Furnace Maintenance

In the often cold winters of the Chicagoland area, having issues with your furnace is the last thing anyone wants. At, we believe that the best response to those issues is to prevent them from coming up in the first place, which is why our dealers offer comprehensive home furnace maintenance services. Regardless of your make and model of furnace, our maintenance experts have the tools and the technical knowledge needed to keep your essential home heating equipment running without issues for many years to come.

Today's budget-conscious world means that many homeowners are looking for ways to reduce their monthly expenses, cutting costs wherever they can. To this way of thinking, routine maintenance often looks like an unnecessary expense, but nothing could be further from the truth. In reality, not having your furnace maintained is an unnecessary expense. With proper annual furnace maintenance, your system will heat your home more efficiently, saving money monthly on fuel costs. Furthermore, maintenance reduces the risk of future issues and the potentially expensive repairs that could come with those issues.

The Maintenance Process

During each maintenance visit, our technicians perform the following checks:

  • Heat exchanger inspection for cracks and deterioration.
  • Burner inspection and cleaning.
  • Fan switch check and adjustment.
  • Pilot and pilot assembly check.
  • Safety control inspection.
  • Combustion air opening check.
  • Flue pipe inspection.
  • Temperature and performance check.
  • Panel check.
  • Control and safety inspection and test.
  • Lubrication of motors and bearings.
  • Belt and pulley adjustment.
  • Air filter inspection and replacement.
  • Electrical check.
  • Thermostat calibration.

These procedures not only include preventative care but also the small calibration adjustments needed to keep the furnace running at peak efficiency. Thus, oil or gas furnace maintenance saves you money right away on annual fuel costs and down the road on potential repairs.

Our Qualifications

The dealers on this site hold Carrier or Bryant factory authorization, which places them among the top HVAC contractors in the area.
