A homeowner deciding whether a furnace repair is worth doing or a replacement makes more sense should think about how often the burner actually fires. Homes in Delaware run heat about seven months a year, from October through April. That leaves little downtime for the heat exchanger and ignition system to rest between cycles, so wear on those parts shows up sooner than it would if the furnace only ran for a stretch of winter. The compressor outside gets long stretches of quiet by comparison. The burner and igniter carry the load most months, and that is where trouble tends to start first.
Before a new furnace or heat pump goes in, a contractor has to open up what is already there and see what it is working with. Half the homes in Delaware were built in 1987 or earlier (2020-2024 ACS 5-year). That means the ducts, the wiring to the unit, and the space it sits in were all built to match equipment that may have little in common with what is being installed now. A duct sized for one system will not necessarily move the right air for another. The electrical panel may or may not have room for a new circuit. None of that shows up on a spec sheet. It shows up when someone opens the wall or the panel and looks.

A heavier storm record means the outdoor unit works against more than everyday wear. Wind can rock it on its pad, heavy rain can drive water into the cabinet, and hail can dent the fins that keep it cooling properly. A homeowner in a county with a heavier record should have a contractor check where the outdoor unit sits, how well it is anchored, and the condition of the unit itself.
Delaware requires HVAC contractors to hold a state license.
Licenses are issued by the Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners.
