Installing a New Heating System in Mesa: Design Temperature, Ratings and Permits
Mesa’s building code sets a mild winter design day. Its climatic design table lists a winter design temperature of 32°F and a mean annual temperature of 71.2°F. Mesa adopted the 2024 International Codes and the 2023 National Electrical Code, in effect since January 8, 2026, and the city says they apply to permit applications submitted on or after that date.
Mesa’s code starts from the rule that replacing a gas, mechanical or electrical system needs a permit, then lists the work that is exempt, one permit type at a time. For a gas furnace replaced with one of equal or less Btu in an individual dwelling unit, no fuel gas permit is required, provided the gas utility is notified before the furnace is energized. The list also names replacing an electric furnace or heat pump with one of equal or less amperage. Both items include the minor changes to connections needed to serve the new appliance, and neither covers a larger unit. Which permits a particular swap still needs is the city’s call. We’ll tell you whether a permit applies.
Changing fuel raises more questions than a like-for-like swap. Going from a gas furnace to a heat pump, or adding a dual-fuel system, can change the electrical connections beyond the minor modifications the code allows, so ask before assuming an exemption applies. The city’s residential construction page lists installing or modifying electrical, plumbing or mechanical systems among the work that needs a construction permit, and applications go through its DIMES system.

Signs You Need a New
HEATING SYSTEM IN Mesa
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 Mesa
How much does a new furnace or heat pump cost in Mesa?
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 Mesa?
It depends on the swap. Mesa City Code says no fuel gas permit is required to replace a gas furnace with one of equal or less Btu in a single home, if the gas utility is notified before it is energized. Its exempt-work list also names like-for-like electric furnaces and heat pumps. We’ll tell you whether a permit applies.
My Mesa home is on City of Mesa gas. What changes when a new furnace goes in?
Two things to know. Mesa’s fuel gas permit exemption for a like-for-like gas furnace depends on the gas utility being notified before the furnace is energized, and the city’s gas utility says the piping from the meter to every gas appliance belongs to the property owner. We’ll tell you whether a permit applies.
Can I switch from a gas furnace to a heat pump in Mesa?
Yes. A heat pump heats and cools with one system and needs no gas line. Switching fuel may not count as a like-for-like replacement under Mesa’s exemptions. 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.
