is when most ACs start costing more to keep than to replace
Six signs it's time to stop repairing and start replacing.
Your system is 12–15+ years old. Repair costs are crossing 50% of a new unit. Bills have crept up year after year. You're calling for service every season. The system uses R-22 (banned). And no matter what you do, the upstairs is never quite comfortable.
If two or more of those describe your system, replacement usually pays for itself faster than the next round of repairs. We give you the real math before you commit — no pressure, no upsell.
What you actually get when you call us.
Up to 40% lower bills.
Modern high-SEER systems use far less electricity for the same cooling. The savings start on bill #1 and continue every month for the life of the system.
Real comfort, every room.
We don't just swap the box — we size with a Manual J load calc, check static pressure, and address airflow problems so the system actually delivers what it promises.
Backed by warranty + workmanship guarantee.
Manufacturer parts warranty (typically 10 years) plus our written workmanship guarantee on every install. If something isn't right, we make it right.
Four steps. No surprises.
Free in-home assessment
We measure, look at ductwork, check insulation, ask how you actually use the home. No pressure visit.
System selection
We recommend the right size and brand from Carrier, Trane, Lennox, and others — matched to your budget and rebate eligibility.
Professional install
Old unit removed, new unit installed, electrical, refrigerant, condensate — all in one day for most homes. No subcontractors.
Test & walkthrough
Full commissioning, refrigerant verification, performance test. We walk you through your new thermostat and warranty paperwork.
AC Installation & Replacement: questions homeowners ask us most.
The honest, in-plain-English answers we’d give a neighbor calling on the phone.
How long does a full AC replacement take?
Most single-system swap-outs in the San Gabriel Valley finish in a single day — old unit out, new unit in, refrigerant charged, system commissioned, and walkthrough done before dinner. Heat pump conversions, dual-system homes, or major duct repairs may add a second day.
What does a new AC system cost in Glendora?
For a typical 3-ton single-system home, complete installs run roughly $7,500 to $14,000 depending on SEER rating, brand, and whether ductwork needs work. We give you a free in-home assessment with a written quote — no pressure, no “today only” pricing games.
Do you offer financing on new AC installs?
Yes — $0 down and 0% APR promotional plans are available with approved credit through our GreenSky® partnership. Credit limits up to $100,000. See our financing page for current plan details and disclosures.
What brands do you install?
We’re a Trane Comfort Specialist™ dealer, and we also install Carrier, Lennox, Goodman, Rheem, and Mitsubishi mini-splits. The right brand depends on your home, budget, and rebate eligibility — we’ll explain the trade-offs in plain English.
Are there rebates or tax credits available?
Often, yes. The federal Inflation Reduction Act offers up to $2,000 in tax credits on qualifying heat pump installs, and SCE / SoCalGas regularly run rebates on high-efficiency equipment. We handle the rebate paperwork as part of the install — not something you have to chase yourself.
