Why Crestview Heating & Air California Is Claremont’s Preferred Emergency & Commercial HVAC Company
Our reputation in Claremont was built job by job, not through billboard ads. Owner Marcus Feldman serves as our Service Manager, which means the person answering your questions about a failed rooftop unit on Foothill Boulevard is the same person accountable for the fix. That structure matters when you’re managing a commercial property near the Claremont Colleges or a historic home in College Park.
250+ customers who left reviews agree: we maintain a 4.8-star average rating, and a significant share of that feedback comes from repeat calls in Claremont and neighboring cities. We’ve responded to enough emergency calls here to know that a compressor failure on a 105°F July afternoon isn’t just uncomfortable in this city, it’s urgent.
Our familiarity with Claremont’s specific conditions saves time on every call. We know which foothill homes north of Baseline Road run Goodman or Rheem equipment from the 1970s that’s now failing. We know the Village’s Spanish Colonial Revival properties have no ductwork. And we know the Colleges’ institutional buildings sometimes still operate gravity-fed steam heat that complicates any modern upgrade. That local knowledge means faster diagnosis and fewer return trips.
Our Emergency & Commercial HVAC Services in Claremont
24/7 Emergency HVAC
Claremont’s orographic heat effect makes emergency HVAC calls especially critical here. When temperatures spike 10°F above nearby Pomona during a Santa Ana event, a failed system isn’t a tomorrow problem. We take emergency calls for compressor failures, refrigerant leaks, electrical faults, and total system shutdowns across the 91711 ZIP code. Our team carries parts compatible with the nine major brands we service, so we’re not ordering components while your building bakes.
Commercial HVAC
Commercial properties in Claremont face a unique challenge: many buildings near the Claremont Colleges consortium blend historic architecture with modern occupancy demands. A department store on Indian Hill Boulevard needs different capacity planning than a 1920s campus building retrofitted with split systems. We size equipment for actual load, not generic square-footage rules, because Claremont’s heat pocket demands real capacity margin.
Rooftop Unit Service
Rooftop units are common on Claremont’s commercial buildings and larger custom homes, especially in the foothill neighborhoods. Original 1970s-era Goodman or Rheem RTU units in these areas were often undersized for the condenser load this city’s 110°F days create. We replace, retrofit, and maintain rooftop equipment with proper load calculations that account for Claremont’s specific thermal profile, not generic Inland Empire sizing.
Chiller Service
The Claremont Colleges’ older campus buildings, some dating to the early 1900s, frequently have gravity-fed or steam heat infrastructure. When a department upgrades to a modern split or VRF system, chiller integration requires careful engineering that most residential-only contractors have never encountered. We’ve handled these institutional retrofits. The complexity is essentially unique in this market.

Trusted Brands We Service in Claremont
Your system, our specialty. We service and stock parts for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Claremont, that range matters. A 1920s Village home might have a newer Lennox rooftop unit. A 1970s foothill custom home likely runs original Goodman or Rheem equipment. A College building upgrade might use Daikin VRF cassettes. We don’t tell you “we don’t work on that.” We show up with the right parts and the factory training to match.
Common Emergency & Commercial HVAC Problems We See in Claremont Homes
- Undersized condensers failing on 110°F days. In foothill custom homes north of Baseline Road, original 1970s-era Goodman or Rheem RTU units were never designed for Claremont’s documented heat pocket. When Santa Ana winds push temperatures to 105–110°F, these systems overload and fail. We see this every summer.
- Compressor burnout in ductless retrofits. Pre-war Craftsman bungalows near the Colleges have no ductwork. Poorly-installed window units or mini-splits create air-balancing issues that strain compressors. We’ve replaced more burned-out compressors in these homes than in any comparable city.
- Voltage spike damage to VRF systems. Santa Ana wind events cause sudden voltage fluctuations that damage sensitive inverter-driven equipment in upgraded institutional buildings. These aren’t standard electrical calls; they require emergency chiller or electrical service with specific VRF knowledge.
- Steam-to-modern integration failures. Many older homes in Claremont’s College Park district still rely on original gravity-fed steam radiators. Retrofitting to ductless mini-splits or VRF systems without understanding both antique steam and modern HVAC creates compatibility problems we regularly untangle.

FAQs — Emergency & Commercial HVAC in Claremont
They weren’t built for it. The Craftsman bungalows and Spanish Colonial Revival homes surrounding the Claremont Village were constructed in the early-to-mid 20th century without any ductwork. Adding central air means either extensive attic duct retrofits that compromise historic integrity, or careful mini-split placement that respects original architecture. We’ve done both. Call (844) 560-6978 for a free assessment of your specific home.
Not necessarily, but you need a contractor who understands institutional integration. Many Claremont Colleges buildings still operate gravity-fed or steam heat from the early 1900s. Upgrading to modern cooling without understanding that existing infrastructure creates compatibility failures. We evaluate the full system before recommending chiller, VRF, or split configurations. Call (844) 560-6978 to discuss your building’s specific steam or gravity-heat setup.
They stress it beyond design specifications. Santa Ana events deliver 90°F-plus temperatures in October and November with single-digit humidity, extending your cooling season and pushing thermal loads higher than equipment manufacturers size for in generic “Southern California” ratings. Rooftop units in Claremont’s heat pocket work harder and longer than identical units in cooler nearby cities. We size replacements with this margin in mind. Call (844) 560-6978 before your next Santa Ana season.
We service nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Claremont’s commercial and institutional properties, we most commonly encounter Trane and Lennox in newer installations, and Goodman or Rheem in original 1970s–1990s equipment. We stock parts and maintain factory-trained compatibility across all nine. Call (844) 560-6978 with your specific model number.
Yes, especially given Claremont’s thermal demands. A tune-up at $80–$200 catches refrigerant leaks, electrical wear, and condenser strain before they become $650 repairs or full replacements. For original 1970s Goodman or Rheem units north of Baseline Road, proactive maintenance often extends operational life through another brutal summer. We inspect with your system’s age and this city’s heat profile in mind. Call (844) 560-6978 to schedule.
