What a full HVAC replacement includes
A full replacement typically means swapping the outdoor condenser, the indoor evaporator coil, and often the air handler or furnace together as a matched system, rather than replacing just one component. Matching all the parts matters more in Peoria than in milder climates, since a mismatched system loses efficiency fastest under sustained 110-plus-degree heat.
Most Peoria homes run a straight electric cooling system paired with either a gas furnace or an electric heat strip for the mild winters, and increasingly homeowners are considering heat pumps, which can handle both heating and cooling with strong summer cooling performance.
What drives replacement costs up or down
System size (measured in tons) is the biggest driver: a typical 1,800 to 2,200 square foot Peoria home usually needs a 3 to 4 ton system, while larger homes or ones with poor insulation may need more capacity, which raises equipment cost. Efficiency rating matters too, since higher-SEER2 equipment costs more upfront but runs less throughout the long cooling season.
Ductwork condition is often the wildcard. Homes with original, undersized, or leaky attic ductwork may need duct repair or replacement as part of the job, which can add several thousand dollars but meaningfully improves comfort and efficiency in a climate where duct leaks into a 140-degree attic waste real money every month.
Typical replacement cost ranges in Peoria
A condenser-and-coil-only replacement, keeping an existing compatible air handler or furnace, generally runs $4,200 to $7,000. A full system replacement including a new air handler or furnace typically runs $8,000 to $15,500 depending on tonnage, efficiency tier, and ductwork condition.
Heat pump systems, which handle both heating and cooling, tend to run somewhat higher upfront than a straight AC-plus-furnace setup but can simplify equipment to a single system. Mini-split installations for room additions or garage conversions typically run $3,800 to $7,000 for a single zone.
Permits and inspections for a replacement
A full system replacement in Peoria requires a mechanical permit through the City's Development and Engineering Department, and any gas furnace work needs a separate gas permit. Your contractor should handle the permit application and schedule the required inspection once installation is complete.
Ask your contractor to confirm the permit fee is included in your quote rather than added later, and ask when the inspection will be scheduled so the job is fully closed out, which matters for warranty coverage and for any future home sale.
Financing and rebates
Most Peoria HVAC contractors offer financing plans for full replacements, and it's worth comparing at least two financing offers alongside the cash price, since promotional rates and terms vary significantly between companies.
Depending on whether your home is served by SRP or APS, rebates for qualifying high-efficiency equipment may be available, though amounts and eligibility change from year to year. Confirm current program details directly with your utility and get any rebate estimate from your contractor in writing before including it in your budget.

Common questions
How much does a full HVAC replacement cost in Peoria?
Most full replacements, including a new furnace or air handler and condenser, run $8,000 to $15,500 depending on system size, efficiency, and ductwork condition.
What size system does my Peoria home need?
A typical 1,800 to 2,200 square foot home usually needs a 3 to 4 ton system, but a contractor should run a proper load calculation rather than sizing based on square footage alone, since insulation and window exposure matter a lot in desert heat.
Is a heat pump a good choice in Peoria?
Heat pumps can work well given Peoria's mild winters and long cooling season, though they typically cost somewhat more upfront than a straight gas furnace and AC combination.
Do I need a permit for a full system replacement?
Yes, a mechanical permit through the City of Peoria is required for most full system replacements, and gas furnace work needs a separate gas permit.
How long does installation take?
Most straightforward replacements are completed in a single day, though jobs that include significant ductwork repair or a system upsizing may take two days.
Are there rebates for a new high-efficiency system?
Possibly, depending on whether your home is served by SRP or APS, since Peoria is a split-utility city. Check current program terms directly with your utility before counting on a specific rebate amount.
