Three months of real heat, and a new minimum to meet

Spring Valley only asks for cooling from June through August, but those afternoons average 82°F. A new system has to handle that load for three months straight, then sit idle the rest of the year. That on and off pattern matters as much as the peak heat does.

Any new central air conditioner installed today has to meet 13.4 SEER2, the federal efficiency minimum. Rockland County has also seen its share of wind, 42 damaging wind events over the past ten years, so whatever gets installed outside needs to be set and secured with that in mind.

What size air conditioner does my house need?
The right size comes from a load calculation, not a rule of thumb based on square footage. A contractor measures your windows, insulation, ceiling height, and how much sun your walls get before landing on a number. Too big and it cools the room fast but never runs long enough to pull the humidity out. Too small and it runs constantly all summer without catching up on the hottest afternoons.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit are different ages or different efficiency levels, replacing just the outdoor unit usually causes problems. The two are matched at the factory to work together, and pairing a new condenser with an old coil often means the system never reaches its rated efficiency. A contractor can check the age and condition of both and tell you whether the coil is worth keeping. If the indoor coil is old too, or if it's not compatible with the new unit's refrigerant, replacing both at once is usually the better call.
Do HVAC contractors in Spring Valley need a state license to work on my home?
Yes. Anyone installing or servicing central air conditioning needs a state contractor's license. Ask to see it before work starts, and check that it covers HVAC work specifically. A licensed contractor also carries the insurance that protects you if something goes wrong during the install.
