Working air conditioners are integral facets of summer comfort, without which June ice sculptures, July snowmen, and August Santa Clauses would become extinct. Protect popsicle populations with today's Groupon: for $49, you get a home air-conditioner tune-up for homes within the Kingston city limits from 21 Degree's One Hour Heating & Air Conditioning (up to a $111.87 value).

The qualified technicians at 21 Degree's check, test, and calibrate home air-conditioning units to ensure proper operation and to decrease the likelihood of costly future repairs. The service lasts about an hour, depending on the unit model and how much it squirms, and starts with an inspection of the thermostat, filter, service fan motor, and fan blades. Next, an air aficionado tests blower and compression operation, clears the drain lines, and inspects the contactor and capacitor. Indoor and outdoor temperatures and other unit segments undergo a precise measurement, which aids in bringing forth an era of cool contentment not seen since snowballs started getting massages. Technicians can book appointments Monday–Friday and recommend that dwellers reassess their air conditioners once a year, much like the height of growing children or the surface area of yearbook photos.

Though 21 Degree's One Hour Heating & Air Conditioning sometimes features a discounted price online, this Groupon still offers the best deal available.
