. Wherever you are, we bring the same Master Technician-level diagnosis.

FAQs — Heat Pump & Mini Split in Chino Hills
Replace it. Original R-22 equipment from the 1990s cannot be legally recharged with new refrigerant, and reclaimed R-22 costs more than $100 per pound when you can find it. Most 1990s heat pumps in Chino Hills need 8–12 pounds for a full charge, so even a “simple” leak repair runs $800–$1,200 before addressing the actual mechanical failure. For that money, you’re halfway to a new system that uses modern R-410A or R-32 refrigerant and qualifies for much higher efficiency ratings. Call (844) 875-9451 and we’ll inspect your system honestly, but expect us to recommend replacement.
Most 3,500 square foot two-story homes in Chino Hills need a 4–5 ton heat pump, but the exact size depends on factors that square footage alone misses. West-facing ridge homes in the Carbon Canyon corridor often need 20% more capacity than north-facing homes of identical size. Homes with degraded attic ductwork may need upsizing or ductless supplementation to deliver adequate cooling to second-floor bedrooms. We perform a Manual J load calculation for every installation, not a rule-of-thumb estimate. Call (844) 875-9451 to schedule a free assessment.
Yes, a multi-zone ductless system can cool an entire home, and it’s often the best solution for Chino Hills’s 1985–2005 tract homes with failing attic ductwork. A Daikin or Bryant multi-zone system places a compact outdoor unit outside and individual wall-mounted or ceiling cassette heads in each room, each with independent temperature control. No ductwork runs through that 140°F attic. We’ve installed whole-home mini splits in homes from Los Serranos to the Chino Hills Parkway corridor, and homeowners consistently report better bedroom cooling and lower electric bills than their old central systems delivered.
Santa Ana winds push temperatures 10–15°F above normal and blow dust and debris into your outdoor coil, reducing the system’s ability to reject heat. Your heat pump is already working near its design limit on a 100°F day; when the mercury hits 110°F or higher and the coil is clogged, the system can’t keep up and may shut down on high-pressure safety. Annual tune-ups help, but if your unit is already undersized for your home’s solar exposure, Santa Ana events will expose that weakness every time. Proper sizing and regular coil cleaning are the fixes.
Mini splits are ideal for second-story bedrooms in Chino Hills because they eliminate the ductwork problem entirely. Your existing central system’s cooled air travels through flex duct in a 140°F attic, warming up before it reaches your bedroom vents. A mini split head mounts directly in the bedroom and delivers conditioned air right where you need it, with SEER ratings often 30% higher than your old central system. For homes in the 91709 ZIP code with original R-22 equipment and failing attic ducts, we’ve found that a multi-zone mini split frequently pays for itself in comfort improvement alone.
