Six months of cooling in Brookhaven summers
Your air conditioner runs from May through October here, and on summer afternoons it's working against a average high of 91°F. That is a long stretch of steady runtime, season after season.
Brookhaven has also seen its share of hail and wind over the past ten years, with hailstones up to 2.5 inches recorded. An outdoor condenser sits exposed to that. If you're installing new, a unit built since 2023 has to meet 14.3 SEER2, the federal efficiency minimum, so whatever goes in will be built to handle the load these summers put on it.

Mississippi requires HVAC contractors to hold a state license.
The license is held by the contractor, not by the job, so this contractor was tested and put on record by the State Board of Contractors before this job ever came up. It's the contractor's name attached to that license, not a crew member's or a salesman's.
For this install, the license accounts for who is doing the work, not for whether this particular job gets checked. That comes from the local building office. In most cities and counties, putting in a new air conditioner needs a permit, and the work gets inspected once it's done.

- What size air conditioner does my house need?
- It depends on your square footage, your ceiling height, how much shade your house gets, and how well it's insulated. A contractor works this out with a load calculation, not a chart based on home size alone. With summer afternoons here averaging 91°F, getting the size right matters more than in milder climates. Too big and it cools the air fast but never pulls the humidity down. Too small and it runs constantly all summer and still can't keep up on the hottest days.
- Should I replace the whole system or just the outdoor unit?
- In most cases, if the outdoor unit needs replacing, the indoor coil should go with it. New units come with a different refrigerant than what's in older systems, and matching a new outdoor unit to an old indoor coil often doesn't work efficiently, if at all. A contractor can check whether your indoor coil is compatible before deciding. Age matters too. If the whole system is old, replacing just the outdoor unit usually just means replacing the coil sooner than you'd like.
- Do HVAC contractors in Brookhaven need a state license to work on my home?
- Yes. Mississippi requires HVAC contractors to hold a state license, issued through the State Board of Contractors. That license covers the contractor as a business, not each individual job. Installing an air conditioner will also likely need a permit from the local building office, with an inspection once the work is done.
