Quick answer: Chandler's long cooling season and mild winters suit heat pumps. Size the system for the cooling load, size backup heat for the coldest nights, and choose two-stage or variable-speed equipment for two-story homes.
Chandler’s climate suits heat pumps well: long, hot summers where the cooling side earns its keep, and short, mild winters where heating demand is light. Whether you are replacing an old heat pump or switching from an AC-plus-gas-furnace setup, here is what to think through.
Sizing for both seasons
In Chandler the cooling load sets the size. A proper load calculation uses local design temperatures, your home’s orientation, windows and insulation, and where the ducts run. Backup heat strips are then sized for the coldest nights; the city’s record low is 15°F.
Equipment choices
| Type | Best for |
|---|---|
| Single-stage split heat pump | Budget replacements, single-story homes |
| Two-stage | Two-story homes; longer, quieter low-stage runs |
| Variable-speed (inverter) | Most even temperatures, best humidity control during monsoon |
| Package heat pump (rooftop) | Flat-roof homes with no attic air handler |
| Ductless mini-split | Additions, casitas, converted garages |
Switching from a gas furnace
Many Chandler homes pair an AC with a gas furnace. Moving to a heat pump removes the furnace’s combustion safety concerns and the annual heat exchanger inspection, but may require an electrical panel review and an air handler with heat strips. A dual-fuel setup (heat pump plus gas furnace backup) is another option if your furnace is young.
Permits and inspection
Chandler’s Development Services department handles building permits from 215 E. Buffalo St. The city’s Homeowner’s Building Permit Manual (revised April 2026) exempts like-for-like swaps of water heaters, furnaces and evaporative coolers, but it does not list air conditioners or heat pumps as exempt. If you are unsure whether your job needs a permit, the city’s Plan Reviewer of the Day takes questions at 480-782-3078. We pull the permit when one is required, and we tell you before work starts.
Utility rules
Chandler is served by both SRP and APS, and each sets its own rebate requirements for new heating and cooling equipment. We check the current program for your utility when we quote; rebate rules change during the year.
What to get in writing
- Model numbers for the outdoor unit, air handler and heat strips.
- Load calculation results.
- Permit, crane (if any), and disposal of old equipment.
- Warranty terms and registration responsibility.
Common questions
Can a heat pump replace my gas furnace in Chandler?
Yes. January lows average 41°F, so a heat pump with backup heat strips handles most winters. A dual-fuel setup keeps a young furnace as backup.
Do I need a permit for a heat pump?
The city's permit manual does not list heat pump replacement as exempt, so expect a permit.
