Super El Niño Alert
Super El Niño summer forecast: prolonged 100°+ heat waves headed for SoCal — tune up before your AC fails. Forecasters warn of a 55% spike in AC breakdowns this summer — book preventative service before the wait list grows. Last summer’s heat wave left thousands of SoCal homes without AC for 5+ days — don’t be next. Schedule now. Avoid a $3,000 emergency replacement — an $89 tune-up catches the failures heat waves expose. Grid stress + 95°+ days = capacitors and motors fail first. Get ahead of it — book your inspection today.

AC Tune-Up & Maintenance

longer system life — well-maintained units outlast neglected ones by half

Skip a tune-up and you're paying for it three different ways.

First in higher bills — a dirty coil, a low-on-charge system, or a clogged filter can add 15–30% to your monthly electric. Second in surprise breakdowns — most July emergency calls trace back to a small problem caught at a $179 tune-up the previous spring. Third in equipment life — a system serviced annually lasts 5–7 years longer than one that isn't.

An $179 spring tune-up usually pays for itself in energy savings alone by August. Everything else — fewer breakdowns, longer life, manufacturer warranty compliance — is bonus.

Why choose Canyon

What you actually get when you call us.

Lower monthly bills.

Clean coils, calibrated thermostat, proper refrigerant charge — these three things alone typically cut summer electric bills by 15–25%.

Catches problems early.

Most expensive AC failures (compressor, capacitor, blower motor) show subtle signs first. We catch them at the tune-up — when they're $80 fixes, not $2,800 ones.

Doubles system life.

A system maintained annually typically lasts 18–22 years. A neglected one is replaced at year 10–12. The tune-up cost over 20 years is a tiny fraction of one early replacement.

How it works

Four steps. No surprises.

Inspect

Compressor, capacitor, contactor, fan motor, evaporator coil, electrical connections, refrigerant level — all 22 checkpoints documented.

Clean

Condenser coil washed, condensate drain flushed, exterior cleared of debris, blower compartment vacuumed, new pleated filter installed.

Calibrate

Thermostat tested for accuracy, refrigerant verified to spec, airflow measured at the registers, electrical voltages confirmed.

Report

Full written service report with readings, photos, and any small issues we noticed — so you have the paper trail and a clear baseline.
