Replacing your furnace blog

If the heating and air conditioning system in your home is over 8-years old, it’s probably time to think about a replacement.  While you’ve properly maintained your HVAC system and it may appear to be performing, it’s likely costing you. 

Today’s heating and air conditioning systems are incredibly sophisticated machines – far superior to their predecessors.  They’re fine-tuned, highly-sensitive operating systems designed with controls and sensors to maximize efficiency.  Efficiency that keeps more treated air inside your home (less up your chimney) and requires less energy (and lowers utility bills).

Choosing the ‘right’ system can be complicated.  This blog will highlight issues and processes for any homeowner to use, in securing the best solution for your family’s comfort.

Size Matters

The technicians at Flader Heating and Air Conditioning are experts at calculating your heating needs based upon industry standards – as defined by the Heating Contractors of America.  These standards weigh key variables such as our mid-west climate, the square footage, design, and construction of your home, and closeness to Lake Michigan. 

A furnace that is too large will cost more and wear down due to cycling on-and-off too frequently; a furnace that is too small will not keep you comfortable during our Midwest winters and summers. 

With over 100-years of experience in our community, Flader Heating and Air Conditioning knows which systems and brands work best for homes in your neighborhood. 

Efficiency Rating

Simply stated, this rating refers to the percentage of the heat generated by a furnace that is actually used to warm your home.   Many old furnaces have ratings in the 70s – meaning only 70% of the heat they generate actually stays in the home (30% going up your chimney).  Most of today’s high-efficiency furnaces are rated 90 or 95 – meaning that 90% or 95% of the heat they create is staying in the home. 


While high-efficiency furnaces are initially more expensive, they save homeowners in energy expenses each month.   Monthly savings on your energy bill often pay the difference over the life of your system.  Plus, it’s environmentally responsible.    The knowledgeable experts at Flader Heating will calculate the annual estimated operating cost of the models you’re considering.  You can weigh the savings.
