Five months of cooling, and hail to survive along the way
Raymore homes run the air conditioner May through September, five months a year, with summer afternoons averaging 87°F. That is the stretch your new system has to handle without a break, so it needs to be sized and installed to hold up through a full season of steady heat, not just get through a hot week.
Cass County has also logged 74 hail events and 89 damaging wind events over the past ten years, with hail up to 5 inches recorded. The outdoor unit sits outside through all of that, so how it is installed and protected matters as much as the equipment itself. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2, so that baseline is already built into what you're getting.

- What size air conditioner does my house need?
- There's no single number for this until someone works out the load for your house. Square footage matters, but so does how much shade your house gets, how many windows face west, how well insulated the attic is, and how airtight the place is. A unit that's too big cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy even at the right temperature. A contractor will run a load calculation on your actual house, not just measure the floor plan, and size the equipment from that.
- Should I replace the whole system or just the outdoor unit?
- In most cases it's better to replace both the outdoor condenser and the indoor coil together. They're matched to work at a specific efficiency and capacity, and pairing a new condenser with an old coil often means the system never runs the way it's rated to. Refrigerant type is part of this too. Older systems use R-22, which new condensers aren't built to run on, so the coil has to change along with it. A contractor can tell you what your existing coil is rated for and whether it can pair with new equipment.
- Do HVAC contractors in Raymore need a state license to work on my home?
- Ask any contractor for their license number before work starts and check that it's current. A licensed contractor also carries the insurance that protects you if something goes wrong during install, which matters with equipment that involves refrigerant lines and electrical work. If you're not sure what to ask for, a contractor can tell you what's required for the job at your address.
