Yes, we are in Chatsworth. Our office is on Cozycroft Avenue, our trucks are stored here, and our technicians live in the San Fernando Valley. When you call for HVAC service in Chatsworth, your request isn’t sent to a dispatch center 2 hours away. We dispatch locally, right here in your city.
That local presence matters when your AC quits during a July heat wave, when your furnace won’t start on a January morning, or when smoke from a fire in the hills to the north raises quick questions about your indoor air.
Response time is faster, technicians know the neighborhoods and the housing stock, and follow-up service comes from the same team that performed the initial work.
Chatsworth service line: (818) 722-1332. Call anytime for 24/7 emergency dispatch.
Chatsworth is not a generic valley suburb. The northwest corner of the San Fernando Valley has its own combination of climate, housing stock, and infrastructure that determines HVAC service availability:
Extreme summer heat.
Chatsworth regularly experiences afternoons above 100°F, with July and August highs pushing 105°F or higher. The Santa Susana Mountains to the north trap heat in the basin. This means AC systems here log more cooling hours than most of the country and wear out faster.
Old tract homes with original ductwork.
Almost all of Chatsworth was built during the residential expansions of the 1960s and 1970s. Homes in neighborhoods like Winnetka Woods, Chatsworth Lake Manor, and Mason Avenue often have HVAC systems on their second or third replacement.
The ductwork and insulation, however, have never been updated. Equipment is modernized. Infrastructure that delivers conditioned air rarely does.
Wildfire smoke from the Santa Susana Mountains.
Chatsworth sits directly downwind of frequent brush fire activity. Post-smoke duct evaluation, filter upgrades, and coil cleaning are recurring calls after significant fire events in the mountains to the north and west.
Santa Ana wind conditions.
Strong seasonal winds bring dust and debris that load condenser coils, clog filters, and create airflow problems that homeowners often misdiagnose as equipment failure.
Chatsworth is our headquarters, so every service we offer is available here, often with faster response times than anywhere else we serve. Here is the full list:
Our team has completed HVAC repairs, replacements, and installations throughout Los Angeles County. View our local HVAC project portfolio to see examples of our work.
If you have owned a home in Chatsworth for more than a decade, you have probably replaced your AC unit. Here is why equipment struggles here specifically:
Our Chatsworth office operates a 24/7 emergency dispatch service. When your AC dies during a heat wave, when your furnace quits on a cold night, or when your CO detector alarms during winter, someone answers.
Response times depend on demand and location, but Chatsworth calls are usually the fastest because our office is here. During peak summer weeks, Care Club members get priority scheduling over non-members. This benefit often pays for itself the first time a July heat wave fills up the schedule.

Furnace repair and heating installation pick up from November through January.
The Los Angeles Department of Water and Power serves most of Chatsworth. LADWP current rebates of $1,000 to $1,250 per ton on qualifying ducted heat pumps, or $1,500 to $2,500 per ton on qualifying ductless mini-split systems that serve the entire home.
It also offers rebates of $100 to $120 per ton for qualifying standard AC installations. We handle rebate documentation for qualified installations. Verify current availability on our California HVAC Rebates page.
Diagnostic and service call: $95, credited toward any approved repair. Standard repairs range from $150 to $650. Major repairs (compressor, heat exchanger): $1,200 to $2,800 or more. AC tune-ups start at $69. Replacement costs vary by system type. We provide a written estimate after an in-home assessment.
Yes. Many Chatsworth homes from the 1960s and 1970s have original or deteriorated ductwork that undermines HVAC performance. We evaluate ducts during every AC installation, tune-up, and IAQ assessment. When ducts need work, we handle duct repair, sealing, or replacement as part of the project.
Yes. Wildfire smoke deposits ash on condenser coils, clogs filters, and settles in ductwork, where it recirculates for months. After significant fire events, we recommend coil cleaning, filter evaluation, duct cleaning, and MERV 13 filter compatibility. Chatsworth’s proximity to the Santa Susana Mountains is a concern.
Yes. Our Chatsworth office serves the broader San Fernando Valley and Los Angeles County. This includes Northridge, Porter Ranch, West Hills, Granada Hills, Woodland Hills, Van Nuys, Encino, Glendale, and beyond. Ventura County service is provided through our Simi Valley branch at (805) 755-4074.

Mauricio was incredibly helpful and did a great job. He knows his stuff and a great personality!
Upon inspection, I identified a refrigerant leak in the condenser coil of the air conditioning system. The leak was traced to a small puncture in the coil. I safely evacuated the remaining refrigerant and repaired the puncture using specialized tools and materials. After ensuring the repair was secure, I recharged the system with the appropriate amount of R-22 refrigerant. The system was then tested to confirm proper operation and no further leaks.
Completed
Payment was made via credit card, with a 3.5% fee, totaling $936 for the completed job. The task involved a temporary repair, akin to applying a Band-Aid, rather than a permanent solution. The system in question was an 8-year-old unit. Upon inspection, a refrigerant leak was identified as the primary issue. The payment structure included a 50% deposit upfront and the remaining 50% upon completion of the work. The repair addressed the leak, ensuring the system's temporary functionality was restored. However, it is important to note that this is not a long-term fix and further attention may be required in the future.
Well done
During the inspection, both HVAC systems were confirmed to be operating properly. However, several maintenance concerns were identified. For the 5-ton Daikin system, the ductwork had excessive dust and debris, and the outdoor condenser coil was dirty. The condensate drain line was shared with another system, and additional overflow protection was recommended. For the 2-ton heat pump, the condensate pump discharged into the 5-ton system’s drain line, and the emergency drain pan lacked an overflow safety switch. The air ducts and outdoor condenser coil also required cleaning. Recommendations include reconfiguring the condensate drainage, installing overflow safety switches, performing professional duct cleaning, and cleaning the condenser coils.
It was informative, quick, courteous .
I responded to a furnace issue where it attempted to start but shut down. The furnace, a Goodman GMS80703AXA, showed the inducer operating and the hot surface igniter glowing. The igniter measured 57.99 Ω, and the gas valve’s local switch was ON. Despite 27 VAC at the gas valve and steady inlet gas pressure, no gas flow was detected at the valve outlet. Consequently, the burners did not ignite, preventing the heating cycle from completing. The gas valve is likely faulty and needs repair.
Warranty completed
replace thermostat
Upon arrival, I identified a four-year-old furnace that had been red-tagged by the gas company. The issue was related to the mixing of unconditioned and conditioned spaces. The return air intake could potentially draw in unconditioned air, risking carbon monoxide contamination. Additionally, negative static pressure could pull natural gas into the conditioned space. I recommended sealing the return cavity, weatherproofing the return grill, and installing duct board inside the furnace to ensure only conditioned air is introduced.
Upon arrival, I found a 2016 3-ton Package Unit that was not turning on. After a thorough inspection, I discovered that the thermostat was difficult to operate, requiring significant pressure to change cycling modes. I tested both heating and air conditioning functions, which were operational during the service. However, temperature checks revealed high temperatures for heating and very low temperatures for cooling, indicating a lack of airflow. The return air duct, measuring 14x24, showed that the system was operating at about 50% capacity. Considering the system's age, I recommended proactive measures, including a potential replacement with a new gas-electric or all-electric option, especially given the customer's solar setup and state requirements by 2030.
I installed the Scorpion HX15 UVC-LED disinfection system in your HVAC unit. This robust system is designed for residential use, effectively killing mold, mildew, bacteria, and other harmful growths on the evaporator coil and surrounding areas. With its 30,000-hour lifespan and integrated air flow sensor, it lasts up to five times longer than traditional UV bulbs. It also reduces musty odors and prevents drain line clogs. I ensured your system and air quality are safe by blowing out the condensation line. 50% deposit required, with a 30-day labor warranty.
Fast and efficient. Excellent service.
