Five months of heat is a real load on a new system
From May through September your air conditioner is working, with summer afternoons averaging 86°F. That is five months of the compressor cycling on to hold the house at temperature, longer than a lot of places ask of a system.
Lincoln County has also seen its share of hail and wind, 18 hail events and 36 damaging wind events over the past ten years, with hail up to 2.5 inches. The outdoor unit sits exposed to that. Any new central air conditioner installed here has to meet the federal minimum of 13.4 SEER2, so the starting point is already a more efficient machine than what many homes are replacing.

- What size air conditioner does my house need?
- The right size depends on your square footage, ceiling height, insulation, window count, and how much shade your house gets, not just one number that works for every home. An undersized unit will run constantly through Troy's summer afternoons and still not keep up with 86°F heat. An oversized one cools the air fast but shuts off before it pulls the humidity out, so the house feels clammy. A contractor works this out with a load calculation on the actual house, not a guess based on square footage alone.
- Should I replace the whole system or just the outdoor unit?
- If the indoor and outdoor units were installed together and matched, replacing only the outdoor unit usually causes problems. The compressor and coil are designed to work as a pair, and pairing a new outdoor unit with an old indoor coil can hurt efficiency and shorten the life of the new equipment. It can also make it harder to get the performance a new system is rated for. A contractor can check the age and condition of both parts and tell you whether the coil is worth keeping.
- Do HVAC contractors in Troy need a state license to work on my home?
- Yes. HVAC work on your home needs to be done by a licensed contractor, and you can ask to see that license before any work starts. Licensing means the contractor has met the state's requirements for training and knowledge of the codes that apply to installing and repairing this equipment. If a storm has damaged your outdoor unit, hail and wind both show up in this area's weather history, so it is worth asking specifically whether the license covers the repair work you need, not just installation.
