Heating in Delaware: what's different
Heating across Delaware depends on the climate (IECC climate zones 4). Furnaces in mixed climates run for several months, and ice storms or cold snaps put sudden load on them. Annual safety checks on burners, venting and heat exchangers are worthwhile.
In Delaware specifically: oil-to-heat-pump conversions. Homes on heating oil often consider heat pumps or dual fuel to cut fuel costs.
Delaware licenses HVACR contractors through the Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners. Common systems in Delaware: Heat pumps, Gas and oil furnaces, Hot-water boilers, Ductless mini-splits.
