Considering Furnace Replacement? What You Need to Know Before You Shop

post img Before delving into furnace replacement, take some time to learn what types of furnaces are available and which receive the highest efficiency ratings. Installation is another critical factor in proper furnace functioning, and choosing the right contractor is as important as selecting the right furnace.


Reputable contractors determine the correct size furnace for your heating needs by determining load calculations for the home. This takes into account the climate, size, design and construction of your home using the Manual J HVAC Residential Load Calculation, which is distributed by the Air Conditioning Contractors of America. A furnace that’s too small won’t keep your house comfortable during the Cincinnati winters, while furnaces that are too large cost more and cycle on and off frequently. This wastes energy and causes temperature variability.


Most new furnaces use gas for fuel. The annual fuel utilization efficiency (AFUE) rating reflects how efficiently the furnace transforms gas into heating energy. Higher numbers translate into greater efficiency. Some furnace models attain 97 percent fuel efficiency. When you’re looking for a furnace replacement, furnace costs increase with higher fuel efficiency levels, but lower monthly fuel bills allow homeowners to recoup the additional expenditure.

Key Features

Furnaces have comparable key features, depending on price. Highly efficient furnaces often include all the key features, including:
  • Variable-speed blowers
  • Variable heat output
  • Air filtration
  • Dual heat exchanger
  • Zoned heating using thermostats
  • Warranty

Choosing a Contractor

Contractors are the determining factor in how well furnace replacement installation goes. Furnaces are attached to ductwork, piping and air cleaners, making them part of the entire home system. Only a trained and licensed HVAC professional should be considered for furnace installation.
