What Actually Happens During Furnace Maintenance?

pressure-gauge-on-boilerWe’ve talked recently on this blog about the need for annual furnace maintenance as well as some warning signs that your furnace needs prompt repair. But if you still haven’t scheduled furnace maintenance, or you’ve got an upcoming appointment, you might like to know more about exactly what the process entails. 

Before We Begin

Your heating system is complex, with many components, including things like gas lines and electrical elements that can only be safely handled by a professional. There are some things you should do yourself, though.

First, keep your furnace itself and the surrounding area clean and free of debris. For a traditional furnace which likely lurks in your basement, this means wiping down dust and sweeping away cobwebs, as well as making sure storage boxes or any other basement items are kept out of the way of the furnace. If you have a heat pump with an outdoor unit, you should rake away leaves and other debris and make sure any nearby shrubbery is trimmed so there is clear space around the unit. 

Next, change your air filter. This should occur about every three months during the heating season, with a few exceptions. During extremely cold weather with more intensive furnace use, or if there has been additional contamination of your air such as severe pet shedding or dust from nearby construction, you should change it every month.

The Maintenance Process

Your technician will also change the filter, though they’ll be delighted to find you’ve been changing it yourself. They will also give the interior of the furnace a thorough cleaning. The drain pan for condensation will be checked, and cleaned as needed. And all moving parts such as motors and fans will be lubricated, so they move freely and smoothly and don’t cause wear and tear or overheating.

Your technician will also check all electrical components of your heating system. The electrical controls and thermostat will be tested to make sure they are giving accurate readings and responding as they should. All wiring will be checked and loose connections tightened. Your technician will measure voltage and amperage to make sure everything is at the appropriate levels. And, if it is an electric furnace, the technician will inspect and clean the heating element.

If it is an oil or gas furnace, all connections will be checked to make sure you’re not running the dangerous risk of fuel leaks. And the technician will inspect the burner itself. This is particularly critical because if fuel is not combusting properly, carbon monoxide can be produced. 

In short, your technician will make sure all parts of your heating system are clean, moving freely, and operating efficiently, as well as giving you freedom from worry about the dangers of electrical or gas hazards. Having your furnace maintained has significant benefits for your safety, your peace of mind, and even your wallet. An efficient furnace uses less energy and costs less to run, and a well-maintained furnace will last longer than a neglected one, saving you from the expense of replacing it.
