A compressor starting up after months of sitting idle carries more risk on its first run than one that has been cycling regularly. Homes in Delaware run cooling about three months a year, from June through August. That concentrated window means a sizing or installation error surfaces fast. A unit that cannot hold capacity on a hot afternoon in late June has no quiet shoulder season ahead of it to hide in, and the homeowner finds out exactly when demand peaks. A contractor who knows this accounts for it before the quote, not after the first callback.
A quote for a mini split install starts with what a contractor can verify, and in Delaware that list is longer than the equipment spec sheet. Half the homes in Delaware were built in 1987 or earlier (2020-2024 ACS 5-year). A house built before modern HVAC loads were standard may carry electrical service that was sized for far fewer draws than run today. That means the panel gets opened and read before any unit gets specified, not after. Ductwork, if it exists, gets the same treatment: condition and routing have to be confirmed, not assumed from the age on a permit.
Does your county put extra stress on HVAC equipment?

A condenser sitting outside faces whatever the sky delivers: driving rain, heavy snow loads, ice that seals coil fins, summer heat that pushes a system to its limit for weeks at a stretch. Where a county sits in this ranking shapes how a unit should be sized, how it should be mounted, and how often it needs to be looked at. The contractor you are matched with knows that calculus and applies it before any work begins.
