AC Installation & Replacement
AC Installation and Replacement in Kansas City and Lenexa, KS
A new air conditioner is one of the larger investments a homeowner makes, and the decision deserves more than a quick upsell. Lutz has been installing cooling systems in Kansas City and Johnson County for over a century. Our approach starts with an honest assessment of your current system and a proper load calculation for your home — because the right size and the right equipment make a bigger difference in comfort and efficiency than the brand name on the box.
We install and service all major residential cooling brands. All installations comply with current Kansas and Missouri SEER2 minimum efficiency requirements. Financing is available for qualifying customers.

How to Know When Replacement Is the Right Decision
Most homeowners reach the replacement decision through one of a few paths: the system fails and the repair cost makes replacement the smarter investment, the unit is old enough that its remaining useful life does not justify continued repair costs, or the system is simply no longer keeping up with summer demand in a way that seasonal repairs cannot fix.
Some specific signals that replacement is worth serious consideration:
- The system uses R-22 refrigerant, which is no longer manufactured and costly to source for repairs.
- The compressor has failed — often the costliest single component in a system, and rarely worth replacing in a unit over 12 years old.
- You have repaired the system two or more times in a single season.
- The unit is over 15 years old and the last summer required it to run continuously without achieving the set temperature.
- Energy bills have climbed steadily even though usage patterns have not changed.
When repair is still the right call, we will tell you that too. See our AC repair page for the framework we use when making repair-versus-replace recommendations.
The Right Size Matters More Than Most Homeowners Realize
Oversized air conditioners are one of the most common installation problems in the Kansas City market. A unit that is too large for the space it serves will cool the air quickly but shut off before it has run long enough to remove humidity. In a climate like Johnson County’s — where summer humidity regularly climbs above 70% — that means a house that is technically at the thermostat temperature but feels clammy and uncomfortable.
Before any installation, we perform a Manual J load calculation that accounts for your home’s square footage, insulation levels, window area and orientation, ceiling height, duct condition, and local climate data for the Lenexa area. This calculation determines the correct tonnage and airflow for your specific home, not a rough estimate based on square footage alone.
What Happens on Installation Day
A standard AC installation typically takes one day for most residential systems. Here is what to expect:
- The existing outdoor condenser unit and indoor evaporator coil are disconnected and removed. Refrigerant is recovered per EPA regulations before any components are removed.
- The new system is installed, including the outdoor condenser, indoor coil, lineset connections, and electrical connections. If the existing air handler or furnace is being retained, we verify compatibility and condition before connecting to it.
- We perform a startup and commissioning procedure: checking refrigerant charge, verifying electrical connections and startup current draw, testing thermostat operation, and measuring supply air temperatures at registers throughout the home.
- Before leaving, we walk you through the new system controls, filter location and replacement schedule, and what normal operation looks and sounds like.
Efficiency, SEER2, and What It Means for Your Utility Bills
Since January 2023, new central air conditioners installed in Kansas must meet a minimum efficiency rating of 14.3 SEER2. Most systems we install exceed this. For homeowners who run their systems heavily through a Kansas City summer, upgrading from an older 10-12 SEER unit to a modern 16-18 SEER2 system typically reduces cooling energy consumption by 25-35%.
KCP&L (Evergy) and Kansas Gas Service occasionally offer rebates for high-efficiency equipment installations. We will advise you on any currently available programs at the time of your installation consultation.
Lutz Loyalty Club: Protecting Your New Investment
A new air conditioner is a significant investment. Joining the Lutz Loyalty Club ensures that investment is protected with annual maintenance visits, priority scheduling, and member pricing on any future service calls. Most manufacturer warranties also require documentation of annual professional maintenance — our maintenance records satisfy those requirements.
Frequently Asked Questions
How much does a new air conditioner cost in the Kansas City area?
The cost of a new central AC system in the Kansas City metro typically ranges from $3,500 to $8,000 or more installed, depending on system size (tonnage), efficiency rating (SEER2), brand, and the complexity of the installation. Single-zone systems on the lower end of the size range are less expensive; larger homes or high-efficiency multi-stage systems run higher. We provide a specific written quote after the load calculation and home assessment — no vague ranges or surprise charges.
How long does AC installation take?
A standard residential replacement installation typically takes four to six hours for the outdoor and indoor components. Installations that also involve replacing the air handler or adding a new thermostat may take a full day. We will give you a specific time estimate during the scheduling process.
What AC brands does Lutz install?
We install and service all major residential brands including Carrier, Trane, Lennox, Rheem, Ruud, Goodman, American Standard, and others. Brand selection is often less important than proper sizing and installation quality. We will discuss options that fit your home and budget during the consultation.
What is a Manual J load calculation and why does it matter?
A Manual J load calculation is an engineering calculation that determines exactly how much cooling capacity your home requires, based on insulation, windows, square footage, ceiling height, and local climate data. Without it, system sizing is guesswork. An oversized system short-cycles and leaves your home humid; an undersized system runs constantly and cannot reach set temperature on the hottest days. We perform this calculation on every new installation.
Does Lutz offer financing for a new AC system?
Yes. Financing is available for qualifying customers. See our financing page for current options, or ask during your installation consultation.
What is the minimum SEER2 for a new AC in Kansas?
As of January 1, 2023, the minimum efficiency standard for new split-system central air conditioners installed in Kansas (South region, which includes Johnson County) is 14.3 SEER2. We recommend considering higher-efficiency options if you use your cooling system heavily — the utility savings over the life of the equipment can offset the higher upfront cost.
My home was built in the 1970s. Are there any issues I should know about before replacing my AC?
Older homes in the Prairie Village, Merriam, Leawood, and Mission areas often have ductwork that has not been inspected or cleaned in many years. Before installing new equipment, we assess duct condition, seal any significant leaks, and verify that airflow is adequate. A high-efficiency system installed on a leaky or undersized duct system will not perform as expected. We will flag any duct issues during the pre-installation assessment.
Can I replace just the outdoor condenser unit without replacing the indoor coil?
In some cases, yes — but it depends on system age, refrigerant type, and coil compatibility. Mixing a new high-efficiency outdoor unit with an older indoor coil of a different efficiency class can void the manufacturer warranty and reduce the system’s rated efficiency. If your indoor coil is more than ten years old, replacing both components at the same time is usually the better long-term decision. We will give you a direct recommendation based on your specific system.
