Frequently Asked Questions
How often should I have my furnace serviced in Westmont?
Most heating professionals recommend scheduling a furnace tune-up once per year, ideally in early fall before the cold arrives. Given how demanding DuPage County winters can be, staying ahead of maintenance helps your system run efficiently and reduces the chance of an unexpected breakdown mid-season. Learn more about what a tune-up includes on our heating services page.
What are the signs that my furnace needs repair?
Common signs include uneven heating throughout your home, unusual sounds like banging or rattling, a furnace that cycles on and off too frequently, a noticeable increase in your energy bills, or a yellow or flickering burner flame instead of a steady blue one. If you notice any of these in your Westmont home, it is worth having a technician take a look. You can schedule a diagnostic visit here.
Does McNally's handle furnace installation for businesses in Westmont, not just homes?
Yes, we work with both residential homeowners and commercial businesses throughout Westmont and nearby communities like Clarendon Hills and Darien. Commercial heating needs can differ from residential ones, and our team has the experience to handle a range of building types and system configurations. Reach out or schedule a consultation online to talk through your specific needs.
What does a heat exchanger inspection involve and why does it matter?
A heat exchanger inspection involves a careful visual and sometimes combustion-analysis check of the component that separates combustion gases from the air circulated through your home. A cracked heat exchanger is something that should be addressed promptly, and it is one of the key items we examine during every tune-up and service visit. It is one more reason regular maintenance is worth scheduling each year.
Is there anything I can do between service visits to keep my furnace running well?
Replacing your furnace filter regularly, typically every one to three months depending on your filter type and household, is one of the most effective things you can do between professional visits. Keeping vents and registers clear of furniture or obstructions also helps your system distribute heat efficiently. For everything else, our team at McNally’s is here when you need us. You can also check our promotions page for seasonal service offers.
