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.

Furnace Installation & Replacement

A warm home is one good install away.

is when most furnaces transition from worth-repairing to worth-replacing

Six signs it's time to upgrade — not just patch.

Your furnace is 15–20+ years old. You've paid for multiple repairs in recent seasons. Heating bills keep climbing. Some rooms are always cold. The pilot flame is yellow or flickering (a CO warning sign). Air feels excessively dusty or dry.

Modern condensing furnaces hit 96% AFUE+ — meaning 96 cents of every dollar of gas becomes heat in your home (vs. 70-80% for older units). That gap shows up on every gas bill, every month.

Why choose Canyon

What you actually get when you call us.

Up to 40% lower heating bills.

High-efficiency furnaces use significantly less gas for the same heat. Combined with available SoCal Gas rebates, payback periods are typically 5–8 years.

Safer combustion.

Modern sealed-combustion furnaces draw outdoor air for combustion and vent fully sealed flues — eliminating most CO risk associated with older atmospheric units.

Quieter, more even heat.

Variable-speed blowers and modulating burners deliver steady, even temperatures instead of the on-off blasts older furnaces are known for.

How it works

Four steps. No surprises.

Free assessment

We measure the home, check ducts, evaluate gas line and venting. Manual J load calc determines correct size — never guesswork.

Efficiency selection

We walk you through 80% / 90% / 96%+ AFUE options, identify SoCal Gas and federal rebates, and give you total cost of ownership over 10 years.
