Three months of real work, then a long rest
Your air conditioner in Woodbury earns its keep from June through August, with summer afternoons averaging 80°F. That is a short season compared to what other parts of the country ask of a unit, but it still needs to hold up and cool the house on the hot days in between.
Woodbury has also seen 77 hail events and 26 damaging wind events over the past ten years, with hail up to 2 inches recorded. Any outdoor unit here sits through that. If you're installing new, it will meet the federal minimum of 13.4 SEER2, the efficiency floor for central air conditioners built since 2023.

Minnesota has no state license for HVAC contractors.
Minnesota has no state license or registration for HVAC contractors doing home work, and that includes installing an air conditioner. There is no state list to check and nothing tested at the state level before someone can take this job on. Whatever oversight exists here comes from the county or city, not from Minnesota.
For this job, that oversight is the permit. Most cities and counties in Minnesota require a permit to install an air conditioner and an inspection once the work is done. That inspection is the check that exists here, since the state itself keeps no record of who is doing this work.

- What size air conditioner does my house need?
- There's no single number that fits every house. The right size comes from a load calculation that looks at your square footage, insulation, window count and direction, and ceiling height, not just a rule of thumb per square foot. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. An undersized one runs constantly and still can't keep up on the hottest afternoons. A contractor doing your installation should run this calculation for your specific house rather than guessing from the old unit's size.
- Should I replace the whole system or just the outdoor unit?
- In most cases you replace both together. The outdoor condenser and the indoor coil are matched to work at a specific efficiency and capacity, and pairing a new condenser with an old coil usually means the system never runs at the rating either piece was built for. It can also void the manufacturer's warranty on the new unit. If your coil is only a few years old and in good shape, ask the contractor to check it against the new condenser's specs before ruling out a partial swap.
- Do HVAC contractors in Woodbury need a state license to work on my home?
- No, Minnesota doesn't issue a state license or registration for HVAC contractors doing residential work. That doesn't mean there's no oversight on your project though. Installing a new air conditioner typically needs a permit from the local building office, and the finished work gets inspected before it's signed off. That inspection is your check that the installation meets code, even without a state license behind the contractor's name.
