What Replacing a Chatsworth AC Usually Involves
Most Chatsworth homes are owner-occupied single-family houses, and many run on a split system: a condenser outside, and an indoor coil and air handler in the attic, a closet or the garage. Replacing it well means paying attention to both halves.
The outdoor unit
Larger lots and horse properties near the Santa Susana foothills put condensers close to dirt, hay and brush. We set the new unit on a level pad with clear space around it so the coil can breathe and stays easier to clean.
The indoor unit
A new outdoor unit is designed to work with a matched indoor coil, and pairing new equipment with an old coil is a common reason new systems underperform. Your quote spells out exactly which pieces are being replaced.
If the indoor unit is in the attic, a clogged condensate drain can put water through the ceiling. An overflow safety switch shuts the system off before that happens. If your installation needs one, it is listed in the quote.
Homes with two systems
Larger two-story homes sometimes have separate systems for upstairs and downstairs. They rarely fail at the same time, and replacing the older one first is often reasonable. We will tell you what we see in both.
Business parks
Chatsworth also has business parks and industrial buildings cooled by rooftop package units. We quote and install commercial rooftop equipment as well as residential systems.

Cost, Deposit and Payment
We quote every installation after a free in-home visit because equipment, access and electrical work differ from house to house. For reference, a complete 2.5-ton heat pump replacement with a matched air handler runs $11,200 – $15,000.
The deposit is the lesser of 10% or $1,000, the California limit for home improvement contracts, and the balance is due when the job is complete. We accept cash, check, Zelle and Venmo. Card payments carry a 3% surcharge.
Chatsworth is on LADWP, which bills its highest rates from June through September, the months when an efficient new system does the most for your bill.
Moving off R-22
R-22 production and import ended in the U.S. in 2020, so an R-22 system depends on a shrinking supply of reclaimed refrigerant. Replacing it ends that problem. New systems use lower-GWP refrigerants such as R-454B or R-32.

Chatsworth AC Installation FAQs
If one part has failed on an otherwise healthy system, repair it. If the compressor has failed ($3,200 – $4,800 to repair) or the system uses R-22 and is leaking, replacement usually makes more sense. We will put both options in writing.
