Repair and maintenance costs
Routine maintenance runs $100-$200 per system per year, and it's the cheapest way to avoid larger repair bills during Kansas City's demanding summer and winter seasons.
Common repairs range from $150 for a basic part swap to $1,500+ for major component failures like a blower motor or compressor.
Replacement costs
A new central AC system (around 3 tons, using the newer R-454B refrigerant) typically runs $4,800-$8,200 installed. A new gas furnace runs $3,800-$7,500 depending on AFUE rating and ductwork condition.
Replacing both furnace and AC together often runs $8,000-$14,500, and bundling the work can sometimes reduce total labor cost versus doing each separately.
What affects your quote
Home size, existing ductwork condition, and equipment efficiency rating all move the price. Older Kansas City homes with undersized or leaky ducts often need duct work included in the replacement quote, which adds $400-$2,200.
The 2026 refrigerant transition from R-410A to R-454B is also affecting pricing, since new equipment and some service tools built for R-454B can carry a premium as the industry ramps up supply.
Permits and licensing affect your total cost too
Replacement jobs inside Kansas City city limits generally require a mechanical permit through the City Planning and Development Department, and that permit fee is typically built into your contractor's quote. Confirm it's included before signing.

Common questions
What's the average cost of a new HVAC system in Kansas City?
A full furnace and AC replacement typically runs $8,000-$14,500 depending on home size, ductwork condition, and equipment efficiency.
Are permit fees included in HVAC replacement quotes?
Most Kansas City contractors build the mechanical permit fee into their quote, but it's worth confirming directly since permit requirements and fees vary by municipality across the metro.
Why are 2026 AC prices higher than a few years ago?
The industry-wide shift from R-410A to the lower-GWP R-454B refrigerant means new equipment designs, and pricing reflects that transition as supply ramps up.
Does a bigger house always mean a bigger HVAC bill?
Generally yes, since tonnage and ductwork needs scale with square footage, but older homes with inefficient ductwork can also drive costs up regardless of size.
How do I get an accurate HVAC quote for my Kansas City home?
The most accurate quotes come from a contractor doing an in-person load calculation and ductwork inspection rather than a phone estimate. Getting a few local quotes lets you compare apples to apples.
