Chatsworth isn’t like Canoga Park or Woodland Hills. The Pacific marine layer never reaches here. Summer temperatures push past 105°F and stay there, and your system pays the price. We’re the company that shows up understanding that context, not discovering it after we’ve already misdiagnosed the problem.
Why Redwood Heating & Air San Diego Is Chatsworth’s Preferred Emergency & Commercial HVAC Company
Gregory Hahn founded this company and still leads every technical decision.

Our 428 verified reviews averaging 4.6 stars include dozens from Chatsworth homeowners who found us after other companies suggested replacing equipment that only needed duct repair.
We service your brand. Our technicians carry factory training and deep field experience across nine major HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That means we don’t show up, shrug at your older system, and push a full replacement because it’s the only thing we know how to sell.
Response time to Chatsworth averages under 90 minutes for emergency calls. We know Devonshire Street, Lassen Street, and the equestrian properties off Valley Circle Boulevard. We’ve worked on rooftop units at the commercial buildings along Topanga Canyon Boulevard and pulled emergency duty for the ranch homes tucked against the Santa Susana Pass.
13 years, 428+ reviews. That track record outlasts most local HVAC startups and one-truck operations that advertise emergency service but can’t staff it.
Our Emergency & Commercial HVAC Services in Chatsworth
24/7 Emergency HVAC
Chatsworth’s sustained peak-load summers don’t break equipment during business hours. Compressor failures happen at 7 PM on a Saturday when your system has been running nonstop since Tuesday. Our emergency line routes directly to Gregory Hahn’s team, not an answering service in another state. We stock capacitors, contactors, and refrigerant for the brands we see most in 91311: Goodman systems from the 1980s retrofits, Carrier and Bryant units installed in the 2000s, and newer Daikin mini-splits cooling detached barns and guest houses.
Commercial HVAC
From the retail strips along Devonshire to the industrial buildings near the 118 freeway, Chatsworth’s commercial properties need systems that survive Santa Ana wind events that load outdoor coils with debris and dry out components faster than neighboring Valley communities see. We service rooftop units, split systems, and packaged equipment for property managers who can’t afford tenant complaints or code violations. Our commercial clients get the same master-technician diagnosis that residential customers do. No junior techs learning on your equipment.
Rooftop Unit Service
Chatsworth’s commercial rooftops take a beating. The Santa Ana winds that funnel through the Santa Susana Pass don’t just rattle your sign, they force dust and debris through condenser fins at velocities that accelerate coil degradation. We clean, repair, and replace rooftop units with specific attention to this wind-loading pattern. We’ve found units in Chatsworth with coils that needed cleaning twice as often as identical equipment in Northridge, just 8 miles east.
Chiller Service
Commercial properties with process cooling or large-scale climate control rely on chillers that can’t go down in July. We handle chiller diagnostics, refrigerant management, and pump repairs for Chatsworth facilities that need sustained capacity, not band-aid fixes that fail under the next heat wave.
HVAC Inspection
Our HVAC inspection service in Chatsworth runs $80–$200 and focuses on the failure patterns this specific market produces: cracked attic flex duct, Santa Ana wind debris loading, and capacitor stress from sustained 105°F+ operation. We inspect distribution systems, not just equipment. Many Chatsworth homeowners come to us convinced they need a new AC when the real problem is ductwork bleeding cooled air into a 145°F attic.

Trusted Brands We Service in Chatsworth
We stock parts and carry deep training for Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Chatsworth customers, that means faster turnaround on repairs. We’re not waiting three days for a parts order because we didn’t recognize your 1995 Bryant condenser or your Daikin VRV system cooling a converted barn. From a single mini-split to a full commercial system, we service your brand with the right parts and the right expertise.
Common Emergency & Commercial HVAC Problems We See in Chatsworth Homes
- Attic flex duct cracked from decades of heat cycling. The 1980s retrofits in 91311 ranch homes used flex duct that degrades above 140°F. We regularly find segments split at can light penetrations, bleeding 30% or more of your cooled air into the attic. Homeowners blame the AC. The equipment runs fine. The distribution system is the culprit.
- Santa Ana wind debris loading outdoor coils. The Santa Susana Pass concentrates these winds through Chatsworth with above-average intensity. Condenser coils clog faster here than in West Hills or Woodland Hills, raising head pressure and accelerating compressor failure.
- Capacitor and contactor failure from sustained peak-load operation. Chatsworth’s evening heat retention means systems cycle less, run longer, and stress electrical components for weeks at a time. We replace more dual capacitors in August here than in any other month or market we serve.
- Hot rooms with no obvious duct blockage. The classic symptom of failed attic duct seals. Cooled air escapes before reaching the register. The room never gets comfortable. The thermostat keeps calling. The bill spikes. We trace these with airflow measurement and infrared inspection, not guesswork.

We arrived at a ranch home on Devonshire Street near the Santa Susana Pass where a 1988 Goodman split system was running nonstop but blowing warm air upstairs. The attic flex duct had cracked at every can light penetration, bleeding cooled air into the 145°F attic. We replaced the failed duct segments and added insulation, restoring airflow and cutting their utility bill spike significantly. The homeowner had already received a $6,200 replacement quote from another company. We fixed it for under $900.

FAQs — Emergency & Commercial HVAC in Chatsworth
Cracked attic flex duct is the most common cause in 91311 ranch homes. The original 1980s retrofits used flex duct that degrades in attics that bake above 140°F, and the seals fail at can light penetrations and joints. We measure airflow at each register and inspect attic runs with a camera to confirm. Call (844) 875-9451 for a free inspection — estimates are free.
Yes, significantly more than in neighboring Valley cities. The Santa Susana Pass funnels these winds through Chatsworth with concentrated force, loading condenser coils with debris and accelerating drying and wear on outdoor components. We recommend quarterly coil cleaning for Chatsworth commercial rooftops versus the standard biannual schedule elsewhere. Call (844) 875-9451 to set up a maintenance plan.
Repair if the compressor and coil are sound and the issue is electrical or duct-related; replace if you’re facing a compressor failure on R-22 equipment or if your attic duct needs full replacement anyway. In Chatsworth, we often see 1980s systems that need $1,200–$2,800 in duct repair but run another 8–10 years once distribution is fixed. We give honest numbers for both paths. Call (844) 875-9451 for an exact quote.
Yes. Chatsworth’s equestrian zoning means we regularly permit and install separate systems for detached structures, including mini-splits, heat pumps, and small packaged units. We handle the permit process with LA County and size equipment for the specific load, not guesswork. Call (844) 875-9451 to discuss your project.
Emergency service should be zero if your system is properly maintained; we recommend annual inspection and spring tune-up to prevent the failures that cause emergency calls. If you’re running a 1980s system in 91311 without recent duct inspection, schedule now before July heat arrives. Call (844) 875-9451 — estimates are free.
