Is your home heating system ready for winter? Watch our video to see HVAC preventive maintenance steps for fall and learn how to get your furnace ready for the cold weather.

Fall is officially in the air. Along with football, back to school and cozy sweaters, the change in season means it’s time to think about calling the experts for an HVAC checkup.

A professional preventive maintenance check will make sure that when the time comes to switch your unit from cooling to heat, your furnace will keep you warm during the cold winter months ahead. But that’s not the only benefit — regular HVAC maintenance can help your furnace run more efficiently and prevent costly repairs down the road.

Lennie Arroyo, HVAC service district manager for Sears Home Services, gives the inside scoop on the inspection process.

Sears Home Services Fall HVAC Preventive Maintenance Check, Step by Step


The first step is to check the thermostat inside your house to make sure it’s properly attached and working correctly.


Next, the technician will check the furnace to ensure that there’s adequate airflow, especially if your unit is located in a closet. It’s important that nothing obstructs the unit.


Your technician will safely remove the vent and check the inducer motor and gas valve connection and make sure the thermostat wires are nice and tight. In addition, he or she will look for burned wires and loose connections.


Once the wiring is inspected, the technician will then check to make sure your burners are on and the flame is a bright blue. If the flame is orange or weak, that’s a sign that your unit needs to be serviced.

Amp Draw

He or she will then use a multimeter to measure the amp draws in the inducer motor and check the blower motor to ensure that heat can circulate.


Next, your technician will check the filter and change it if it’s dirty — a dirty filter makes your unit run less efficiently.

Carbon Monoxide

Your technician will also check if any carbon monoxide is detected. This odorless gas can be fatal.


Does the motor need to be lubricated? If so, the experts at Sears Home Services do so as part of the check.


The last thing your technician will do is carefully clean the unit with a vacuum cleaner to help it run properly.
