The best thing you can do for your furnace and vents is to schedule an annual maintenance appointment with a qualified HVAC technician. The technician will perform a thorough examination of your system, inspect it for wear and tear, and look for potential problems. All of this keeps your system in working order and prevents costly repairs by getting ahead of them through a warranty claim or while the repair is still inexpensive. Here’s what you can expect during routine maintenance for your heating system.
Inspection of Moving Parts
A furnace has quite a few moving parts that are crucial to its operation. They include fan belts, bearings, and fan motors. Your furnace can have multiple fans depending on its design, and those motors have bearings and sometimes belts. And because they’re moving parts, they can break with wear and tear. Routine maintenance makes sure these parts are working and ready for the upcoming season. If a part is damaged, the technician can swap it out for a new part. The tech also lubricates the bearings to reduce friction along with any other parts that need oil.
Check the Pilot and Gas Pressure
The function of the pilot light is to turn on the burners to produce heat via the thermocouple. Sometimes the tip of the pilot light fills up with soot or corrodes. It can also lose height, which means it will not ignite the furnace when called upon. This can be caused by poor gas pressure preventing the thermocouple from igniting. The technician goes over all of these parts to make sure the pilot light is performing according to manufacturer standards. If it’s not, he or she can troubleshoot the problem and make the appropriate repairs.
There are a number of reasons why a pilot light might lose height, and they’re not always obvious. Don’t feel as if you should have done something to prevent the pilot light from malfunctioning. Rather, be relieved that you brought in a technician to do routine maintenance on your furnace and prevented the problem from getting worse.
Vacuum the Burners
Your furnace has multiple burners to supply heat to your home, and they collect soot with use. Burning natural gas as a fuel creates soot due to impurities. Natural gas is one of the cleanest-burning fuels, but that doesn’t mean it does not have contaminants. When the gas burns, it leaves deposits behind that build up and clog the burners, reducing their performance. The technician can assess your burners to determine if they need to be vacuumed. If you haven’t touched the furnace since it turning it off in the spring, the chances are good that the burners need vacuuming.
These are some of the things you can expect an HVAC technician to do during a routine maintenance of your furnace. The technician’s inspection helps keep your furnace in the best possible condition while also saving you money in the form of improved performance and preventive maintenance.
