3 Reasons to Schedule a Furnace Tune-Up Before Winter Hits

November weather means turning on your furnace for a long winter. If the first cold snap hasn’t hit your local area yet, then now is the best time to get your furnace serviced. Here’s why:

  • The beginning of winter is a busy season for heating contractors and furnace repair companies, which could delay your repair. You don’t want to wait until after the first big storm to get your furnace serviced. Not only can that leave your home without heat during the following low temperatures, a long delay can damage your heating system more or even be dangerous if you have a gas-powered furnace.
  • Servicing your system can help solve problems before they start. Small malfunctions and inefficiencies build up over time, and getting your HVAC checked before you use it regularly can help you catch those problems before your system breaks. Having your furnace serviced means a trained professional checks your ventilation, gas and power connections, and the internal cooling system, which saves you money on larger, preventable repairs.
  • Tune-ups help your home’s air quality. Any air conditioning system in your home collects dust and debris as it circulates air. While changing the filter is one of the best steps you can take to ensuring that allergens are removed from the air and your system isn’t overworking due to poor ventilation, sometimes it’s not enough. Dust can build up in the internal workings of your furnace and mildew that may have built up during the furnace’s dormant season needs to be removed.

Scheduling a tune-up for your furnace before the busy winter season not only helps ensure the system will run once the weather turns, it helps keep your furnace running efficiently. So, contact Cunningham Associates to set up a time to schedule a tune-up.

Short Cycling Furnace Causes: Dirty Flame Rod

Ever wonder what causes a cycling in a furnace? We encourage you to read this article to learn how a dirty flame rod can lead to short cycling.

The Flame Rod 

The flame rod is part of a furnace’s built-in safety system. Its job is to help regulate the state of the gas valve. The idea is that, when ignition is successful, the burner flames will heat up the flame rod, causing it to send a signal to keep the gas valve open. If, however, combustion does not occur, the cold flame rod will soon shut down the gas valve, thus keeping raw gas from leaking out.

Problems 

This is all well and good–so long as the flame rod can do its job correctly. The problem is that, over time, contaminants build up on the surface of the rod. Such contaminants hamper its ability to detect heat. Eventually they will keep it from being able to do its job at all, meaning that the rod, failing to detect heat, will close the gas valve down even when combustion is occurring.

Fortunately, a furnace technician can often resolve this issue simply by giving the flame rod a thorough cleaning with sandpaper or steel wool. If your furnace has been short cycling, it is important to have your flame rod inspected as soon as possible.
