How Much to Replace Both Your AC and Furnace at Once
How Much Does AC and Furnace Installation Cost in 2026?
AC and furnace installation cost in 2026 typically falls within these ranges:
| System Type | Typical Installed Cost |
|---|---|
| AC replacement only (existing ducts) | $3,500 – $9,000 |
| Furnace replacement only | $3,800 – $12,000 |
| AC + furnace bundled replacement | $7,000 – $18,000 |
| Heat pump (replaces both) | $6,000 – $25,000 |
| Ductless mini-split (per zone) | $2,000 – $4,000 |
Most Salt Lake area homeowners pay $8,200 – $12,400 for a complete heating and cooling setup. Replacing both units together saves $500 – $2,500 compared to doing each job separately.
When your furnace quits on a January night in Salt Lake City — or your AC gives out heading into a July heat wave — the last thing you want is sticker shock on top of the stress. A combined replacement is one of the bigger home expenses you'll face, and the price range is wide enough to be confusing.
The good news: understanding what drives that number puts you in control. The right system, sized correctly and installed by a trusted local team, can cut your energy bills for the next 15–20 years.
At All Pro Service Group, our team has been helping Greater Salt Lake homeowners navigate AC and furnace installation costs since 2008. We've completed thousands of heating and cooling installs across the valley, so we know exactly what honest pricing looks like in this market — and what red flags to watch for.

Average AC and Furnace Installation Cost in 2026
When we talk about the ac and furnace installation cost in 2026, we are looking at a national average that spans from $7,000 to $18,000 for a bundled system. However, for a standard-efficiency combo in a typical home, many families find the "sweet spot" is between $10,388 and $13,802. If you decide to go for high-efficiency, premium equipment, those costs can reach $17,304 or more.
It helps to see how the numbers break down when you compare doing the jobs one at a time versus doing them all at once. According to the True 2026 HVAC System Installation Cost & Pricing Guide, equipment prices have risen due to new regulatory standards, but bundling remains the most effective way to lower the total bill.
| Project Scope | Estimated Cost Range (2026) |
|---|---|
| New Furnace Only | $3,800 – $12,000 |
| New Central AC Only | $3,900 – $15,000 |
| Bundled (Furnace + AC) | $7,000 – $18,000 |
| Full System + New Ductwork | $12,000 – $28,000 |
Bundled Savings and Labor Efficiency
Why is it cheaper to do both at once? It’s all about efficiency—not just the system's efficiency, but our labor efficiency. When we come to your home for a bundled install, we only have to "mobilize" once. This means one set of permits, one trip for the heavy equipment, and one day (or two) of labor where our crew is already in the attic or basement.
By replacing the furnace and AC together, you can save anywhere from $500 to $2,500 in labor and administrative costs. Furthermore, because the furnace and AC share the same indoor blower motor, installing them together ensures they are perfectly matched.

Regional Price Variations in Utah
In the Greater Salt Lake area, our climate dictates specific needs. Whether you are in the high-altitude chill of Park City or the valley heat of West Jordan and Salt Lake City, your system needs to be robust. Labor rates in Utah are generally competitive, but the complexity of our homes—ranging from historic builds in South Salt Lake to modern estates in Provo—can influence the final quote. We often find that homeowners in Ogden or West Valley City may have different ductwork requirements than those in newer South Jordan developments, which can slightly shift the ac and furnace installation cost.
Key Factors Influencing Your Combined HVAC Quote
No two homes are exactly alike, which is why we never give a "one-size-fits-all" price over the phone. A professional quote requires a "Manual J" load calculation. This isn't just a fancy term; it's a technical assessment that looks at your home's square footage, insulation levels, and even which way your windows face.

Home Size and AC and Furnace Installation Cost
Size matters, but not in the way most people think. You don't just want the "biggest" unit; you want the right unit. A system that is too large will "short-cycle," turning on and off constantly, which wears out the parts and leaves your home humid.
For a typical 1,500–2,500 sq ft home in Utah, you’ll likely need a 2.5 to 4-ton AC unit and a furnace ranging from 60,000 to 100,000 BTUs. Larger homes or those with vaulted ceilings will naturally require higher capacity equipment, increasing the equipment portion of your Central Air Installation Cost (2026): Full Price Breakdown. If you're unsure who to trust for this assessment, see our Guide to choosing the right furnace provider.
Efficiency Ratings: SEER2 and AFUE
In 2026, efficiency is the name of the game.
- SEER2 (Seasonal Energy Efficiency Ratio 2): This measures AC efficiency. Most modern systems start around 13.4 to 14.3 SEER2. High-efficiency models can go over 20.
- AFUE (Annual Fuel Utilization Efficiency): This measures furnace efficiency. A 95% AFUE furnace means 95 cents of every dollar spent on gas goes directly into heating your home.
While a high-efficiency system has a higher upfront ac and furnace installation cost, the long-term ROI is significant. You can save $200–$900 annually on utility bills, which often pays for the price difference within 5 to 10 years.

Ductwork Condition and Modifications
Your HVAC system is only as good as the "veins" carrying the air. If your ductwork is leaky, undersized, or over 30 years old, it might need help. Adding new ductwork can add $3,000 to $8,000 to a project. However, often we can perform smaller modifications, like plenum adjustments or professional sealing, to ensure your new system doesn't whistle or struggle for air.
Comparing System Types: Gas, Electric, and Heat Pumps
The technology inside these boxes changed significantly by 2025 and 2026. The industry has moved toward A2L refrigerants, which are more environmentally friendly but require new safety sensors and specialized handling. This has contributed to a roughly 15-20% increase in equipment costs compared to previous years.

Understanding System Types and AC and Furnace Installation Cost
- Gas Furnace + AC: The traditional choice for Utah. It provides that "toasty" heat we love in the winter and reliable cooling.
- Heat Pumps: These have exploded in popularity. A heat pump can both heat and cool your home. Modern "cold-climate" heat pumps work effectively even when Salt Lake temperatures drop below freezing.
- Hybrid (Dual-Fuel): This pairs a heat pump with a gas furnace. The heat pump handles the mild days, and the gas furnace kicks in for the "Polar Vortex" weeks.
Expect to pay $7,500 to $15,000 for a quality air-source heat pump. You can find more details in our Complete guide to AC installation.
The Rise of Ductless Mini-Split Alternatives
If your home doesn't have ducts (common in some older Salt Lake City neighborhoods) or if you have a "bonus room" that never gets cold enough, mini-splits are the answer. These cost about $2,000–$4,000 per zone. They are incredibly efficient and allow for "room-by-room" temperature control. Explore these further in our Heating and air conditioning replacement options.
Maximizing Savings with Rebates and Timing
The sticker price of an ac and furnace installation cost can be intimidating, but 2026 offers some of the best financial incentives in history.
- Inflation Reduction Act (IRA): You can claim a federal tax credit (25C) of up to $2,000 for a qualified heat pump or up to $600 for a high-efficiency central AC or gas furnace.
- Utility Rebates: Local Utah utility companies often offer "instant" rebates that we can apply directly to your invoice, sometimes saving you another $500 to $1,500.
- Manufacturer Rebates: Brands like Bryant or Carrier often run seasonal promotions during the "shoulder seasons."
To keep your new investment efficient, don't forget the importance of Maximizing efficiency with annual tune-ups.
Best Time of Year for Installation
Timing is everything. If you wait until your AC dies during a 100-degree July day, you'll be paying peak prices and waiting in a long line. The "shoulder seasons"—Spring (March-May) and Fall (September-November)—are the best times to buy. We are often less busy during these months and can offer 10-15% discounts to keep our crews working.
Financing and Long-Term Value
Most homeowners don't have $12,000 sitting under a mattress. We offer flexible financing options to turn a large capital expense into a manageable monthly payment. Additionally, a new HVAC system adds significant resale value to your home. Buyers in the Salt Lake market love seeing a "Gephardt Approved" sticker on a system with a 10-year warranty. If you're wondering if you can squeeze one more year out of your old unit, check the Signs it is time for a furnace replacement.
Frequently Asked Questions about HVAC Replacement
Should I replace both units if only one has failed?
If your AC is dead but your furnace is 15 years old, replace both. Why? Because modern high-efficiency AC units require a specific blower speed that your old furnace might not be able to provide. Using an old furnace with a new AC can actually drop your SEER2 rating by 10-15%, essentially wasting the money you spent on the "high-efficiency" upgrade. We recommend the "$5,000 Rule": Multiply the age of the unit by the repair cost. If the result is over $5,000, it's time to replace.
How long does a complete furnace and AC installation take?
A standard "swap-out" where we use your existing ductwork usually takes 8 to 10 hours. We aim to have you back in comfort by dinner time. If we need to replace ductwork or move the equipment to a different part of the house, it can take 2 to 3 days. We always handle the permits and schedule the city inspections for you.
How can I tell if my HVAC quote is fair?
A fair quote should be itemized. It should clearly show the equipment model numbers, the labor costs, permit fees, and warranty details. If a contractor gives you a price on a napkin without doing a Manual J calculation, walk away. Always get at least three quotes and compare the "value," not just the bottom line. A cheaper install that is done poorly will cost you thousands in repairs later.
