Two months of real heat is still enough to matter

Amherst Town gets two months of cooling weather, July and August, with afternoons averaging 80°F. That is a short season, but it is a demanding one, and a new air conditioner has to handle those peak afternoons without strain from the day it goes in.

Hampshire County has also seen its share of hail and wind over the past ten years, 34 hail events and 218 damaging wind events since 2015, with hailstones up to 1.75 inches. An outdoor unit sits exposed to all of that, so it needs to be installed and sited with that in mind. Any new central air conditioner installed today also has to meet the federal efficiency minimum of 13.4 SEER2.

What size air conditioner does my house need?
There's no single answer without a proper load calculation done on your house. A contractor measures your square footage, but also your insulation, window count and placement, ceiling height, and how much shade your house gets, since two homes the same size can need different sized units. Guessing on size backfires either way. Too big and it cools the air fast without pulling out humidity. Too small and it runs constantly without keeping up on the hottest afternoons. Ask the contractor to walk you through the load calculation so you know the number is based on your house, not a rule of thumb.
Should I replace the whole system or just the outdoor unit?
In most cases you replace both the outdoor unit and the indoor coil together. The two are matched to work at a specific efficiency and capacity, and pairing a new outdoor unit with an old coil usually means you lose the efficiency gain you're paying for. It can void the warranty too. A contractor can check the age and condition of your indoor coil and tell you whether it can stay or needs to go. If the coil is old enough to be near the end of its life anyway, replacing both at once avoids paying for labor twice.
Do HVAC contractors in Amherst Town need a state license to work on my home?
Ask to see a contractor's license number before any work starts, and check that it's current. A licensed contractor also carries insurance, which matters if something goes wrong during installation. If you're not sure what's required for your job, the contractor can tell you what license and permits apply to it.
