For 2026, our planning ranges in the Edmond and Oklahoma City area are $3,000 to $9,800 for an air conditioner replacement, $2,500 to $8,000 for a furnace installation, and $5,200 to $15,000 for a matched AC and furnace system. These are budget estimates, not quotes. Your actual price depends on what we find at your home, and we put it in writing before any work starts.
2026 planning ranges for a new system
Most homes in the metro use a split system: an outdoor air conditioner or heat pump paired with an indoor furnace or air handler. When both halves are near the end of their service life, replacing them together is usually the most practical choice, because the indoor and outdoor equipment are designed to work as a matched set.
| Project | Planning range |
|---|---|
| Air conditioner replacement | $3,000 to $9,800 |
| Furnace installation | $2,500 to $8,000 |
| AC and furnace together | $5,200 to $15,000 |
If you only need an air conditioner, our guide to AC installation cost in Oklahoma City covers that project in more detail. This article focuses on replacing the whole system. For a quick number based on your own home, try our budget calculator, then use the in-home estimate to confirm it.
Why the ranges are wide
Two houses on the same street can land at opposite ends of these ranges. The equipment price is only one part of the total. Labor, ductwork, electrical and gas connections, code items, refrigerant lines, and the physical difficulty of the job all add up, and they vary far more from house to house than the equipment does.
Many Edmond homes were built between the 1970s and the early 2000s. Older homes near downtown Edmond or along Boulevard often need duct repairs or modifications before a new system can perform well. Newer homes in areas such as Coffee Creek or Spring Creek more often have ductwork that is still in reasonable shape. What is already behind your walls and in your attic shapes the final number as much as the equipment you pick.
System type sets the starting point
The type of system you choose has a larger effect on price than the brand name on the box.
Central air conditioner with a gas furnace
This is the most common setup in the metro and is usually the lowest-cost whole-system replacement when the existing ductwork is sized for it. It handles our hot summers and our cold winter nights, and the swap is fairly direct when the ducts, gas line, and electrical service are in good order.
Heat pump systems
A heat pump heats and cools with one outdoor unit. It is very efficient in mild weather, and the U.S. Department of Energy notes that heat pumps can cut the electricity used for heating by roughly half compared with electric resistance heat. During Oklahoma's sub-freezing stretches, a heat pump usually relies on backup heat. A heat pump system typically costs more upfront than a basic AC and furnace combination. A dual-fuel system, which pairs a heat pump with a gas furnace for the coldest days, costs more again because you are buying two types of heating equipment. Our heat pump services page explains how we match these systems to local homes.
Ductless mini-splits
Some older homes have little or no ductwork. In those cases, ductless mini-splits can be the most practical option. One or two zones are usually reasonable. A whole-home system with four or five indoor units costs considerably more, because the equipment multiplies with each room you add. Heat pump and mini-split projects are quoted after an assessment, since they depend heavily on the layout of the home.
What moves a quote within the range
Once the system type is settled, these factors decide where your project lands.
- Size and capacity. A 1,200-square-foot ranch needs a very different system than a 2,800-square-foot two-story. Larger homes need more capacity, larger refrigerant line sets, and more labor.
- Ductwork condition. Leaky, crushed, or undersized ducts need sealing, repair, or replacement for the new system to deliver its rated performance. Skipping that work leaves a new system fighting the same problems as the old one.
- Efficiency rating. Higher SEER2 air conditioners and higher-efficiency furnaces cost more upfront and use less energy each month. The value of that upgrade depends on how long you plan to stay in the home and how hard your system runs.
- Electrical and code items. Older homes may need a new disconnect, updated wiring, a new circuit, gas line changes, or condensate drain corrections to meet current code. If your system has not been replaced in 15 or 20 years, expect a few of these.
- Access and location. Equipment in a tight attic or a cramped closet takes longer to remove and install than equipment in an open garage or basement.
- Thermostat and air quality add-ons. New thermostats, filtration upgrades, or zoning are optional, but they change the total.
Sizing comes before pricing
A system that is too large for your home short-cycles. It turns on and off often, wears parts faster, and can leave the house feeling clammy because it does not run long enough to remove humidity. A system that is too small runs constantly and still falls behind on the hottest afternoons.
The right size comes from a load calculation, commonly called a Manual J, which accounts for insulation, windows, sun exposure, air leakage, and layout. A common mistake we see is choosing a system based on a neighbor's recommendation without having your own home evaluated. Your neighbor's house may face a different direction or have large west-facing windows, while yours may be shaded by mature trees. Those details change the result. Our HVAC sizing guide for Oklahoma explains the process in more detail.
How we price a replacement
We offer free estimates on replacement systems. A technician looks at your current equipment, checks the ductwork and electrical, talks with you about comfort problems in the house, and recommends options that fit. We do not use commissioned sales reps, so the recommendation is based on what your home needs rather than a sales target.
We use flat-rate pricing. The price is quoted and approved before work starts, so there are no added charges partway through installation day. Manufacturer equipment warranties are separate from our workmanship and depend on registration and the manufacturer's terms, so we walk you through what applies to your equipment.
If your current system is not working and you are not sure whether it should be repaired or replaced, a repair visit starts with an $89 diagnostic, which is waived when you go ahead with the repair. That visit gives you a clear picture of the failure before you decide whether a new system makes sense.
Planning your budget for 2026
A few steps make the process easier:
- Note the age of your current equipment and any recurring repairs or comfort problems.
- Use the planning ranges and the budget calculator to set a realistic expectation.
- Decide whether you are open to a heat pump or dual-fuel system, or prefer a standard AC and furnace.
- Get an in-home estimate that includes a load calculation and a look at the ductwork.
- Compare written quotes line by line, checking equipment, ductwork, electrical, and code items.
On incentives, the federal 25C energy efficiency tax credit does not apply to equipment placed in service after December 31, 2025. Utility and manufacturer rebates change from season to season, so check the current programs on our rebates page before you count on them. If you would like to spread the cost out, ask us about current payment options.
