Signs You Need A New Gas Furnace
Higher bills. If you’ve noticed increases in the amount of gas your home uses, your current furnace may be losing its efficiency. A professional from Alliance Heating and Cooling can investigate to see what’s causing that.
Frequent breakdowns. It’s not unusual for gas furnace to need an adjustment or minor repairs from time to time, but if you’re calling for help more often than you’d like, you may save time and money by upgrading to a more reliable until.
Different temperatures. A well-running furnace can spread heat evenly through your home, so if you’ve started to notice big temperature differences between rooms, it may not be working as well.
Off and on. It’s normal for gas furnaces to cycle off and on over time as they keep your home at a comfortable temperature. If they’re cycling every couple of minutes, something probably isn’t right.
Strange noises. Most homeowners get accustomed to the sounds their gas furnace makes when it’s operating, but if you’ve started to notice new or worrisome noises, we should probably check them out.
It’s getting older. Even the most reliable gas furnaces are designed to provide about 15 years of service. If yours is past that age, replacement may prove to be a smart idea.
What Makes Gas Furnaces An Affordable Choice For Our Area?
When you select a heating system for your home, you’re primarily focused on two things: comfort and cost. In our part of the Northeast, gas furnaces deliver both. That’s especially true when it comes to today’s most efficient gas furnace models. They’re designed to extract as much heat as possible from natural gas. With advanced burner systems, super-efficient heat exchangers, and variable-speed blower models, they keep your home comfortable while using far less gas. That means you can expect to see lower utility bills without sacrificing any of your family’s comfort.
The Alliance Heating and Cooling team can help you see just how affordable upgrading to one of today’s high-efficiency gas furnaces can be. By comparing a new furnace to your existing system and using your actual bills, they can help you predict the savings you’ll enjoy from an upgrade. In addition, we offer a variety of helpful financing programs that make it easier to improve your home’s comfort – along with information about incentives that are available in your Connecticut or New York community.

Repair costs depend on the issue, but Alliance HVAC always provides upfront estimates before work begins. Minor repairs are often affordable, while larger component failures may require replacement parts.
