Four months of real heat, every year

Manhattan asks for cooling from June through September, and summer afternoons average 84°F. A new system has to handle that stretch every year without strain.

Any new central air conditioner installed today has to meet 13.4 SEER2, the federal efficiency minimum that took effect in 2023. That's the baseline, not an upgrade you have to ask for.

What size air conditioner does my house need?
It depends on your home's square footage, ceiling height, insulation, window area, and layout, not just the size of the space. A unit that's too big will cool the air fast but shut off before it pulls the humidity out, so rooms feel damp. A contractor will run a load calculation on your actual home to get the right size, and with summer highs here averaging 84°F, getting that number right matters more than guessing based on square footage alone.
Should I replace the whole system or just the outdoor unit?
If your indoor and outdoor units are matched and the indoor coil is still in good shape, replacing just the outdoor unit can work. But if the system is old, a mismatched pair runs less efficiently and can wear out sooner, since the indoor and outdoor components are engineered to work together. A contractor can check the age and condition of both parts and tell you whether a full swap or a partial one makes sense for your setup.
Do HVAC contractors in Manhattan need a state license to work on my home?
Yes, HVAC contractors need to be licensed to install or service central air conditioning systems. Ask to see the license before work starts, and confirm it's current. A licensed contractor also carries the insurance that protects you if something goes wrong during the job.
