5 Furnace Warning Signs You Should Know


Over time, your furnace may develop issues that can leave your Grand Prairie, TX home unsafe and really uncomfortable. Good thing that there are signs that tell you that something is wrong with your heating unit. Once repairs are done, you can save your furnace and home as well.

Keep an eye on these five (5) warning signs of furnace malfunction.

Old Age

The average lifespan of a typical furnace is 16 to years. If yours has reached this bracket or even older, it is wise to start shopping for a new unit. When your furnace begins to fail or falter in one way or another, it means that some components have worn out that require repair or replacement. Check your user manual or coordinate with its manufacturer regarding the age of your furnace.

Increased Energy Bills

Furnaces that have not been properly maintained lose their efficiency through the years. As a consequence, they have to run longer than normal to provide the heat based on your comfort needs. This is why your electric bills are continuously going up.

Disturbing, Unfamiliar Noises

Those strange sounds that you hear from your furnace are indications of an issue in the unit. Spare some of your time observing your furnace for banging, popping, rattling or squealing noises. These sounds mean that something in the blower or other parts of the system are damaged or worn out. Get this issue fixed by calling your trusted HVAC contractor immediately.

You’re Getting Sick More Often

It’s not always that you get flu or cold even if you stay most of the day indoors. But with a malfunctioning furnace, you are more prone to illnesses especially with clogged filters and cracks on the heat exchangers. Cracks that developed in the heat exchanger might cause carbon monoxide to leak resulting in flu-like symptoms, headaches, nausea, and other similar health problems. Have your furnace inspected by an expert technician to detect and resolve existing and future issues on the unit.

Changes in Flame Color

Your furnace’s burner should only produce a blue flame. If you see any colors than blue like yellow or orange flame, it means that the unit is seriously damaged. Yellow flame has other implications such as leaks in the chimney or vent, rust in the pipes, carbon monoxide diffusion and more. Give your technician a call after you noticed a yellow flame on the burner.

How Much Heating Oil Will You Use During Winter?


It’s not every day that you ask, “how much heating oil will I use throughout the cold season?”, “does my furnace tank have enough fuel?” This winter, all homeowners in Grand Prairie, TX should make sure that there is an adequate amount of heating oil in their furnace tank. Want to learn how to calculate your heating oil consumption? Check out this guide for information.

Monthly Heating Oil Costs Calculation: Gallons & Average Usage

Many factors can affect your monthly heating oil consumption including your lifestyle, room temperature settings, the age of your heating system and maintenance. But, making calculations can be as easy as these guidelines below.

  • Check the manufacturer’s plate on the burner

The number near the burner indicates the capacity specifications of the tank in gallons per hour. You may also check the complete information on the nozzle.

  • Look into your previous heating-oil bills

Check the volume of oil consumed from the past winters. This way, you can easily determine how much you are likely to spend this year. Also, consider the weather last winter. If it was not as cold as today, then add a little more volume of oil for your usage this year. To get your average heating oil consumption per month, get the sum of your oil usage for 12 months then divide the answer by 12.

  • Refer to the average gallon consumption of oil-burning furnace per hour

An oil-burning furnace commonly consumes an average of 0.8 to 1.7 gallons of oil per hour during operation. These numbers may change depending on some factors like the design and age of the unit. Some models may consume more or less oil than the average.

Expert Ways to Lower Your Heating Oil Consumption

  • Invest in high-quality fuel oil.
  • Get annual furnace check-ups and maintenance. Clean the filters, nozzles, burner, and other essential parts of the furnace as often as possible.
  • Buy smart thermostats to help you control your fuel oil usage.
