Gas Furnace Number 1 Problem Flame Sensor - What is the number one trouble call for gas furnaces? We went through our records and found the number one problem for a gas furnace troubleshooting call is the flame sensor. If the flame sensor is not functioning as designed it will prevent the gas furnace from firing. The behavior of the gas furnace when the flame sensor fails will be trial for ignition and eventually a lockout. This is a common problem. So, how do you repair this problem and get your heat working again? (more…)
How Hot Surface Ignition Works - Hot surface ignition is a method of lighting a gas furnace. It is used in many different types of gas furnaces in use today. You may be wondering how hot surface ignition works?
Therefore we decided to write an article on it so you can understand how hot surface ignition works. We will describe the different types of hot surface ignition, including the gas furnace sequence of operation for different types of hot surface ignition. (more…)
Paul, Last year my husband and I purchased a brand new gas furnace and air conditioner split system. We followed your advice and want to thank you. It is much improved over the old system and the utility bills are lower. Everything went smoothly with the contractor and installation.
It’s been a little cold at night and we’ve been running the gas furnace at night. This morning we found water all over the floor near the furnace. I never thought furnaces could make so much water. Can you please advise? Why is my furnace leaking water, Paul? (more…)
The pilot going out is a common occurrence for those that have water heaters or older gas furnaces. These types of heat appliances utilize pilot lights to light the main burner.
That can turn into a nuisance for both maintaining heat or hot water. If it’s the water heater you have to re-light the pilot and then wait for the water heater to heat the water. The same for a furnace.
You have to light the pilot light and then wait for the furnace to heat the home to a comfortable temperature. There are a few main reasons why this occurs, and we will describe them here. We want to help you find the solution to your problem because we know it can cause discomfort.
It is frustrating to have to continually re-light the pilot light so you can get hot water or heat. Is it the gas valve and thermocouple or something else? (more…)
Furnace Smells Like Gas - Hello, I have a gas furnace in my house for home heating. It is in the attic. My wife and I were in the attic reorganizing some things, and the furnace was off. On occasion, I got a whiff of gas.
I know natural gas is odorless, but they add an odorant to the gas so you can smell it. It is a rotten egg smell, and that is what I smelled in our attic. Can you please advise us on what to do? Thanks!! And I enjoy reading your site to help me understand my HVAC system. Good Info!!!!
New Thermostat Problem or Gas Furnace Issue - Richard, I have a natural gas thermostat I just replaced this with a new Honeywell thermostat.

Furnace Blower Fan Wont Turn Off - Hello Richard, I have a problem with my furnace where the indoor blower will turn off. My furnace seems to be heating okay it is just the blower will not shut off. It is an older furnace, and I have checked the thermostat settings. Its setting is automatic with the fan switch part set to automatic, so I know that is not the problem causing the furnace blower not to shut and run continuously. So what else do I need to check, and is this a problem I can fix myself, or do I need to call a service and repair company to repair it? Please help!! Thanks!! (more…)
Energy Star Gas Furnaces | We get this question from time to time about Energy Star gas furnaces and how it can benefit you as a consumer. Therefore we are going to fill you in on the specifics of Energy Star and include information about gas furnaces with the Energy Star logo. So the posed question is, “What is an Energy Star rated gas furnace”? And, “How can it benefit me”?
First, let’s look into Energy Star and what it is. Two specific government agencies manage Energy Star. The Department of Energy and the Environmental Protection Agency. A manufacturer producing products that use energy to work must pass certain guidelines approved by these agencies to use the Energy Star logo. That includes signing an agreement and using third-party testing to test the efficiency of the product. If it passes certain efficiency tests, then the manufacturer may use the Energy Star label on their product. This includes gas furnaces. (more…)
Lighting a Pilot that is Electronic Ignition - This is one of many questions we get by email.
Lighting a Pilot that is Electronic Ignition Comment: Thank you for your interesting discussion of pilot lights vs. electronic ignition. I may have to replace my gas water heater soon and am weighing the options. Although I understand that electronic ignition is more efficient, I worry about not having hot water during a power outage.
Several years ago, we had an ice storm, and the power was out for almost a week. My gas water heater still worked as did my gas stove, and that made a big difference. That happened when the temperature outside was in the ’20s (F). Is there any way to light a water heater with electronic ignition by hand? Or is it completely dependent on electricity? Thanks for any information you can provide. (more…)
HVAC Tip - You can add energy savings by placing a blanket wrap insulation around your water heaters. Additionally, for electric water heaters, you can have a timer added to the power circuit to turn the water heater off in times when there is no usage. For example: Set the timer to turn the water heater off from 10 p.m. to 4 a.m. Most timers can be customized and set for different times so that the water heater is turned off for most of the day and night. This, along with the insulation (which will keep the water hotter longer), can save in energy usage and your energy costs.
