AC Installation in Overland Park, KS
A new air conditioner in Overland Park has to carry a humid Johnson County summer for the next 12 to 15 years, and in a city this varied, sizing it right means knowing which Overland Park you’re in. 7th Degree Heating and Air installs cooling systems across OP that are sized with a load calculation rather than a tonnage guess — and from our base just east in Leawood, we know the difference between a 1970s home near Shawnee Mission and a new Blue Valley build.
North OP and South OP Size Differently
This is where local knowledge matters. An older home in northern Overland Park — original windows, modest attic insulation — carries a higher cooling load per square foot than a newer build south along 135th, 151st, and 159th or in Blue Valley, framed to the modern IECC envelope (R-20 walls, R-49 ceiling, U-0.32 windows). Size both by the same rule of thumb and you’ll oversize the new build, which then short-cycles and leaves it cool but damp, while possibly undersizing the older one. We run an ACCA Manual J load calculation, pick equipment with Manual S, and verify ducts with Manual D, sizing for the latent humidity load that defines comfort in Climate Zone 4A.

Frequently Asked Questions
- How do you size an AC for my Overland Park home?
- With a Manual J load calculation, not the old unit’s size or a square-footage rule. In Overland Park that matters because an older north-OP home and a newer Blue Valley build carry very different loads. Right-sizing lets the system run long enough to pull humidity out instead of short-cycling.
- I have a newer Blue Valley home — why does sizing matter so much?
- Because tight, well-insulated newer homes carry a lower cooling load than their size implies. Size by square footage and you oversize the AC, which short-cycles, never running long enough to dehumidify, so the house feels cool and clammy. A Manual J calculation prevents that.
- What refrigerant will my new Overland Park AC use?
- R-454B, the lower-global-warming-potential refrigerant that replaced R-410A in new residential equipment as of the 2025 transition. Installing to the current standard keeps your equipment and parts supply supported for years.
- How long does an AC installation take?
- A straightforward replacement is usually a single day. Line set changes, electrical work, or ductwork modifications can extend it. We give you a realistic timeline with the quote.
- Do you remove my old unit?
- Yes. We recover the old refrigerant per EPA Section 608, haul away the equipment, and handle disposal as part of the installation, not as an add-on.
