It takes about a minute.
Four months of real work, then a long rest
Your air conditioner in the Bronx has a short, hard job. June through September, summer afternoons average 83°F, and that is when the unit has to keep up. The rest of the year it mostly sits.
A new system installed today has to meet a federal minimum of 13.4 SEER2, so whatever goes in will be built to handle those four months efficiently. Wind is the bigger risk to outdoor equipment here. The area has logged 20 damaging wind events over the past ten years, against just 2 hail events, so a unit set where it won't take a direct hit, and secured well, holds up better than one left exposed.

- What size air conditioner does my house need?
- The right size depends on your square footage, how much sun your walls and windows get, your insulation, and your ceiling height, not just the size of the room you want to cool. A contractor works this out with a load calculation, not a guess based on tonnage per square foot. Too big a unit cools the air fast but never runs long enough to pull the humidity out, and too small a unit runs constantly and still can't keep up on your hottest afternoons. Summer afternoons here average 83°F, so an undersized system has real hot days to struggle against.
- Should I replace the whole system or just the outdoor unit?
- If your indoor coil and outdoor unit are different ages or different efficiency ratings, replacing only the outdoor unit can leave you with a mismatched system that never performs the way either piece is rated to. Refrigerant type is another issue. Older outdoor units may use a refrigerant that current indoor coils aren't built for, so pairing new with old isn't always possible even if you wanted to. A contractor can check whether your indoor coil will work with a new outdoor unit, and tell you whether replacing both is what your system actually needs.
- Do HVAC contractors in Bronx need a state license to work on my home?
- Ask to see a contractor's license number before any work starts, and confirm it's current. A licensed contractor also carries insurance, which protects you if something goes wrong during the installation. A contractor who is reluctant to show either one is a reason to keep looking.
