Two months of real heat, then it stops

Schenectady only asks a lot of an air conditioner in July and August, when afternoons average 79°F. That is a short season, but the unit still has to be sized and installed right to keep up on the hottest days it sees.

Wind is the bigger risk to outdoor equipment here. The area has logged 188 damaging wind events over the past ten years, along with some hail, so where the condenser sits and how it is secured matters. Any new system also has to meet the federal minimum of 13.4 SEER2, so that baseline is already covered.

What size air conditioner does my house need?
The right size comes from a load calculation, not a guess based on square footage. A contractor measures your windows, insulation, ceiling height, and how much sun your walls get, then works out how many BTUs your house actually needs to cool. An oversized unit cools the air fast but shuts off before it pulls the humidity out, so the house feels damp. An undersized one runs constantly and still can't keep up on the hottest afternoons. Summer afternoons here average 79°F, and with only two months of real cooling need, getting the size right matters more than paying for extra capacity you'll rarely use.
Should I replace the whole system or just the outdoor unit?
If your indoor coil and outdoor unit are different ages or use different refrigerants, replacing just the outside unit usually isn't an option. The coil and condenser are matched to work together, and pairing an old coil with a new condenser can keep the system from reaching its rated efficiency, sometimes voiding the warranty. A contractor can check what refrigerant your system uses and whether the coil will work with newer equipment. If both parts are old, replacing them together is usually the more reliable path.
Do HVAC contractors in Schenectady need a state license to work on my home?
Ask to see a contractor's license and proof of insurance before any work starts, whatever the local rule is. A licensed, insured contractor has to answer for the work, which matters if something goes wrong after the job is done. New central air conditioners installed today also have to meet a federal minimum efficiency of 13.4 SEER2, and a licensed contractor will know how that applies to your installation.
