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.

The most frequent service calls in Chatsworth are AC repair during summer (capacitor failures peak in July and August), AC tune-ups in spring, post-wildfire duct and coil cleaning after brush fire events, and AC replacement for systems reaching 15 to 20 years of age. 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.
If your AC has stopped working on a 105-degree afternoon, your furnace will not start on a cold morning, you have noticed higher energy bills, or you want to schedule a pre-summer tune-up, call the Chatsworth office, and we will take care of it.

Javier is great
I addressed a recurring power loss at the thermostat due to the auxiliary pan SS2 tripping from water accumulation. Despite extending the primary condensate breather and securing the secondary drain, water entered the auxiliary pan again within 24 hours. I recommended rebuilding the primary P-trap, clearing the drain line with nitrogen, and installing an SS2 at the secondary drain. I advised the homeowner to keep upstairs doors open during cooling and avoid low thermostat settings. Further inspection will be needed if issues persist.
Excellent service
I completed a 3-ton heat pump conversion, utilizing a LADWP rebate, valued at approximately $3,000. The project involved removing and disposing of existing equipment. I installed a Carrier Comfort 3-ton up to 15.2-18 SEER2 inverter heat pump condenser with R454B refrigerant, along with a 3-ton 36K BTU air handler unit. Electrical and gas connections were made, and a condensate line was blown out. The installation included a safety shut-off switch, thermostat, and necessary electrical and gas lines. The job was completed with a 10% deposit, 70% upon crew arrival, and 20% upon equipment start-up.
On October 21, I removed and hauled away all existing HVAC equipment. I then installed a new Carrier Comfort 2.5-ton inverter heat-pump condenser, ADP FAU 115V 3-ton furnace, 3-ton upflow evaporation coil, filter base, electrical power whip, disconnect box, condenser pad, FAU power cord, SS2 secondary safety switch, and Braeburn 2030 thermostat. I also performed a blow-out, reconnected the condensation drain line, flushed and reconnected the copper line set, pressure tested, and re-insulated the line set. Payment terms include a 10% deposit or $1000, 70% upon crew arrival, and 20% upon unit startup. Standard warranties include 1-year labor and 10-year parts and compressor warranties.
We installed a new AC Pro H-Series 27K BTU mini split system with a 4-zone condenser and two ceiling cassette air handlers. The system includes a new mini split line set, condensation line, bracket, power whip, and disconnect box. The outdoor condenser connects to an existing 220V electrical line. The job includes a regular crane, labor crew, permit, and HERS test fees. The system qualifies for at least $5,000 in LADWP rebates. Payment is 10% upon signature, 70% upon crew arrival, and 20% upon system start-up.
On Tuesday, I completed a comprehensive change-out of a GOODMAN 5 TON 14 SEER condenser and coil. The process began with the removal and disposal of the existing equipment. I then installed a new 5 TON 14 SEER condenser and a 5 TON plenum evaporator coil. An electrical service disconnect box and whip were also installed, followed by the blow-out of the existing condensation line. The existing drain pan was checked for proper drainage and leveling. A condenser pad, SS2 safety shut-off switch, and Braeburn thermostat were installed as needed. The AC line set was flushed with RX-11 or nitrogen. Connections were made to the existing electrical circuit, low voltage line, supply plenum, and air ducts. The job included GOODMAN standard warranties and adhered to the payment schedule.
We installed a 3-ton 36,000 BTU 18 SEER2 AC PRO H-Series Multi Zone Mini Split Heat Pump Condenser, a 3-ton 12,000 BTU AC PRO H-Series Air Handler, and an electrical whip. We also installed the electrical line, breaker, and line-sets, along with a condensation pump and line-set covers. We blew out the existing condensation line and provided labor. The job included a 10-year warranty and a 1-year labor warranty.
I meticulously performed a comprehensive Rotobrush mechanical cleaning on all accessible supply and return ductwork, removing accumulated dust, debris, pet hair, and contaminants from the duct interiors. I also cleaned accessible supply registers, return grilles, and duct openings. Following this, I conducted a thorough air handler deep cleaning and sealed the supply registers. I then reinstalled and secured all registers and grilles, inspecting accessible duct connections for any damage, loose joints, or air leakage. Finally, I verified the airflow and overall system operation to ensure optimal performance. Additionally, I provided a one-time disinfect and sanitization of the ductwork using advanced techniques and powerful disinfectants, effectively eliminating harmful bacteria, viruses, mold, and other contaminants for a clean, safe, and healthy airflow.
We carefully lifted and secured the existing 4-ton rooftop unit. A custom roof curb/transition assembly was installed, featuring an accessible return-air plenum. The existing return duct was reconnected, and an additional properly sized return-air duct and grille were installed. A new supply-air duct and register were added to enhance airflow distribution. The unit was reset, secured, weather-sealed, and reconnected. A compressor soft-start kit was installed, and we tested airflow, static pressure, temperature split, compressor startup amperage, and overall system operation. Roofing repairs beyond sealing the HVAC curb penetration were not included.
I meticulously gathered all necessary pictures and measurements for pre-job engineering, ensuring accuracy and completeness. I reviewed the scope of work in detail with Danny, the property manager, discussing each aspect thoroughly. This included confirming the project specifications, identifying potential challenges, and aligning on the timeline and resources required. My attention to detail and clear communication helped establish a solid foundation for the project, ensuring all parties were well-informed and prepared for the upcoming work.
I conducted a comprehensive heat pump conversion estimate, beginning with a thorough assessment of the existing HVAC system. This included evaluating the home's insulation, ductwork, and overall energy efficiency. I then analyzed various heat pump models to determine the most suitable options based on the client's needs and budget. Detailed calculations were performed to estimate installation costs, energy savings, and potential return on investment. The estimate also included a timeline for the conversion process and a breakdown of labor and material costs. Finally, I provided the client with a clear, itemized report, ensuring they understood each aspect of the proposed conversion.
Juan was very friendly and knowledgeable. He clearly explained how to operate the 4 A/C’s in the house and double checked everything to make sure there would be no failures moving forward. And he even decreased the service fee!! Great guy!
