Thermostat

While thermostats rarely fail outright, they can degrade over time as mechanical parts stick or lose their calibration. Older units will send faulty signals if they’ve been knocked out of level or have dirty switches. To recalibrate an older unit, use a wrench to adjust the nut on the back of the mercury switch until it turns the system on and, using a room thermometer, set it to the correct temperature. Modern electronic thermostats, sealed at the factory to keep out dust and grime, rarely need adjusting. However, whether your thermostat is old or young, the hole where the thermostat wire comes through the wall needs to be sealed, or a draft could trick it into thinking the room is warmer or colder than it really is.

Blower

Tuning up the distribution side of a forced-air system starts with the blower. The axle should be lubricated, blades cleaned and lower motor checked to insure the unit isn’t being overloaded. The fan belt should be adjusted so it deflects no more than an inch when pressed. Every accessible joint in the ductwork should be sealed with mastic or UL-approved duct tapes. Any ducts that run outside the heated space should be insulated.

What are some preventative maintenance things I should be aware of? 

With the proper attention, heating and cooling systems can keep you comfortable year-round. Heat pumps and oil-fired furnaces and boilers need a yearly professional tune-up. Gas-fired equipment, on the other hand, burns cleaner and can be serviced every other year. A close inspection will uncover leaks, soot, rust, rot, corroded electrical contacts and frayed wires. In furnace (forced-air) and boiler (hot-water) systems, the inspection should also cover the chimney, ductwork or pipes, dampers or valves, blower or pump, registers or radiators, the fuel line and the gas meter or oil tank — as well as every part of the furnace or boiler itself.

Next, the system should be run through a full heating cycle to ensure that it has plenty of combustion air and chimney draft. Finally, cleaning the burner and heat exchanger to remove soot and other gunk will prevent such buildup from impeding smooth operation. For the burner, efficiency hinges on adjusting the flame to the right size and color, adjusting the flow of gas or changing the fuel filter in an oil-fired system. A check of the heat pump should include an inspection of the compressor, fan, indoor and outdoor coils and refrigerant lines. Indoor and outdoor coils should be cleaned, and the refrigerant pressure should be checked
