Merts also serves the furnace and home-heating needs of Will County, IL residents, including the county seat of Joliet. Outsiders may not realize Joliet is the fourth largest city in the state. Home to two casinos, Chicagoland Speedway, and the10-acre Billie Limacher Bicentennial Park & Theatre, Joliet is the self-proclaimed City of Excitement.

FORCED AIR FURNACES

Like just about every other location in the country, these are the mainstay of home heating for Will County homeowners. Most forced air furnaces burn natural gas. Advantages include relatively low upfront costs compared to more exotic forms of heating and natural gas is generally the cheapest fuel.

EFFICIENCY

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 energy produced by burning the fuel goes to heating the home. The other 25% is wasted, usually exhausted through the flue. 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. 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?

Energy efficiency is great, but it comes at a cost. High-efficiency furnaces are more expensive upfront. During the sales process our staff will show you the numbers so you can see how much money you can save each month. After you see the numbers it’s up to you to decide if the efficiency is worth the investment.
