Five months of Warrensburg summer, and the hail that comes with it
Summer afternoons in Warrensburg average 87°F, and a new air conditioner has to hold that line from May through September. That is five months of steady run time each year, not just a few hot weeks.
Johnson County has also logged 73 hail events and 61 damaging wind events over the past ten years, with hail as large as 2.5 inches. The outdoor unit sits outside through all of that, so the condenser coil and its housing take the weight of these storms. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, insulation, window placement, and layout, not just a rule of thumb. A unit that's too big cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. One that's too small runs constantly and still can't keep up on the hottest afternoons here, when temperatures push past 87°F. A contractor will run a load calculation on the actual house to get this right.
- Should I replace the whole system or just the outdoor unit?
- If your indoor and outdoor units are the same age, replace both. An old indoor coil paired with a new outdoor unit rarely runs at the efficiency either piece was built for, and the mismatch can shorten the life of the new equipment. If the indoor coil and ductwork are still in good shape and only the outdoor unit failed, a contractor can tell you whether it's a safe match. This matters more here than in mild climates, since the system runs hard for five months straight, May through September.
- Do HVAC contractors in Warrensburg need a state license to work on my home?
- Missouri does not license HVAC contractors at the state level, so licensing rules for this work come from the city or county instead. Ask any contractor you're considering what license or permit applies to work in Warrensburg, and ask to see it. A contractor who pulls permits and handles inspections properly is a good sign they do the rest of the job the same way.
