Keep on Top of Things with This Important Furnace Checklist

With the cooling season getting close, it’s important to make sure your furnace provides you with dependable heat. The following furnace checklist can help ensure that your Yuma home stays warm throughout the colder part of the year.

Air Filter

Replace your HVAC’s air filter with a new one before using your furnace. Make sure you change it every month or so during the fall and winter as needed. Having a new air filter on your furnace checklist helps keep your indoor air quality in good condition while your furnace is running.


Checking your thermostat is an important part of ensuring that your heating system works properly. Test your thermostat to make sure it’s working right.


Have HVAC technicians clean the burners in your furnace as part of your furnace checklist. This maintenance task helps keep your furnace working safely while also lowering the risk of damage.

Heat Exchanger

A cracked heat exchanger in your heating system puts you at risk of a carbon monoxide leak. Have an HVAC professional inspect your furnace’s heat exchanger to see if it’s in good shape or if it has any cracks or other signs of damage.

Fan Switch

The fan switch in your furnace should be adjusted as needed to make sure your heating system cycles properly. If it’s not adjusted, your furnace might end up running more often than needed, leading to higher energy bills.

Gas Line

HVAC technicians should definitely check the furnace’s gas line as part of your furnace checklist to make sure there are no leaks or damage.


The pilots for your furnace should be inspected and cleaned. Debris in or around the pilots, or pilots that aren’t working properly, could cause your heating system to stop working.

Belts and Pulleys

During routine HVAC maintenance, technicians should check and adjust the belts and pulleys in your furnace. This helps ensure proper airflow, which can reduce the risk of having your furnace break down.
