Frequently Asked Questions
How often should I have my furnace tuned up in Lemont?
Most heating professionals recommend scheduling a furnace tune-up once a year, ideally in the fall before the heating season begins. Given how hard Illinois winters can push a heating system, annual maintenance is a practical way to stay ahead of potential problems. You can schedule a tune-up with McNally’s anytime that works for your schedule.
What are signs that my furnace needs repair?
Common signs include uneven heating throughout the home, unusual noises like banging or rattling, a furnace that short-cycles on and off, a yellow or flickering burner flame, or a noticeable increase in energy bills without a clear explanation. If you are noticing any of these in your Lemont home, it is worth having a technician take a look. Learn more about what our heating services cover.
How do I know if I should repair or replace my furnace?
A good rule of thumb is to consider replacement when repair costs approach or exceed half the cost of a new system, especially if the furnace is more than 15 years old. Older systems also tend to run less efficiently, meaning higher utility costs over time. Our technicians can walk you through an honest assessment and help you weigh the options for your Lemont home.
Does McNally's serve commercial properties in the Lemont area?
Yes, McNally’s provides heating service, furnace repair, and installation for both residential homeowners and commercial businesses throughout Lemont and surrounding communities like Romeoville, Bolingbrook, and Darien. Whether you manage a small office or a larger commercial facility, our team is equipped to help.
What is a heat exchanger inspection and why does it matter?
The heat exchanger is the component that separates combustion gases from the air circulating through your home. A cracked or failing heat exchanger can allow harmful gases to enter your living space, which makes inspection an important part of any furnace service visit. Our technicians include a thorough heat exchanger evaluation as part of our standard heating tune-up process.
