Rockland asks a lot of a heating and cooling system

Winter nights here average 16°F from December through February, and a new furnace or heat pump has to hold a house steady against that, night after night, for nine months straight. September through May, something in your house is running to keep it warm. That is most of the year the system is on the clock.

Summer only asks for one month of cooling, with afternoons averaging 74°F, but the equipment still has to be sized right for it. More than half the homes in this area heat with fuel oil, so if you are switching to a heat pump or adding one alongside your existing system, that is a real change in how the house is heated, not just a swap of one box for another. And with over half of Maine households losing power for 24 hours or more at some point in 2024, and 45 winter storms on record here over the past ten years, what you install and how it is installed matters as much as what it is.

When should I replace my HVAC system?
Once repairs start coming more often, or a repair costs enough that a new system starts to look like the better deal, it is time to replace it rather than fix it again. Age matters too. If your furnace or air conditioner is old and just broke down, that breakdown is usually the sign to stop patching it. Homes here need heat from September through May, so replacing before a cold snap beats replacing during one.
Should I replace my furnace and air conditioner at the same time?
If both are old and one just failed, replacing them together often makes sense, but it depends on the condition of each one. A furnace and AC installed at the same time tend to wear out around the same time too, so if one is failing the other may not be far behind. They also share the same ductwork and, in many systems, the same blower, so pairing a new unit with an old one does not always work as well as replacing both together. A contractor can look at each system and tell you whether one or both need to go.
What happens during an HVAC installation?
A contractor removes the old equipment first, then sets the new furnace, air conditioner, or both in place and connects them to your ductwork, gas line or electrical circuits, and condensate drain. They check that your ducts and vents are sized right for the new equipment, since a bigger unit on the same ducts can cause problems. Once everything is connected, the system gets tested and the settings adjusted so it runs the way it should. With homes here needing heat nine months of the year, ask what checks are included for the furnace side, not just the air conditioner.
