Common Furnace Problems
When you call a contractor to repair your furnace, there are certain problems professionals are used to seeing during their inspections.
Some of the more common problems can include:
- Poorly maintained unit: Failing to schedule regular annual maintenance and tune-ups on your unit can cause issues with your system.
- Dirty filters: Forgetting to change filters regularly can lead to an accumulation of dust, dirt and other debris that can cause poor air quality and even potentially cause your unit to malfunction.
- As a unit nears the end of its lifespan: It can show signs of wear and tear and require more frequent repairs.
- Malfunctioning thermostat: If the temperature in your home doesn’t match the temp set on the thermostat a professional will need to inspect it to determine the issue.
- Poor airflow: Disrupted airflow can be dangerous, as it can cause the unit to overheat.
- Carbon monoxide leak: One of the most serious issues with a furnace can be a carbon monoxide leak. This can put your family’s health and safety at risk. If you suspect you have a leak, or if you notice symptoms that can include excessive condensation on windows or a pilot light that turns from blue to yellow, evacuate the property and call a professional immediately.

Frequently Asked Questions
Q: How do I know if my furnace needs repair or replacement?
A: If your furnace is less than 10 years old and the issue is an isolated component like a thermostat or ignitor, repair is usually the right call. If your system is more than 15 years old, requires frequent repairs, or your energy bills have increased significantly, replacement is likely the more cost-effective long-term decision. A TR Miller technician will assess your system honestly and give you a clear recommendation before any work is done.
Q: What should I do if my furnace stops working in the middle of the night?
A: Call TR Miller at (815) 912-0028. Our team serves Bloomingdale homeowners and we will get a technician to you as quickly as possible. In the meantime, keep interior doors closed to retain heat in occupied rooms, and never use a gas range or portable propane heater as a substitute heat source — both are serious carbon monoxide hazards.
Q: How often should I have my Bloomingdale home furnace serviced?
A: Once per year, ideally before heating season begins in the fall. An annual tune-up keeps your system running efficiently, extends its lifespan, and allows a technician to catch developing problems before they cause a breakdown. TR Miller offers heating maintenance plans that include an annual tune-up so you never have to remember to schedule it.
Q: Does TR Miller service all furnace brands across Bloomingdale, IL?
Modern high-efficiency natural gas furnaces can reach up to 98% AFUE efficiency, making them the most cost-effective option for most Chicago-area homes given the region’s cold winters and existing gas infrastructure.
