Pilot Light On Furnace Keeps Going Out

By | Uncategorized | No Comments
Why Does The Pilot Light On My Furnace Keep Going Out? A pilot light going out can be an annoying issue to deal with in the cold weather. If you have a furnace that was made in the early 1990's or earlier, chances are you have had to deal with the pilot light going out on your furnace at least once. Why does this happen though? Is there anything that can be done to prevent a furnace repair? Let's find out! Faulty Gas Valve A standing pilot light is really nothing more than a slow and steady flow of gas that helps ignite your furnace when it's time to come on. One of the first culprits that come to mind would be a fault with your furnace's gas valve, possibly with it's power unit. If the gas valve on your furnace is starting to go bad, it might not be providing enough gas to the ignition system to keep your pilot light flame going. Without the proper HVAC tools, a bad gas valve is nearly impossible to diagnose. Improper Flow Of Gas This problem can also be caused by a faulty gas valve. If your furnace's gas pressure is not set properly, the pilot light may not be receiving the correct amount of gas needed to stay light. You are able to adjust the gas pressure via the furnace's gas valve. A proper gas pressure is usually around 3.5" WC. Any deviation from this may cause your furnace's burners to...

How Does A Humidifier Work?

By | Uncategorized | No Comments
How Does A Humidifier Keep My Home Comfortable? Humidifiers are very popular in the winter months when the air becomes dry both outside and inside your home! During the winter, the air in your home can be quite dry and cause damage to both your possessions and your body. A humidifier works with your furnace to keep the water level in the air of your home consistent all winter long. How a Humidifier Works The operation of a humidifier is actually quite simple. The unit itself is attached the the duct work just above your furnace. Inside of the humidifier is a water panel that is moistened with water via a water line. The dry air from the furnace flows over this water panel, collects water, and then is distributed throughout your home. How Do I Control It? You are able to set the desired humidity level in your home via a humidistat. Some of today's higher end thermostats have this included in them so that you don't need two boxes hanging on your wall. In general, an overall humidity level of 35-40% is what you should be aiming for. Anything more than this and you risk condensation forming in your home. Did you know that it's possible for it to rain inside a home if the humidity level is too high? Yep. Why Humidifiers Are Neccessary Dry air is not good for your body or your furniture. If you frequently suffer from static shocks in your home, dry lips,...

What Is A Gravity Furnace?

By | Uncategorized | No Comments
What Is A Gravity Furnace & How Does It Work? Gravity furnaces were one of the most popular ways to heat homes way back in the day. Gravity furnaces were quite popular back in the day. These types of furnaces were installed from the late 1800's to approximately the mid 1900's, before gas and electric furnaces became the standard. If you've ever seen one, you know they can look quite intimidating due to their size! How Do Gravity Furnaces Work? Gravity furnace operation is quite simple. A fuel is inserted into the combustion chamber which would then heat the air surrounding it, and then this air would then rise through the duct work to heat the rest of the home. Heat naturally rises, so there were no blower or motors involved. The original gravity furnaces ran on coal, which would have to be replaced on a regular basis to keep the heat flowing. In essence, it was a giant stove that heated the home at the time. As technology progressed, new fuel sources such as propane, oil, and natural gas replaced the coal to heat the furnace.  Disadvantages of Gravity Furnaces Most gravity furnaces today are due to be replaced just based on their age alone. If that's not convincing enough, here are some other good reasons to replace: Low Efficiency - Today, furnace efficiency starts at 80% and go all the way up to 98%. Meaning at least 80% of the fuel burned is used to heat the home....

Why Does My Furnace Have A Burning Smell?

By | Uncategorized | No Comments
Why Is My Furnace Producing A Burning Smell? Have you started up your furnace for the first time this year only to find it is producing a burning type of smell? This can actually be a normal occurrence! So the weather finally starts to cool down and it's time to start up the furnace for the first time. Yet, when you turn it on, it starts to smell like your house is on fire. What is going on? Let's look at some common scenarios below! Dirty Evaporator Coil During the year, it's normal for your evaporator coil (the coil that sits on top of your furnace used to cool your home via your air conditioner) to become a bit dirty. Despite changing your filter regularly, some dust may begin to accumulate on the coils. When you fire up your furnace for the first time, the hot air then flows over these coils after being heated by your heat exchanger. This hot air can begin to burn off some of this dust, hair and other particles that may have accumulated on your coil over the summer months. Although you will notice this smell the first couple times your furnace runs, the smell should begin to dissipate rather quickly over time. It is a good idea to have your evaporator coil cleaned at least once every couple years to prevent costly air conditioner repairs. Dirt Air Filters This one is simple enough. Check your furnace filter to make sure that it is...
