The top questions our customers ask

Your guide to common furnace problems.

Still have a question? Call us 24/7.(708) 687-6898
What should I do when my furnace stops working?
Call us right away for 24/7 service. Without heat, your home isn't just uncomfortable, it's at greater risk for frozen pipes. We'll send a technician out as soon as possible.
Why isn't my furnace producing enough heat?
If it's running, it could be working overtime to warm your home. That can come from a mechanical issue or an undersized system. If you have spotty heat throughout your home, call us.
Why does my heating bill keep climbing every year?
Rising energy bills can be a sign of an inefficient or malfunctioning furnace, or an issue with the thermostat or ducts. We recommend an inspection.
Why is my furnace so loud or making strange sounds?
Constant starting and stopping is called short-cycling, and usually means there's a problem. Other noises, including loud operation, should be checked by a professional. Normal vs. unusual furnace noises.
Why does my furnace keep turning on and off?
Constant starting and stopping is called short-cycling, and it usually means there’s a problem. Have a professional check it before it causes more wear.
