A proper AC service visit checks your whole cooling system, not just the outdoor unit. Our technicians look at how the system is working, find out why comfort problems are happening, and make sure your equipment is safe, efficient, and ready for the Los Angeles heat.
Our air conditioning services include AC diagnostics and troubleshooting, emergency AC repair, seasonal AC tune-ups, cooling system maintenance, central air and ductless mini-split service, heat pump cooling support, thermostat and smart thermostat checks, airflow and duct performance evaluation, filter and indoor air quality recommendations, and repair-versus-replacement guidance.
If your system needs a specific repair, visit our AC Repair page. For planned seasonal service, visit AC Tune-Up. If your system is older or no longer worth repairing, visit AC Installation.
Los Angeles AC systems encounter more than normal summer use. Homes across the San Fernando Valley, Greater LA, and surrounding communities contend with extended heat waves, attic heat gain, older ductwork, wildfire smoke infiltration, and cooling equipment that runs for six to eight months per year.
A neglected system can cause weak airflow, higher utility bills, uneven room temperatures, frozen coils, water leaks, and eventually an emergency breakdown on the hottest day of the year, when every HVAC company in the Valley is already booked.
Regular AC service catches small problems before they become expensive repairs. It also helps your technician determine whether your issue is simple maintenance, an airflow or duct problem, a thermostat misconfiguration, or an aging system that should be replaced rather than repaired again.
The San Fernando Valley is especially hard on cooling systems. Homes in Chatsworth, Woodland Hills, Granada Hills, Northridge, Encino, and West Hills deal with hotter afternoons, strong sun exposure, and attic temperatures that push the AC to run longer and harder than it was designed for.
Long heat waves cause extended run times, compressor strain, and weak cooling. An AC service visit checks refrigerant quantities, airflow, coils, and electrical components for signs of heat-cycle stress.
Hot attics trap heat above the living space and bake ductwork, reducing the temperature of air delivered to rooms below. A technician reviews duct condition, insulation levels, and cooling load to determine whether the problem is the equipment or the building.
Older homes across the Valley and Greater LA often have leaky ducts, undersized returns, and airflow restrictions. According to ENERGY STAR, 20 to 30 percent of conditioned air can be lost through duct leaks, holes, and poor connections. No equipment upgrade can fix this problem unless the ducts are fixed first.
Wildfire smoke clogs filters and coats condenser coils faster than normal dust. After any significant smoke event, a service visit should include a filter check, coil inspection, and a review of whether your system can safely support a higher-MERV filter.
Los Angeles County is the primary focus of this page, but Affordable Heating and Air also serves Ventura County through our Simi Valley branch at (805) 755-4074.
Ventura County homes face different AC challenges depending on location. Simi Valley and Thousand Oaks deal with inland heat cycles and long cooling demand, similar to the San Fernando Valley. Coastal communities like Oxnard, Ventura, Port Hueneme, and Camarillo need extra attention to outdoor condenser coils because salt air and marine exposure speed up corrosion. We offer special maintenance for these areas, including annual epoxy coil coating for high-exposure installations.

Call for service if your system is no longer cooling the way it should, even if it still turns on. Many AC problems start small before they become emergencies.
You might notice warm air from the vents, weak or uneven airflow, the system running longer than before, a sudden jump in energy bills, or loud buzzing, rattling, grinding, or humming.
Other signs include burning, musty, or electrical smells, water collecting around the indoor unit, ice on the evaporator coil or refrigerant lines, the thermostat reading not matching the room temperature, rooms that never cool evenly, or dust, smoke smell, or poor air quality when the fan is on.
If your AC stops working during a heat wave, call for emergency service immediately. If the system still runs but feels weak, schedule a diagnostic or tune-up before the problem compounds.
Call (818) 722-1332 for AC Service in LA and 8057554074 in Ventura County.
A professional AC service visit inspects the entire cooling system, including both the visible parts and the performance issues that affect comfort and operation.
Our technicians check thermostat operation and settings, air filter condition and fit, indoor evaporator coil condition, outdoor condenser coil condition, refrigerant level and cooling performance, electrical connections, capacitors, contactors, and safety controls, blower motor and fan operation, condensate line line, airflow at supply and return vents, duct leakage or restriction indicators, unusual vibration or noise, system cycling pattern, temperature split and comfort performance, and smart thermostat or zoning setup.
After the inspection, you get clear next steps. We explain what is urgent, what can wait, what might improve efficiency, and when replacement may be better than another repair. Everything is documented, and no work is done without your approval.
Many homeowners search for “AC service” when they are not sure what they actually need. The right solution depends on what the system is doing, how old it is, and whether the problem is minor, recurring, or expensive.
Seasonal care and the system still works: Schedule an AC tune-up before summer or after heavy use. This is a preventive service, not a repair.
If your system has a specific problem, such as warm air, strange sounds, leaks, short cycling, or a failed component, visit our AC repair page for diagnostic and repair service.
If your system is old, inefficient, or unreliable, with regular repairs, rising bills, poor comfort, or outdated equipment, visit our AC installation page for replacement guidance and rebate information.
If the air appears dusty, smoky, or stale, you may have a filter, duct, or ventilation issue. Visit our Indoor Air Quality or Air Duct Cleaning pages.
If rooms stay hot even when the AC is running hard, it is likely an insulation, duct, or system sizing issue. Visit our Insulation Services page or ask about an airflow and load assessment.
Repair is often the right call when the system is newer, the issue is isolated, and the cost is reasonable. Replacement makes more sense when the system is older, breaks down frequently, uses outdated components, struggles during normal heat, or has efficiency problems that repairs cannot solve.
Consider replacement if the system is over 15 years old, repair costs are close to half the price of a new unit, the AC runs all day during normal summer heat without reaching the set temperature, parts are getting harder to find, or the system still uses R-22 refrigerant. R-22 is now very expensive to recharge because of the EPA phase-out.
A technician should explain both options honestly. At Affordable Heating and Air, we use an objective scoring system that considers system age, repair cost, remaining useful life, energy savings potential, refrigerant type, and your long-term plans for the home. The numbers guide our recommendation, not a sales pitch.
LADWP currently offers rebates of up to $2,500 per ton on qualifying heat pump replacements, which can shift the repair-vs-replace math significantly. Compare potential efficiency savings with our SEER Energy Savings Calculator.

Air conditioning service in Los Angeles is inseparable from indoor air quality. Wildfire smoke, smog, dust, and pollen all circulate through your duct system and affect how your home feels when the AC is running.
During smoke events, a higher-efficiency filter, such as MERV 13 or the highest rating your system can safely support, helps reduce fine particles. However, not every system can handle a high-resistance filter without airflow problems. A technician checks filter size and fit, return duct performance, blower capacity, and whether duct cleaning or sealing may help before recommending a filter upgrade.

The HVAC system was significantly outdated, being 41 years old and using R-22 refrigerant. It had a long history of repairs, indicating severe wear and tear. After thorough inspection, it was determined that replacement was necessary. The old system was safely removed, and a new, energy-efficient unit was installed, ensuring optimal performance and reliability.
50% upon approval and 50% upon completion, with Zelle or card as accepted payment methods.
Upon arrival, I conducted a thorough diagnostic assessment of the system. After identifying a faulty capacitor, I carefully removed it and replaced it with a brand new, high-quality capacitor. This involved precise measurements and adherence to safety protocols to ensure the replacement was done correctly. I tested the system post-replacement to confirm that the new capacitor was functioning optimally and that the system was operating as intended. The job was completed efficiently, restoring the system's performance and reliability.
I conducted a thorough pre-engineering evaluation for a proposed HVAC system replacement. I verified the existing equipment, electrical service, ductwork, refrigerant line set, attic conditions, and installation requirements. The existing system includes a 2003 American Standard 3-ton R-22 condenser and a Carrier 60,000 BTU furnace. The line set will be pressure tested and reused if it passes, with deteriorated insulation replaced. The existing ductwork will remain, and new transitions/plenums will be fabricated. The thermostat wiring will be replaced for improved reliability. Installation will include a new disconnect, whip, secondary drain pan, SS2 safety switch, condensate drain blowout, and RSH-50 voltage monitor/surge protector. Final startup will involve airflow verification, refrigerant charging, system commissioning, and operational testing.
a 50% deposit upfront and the remaining 50% upon completion of the service. Payment will be made via check.
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
