Four months of real heat, and storms in between
Summer afternoons in Springfield average 87°F, and cooling season runs June through September. That is four months where your air conditioner needs to start every time you ask it to.
Greene County also sees its share of hail and wind. Over the last ten years the area has logged 140 hail events and 302 damaging wind events, with hail up to 3 inches recorded. An outdoor unit sits exposed to all of that, so the condenser coil and cabinet take the brunt of a bad storm. If you're installing a new system, anything built since 2023 has to meet a federal minimum of 13.4 SEER2, so that baseline is already covered.

- What size air conditioner does my house need?
- The right size comes from a load calculation, not a formula based on square footage alone. A contractor measures your walls, windows, insulation, and how much sun your house gets before they size the unit. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy even at the right temperature. Undersized, and it runs nonstop on the 87 degree afternoons Springfield gets all summer and still won't keep up.
- Should I replace the whole system or just the outdoor unit?
- In most cases both the outdoor unit and the indoor coil should be replaced together. The two are matched to work at a specific efficiency and capacity, and pairing a new outdoor unit with an old coil usually means you lose the efficiency you paid for. It can also void the manufacturer's warranty on the new equipment. A contractor can look at the age and condition of your indoor coil and tell you whether it's worth keeping.
- Do HVAC contractors in Springfield need a state license to work on my home?
- Yes, anyone installing or servicing central air conditioning in a home needs a state HVAC license. Ask to see the license number before work starts, and check that it's current. A licensed contractor also carries insurance, which matters if something goes wrong during the install.
