Heating and cooling companies in Door and Kewaunee Counties are keeping busy as the area experiences a long wave of hot weather.  The daily high temperature has not dipped below 80 degrees since June 28th in Sturgeon Bay and June 25th in Luxemburg. That has kept companies like Ultimate Air in Luxemburg on the road maintaining older units and installing new ones. Owner Jeff Blemke advises people to make sure their outdoor units are clear of dandelion and cottonwood fuzz, their filters inside are clean, and their fingers are off the dial.

Blemke says the AC refrigerant commonly known as R22 is being phased out, which means homeowners must weigh out the costs of adding more of the increasingly expensive product or to invest in a new unit. Extended forecasts show the area may see the 70s return early next week.
