Furnace & Heat Pump Installation in Phoenix, Arizona

Planning a furnace replacement or heat pump installation in Phoenix before the heating season leaves time to compare quotes and arrange any permit, rather than replacing a failed system in cold weather.

Installing HVAC in Phoenix: What Is Local

Last reviewed October 26, 2026 · How we research

Phoenix is in Maricopa County, climate zone 2B, a hot, dry climate where cooling is the main job of a home's HVAC system. The City adopted the 2024 International Energy Conservation Code, Mechanical Code and Residential Code, with local amendments under Ordinance G-7397, effective August 1, 2025. Electricity in Phoenix comes from one of two utilities depending on the address: SRP, which describes itself as the largest electricity provider in the greater Phoenix metropolitan area, or APS, whose service area maps cover the Phoenix metropolitan area. The City's Planning and Development Department lists air conditioner repairs or replacements that do not increase size and capacity or change location as work that does not need a permit, while projects that include gas line modifications do. A larger system or a new equipment location means checking with the department before work starts.

• Climate: Climate zone 2B (hot, dry); Phoenix enforces the 2024 IECC with local amendments since August 1, 2025
• Utilities: SRP or APS supplies electricity, depending on the address
• Air conditioner repairs or replacements that don't increase size and capacity or change location are listed by the City as work that does not need a permit
• Projects that include gas line modifications do need a permit
• Permits: Planning and Development Department (residential permits)

Heat Pump and Furnace Installation in Phoenix

In Phoenix, cooling is the bigger job, and a heat pump does both: it cools the way an air conditioner does and runs in reverse to heat. Under the U.S. Department of Energy standard, split-system heat pumps manufactured from January 1, 2023 must reach at least 14.3 SEER2 and 7.5 HSPF2. Unlike central air conditioners, heat pumps have no separate Southwest minimum, so the same figures hold nationwide. Non-weatherized gas furnaces must reach 80 percent AFUE, and units manufactured from December 18, 2028 must reach 95 percent. ACCA Manual S is the method for selecting and sizing heating and cooling equipment, and it works from the home's heating and cooling loads and the manufacturer's performance data. In a hot, dry climate it is worth asking each contractor which load set the size of the system in their quote. As of October 2026, the City of Phoenix lists projects that include gas line modifications as work that needs a permit, which matters when a gas furnace is removed or swapped for a heat pump.

• Split-system heat pumps manufactured from January 1, 2023: at least 14.3 SEER2 and 7.5 HSPF2, the same in every region
• Non-weatherized gas furnaces: at least 80 percent AFUE, rising to 95 percent for units manufactured from December 18, 2028
• City of Phoenix: projects that include gas line modifications need a permit

Air Conditioning Installation in Phoenix

Air conditioning installation in Phoenix follows the U.S. Department of Energy's Southwest regional standard, which covers Arizona, California, Nevada and New Mexico. Split-system central air conditioners installed in Arizona from January 1, 2023 must reach at least 14.3 SEER2 below 45,000 Btu/h, or 13.8 SEER2 at 45,000 Btu/h and above. The Southwest standard also sets an EER2 minimum: for split systems below 45,000 Btu/h it is 11.7 when the unit's SEER2 is below 15.2, and 9.8 when it is 15.2 or higher. Under the EPA's Technology Transitions rule, new residential air conditioning and heat pump systems are limited to refrigerants with a global warming potential of 700 or less from January 1, 2025, although a system whose components were all made or imported before that date can still be installed. Because the City does not require a permit for a same-size, same-location replacement, the equipment model numbers and their SEER2 and EER2 figures in each written quote are the way to see what is being installed. A heat pump cools the same way an air conditioner does and also heats.

• Southwest regional standard: split-system central air conditioners installed from January 1, 2023 need at least 14.3 SEER2 below 45,000 Btu/h
• EER2 minimum for split systems below 45,000 Btu/h: 11.7 with SEER2 under 15.2, or 9.8 at 15.2 SEER2 and above
• City of Phoenix: no permit for air conditioner replacements that don't increase size and capacity or change location

HVAC Installation Cost in Phoenix

HVAC installation costs in Phoenix depend on the system type and capacity, the condition of the ductwork, any venting or electrical changes, and the local permit fee, so the reliable figure is a written quote for your home.
