Extreme temperatures require special clothing and can make you shiver or sweat, much like high school proms or choreographed Thriller dances. Control your climate with today's Groupon: for $40, you get an air conditioning or furnace tune-up (a $74 value) and an air-conditioning refrigerant top-off with up to two pounds of Freon refrigerant (up to a $104 value) from Spring Mountain Air (up to a $178 total value). This Groupon is valid only within Greene and Christian counties.

The temperature technicians at Spring Mountain Air repair faulty heating and cooling systems, promptly and efficiently restoring comfort in the midst of extreme weather. During an air conditioning tune-up, the trained climate-controllers clean drain lines and coils so they can regulate temperature and humidity effectively and keep domesticated polar bears comfortable. Then the HVAC expert checks the reflexes of filters, fans, and compressors, and tops off each AC unit with up to two pounds of Freon. During the furnace tune-up option, burners, valves, thermostats, and ignition switches receive a thorough check-up, and heating experts root out and destroy potential carbon monoxide or gas leaks. Technicians also clean the furnace, eliminating cobwebs, dust, and pizza stains left over from nights of experimental cooking.
