Heat Pump Trouble Won't Wait for Cooler Weather
In Phoenix, a failing heat pump means a house that can't handle the cooling season. Get it installed, replaced or repaired by a licensed pro.
01
An air source heat pump is one system that cools and heats, so installation, replacement and repair all fall under one service. In Phoenix, cooling does most of the work. The city recorded 113 consecutive days at or above 100 degrees in 2024, and equipment runs hard through all of it.
Watch for these repair signs:
Repeated repairs, aging equipment and rooms that never even out point toward replacement.
How serious is it

What to do Get a replacement quote
A repair call in Chandler or Gilbert in July is a bad time to learn the system was already on its way out.
Sound familiar? The system runs but the house won't cool. You reset the breaker and swapped the filter. It worked for a day. Now it's blowing warm air and the repair is bigger than it needed to be.
Waiting makes small faults grow into larger repairs. A stressed system rarely fails on a mild day.

A typical installation follows these steps, summarised here before the full list.
Step by step
Installation at a glance
Site visit
The contractor assesses the home, ducts and existing equipment.
Equipment selection
Type and size are matched to the load.
Permit check
Local rules for like-for-like work vary, so confirm which applies.
Removal
The old equipment comes out.
Units set
Indoor and outdoor units are placed.
Lines and connections
Refrigerant, electrical and condensate lines are connected.
Startup testing
The system is run and checked.
Walkthrough
The installer shows you the finished work.
Sizing must meet local code. Installers also need specialized tools such as manifold gauges, vacuum pumps and recovery machines, which is one reason DIY installs go wrong.
Many installs are done in a day, but weather and ductwork surprises can add time.
Spring and fall are easier on crews and homeowners than the middle of summer.
04
The Arizona Registrar of Contractors licenses HVAC contractors. Cities handle permits, not trade licenses.
Search the contractor in the ROC Contractor Search. Confirm the status is active and the class covers your contract. Then call the number on the record.
Checklist
Questions to ask before you hire

Tick them off as you go. Nothing is saved or sent.
A license does not guarantee insurance, and the ROC requires workers' compensation only.
Ask for proof of coverage directly.

A heat pump is a poor fit for some homes, especially those with very cold winters, very high heating loads, or unsuitable existing ductwork. In the Phoenix area, most homes do well with heat pumps because winters are mild, but a few situations still call for a different system.
