What Madisonville summers ask of a new system
Your air conditioner in Madisonville works from May through September, five months of the year, with summer afternoons averaging 87°F. That is the stretch it has to run without a break, so the unit you put in needs to be sized and installed to hold up over that whole run, not just get through a hot week.
Hopkins County has also seen its share of rough weather, including 19 hail events and 68 damaging wind events over the past ten years, with hail up to 1.75 inches. The outdoor unit sits exposed to all of that, so how it's installed and protected matters. Any new central air conditioner going in now also has to meet the federal efficiency minimum of 14.3 SEER2, which is the baseline a licensed contractor will build your installation around.

Kentucky requires HVAC contractors to hold a state license.
The license comes from the Department of Housing, Buildings and Construction, and the state tested the contractor and keeps that record on file. It covers the contractor as a whole, not the individual job, so the license tells you this business met the state's standard, not that this particular installation was checked as it happened.
That check comes from the local building office. In most cities and counties in Kentucky, putting in a new air conditioner needs a permit before the work starts and an inspection once it is done. The license tells you who is allowed to do the job. The permit and inspection are what confirms this installation was done right.

- What size air conditioner does my house need?
- The right size depends on your home's square footage, layout, insulation, and how much shade and sun it gets, so there is no single number that fits every house. A contractor works this out with a load calculation, not a chart based on square footage alone. Going too big is as much a problem as going too small, since an oversized unit cools the air fast but shuts off before it pulls the humidity out, leaving rooms feeling damp. With summer afternoons here averaging 87°F for five months of the year, getting this calculation right matters for how the system holds up through the season.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit were installed together and matched for the same refrigerant and capacity, replacing only the outdoor unit can throw that match off and hurt both efficiency and cooling. A contractor can tell you whether your indoor coil will pair correctly with a new outdoor unit, or whether its age and condition mean it should be replaced too. Any new outdoor unit installed today also has to meet the federal minimum of 14.3 SEER2, which is worth asking about if your indoor coil is older. This is a case where a contractor needs to look at what you have before answering for your house specifically.
- Do HVAC contractors in Madisonville need a state license to work on my home?
- Yes. Kentucky requires HVAC contractors to hold a state license, issued through the Department of Housing, Buildings and Construction, and this covers installing your air conditioner. The license is held by the contractor, not issued separately for each job. On top of that, most cities and counties require a permit for replacing an air conditioner, along with an inspection once the work is finished, so ask whether that is being pulled for your job.
