A furnace is a 15 to 20 year decision, so we walk you through the options, from a dependable single-stage model to a quiet high-efficiency furnace, and give you a clear price in writing.

Frequently Asked Questions
How long does a furnace installation take?
Most replacements take one day. A new install with duct changes can take one to two days.
How do I know it is time to replace my furnace?
Look at age, repair history and bills. A furnace over 15 years old that needs repairs every year or keeps raising your gas bill is usually ready for replacement.
What size furnace does my home need?
That depends on your square footage, insulation, windows and ductwork, not on the size of the old furnace. We measure and calculate it during our visit.
Is a high-efficiency furnace worth it?
In a northern Indiana winter, usually yes. A 96% furnace costs more up front but uses less gas every month, and it may qualify for a NIPSCO rebate.
