Why Des Plaines Homeowners Choose McNally's
Situated just northwest of Chicago, Des Plaines sits in a region where homes face serious heating demands for a good portion of the year. Many of the homes near landmarks like the Des Plaines River Trail corridor have been around for decades, and older heating equipment requires experienced hands and careful attention. McNally’s technicians bring both to every appointment.
We are a locally rooted company, and that means we are familiar with the specific needs of Cook County homeowners, from the older construction found throughout Des Plaines neighborhoods to the commercial properties along Mannheim Road. Our approach is built on transparency, quality workmanship, and treating every customer the way we would want to be treated ourselves.

Frequently Asked Questions
How often should I have my furnace serviced in Des Plaines?
We recommend scheduling a furnace tune-up once a year, ideally in the early fall before the cold weather arrives. Des Plaines winters can be harsh, and getting your system inspected before you actually need it running full time helps catch small issues before they become larger ones. Schedule your tune-up here.
What is a heat exchanger inspection and why does it matter?
The heat exchanger is a critical component of your furnace that separates combustion gases from the air that circulates through your home. A cracked heat exchanger can allow harmful gases to enter your living space, which is why inspecting it is a standard part of our annual furnace tune-up. Our technicians check this carefully on every heating service visit.
My furnace is older but still running. Should I repair it or replace it?
This is one of the most common questions we hear from Des Plaines homeowners, especially those in homes with original heating systems. The answer depends on the age of the equipment, the cost of the repair needed, and how efficiently the system is currently operating. Our technicians will give you an honest assessment so you can weigh your options. You can also check out available promotions if a new installation makes sense for your situation.
