Furnace Tune-Ups & Maintenance

The team at Jansen Heating, Air Conditioning & Electrical knows how much you rely on your furnace through the Illinois winter.

Regular tune-ups and preventative maintenance reduces the need for repair over the life of your furnace. Fewer repairs mean your furnace costs less to operate. Not only that, a properly maintained furnace runs more efficiently for longer, sometimes lasting twenty years or more. By cleaning, inspecting connections, lubricating moving parts, checking system controls and ductwork, the specialists from Jansen will save you money on both utility bills and system breakdowns.

  • Check return & air filter
