Signs your AC is struggling.
Puget Sound summers used to be mild enough to skip air conditioning. The last few heat waves changed that, and an undersized or failing system shows itself fast when the temperature spikes. A diagnostic visit tells you whether a repair will hold or whether replacement is the smarter call.
Schedule a diagnostic visit →Weak or warm airflow
Air moving through the vents that never gets properly cold.
Short-cycling
The unit starts and stops repeatedly instead of running a full cooling cycle.
Rising summer bills
A noticeable increase without any change in how you cool your home.
Losing ground in heat waves
A system that keeps up on a warm day but falls behind when temperatures spike.
Midea for AC-only installs, with a straight answer on the alternatives.
Midea
Our AC-only installations use Midea, backed by a 12-year parts warranty and a 4-year labor warranty in writing. Value-engineered cooling without a premium-brand markup.
Bosch
Midea builds the units sold under the Bosch name. If you've been quoted a Bosch system elsewhere, you're comparing the same equipment.
Heat Pumps
Want cooling and heating from one system? A Mitsubishi or Trane heat pump costs more upfront but carries a matched labor warranty of up to 12 years, and utility rebates can apply.
Warranty coverage in writing, on every tier we install.
AC-only installs carry a 12-year Midea parts warranty with 4 years of labor. Step up to a heat pump and the labor warranty matches the parts warranty, year for year.
No service charge on covered calls.
Big-brand installers advertise long warranties, then charge a $200 to $300 service fee every visit. We don't. If a covered issue comes up on a system that hasn't been neglected, the visit costs nothing.
| Brand | Parts | Labor |
|---|---|---|
| Midea | 12yrs | 4yrs |
| Trane / American Standard | 10yrs | 10yrs |
| Mitsubishi | 12yrs | 12yrs |
Sizing is the whole game with air conditioning.
An oversized AC short-cycles and never dries the air. An undersized one runs all day and still loses the heat wave. Mark and Vlad size every system to the home, and they're on every job.
From first call to cold air, in five steps.
AC-only installs don't earn rebates. Heat pumps do.
Straight answer: current PSE and Snohomish PUD rebate programs reward heat pumps, not air conditioners. A heat pump cools exactly like an AC and heats in winter, and the rebate can close much of the price gap. We'll run both numbers before you decide, and if you land on AC-only, that's a fine choice too.
