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 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:
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.

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.

Upon inspection of the system, we identified a water leak in the basement. The condensate pump was checked and found to be in need of replacement. Additionally, we discovered that the PVC drain was condensing water, which contributed to the leak. After cycling the system on cool, we found that the refrigerant pressures were normal, but there was a restriction on the suction side. Upon further investigation, we found that the filter was clogged, a common issue for clients with pets. We recommended replacing the filter at least once a month to prevent future issues. The clogged filter caused the indoor evaporator coil to freeze, which then thawed and caused water to drip into the blower compartment and onto the basement floor. We recommended either deep cleaning or replacing the indoor evaporator coil. The client will contact us again if problems persist.
Eugene was clear and straightforward. Very happy with him.


We meticulously rebuilt the condensate drain line, ensuring the correct pitch and secure connections. A properly configured P-trap was installed to prevent backflow. The condensate drain line was thoroughly blown out and cleared of obstructions. The evaporator coil was cleaned, and the condensate drain pan was deep cleaned, removing all debris. The secondary safety float switch was inspected and tested. Finally, we verified proper drainage and system operation.




I relocated the existing thermostat to the opposite side of the wall as per the homeowner's request. The original location caused nearby rooms to become excessively cold before the rest of the home reached the desired temperature. After gaining approval, I drilled through the adjacent wall for the thermostat relocation. The homeowner opted not to perform any wall patching or cosmetic repairs, as other wall repairs are already planned. I rerouted the existing thermostat wiring, sealed the original wall penetration to prevent air from the wall cavity from affecting the temperature sensor, and installed, wired, and tested the new Braeburn thermostat for proper operation. I verified normal system operation with a 20.4°F temperature split, confirming proper cooling performance. The new thermostat location will provide a more representative average temperature reading for improved comfort and more balanced cooling throughout the home.

Upon inspection, the 3-ton Infinity Series two-stage system with biometric damper was found to have a reduced airflow capacity of two tons. The system's air distribution was approximately 1,200 cfm, excluding the biometric damper. An error code indicated an inaccurate refrigerant charge, likely due to line restriction or overcharging. The system required a complete purge and recovery of existing refrigerant. I replaced the TXV and filter dryer, and recommended a deep cleaning of the furnace and coil. Further testing of refrigerant pressures was advised to determine if additional TXV and filter dryer replacements were necessary. Additionally, I suggested eliminating the zoning, biometric damper, and enlarging the return duct.


I successfully replaced the faulty capacitor in the unit. First, I safely discharged the unit to avoid any electrical hazards. I then removed the old capacitor, carefully noting its specifications for the replacement. After installing the new capacitor, I ensured all connections were secure and tested the unit to confirm proper functionality. The unit is now operating efficiently.




Upon arrival, the rooftop package unit was not responding to the thermostat's cooling call. After verifying the capacitor, contactor, and blower motor were functioning correctly, I independently energized the indoor blower to thaw the evaporator coil. Post-thaw, I recorded refrigerant pressures and jumped R to Y to start the compressor, which operated normally. However, suction pressure was low, and discharge pressure was high. Further inspection revealed a fallen baffle in the return air section, restricting airflow. After reinstalling the baffle and ensuring clean filters, the system was restarted. Despite normal compressor operation, refrigerant pressures remained abnormal, indicating a refrigerant leak.

The customer expressed interest in our heating and cooling services but wanted to discuss the options with their spouse before making a decision. I provided detailed information about our affordable solutions, including various models and features, and answered all their questions thoroughly. I left them with brochures and a contact number for further inquiries, ensuring they felt confident in their choice.
Ziv was very informative and helpful and explained that my unit, which I know is older, is quite inefficient and he gave me a quote for a new system (plus any permit fees that may be needed) and I accepted the offer and gave him a down payment. The price Ziv quoted was something I could manage. A previous HVAC contractor had told me a couple of years ago that a new system would be more than twice what Ziv quoted and that scared me to death! I appreciate honesty and integrity in the people I work with. Thank you
Jan Michael was a really nice guy! He was kind and patient with my 80 year old mother too who wants to know every little detail about what he was doing. He was friendly and took the time to explain everything he was doing. He was also very clean, well put together and he smelled good too. Mom and I were very impressed with him and we also appreciated how quickly and efficiently he solved our problem. Mom doesn't always trust or like repair men, but she liked Jan. If we could give Jan more than 5 stars we would. Great guy
Totally perfect service. Same day and responsive! our AC running cool now
Professional, felt trustworthy, pleasant efficient, knowledgeable
The installation team came, install the system and explain it to me. Very professional and friendly. What more can I ask ask?
Jeromy came on time, was polite and professional. He inspected the unit and explained clearly and with details how the system was running and what caused some condensed water to get out. He even performed a test with letting water run down the connected plastic pipe to prove it was not clogged. Thank you, Jeromy, and Affordable Heating and Air for always performing to high standards.
Good guys
I’ve had a couple problems over the last few years and one phone call to Ryan and everything is solved immediately. He is the most knowledgeable in the business. I have never met anyone who knows everything about everything, lol. The biggest factor for me is trust, and I trust Ryan 100%.
Edward Martinez was superb as is his style. I cannot say enough good about his work and outreach. How can l say more? Blessings to all. Ed.
