In-home heating systems have eliminated the dangers of keeping warm, such as burning wood indoors and curling up beneath hibernating-bear rugs. Safely stay warm with today’s Groupon: for $59, you get a furnace tune-up and cleaning from Onsite Heating & Air (a $140 value).

Onsite Heating & Air's temperature regulators ensure indoor warmer systems perform in peak condition throughout the blustery winter months. Following a courteous introduction and safe disposal of ceiling icicles, technicians dive into the heart of the home’s furnace to visually inspect heat exchangers and belts for signs of wear and cracking. A flue examination ensures ductwork remains free of debris and nesting skunks before blower components receive a thorough scrubdown, preventing allergens from afflicting fresh air. The furnace fixers inspect standard air filters and adjust airflow and fan controls to optimize temperature output, potentially lowering energy costs. Once the high-limit and accompanying safety controls have been scrutinized, technicians sign off on a winter-ready system that will effectively reduce invading snowmen to puddles of spring water.
