Pick a time. We will be there.

It depends on more than square footage. Ceiling height, sun exposure, insulation, windows and occupants all change the load. As a Phoenix-area starting point, plan on about 1 ton per 500 to 600 square feet, then use our calculator or book a free load calculation for a firm answer. Oversized systems cool fast but leave the air clammy and wear out sooner.

Same-day service is available for most repair calls booked before 2 p.m. Emergency calls are dispatched around the clock and our average arrival time across the East Valley is 90 minutes. Total Care members are guaranteed a technician within four hours.

Replacement estimates are free and include a load calculation and duct inspection. Repair diagnostics are $89, and that fee is credited toward the repair if you go ahead.

Most single-system replacements take one day, and larger homes with duct changes take two. We protect floors, haul away the old equipment and run a full start-up and airflow test before we leave.

We offer 0 percent financing for 18 months on approved credit and low fixed-rate terms up to 10 years. You will also see utility rebates from APS and SRP applied to the quote, typically $300 to $1,200 on high-efficiency systems.

Twice a year. Run time here is roughly double the national average, so dust, capacitor wear and drain-line growth show up fast. A spring tune-up before April and a fall check before the mild season keep most failures from happening in July.

If your system is more than five years old, almost always. A Comfort plan costs about what one capacitor replacement does, and members skip the diagnostic fee and the emergency queue.
