10 Things to Check Before Turning on Your Furnace

Now that we are entering the cooler months, it’s about time to turn on the heat for the first time since last season. But before you go and turn it on, there are some things you need to do first. Your furnace could have developed some small technical problems since being left unused through the summer and may need to be calibrated or inspected.

It is always a good idea to have a technician carry out a pre-run furnace inspection to ensure that your furnace is running efficiently and will heat your home reliably throughout the winter months.

Here are 10 tips from our team at Super Heat & Air to do before turning on the heat this season!

#1. Check that Your Furnace Has Electrical Power

Check your fuse or breaker box for any blown fuses or tripped breakers before turning your furnace on, as this could signal a problem with the electrical system of your home. If you are unsure of the current state of your electrical system, call in a licensed electrician to inspect it to ensure that your family and home are safe.

#2. Make sure that the Unit’s Power Switch is “On”

There are many cases where a furnace might have been mistakenly switched off or even switched off on purpose but forgotten about throughout the summer months. Look for the power switch on your unit, which may be in a metal enclosure. If you are opening an electrical component, we recommend shutting off power at the breaker. If the switch is off, switch it to on, and you should be all set!

#3. Check for Obstructions in the Exterior Intake and Exhaust System

Perform this check while your furnace is in operation. Check for debris such as windblown leaves, insects, and rodent nests that may have caused a blockage in the airways of the system.

Take caution: these blockages can prevent proper airflow but can also cause excessive heat and carbon monoxide gas to build up.

#4. Check the Thermostat Settings

Make sure that the thermostat is set to “heat” and that the temperature setting is set to a temperature that is sufficient to start the furnace. You may smell a slight “burning” smell when you first turn on the furnace, but this is normal. It is dust burning off the coils.

#5. Check the Thermostat Batteries

If your furnace has a programmable thermostat, all you need is a simple battery. You will often be warned by a flashing light when the battery is getting low. It can be tricky locating the batteries on some thermostats, so if you are having any problems replacing the batteries, call our team at Super Heat & Air!

#6. Check the Air Filter

Check your furnace air filters to ensure that they are not clogged. It is recommended to change your furnace filters every 3 months, and sometimes more often in humid climates or if you have pets. Changing your filters regularly can improve the life of your unit and ensure that it is running at optimal efficiency all season long.

#7. Have Your Air Ducts Cleaned

Having a clean air duct system guarantees that the air quality in your home is optimal and enhances the efficiency of your entire HVAC system. We offer duct cleaning services at Super Heat & Air that will ensure that every square inch of your ductwork is clean and clear of all allergens!

#8. Test Safety Detectors

Before you fire up your furnace, make sure that your smoke and carbon monoxide detectors are working properly. Change the batteries at least once a year to ensure that they are functioning during an emergency.

#9. Check Your Unit’s Gas Supply

Natural gas can be fatal, so do not handle or tamper with any of the components of your gas supply line or the pilot line of your furnace. If you smell gas or suspect a gas leak, call 911 immediately.

#10. Get Professional Maintenance Performed

We recommend getting your furnace inspected and tuned up yearly by a licensed heating technician. Not only will this keep it running at peak efficiency, but it will also extend the life of your system. By staying proactive, you can reduce the risks of costly breakdowns and repairs.
