Frequently Asked Questions

How Long Does HVAC System Replacement Take?

Most standard residential installations complete in one day. More complex homes or systems may require additional time, which we discuss with you during the planning stage.

Will I Be Without Heating or Cooling During Replacement?

There is a brief period when the old system is disconnected and the new one isn't yet operational. We coordinate timing carefully to minimize this disruption to your comfort.

Do I Need to Be Home During the Entire Installation?

It's helpful for someone to be available at the start and end of the appointment for questions and review. You do not need to be present throughout the entire process.

Common Questions

How do I know if I should repair or replace my AC system?

We use a simple framework we share with every customer facing this decision:

  • If the repair cost is less than 50% of a replacement and the system is under 10 years old, repair usually makes sense.
  • If the system is 12+ years old and facing a major repair, replacement often saves more money over 5 years.
  • If the system uses R-22 refrigerant (phased out in 2020), replacement is almost always the better path — R-22 is expensive and increasingly hard to source.

Keep in mind that Phoenix AC units run roughly 2,500–3,000 hours per year — two to three times the national average — so they age faster than their rated lifespan suggests.

We'll tell you which category your system falls into after the diagnostic, and we won't push you toward replacement if repair is the honest answer. You can also try our Repair or Replace calculator for a quick self-assessment.

Do you offer financing for larger repairs or replacements?

Yes — and we offer more financing options than most local companies. We partner with Goodleap, Service Finance, and Wisetack, giving you access to multiple lenders including options with 0% APR for qualified customers.

Whether you're replacing an AC system, installing a tankless water heater, or dealing with a sewer line repair, we can walk you through options before the work begins. When a Phoenix summer AC failure hits, cost shouldn't be the reason a problem goes unfixed.

Will you pull the required permits for the job?

Yes — always, for any work that requires one. Whether your home is in Phoenix, Scottsdale, Mesa, Chandler, or Gilbert, each city has its own permitting process — and we handle all of them.

Permits are required for HVAC replacements, water heater installations, gas line work, and sewer line repairs, among other jobs. We know some contractors skip permits to save time. Don't let them. Unpermitted work can become a serious problem when you sell your home — it has to be disclosed, corrected, or both, often at significant cost.

Every job we do is code-compliant and permitted where required. If you're not sure whether a job needs a permit, ask us — we'll give you a straight answer.

What warranty do you offer on repairs and installations?

All parts and labor come with a warranty — and we'll give you the specific terms in writing before any work begins, because "it's guaranteed" means nothing without a document.

For new equipment installations, we pass through the manufacturer's warranty and back it with our own labor warranty on top. For repairs, warranty length varies by part and type of work, and we'll be specific when we quote you.

We've been around since 1955. We're not going anywhere, which means our warranty is actually worth something.
