AC & Furnace Check-up



A furnace check-up or tune-up is much like a visit to the doctor or taking your car to a mechanic. However, specifically in the case of your home, a furnace check-up consists of the following steps:
Inspect thermostat for proper operation.
Inspect filter and change or clean as needed.
Check all electrical components and controls.
Oil motors as needed.
Inspect heat exchanger for possible cracks. A crack in the heat exchanger will introduce carbon monoxide into the living space.
Check air flow. If diminished, it may be necessary to clean the evaporator coil.
Check air fuel mixture, where appropriate.
AC & Furnace Maintenance While having your furnace tuned and checked each year before the cold weather is wise practice, there are also a few things you can do to assure that your furnace is operating properly, safely, and to its fullest capacity. The very first thing to check before turning on your unit is to make sure nothing flammable has been stored next to the furnace over the summer. Many, many people have set their weedeaters, lawnmowers, and gas cans against their furnace in the garage. This is just asking for a fire or an explosion. Run your heater for a few minutes before you actually need it. Waiting until the first cold morning to discover it isn’t working will land you at the bottom of a waiting list before a heating and air specialist can come to fix it. Change the filters regularly. Dirty filters restrict air flow, reducing efficiency and worst case, can cause the heat exchanger to overheat. Disposable fiberglass filters should be replaced. Electrostatic or electronic filters need to be washed regularly. Be sure all access panels are secure, with all the screws in place. Be sure the thermostat is set in the heating mode. Just setting the dial above room temperature will not activate the heat if still set in the air conditioning mode.
