Why Crestview Heating & Air California Is Commerce’s Preferred AC Repair & Installation Company
Commerce isn’t a typical residential HVAC market, and we don’t treat it like one. Owner Marcus Feldman serves as our Service Manager, which means when a warehouse on Telegraph Road calls at 2 a.m. with a failed compressor, the person overseeing the repair has direct ownership stake in getting it right — not a dispatcher reading from a script.
Our 4.8-star average across 250+ customer reviews reflects real performance on real equipment: 15-ton package units, heat-stressed mini splits in converted office spaces, and legacy split systems in those scattered post-WWII homes near East Washington Boulevard. We’ve built that reputation by showing up with factory-trained knowledge across nine major brands and the parts inventory to match.
Response time to Commerce matters differently here than in residential cities. A rooftop unit failure at a 24/7 distribution center isn’t a comfort issue — it’s a production shutdown. We structure our emergency capacity around that reality.
Our local knowledge runs deep. We know which buildings on Randolph Street have the old tar-and-gravel roofs that pool water around unit bases. We know the particulate loading from I-710 truck traffic means coil cleaning intervals should be cut by a third. And we know the voltage sag patterns from heavy industrial equipment that fry capacitors on aging compressors.
Our AC Repair & Installation Services in Commerce
AC Repair
Commerce’s industrial environment punishes air conditioning equipment harder than almost anywhere in Los Angeles County. Diesel particulate from the I-5 and I-710 corridors clogs condenser coils with a stubborn, oily grime that standard residential cleaning won’t touch. We see high head pressure failures and compressor burnout on older units without eco-coated coils — especially in buildings east of the freeway interchange where truck density peaks. Our AC repair service in Commerce starts with thorough coil inspection and cleaning, electrical testing for capacitor health, and refrigerant level verification. Most repairs run $150–$650, with same-day response for critical failures.
AC Installation
New AC installation in Commerce means commercial rooftop package units for tilt-up concrete warehouses, not suburban split systems. We size equipment for the amplified cooling loads created by dark industrial rooftops and surrounding asphalt logistics yards — loads that can run 10–15% higher than equivalent square footage in residential Montebello or Pico Rivera. Our installations range from $3,500 for smaller commercial split systems to $7,500 for full rooftop package units on mid-size warehouses. We handle crane coordination, curb adapters, and the structural assessments that tilt-up buildings require.
AC Replacement
Replacing a rooftop unit in Commerce involves more than swapping boxes. Many buildings here have legacy R-22 systems that need full refrigerant line replacement or conversion. The city’s intense heat island effect means we spec higher efficiency tiers than minimum code — the extra SEER rating pays back fast when your unit runs 16 hours daily through July and August. We evaluate whether your existing ductwork and electrical service can handle modern capacity requirements, particularly in converted industrial spaces where original systems were undersized for current use.
Refrigerant Recharge
Low refrigerant in Commerce usually signals a leak, not normal consumption. The vibration from heavy rooftop units, thermal cycling from extreme heat, and corrosion from pooled water on tar-and-gravel roofs all create leak points. We pressure-test with nitrogen, locate leaks with electronic detection, and repair before recharging — never just top off and walk away. A proper recharge with leak repair runs $150–$650 depending on system size and refrigerant type. R-410A and the newer R-32 require different handling protocols, and we stock both for Commerce’s mixed-equipment inventory.
Capacitor Replacement
Voltage fluctuations from heavy industrial equipment across Commerce cause premature capacitor failure — one of the most common service calls we handle. A failing capacitor makes your compressor hard-start, draws excess amperage, and eventually burns out the motor entirely. We test capacitance, check for bulging or leaking, and replace with OEM-grade components rated for the local electrical environment. It’s a $150–$400 repair that prevents $2,000+ compressor replacement.
Compressor Repair
Compressor failure is the big one, especially on older rooftop units running at capacity through Commerce’s extended hot season. We were called to a warehouse on Randolph Street where a 15-ton Carrier package unit had lost all cooling due to a failed compressor. The compressor was still under warranty, but the labor and refrigerant recharge cost $1,200. We had the unit back online by 4 a.m., saving the shift from heat-related downtime. Not every compressor can be repaired — locked rotors, burnt windings, or repeated failures on 20-year-old units usually mean replacement — but we evaluate honestly rather than defaulting to the most expensive option.

Trusted Brands We Service in Commerce
We maintain factory-trained compatibility and active parts inventory for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Commerce, that means we can source compressors for legacy Carrier package units, control boards for Trane Voyager series, and coils for Goodman commercial splits without the week-long delays that shut down operations. We stock high-turnover components — capacitors, contactors, filters sized for particulate-heavy environments — in our service vehicles for same-day resolution. Your system, our specialty: we don’t turn away equipment because of brand.
Common AC Repair & Installation Problems We See in Commerce
- Diesel particulate fouling on condenser coils. The I-5 and I-710 corridors generate relentless particulate loading that coats coils with oily, hydrophobic grime. Standard residential cleaning methods won’t remove it. We see high head pressure, reduced capacity, and eventual compressor failure on units that haven’t been properly maintained.
- Voltage fluctuation damage to capacitors and contactors. Heavy industrial equipment across Commerce creates electrical sag and surge patterns that residential neighborhoods don’t experience. Capacitors fail early, contactors pit and weld, and compressors start hard — a cascade that starts with a $200 part and ends with a $3,000 motor.
- Water pooling and cabinet corrosion on flat roofs. Tar-and-gravel roofs without proper curbs or drainage let water collect around unit bases. Rust penetrates cabinets, shorts control boards, and destroys electrical connections. We’ve replaced entire units where preventive curb work would have saved thousands.
- Undersized equipment for converted industrial spaces. Warehouses converted to office or light manufacturing often reuse original HVAC sizing that assumed open storage, not heat-generating equipment and occupancy loads. The result is units that run continuously, fail prematurely, and never achieve comfortable conditions.

FAQs — AC Repair & Installation in Commerce
Yes. We maintain 24-hour emergency response specifically for Commerce’s round-the-clock industrial operations. A rooftop unit failure at 2 a.m. in July can shut down a distribution center, causing thousands in lost productivity; after-hours emergency response is a must in this market. Our Service Manager, Marcus Feldman, personally oversees night dispatch to ensure the technician arriving at your facility has the right parts and authority to make repair decisions on site. Call (844) 560-6978 anytime — estimates are free even for emergency calls.
Every 60–90 days during peak operation, not the standard 6-month interval. Commerce’s location between the I-5 and I-710 corridors creates diesel particulate loading that would be extreme by any standard — oily, hydrophobic grime that standard residential cleaning won’t remove. The South Coast Air Basin smog layer amplifies this year-round. Units without eco-coated coils need the most frequent attention; we’ve seen compressors fail in a single season when maintenance was deferred. We offer scheduled maintenance plans calibrated to this accelerated cycle.
Replace it, in most cases. A 20-year-old unit in Commerce has endured roughly 300,000 operating hours in one of California’s most punishing thermal and particulate environments. Repair costs on legacy R-22 equipment — refrigerant that now costs $80+ per pound and is increasingly unavailable — quickly approach replacement economics. We evaluate current repair cost against replacement, factor available utility rebates for high-efficiency equipment, and calculate payback from reduced energy consumption. When repair exceeds 40% of replacement cost, we recommend new equipment. Call (844) 560-6978 for a specific analysis of your unit.
We service all nine major brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Commerce’s commercial market, Carrier and Trane rooftop package units dominate older installations, while Goodman and Rheem appear frequently in newer tilt-up construction. We maintain factory training and active parts inventory for all nine, so we’re never in the position of telling a facility manager “we don’t work on that.” Our service vehicles carry high-turnover components for the brands most common in this market.
Yes. Tilt-up construction is standard in Commerce, and we’ve installed hundreds of units on these buildings. The process requires structural assessment of roof load capacity, proper curb installation with drainage to prevent the water pooling that destroys cabinets, and crane coordination for units over 5 tons. We handle permits, electrical service upgrades when needed, and the curb adapters that mate new equipment to existing ductwork. Most tilt-up installations in Commerce run $3,500–$7,500 depending on unit tonnage and access complexity. Call (844) 560-6978 to schedule a site evaluation.
