We all know what it’s like when an arctic blast rolls across the Great Lakes. The temperature plummets, the wind howls, and the lake effect snow falls furiously. Depend on Merts Heating & Air Conditioning to keep your Lake County, IN home comfortable inside, no matter what’s happening outside. Featuring efficient furnaces by Bryant, Merts has been delivering “Quality and Honesty Since 1952.”

Home heating choices

Forced air furnaces have become the mainstay of home heating. Radiant systems have some advantages, but it’s hard to beat the low upfront cost of the traditional furnace. Most burn natural gas—which are generally the cheapest fuels.


This is an important part of deciding which system is best for you. Furnace efficiency is measured by the AFUE (annual fuel utilization efficiency) rating. If a furnace has an AFUE of 75 it means 75% of the heat produced goes to heating the home and 25% is considered to be wasted. Not too many years ago furnaces with an AFUE of 50 to 70 were common. Today, an AFUE rating of 80 is considered a minimum and high-end models can be as much as 98% efficient. It doesn’t take a degree in math to know replacing your old furnace can save you a bunch of money on your monthly bills.

So, what’s the right number?

Higher efficiency furnaces almost always cost more but will save more money in the long run. Merts will show you several options so you can crunch the numbers yourself. Then it’s up to you to decide which heating option fits your needs and budget.
