AC Installation & Replacement · Downey & Greater LA
A new AC, installed like a science.
We measure, we don't guess. Every installation starts with a Manual J load calculation and ends with commissioning and a city inspection — so your new high-efficiency system actually delivers what the label promises, for 15+ years.

Signs it's time to replace, not repair
If two or more of these sound familiar, a replacement conversation is worth having. We'll give you the honest math either way — see our approach to AC repair first if you're unsure.
It's 12–15+ years old
Compressors and coils wear out; efficiency drops every year. New SEER2 systems use dramatically less energy.
It runs on R-22 refrigerant
R-22 is phased out, making every leak repair harder to justify. Modern refrigerants end that problem.
Repairs keep stacking up
When you're calling every season, the repair money is better invested in equipment that won't quit.
Rooms never even out
Chronic hot and cold spots often trace to a mis-sized system or ductwork — both fixable at replacement time.
The house feels sticky
Poor humidity control is classic oversizing. A properly sized variable-speed system fixes comfort, not just temperature.
It's loud enough to notice
Modern variable-speed condensers run at a fraction of the sound level of decade-old equipment.
What's included in every installation
✓
Manual J load calculation — the system is sized to your home's real heat load, not the old label.
✓
Ductwork evaluation — leaks and restrictions found before they strangle your new system. See air duct services.
✓
Permit & city inspection — pulled, scheduled, and passed on our watch, with documentation for resale.
✓
Code-compliant install — new pad, whip, disconnect, line set flush or replacement, and proper drainage.
✓
Commissioning & balancing — refrigerant charge, static pressure, and airflow verified room by room.
✓
Haul-away & recycling — old equipment removed and refrigerant recovered per EPA rules.
From old to new in three steps
STEP 1
In-home assessment
We measure the home, inspect ducts and electrical, and listen to what bugs you about the current system.
STEP 2
Options in plain English
Good-better-best equipment options with efficiency ratings and trade-offs explained. You pick; we schedule.
STEP 3
Install day & walkthrough
Most swaps finish in one day. We commission the system, walk you through the thermostat, and leave it spotless.

Installation questions, answered
How long does an AC installation take?+
Most straightforward replacements are completed in a single day. Jobs that include duct modifications, electrical upgrades, or a switch to a heat pump may take two days. You'll know the timeline before we start.
What does "right-sized" actually mean?+
We perform a Manual J load calculation — measuring your home's square footage, insulation, windows, and orientation — instead of guessing from the old unit's label. Oversized systems short-cycle and dehumidify poorly; undersized ones never catch up.
Do you handle the permit and inspection?+
Yes. We pull the city permit, install to code, and coordinate the final inspection. You get documentation for your records and for resale.
Which brands do you install?+
We install Carrier, Trane, Lennox, Rheem, Goodman, Bryant, Daikin, Bosch, Mitsubishi Electric and more — and we'll recommend the best fit for your home and goals, not a house brand.
