AC Replacement Cost Factors
Ready to replace the old AC in your Kansas City home? Here are factors to consider when setting your project budget.
Home Size
The bigger the house, the bigger the AC you’ll need to cool down more space. For a 2,127 square foot home in Kansas City, an appropriate AC size would be around 3.5 to 4.5 tons. Here are the average costs of AC replacement by house size:
| Home Size (Sq. Ft.) | Tonnage | AC Cost |
|---|---|---|
| 1,200 | 1.5–2 | $895–$1,870 |
| 1,500 | 2–3 | $1,870–$2,810 |
| 1,800 | 2.5–3 | $2,340–$4,750 |
| 2,000 | 3–4 | $2,810–$6,330 |
| 2,200 | 3.5–4.5 | $3,274–$7,120 |
| 2,500 | 4–5 | $3745–$7,915 |
| 3,000 | 5+ | $4,680–$11,000 |
AC Unit Size
The size of your home will help determine what AC size you need. For every 400 to 500 square feet, you’ll need about one ton of AC, or about 12,000 British thermal units (BTUs).
What is a BTU?
BTU, or British Thermal Unit, is a unit that measures how much energy it takes to raise the temperature of one pound of water by one degree Fahrenheit. For heat pumps, each ton of capacity is equivalent to roughly 12,000 BTUs.
Consult with an HVAC pro in Kansas City, Missouri, to find the correct AC size for your house.
| Tonnage | BTUs | Cost |
|---|---|---|
| 1.5 | 18,000 | $895–$1,870 |
| 2 | 24,000 | $1,870–$2,810 |
| 3 | 36,000 | $2,810–$6,330 |
| 4 | 48,000 | $3,274–$7,120 |
| 5 | 60,000 | $4,680–$11,000 |
Type of AC

In Kansas City, the most common type of AC is split-system central air, although many households also benefit from options like window units, ductless zones, and even energy-efficient geothermal heat pumps.
| Type of AC | Average Cost | Pros | Cons |
|---|---|---|---|
| Central | $3,274–$7,120 | Whole-house cooling | Requires ductwork |
| Window | $60–$400 | Low cost | Limited cooling capacity |
| Portable | $80–$700 | Moves from room to room | Takes up floor space |
| Ductless | $5,000–$28,000 | No need to install ducts | Multiple units or zones needed |
| Geothermal | $22,200–$59,200 | Energy-efficient | Difficult to install |
Efficiency (SEER)

The higher the Seasonal Energy Efficiency Ratio (SEER), the more the AC will cost up front. But a major benefit of high-efficiency AC is that it can reduce your ongoing costs, such as for repairs and utility bills. In Kansas City, all new AC systems must meet at least 14 SEER.
| SEER | Cost |
|---|---|
| Standard efficiency (14–15) | $895–$5,047 |
| High efficiency (16–18) | $3,274–$7,120 |
| Premium efficiency (19+) | $7,120–$11,000 |
HVAC Pro Costs
Installing a new AC system, even if you replace your existing system with the same type of AC, requires an HVAC pro who is certified to handle refrigerant. Make sure to consider these labor and permit costs before you start your project.
Labor
Labor costs about $500 to $2,500 of the total cost of AC replacement, and your AC installation pro will ensure your new system is installed properly and works as efficiently as possible.
Permits
AC replacement projects in Kansas City require an “Electrical, Plumbing and Mechanical Permit” from the City Planning & Development department. Your HVAC pro will handle the process of applying for permits and will build the cost into their project quote.
Fees are $58 for projects between $1,001 and $2,000, plus $4.33 for each additional $1,000 (or fractional part of $1,000). For example, an average $5,047 AC replacement would require a $70.99 permit. However, always check with your HVAC pro or the planning department for exact permit and inspection costs.
Additional Pros to Consider Hiring
With some AC replacement projects, you may need additional upgrades to your home’s electrical system and plumbing to support the new AC.
Electrician: AC requires a dedicated circuit to prevent overloading the system or leaving other appliances without power. A local electrician can safely upgrade your electrical panel. Hiring an electrician in Kansas City costs an average of $149 to $486.
Plumber: A local plumber can install a proper drain line for your new HVAC system if your HVAC pro isn’t able to. Hiring a plumber in Kansas City costs an average of $167 to $443.
Does AC Replacement Increase Home Value?
AC, especially energy-efficient systems, is an attractive feature to home buyers in Kansas City. Replacing an inefficient or old AC system can deliver a return on investment (ROI) of around 30% and can increase home value by about 5% to 7%. The more efficient the new system, the better the ROI.
