Ten months of cooling asks a lot of a new system
Lakeland asks a new air conditioner to run from February through November, ten months a year, with summer afternoons averaging 92°F. The compressor is working almost the whole year here, not just a few summer months.
A system installed here needs to hold up to that stretch of duty, and it needs to be sized right to keep up on the hottest afternoons without running nonstop. Any new central air conditioner built since 2023 has to meet a federal minimum of 14.3 SEER2, so that efficiency level is the baseline to expect, not an upgrade.

Florida requires HVAC contractors to hold a state license.
The state license is tied to the contractor, not to your specific job. Florida's Construction Industry Licensing Board tests and records the person or company before they can hold that license, so anyone installing your air conditioner in Polk County should be able to show a state license number, not just a business name.
Because this is an installation, Polk County's building office will also need to be involved. Most cities and counties require a permit before a new air conditioner goes in, and an inspection once it is done, separate from anything the state license covers. That inspection is what checks the installation itself, not the contractor's license.

- What size air conditioner does my house need?
- There's no single answer without a load calculation done for your specific house. A contractor figures this out by looking at your square footage, insulation, window placement and orientation, and how many people live there, not just square footage alone. Going bigger than what you need isn't a safety net either. An oversized unit cools the air fast but shuts off before it pulls the humidity down, so the house feels clammy even at the right temperature. With cooling needed here from February through November, getting the size right matters more than it would somewhere with a short summer.
- Should I replace the whole system or just the outdoor unit?
- In most cases, replace both together. The outdoor condenser and the indoor coil are matched to work at a specific efficiency, and pairing a new condenser with an old coil usually means you don't get the efficiency rating you paid for, and it can shorten the life of the new unit. If your indoor coil is old enough that the outdoor unit is failing around the same time, there's a good chance the coil isn't far behind it. A contractor can check the age and condition of the coil before telling you whether it's worth keeping.
- Do HVAC contractors in Lakeland need a state license to work on my home?
- Yes. Florida requires HVAC contractors to hold a state license, issued by the Construction Industry Licensing Board. Before hiring anyone, you can confirm their license is active and in good standing directly with the board.
