Furnace Off During the Summer
With summer and hot temperatures here, the last thing you probably have on your mind is whether or not you should have your furnace on. In fact, you probably turned it off months ago. However, it’s now time to question whether or not that was the right choice. It could have an impact on your HVAC system.

Is Your Furnace Really Off?

The first thing you need to consider is what it means to have your furnace “off.” You may think that when you switch it from “heat” to “cool” that your furnace has been turned off. In reality, this is not the case. This switch does stop the furnace from running, but your heater and air conditioner are tied into the same HVAC system and use the same ducts and registers to move air. To truly turn your furnace off, you would have to extinguish the pilot light. This would ensure that no hot air circulates through your home during the summer months. Whether or not this is a good idea depends on where you live.

When Does Turning Off the Furnace Make Sense?

Even though warm air is not being circulated through your home, it still costs to have the pilot light burning. It may not be much, maybe around $50 a month, but this could add up over time, and it varies based on the market price of natural gas. In addition, turning off the pilot light could save energy since it won’t be wasting gas to keep it burning. Thus, if you’re looking for a way to save some money and to be more energy efficient, it might be useful to turn off the pilot light. Keep in mind that if you do this step, if you need to relight it, you may have to call in a HVAC professional to help you with this task.

Turning Off Your Furnace

If you want to turn off your furnace, you’ll need to turn off the main gas supply. Ensure that it is only the gas supply to the furnace and not the entire house. Otherwise, you won’t have any hot water over the summer. That’s it! It’s an easy step to take, and one that could have a lot of savings. Knowing if you should turn off the pilot light will depend on the weather. If you’re confident that there won’t be any cool days during the summer, then completing this task is beneficial.
