Dover-Foxcroft doesn't ask much of an air conditioner

Summer afternoons here average 74°F. That's mild, and it means a new air conditioner in Dover-Foxcroft isn't fighting the kind of heat that pushes a system hard for months at a stretch.

Still, whatever gets installed has to meet the federal efficiency minimum of 13.4 SEER2, and it has to hold up outside. This county has seen 61 damaging wind events and 16 hail events over the past ten years, with hail up to 2 inches. A good installation accounts for that outdoor unit sitting through real weather, not just the temperature it's cooling against.

What size air conditioner does my house need?
The right size comes from a load calculation, not the square footage of your house alone. A contractor looks at your windows, insulation, ceiling height, and how many rooms get direct sun before recommending a size. An oversized unit cools the air fast but shuts off before it pulls the moisture out, so the house feels clammy. Summers in Dover-Foxcroft run mild, with afternoons averaging 74°F, so most homes here need less cooling capacity than the same house would in a hotter climate.
Should I replace the whole system or just the outdoor unit?
If your furnace or air handler still has years left in it, replacing just the outdoor unit can work, but the indoor and outdoor parts need to be matched for the system to run the way it was designed to. An old indoor coil paired with a new condenser can undercut efficiency and shorten the life of the new equipment. A contractor can check the age and condition of what you have and tell you whether a matched pair is worth doing now or if a partial swap is a safe bet.
Do HVAC contractors in Dover-Foxcroft need a state license to work on my home?
Ask to see a contractor's license before any work starts on your home. A licensed contractor can show you their license number and stands behind the work they do. If someone can't produce one, that's reason enough to call someone else.
