Dallas summers are long and hot enough that air conditioning counts as essential, and many homes run air handlers and ductwork in hot attics, which strains equipment.
Demand spikes when the first stretch of 100-degree days arrives, and every contractor in the metroplex raises bids at the same time. Winters are short, but cold snaps still bring heat pump and furnace calls, and the February 2021 freeze is still remembered.
Replacement decisions are shaped by the move to newer refrigerants, which gives owners of older units a reason to ask about options. Texas licenses air conditioning contractors through TDLR, and homeowners do look for the number.
