AC Installation in Northridge, CA, Built for West Valley Summers
“Installed the new AC quickly same day when mine broke on the hot summer day what a lifesaver!”

David Dorfman, ⭐⭐⭐⭐⭐ Google Review


When to Replace an AC in Northridge
- The compressor has failed. That repair runs $3,200 – $4,800, about a third of what a new system costs.
- It uses R-22, a refrigerant no longer produced in the U.S., and it is leaking.
- You have paid for a repair in each of the last few summers and the next one is already showing.
- It runs from noon to dark in August and the house still sits above the temperature you set.
- Your LADWP bill jumps every summer, when the top rate tier costs more from June through September, while the house gets no cooler.

Planning an AC Installation in Northridge
Most single-family homes in Northridge are original or modified tract homes from the years after World War II, including the mid-1950s ranch houses around Devonshire Street and Tampa Avenue. Newer apartment and condominium complexes have filled in around CSUN. Many buildings were also repaired after the 1994 earthquake, so there is a wave of equipment here that is now about 30 years old. Three things shape most installations in Northridge:
- An older house. A 1950s ranch home has usually had more than one cooling system. We look at where the outdoor unit sits, how the refrigerant lines run and how the indoor unit drains, and the written quote spells out what is being replaced and what is staying.
- LADWP summer rates. Northridge gets its power from LADWP, and the top tier of the standard residential rate costs more from June through September. Your quote can include a standard system and an inverter heat pump side by side, so you can weigh the price against what each one costs to run in a west Valley summer.
- Electrical. Older homes often have an aging disconnect or wiring at the outdoor unit. If any of it has to be updated for the new equipment, that work appears in the written quote before you sign.
What your installation quote includes
- The building permit. Northridge is in the City of Los Angeles, so it comes from the Los Angeles Department of Building and Safety (LADBS). We pull it and schedule the inspection.
- Title 24 / HERS testing, which California requires when a system is replaced
- Removal and haul-away of the old equipment
- A 10-year manufacturer parts warranty with product registration, plus our 1-year labor warranty on the installation, extended to 2 years with a maintenance plan

Northridge AC Installation Questions
It depends on the home and the equipment, which is why we quote after an in-home visit. As a reference point, a complete 2.5-ton heat pump replacement with a matched air handler runs $11,200 – $15,000. Your written quote includes the LADBS permit, Title 24 / HERS testing and haul-away of the old equipment, and the estimate is free.
Yes. LADBS requires a mechanical permit for any installation or modification of a heating or cooling system in the City of Los Angeles, and Northridge is part of the city. We pull the permit, schedule the inspection and include both in your written quote, along with Title 24 / HERS testing.
A standard AC only cools and pairs with a furnace for heat. A heat pump cools the same way and also heats the house with electricity, which in Northridge comes from LADWP. We install both conventional systems and inverter heat pumps, and we can price the two side by side. See heat pump installation in Northridge.
