A furnace is the heating element in HVAC systems that regulates the temperature of a home. Many homeowners tend to neglect the furnace and, as a result, end up incurring huge expenses in repair. Some have to get a furnace replacement altogether.

A furnace inspection is vital and can save you repairs worth thousands of dollars. Routine yearly inspections will ensure the furnace serves you several years before replacement. Here are furnace inspections you should do every year for maximum furnace benefits.

Cleaning the Combustion Area

Cleaning the combustion area is crucial for making sure your equipment turns off safely in case of an emergency.

Furnace Venting

A furnace venting system could potentially poison your household if left neglected for too long. You should check the venting system for possible blockages and proper slope. A visual and draft inspection should be done thoroughly to eliminate any dangers.

Safety Conditions

Gas furnaces are capable of blowing up. Test all safety switches for proper operation to prevent overheating and a possible fire outbreak.


A thermostat inspection is vital, mainly if it has been operating for years. Always check the thermostat to ensure it’s in a proper working condition. If necessary, replace the thermostat.

Filter Replacement

A furnace replacement filter ought to be cleaned at least once a year. If the filter accumulated a lot of dirt and got clogged, you should consider replacing it. It should also be inspected for proper installation.

Furnace Ducts

It is vital to inspect the furnace ducts, especially if you have a forced-air furnace. Because the ducts accumulate a lot of dirt, a high-powered vacuum cleaner will work excellently to ensure a dirt-free chimney. After cleaning, ensure you cover the duct so that air doesn’t leak into the furnace.

Check for Leaks

It is recommended that you check your carbon monoxide detectors for any leaks. Carbon monoxide gas could potentially harm you when leaked. Ensure you also inspect the edges of your windows and doors for any spaces. If any, close them using a sealant like caulk.

Check the Drainage Tube

Propane and natural gas furnaces produce water as a by-product. Inspect the drainage tube and ensure it is clear of any residue.

Every homeowner should make it a routine to do a thorough furnace inspection every year. An annual inspection will save you many repair costs, keep your home safe, and enhance your furnace’s functions.
