Installing a New Heating System in Tempe: Same Size, Same Place, No Permit
Tempe’s exemption spells out its limits. City Code Chapter 8, section 105.2, exempts replacing an air conditioner unit, furnace, heat pump or evaporative cooler in the same location with one of equal or less BTU, cfm and amperage rating, in a detached single-family home, two-family dwelling or townhome where the appliance serves one dwelling unit.
Step outside those limits and a permit applies. A larger furnace, a heat pump with a higher amperage rating than the equipment it replaces, or a unit moved to a new spot is no longer a like-for-like replacement. That can be the case when a home moves from a gas furnace to a heat pump, because the electrical ratings differ. We’ll tell you whether a permit applies.
Tempe’s code table gives a mean annual temperature of 71.2°F but leaves its Manual J design rows blank, so the city publishes no winter design temperature of its own; a footnote says they are to be filled in from the Phoenix Sky Harbor values in ACCA Manual J or criteria the city sets. The city moved to the 2024 International Codes on July 1, 2026. In a rental, Tempe’s Rental Housing Code requires permanently installed heating, under the tenant’s control, that can heat all habitable rooms and bathrooms to at least 70°F. When a permit does apply, applications go through the Tempe Citizen Access Portal, and the city says inspection requests received before midnight are inspected the following business day.

Signs You Need a New
HEATING SYSTEM IN Tempe
Uneven or Inadequate Heat
Rooms that never warm up, or a system that runs constantly during a cold snap, can mean the equipment is the wrong size for the house or is wearing out.
Rising Energy Costs
Heating costs that climb while your usage stays the same are a sign the system is losing efficiency.
Safety Warning Signs
A yellow flame on a gas furnace (it should be blue) needs checking, and a cracked heat exchanger is a safety concern and a reason to look at replacement.
Frequent Repairs
When repair costs keep climbing, replacement can make more financial sense. If your system is older or repairs are adding up, we look at how it’s running and its repair history, then explain your options.

Frequently Asked Questions — Heating Installation Tempe
How much does a new furnace or heat pump cost in Tempe?
It depends on the system type, your home’s size, the efficiency rating, and whether ductwork, gas or electrical changes are needed. We give you a written, all-in price before any work begins. Call (623) 240-9892 for a free estimate, or price your new system with our online tool.
Do I need a permit to replace a furnace or heat pump in Tempe?
Often not. Tempe’s code exempts a furnace or heat pump that goes in the same place as the old one with BTU, cfm and amperage ratings no higher, in a house, duplex or townhome. The same section adds that an exemption does not authorize work that violates the city’s codes. We’ll tell you whether a permit applies.
Which building codes apply to a heating replacement in Tempe right now?
It depends on when you apply. Tempe adopted the 2024 International Codes and the 2023 National Electrical Code effective July 1, 2026. Through December 31, 2026, permit applications may use either the 2018 or the 2024 codes; from January 1, 2027, all must meet the 2024 codes.
Can I replace electric strip heat with a heat pump in Tempe without a permit?
It depends on the new unit’s location and ratings. Tempe’s exemption covers the same location and equal or less BTU, cfm and amperage rating, along with minor changes to the electrical, plumbing and mechanical connections needed to serve the new appliance. A heat pump can differ from the equipment it replaces. We’ll tell you whether a permit applies.
What warranty comes with a new system?
Most new systems carry a 10-year manufacturer parts warranty once registered, and we register it for you. Terms vary by brand and model, and we’ll show you yours before you buy. Our work carries 1-year labor unless your proposal states otherwise, and financing is available.
