A Cracked Heat Exchanger in a Furnace Is a Serious Repair Issue

Monday, March 2nd, 2020

We want people to know that gas furnaces are not dangerous to have in their homes. If gas furnaces presented high safety risks, they would never be allowed in houses in the first place. But natural gas furnaces can potentially create health hazards if they’re neglected and don’t receive repair work promptly.

In this post, we’re going to look at a gas furnace malfunction that can turn dangerous for a household. It’s a cracked heat exchanger, and it can lead to the leak of carbon monoxide into the living spaces of a house.

How Long Can You Expect Your Furnace to Last?

Monday, January 20th, 2020

basement-furnace-openA furnace is not designed to run forever—no mechanical device can do that. But modern furnaces are built to last for many years before they start to malfunction on a regular basis, cost too much to run, or simply breakdown so completely that the labor involved in getting it working again would be prohibitively expensive.

What you want to know is… how long before your furnaces reached one of these points?

The answer is, as with so many other home comfort decisions, “it depends.” We can make a few generalizations about furnace age as well as signs of a steep decline that will tell you when a furnace is near to the end.

Dual Fuel Systems vs. Other Heating Options

Monday, December 23rd, 2019

fireplace-coupleA dual fuel system is designed as a halfway point between using the power of a furnace and the energy efficiency of an electrical heat pump. Natural gas furnaces are one of the best ways to provide warmth to a house because of their high heat levels and the availability of natural gas. Heat pumps can help save money using electrical heat, plus they also work as air conditioners.

But because of the cost of using natural gas and the trouble that heat pumps can encounter with extremely low temperatures, the dual fuel system became popular—a heat pump that uses a backup natural gas furnace to help when temperatures drop below 40°F. It does sound like the best of both worlds.

So why aren’t dual fuel systems in every home?

How a High Efficiency Furnace Gets Such Great “Mileage”

Monday, October 28th, 2019

green-houseEfficiency is one of the big words in today’s consumer products. People are always looking for appliances and vehicles and other devices with improved energy efficiency. Government labels like ENERGY STAR make it easier than ever for customers to find appliances that meet the standards for efficient operation.

Because a large amount of the energy consumed in your house during the winter goes to your gas furnace, finding one with a high efficiency rating can mean a significant difference in your utility bills. Older furnaces have AFUE ratings between 60% and 80% (meaning they lose about 20% to 40% of their fuel source to exhaust). New special efficiency furnaces have AFUE ratings of more than 90%. These high-efficiency furnaces cost more than mid-efficiency models, but they often pay for themselves in a few years.

Low Humidity and a Furnace: Is This a Thing?

Monday, October 14th, 2019

inside-gas-furnaceYou may have heard that a natural gas furnace, although one of the most powerful and reliable ways to provide heat to a home, has a major drawback—it dries out the air in a house. Since dry air during cold weather makes low temperatures feel worse, this can be a big issue. At least it is if there’s any truth to it. So … is there?

The answer is “yes and no.” A gas furnace can lead to a drop in humidity levels in a house, but the furnace doesn’t “dry out” the air itself. And not all gas furnace types have this effect. We’ll let our Cherry Hill, NJ, HVAC experts explain further.

Don’t Let Gas Furnace Repairs Go at the End of the Season

Monday, April 2nd, 2018

hands-opening-heating-cabinetApril may bring showers, but it’s also a time when the annual climate starts the ascent toward staying warm through the summer. Good news in most ways—but unfortunately one way it isn’t good is that it makes it more likely for homeowners to ignore a malfunctioning gas furnace. When people know they soon won’t need the furnace running for a long stretch, they might shrug off what looks like small malfunctions. Those can wait until the fall, can’t they?

We don’t recommend anyone take this approach! It’s always best to have gas furnace repairs done as soon as possible after you notice something is wrong. Arrange for a heating contractor to come to your house, inspect the system, diagnose the problem, and have it remedied.
