Replacing your air conditioner is a big decision for your home. Choosing the wrong system can waste energy for years. If the installer cuts corners, you may end up paying more down the road.
But when you get the right equipment for your house, installed by a licensed team with all the paperwork handled, you get reliable comfort and lower bills from the start.
Affordable Heating and Air has been installing and replacing central air systems, heat pumps, and ductless mini-splits throughout Los Angeles County for over 20 years.
We take care of everything, from the first assessment to the Title 24 permit, HERS testing, LADWP rebate paperwork, and final checks. We make sure your system works properly before we leave.
If your old system breaks down and you need a quick solution, we offer same-day replacement.

The biggest mistake in AC installation is choosing the wrong size. If the system is too large, it turns on and off too often, causes humidity issues, and wears out sooner. If it is too small, it runs all day and never cools your home properly. Both options waste energy and money.
We start every installation with a Manual J load calculation.
This takes into account your home's size, insulation, window area and direction, ceiling height, duct condition, number of people living there, and heat from appliances.
For example, a home in Chatsworth with a south-facing living room and poor attic insulation needs a very different system than a shaded bungalow in Santa Monica, even if both homes are the same size.
We also check your current ductwork. If the ducts leak, are too small, or run through a very hot attic with old insulation, just installing new equipment will not fix your comfort issues. We will let you know before installation day if you need duct changes or better insulation.
The AC market has changed a lot in recent years. Now, Los Angeles homeowners can choose from several types of systems, each having its own benefits. It is no longer just about picking a brand of central AC.
Central air conditioning is the most common choice for homes that already have ductwork. New central systems with 15.2 SEER2 or higher are much more efficient than the older 10-12 SEER units still found in many Valley homes. If your ducts are in good shape, simply replacing your central AC is usually the most affordable way to improve your cooling.
A heat pump gives you both cooling and heating from one outdoor unit, so you do not need a separate gas furnace. In LA’s mild climate, heat pumps work all year round very efficiently. LADWP offers $1,000 to $1,250 per ton for qualifying central ducted heat pumps.
A qualifying four-ton central ducted system at the highest ducted tier could receive up to $5,000. A qualifying four-ton ductless system at the highest ductless tier could receive up to $10,000 if it meets LADWP’s entire-home service requirement, subject to program approval.
Ductless mini-splits are great for homes without existing ductwork, room additions, converted garages, ADUs, or any space where adding ducts is not practical. Mini-splits let you control the temperature in each area, are very efficient, and run quietly. Learn about ductless installation.
We set up every system with your thermostat, including smart options like Nest, Ecobee, and others. We handle the scheduling, check that heat pump modes work correctly, and set up SCE or LADWP time-of-use rate features so your system runs efficiently from day one.
We want you to know what to expect. Here is what a typical installation looks like:
01
Before we arrive, you have already received a written estimate with the exact equipment, scope of work, permit costs, and total price. We confirm the installation date and arrival window.
02
We arrive in the morning, protect your floors and work areas, and then remove the old equipment. We check the line set, electrical connections, and drain routing for any problems that need fixing.
03
During installation, we set the new outdoor condenser or heat pump, connect the indoor coil or air handler, pressurize, braze, and test the refrigerant lines for leaks, connect the electrical, and make sure the condensate line is working properly. For heat pump installations, we test both heating and cooling modes.
04
For commissioning, we measure airflow at every register, check the refrigerant charge against the manufacturer’s specifications (not just by feel), calibrate the thermostat, and run a full heating and cooling cycle. We show you the temperature split numbers before we leave.
05
For permits and paperwork, we take care of the Title 24 permit application, schedule HERS testing if needed, and submit rebate paperwork for qualifying LADWP, SCE, or SoCalGas programs for you.
Most standard replacements are finished in one day. More complex projects, like duct modifications, electrical panel upgrades, or multi-zone ductless installations, may take up to two days.

Replacing AC systems in the San Fernando Valley is not always simple. Homes in Chatsworth, Woodland Hills, Granada Hills, Northridge, Encino, West Hills, and Santa Clarita have unique conditions that affect how a new system should be chosen:
Our Simi Valley branch at (805) 755-4074 offers the same installation services throughout Ventura County. Simi Valley and Thousand Oaks experience inland heat similar to the San Fernando Valley.
Coastal communities like Oxnard, Ventura, Port Hueneme, and Camarillo need condenser units that can handle salt air, so we use corrosion-resistant coil coatings for these installations when needed.

SEER2 is the current efficiency standard. California requires a minimum of 14.3 SEER2 for new AC installations. Central ducted rebates begin at 15.2 SEER2 / 7.7 HSPF2 and reach $1,250 per ton at 19.6 SEER2 / 8.9 HSPF2. Ductless rebates begin at 15.2 SEER2 / 7.8 HSPF2 and reach $2,500 per ton at 20.5 SEER2 / 9.1 HSPF2; mini-split and multi-split systems must serve the entire home.
Title 24 — California’s Building Energy Efficiency Standards — applies to all permitted AC replacements. Requirements vary by climate zone and project scope. We handle permit applications, documentation, and HERS testing coordination as part of every installation.
Rebate availability changes. The federal IRA Section 25C tax credit expired December 31, 2025. TECH Clean California single-family rebates are fully reserved. HEEHRA rebates are fully reserved (waitlist only). LADWP, SCE, and SoCalGas utility rebates remain the primary active programs for 2026.

It depends on scope. A simple changeout where the ductwork and electrical service are already sound moves faster than a project involving duct modifications, an electrical panel upgrade, or a multi-zone ductless system.
Every installation includes equipment removal, installation, commissioning, and thermostat setup. We confirm the expected schedule during the in-home assessment so you know what to plan for before installation day.
AC replacements in Los Angeles County generally require a building permit and Title 24 compliance documentation, and some project scopes also require field verification testing. Affordable Heating and Air handles the permit application and coordinates field verification testing for our installations.
A full system replacement typically runs $9,000 to $22,000, with most Los Angeles projects landing between $11,000 and $13,000. A coil-and-condenser replacement can start around $6,000 when the existing furnace and ductwork are in good condition.
Ductless mini-split installations range from about $3,000 for a single zone to $15,000 for multi-zone systems. LADWP rebates on qualifying equipment reduce the net cost, and we provide a written itemized estimate after an in-home assessment.
California requires a minimum of 14.3 SEER2. Systems in the 16 to 20 SEER2 range typically offer the best balance of upfront cost and long-term energy savings for Los Angeles homes. LADWP rebates scale with efficiency — higher SEER2 qualifies for higher per-ton rebates up to 20.5 SEER2.
For many Los Angeles homes, a heat pump is worth serious consideration. It provides both heating and cooling from a single system and qualifies for the largest available LADWP rebates. Because LA winters are mild, a heat pump operates within its efficient range for most of the year.
How that translates into your utility costs depends on your rate plan, your usage, and the efficiency of the equipment it replaces — we walk through that comparison with you before you decide.
