Furnace repair and replacement in Chicago Heights
When a furnace fails in the middle of a Chicago winter, you need a licensed crew you can reach. Mountain Top repairs and installs furnaces in Chicago Heights and across the South Suburbs.
Most furnace calls come down to a short list of causes: a worn ignitor, a dirty flame sensor, a failing blower motor, a thermostat problem or a clogged filter. A technician can usually tell you which one you are dealing with after a proper look, and that is where we start.
Why customers choose us for furnace work
We diagnose first and sell second. If a part and a cleaning will get you through the winter, that is what we will recommend. If the furnace is old enough that repairs are only postponing the bill, we will say so and explain what a replacement involves. Either way, you get the full picture before any work begins. When a new furnace is the right call, our licensed technicians handle the installation from start to finish.

Things worth thinking about
Do not wait for a total shutdown
A furnace that short cycles, rattles or takes longer to warm the house is giving you a warning. Fixing it early usually costs less than fixing it in an emergency.
Know roughly how old it is
Age is a big part of the repair-or-replace decision. The model and serial number are on a label inside the cabinet.
If you smell gas, get out first
Leave the house, call your gas utility from outside and then call us. Do not flip switches or try to find the leak yourself.
Four steps from first call to finished job
Every job follows the same four steps, whether it is a furnace repair or a new boiler.

Heating FAQ
Serving Chicago Heights and the South Suburbs. Not seeing your question? Call or text 708-407-6296.
Should I repair or replace my furnace?
It depends on three things: how old the furnace is, what the repair costs and how often it has been breaking down. We look at all three and give you a straight recommendation, including when repair is the better choice.
Do you offer emergency furnace repair in Chicago Heights?
Yes. We offer a 1-hour emergency response, 24/7. Call or text 708-407-6296 and tell us what the furnace is doing.
Do you install new furnaces?
Yes. Our licensed technicians install new furnaces in homes and commercial properties across the South Suburbs.
Why is my furnace not turning on?
Start with the simple checks: the thermostat is set to heat and has power, the breaker has not tripped, and the filter is not badly clogged. If those are fine, the cause is often a worn ignitor, a dirty flame sensor or a failed blower motor. If it still will not start, call or text 708-407-6296 and tell us what the furnace is doing.
What if my furnace is running but the house is not getting warm?
A dirty filter, a failing blower or an ignition problem can all leave a furnace running without producing enough heat. It is worth having a technician take a look before it fails completely. Call or text 708-407-6296 and describe what you are noticing.
