Arizona is well known for its hot summers and mild winters. It can be normal to experience five months of 100-degree temperatures. That means your AC unit will operate around the clock to meet your comfort level. However, do not underestimate the low temperatures during the winter months. It is common for the temperatures to drop into the low 40s. Affordable Comfort highly recommends that you be prepared for those temperature differences with regular heating and a/c system maintenance. We offer a variety of “custom fit” maintenance programs to accommodate your needs.
