The Coleman Echelon 97.5% High-Efficiency Furnace is unlike anything you may have owned before. It's an unusual experience, and you will first want to understand the three major types of furnaces.
If you're accustomed to the huge blast of heat followed by the long period of interior cooling that you find in traditional one-stage furnaces, this is completely different. Also, it is interesting to note that this Coleman furnace is made by Johnson Controls, which also makes York and other furnace brands.
Volume of Air, Level of Heat
Is it impossible to objectively judge a furnace, considering that the previous furnace was over a half-century old? Certainly, anything will be better than the previous furnace, right?
That's what I thought at first. And when it comes to volume of air output, that is especially the case. The previous furnace barely put out a trickle of air. After the Coleman furnace was installed, the blast of air blew out clouds of dust from the ducts.
It didn't help that the HVAC company had removed the air filter. Sofas, walls, windows, and everything horizontal was blackened. Though the dust problem is an issue with the HVAC company, not the Coleman furnace, it is a testament to the volume of air the Coleman put out to expel that dust.
Noise? This Coleman furnace is loud. Remarkably, it is as loud or even louder than the previous 50 year old furnace. And it's not due to the increased volume of air whistling through the vents.
The furnace unit itself is loud. Luckily, because the unit modulates, you only occasionally have to listen to the unit blowing a full capacity.
How Well Does It Modulate?
The reason to buy a modulating furnace is if you hate that long, cold period that precedes the single stage furnace kicking back on.
It's also tied to very green and eco-friendly results. If you like a warmer house, you likely tend to set a single stage or even dual stage furnace quite high to compensate for those cold periods. Thus, you're running a very hot furnace that turns on constantly.
But with the modulating furnace, you can set it right at the desired temperature of 72 degrees and find it to be quite comfortable.
The biggest task that this modulating furnace takes on is first thing in the morning, when it is called upon to heat up a very cold house. Instead of blasting away at full force right away, this Coleman furnace gradually increases its heat over a period of about fifteen minutes. It's a nice way to wake up.
Cost of Furnace and Installation
Even if you purchase the same Coleman furnace, your cost will vary, since factors are different: regions, dealers, installation, and your ability or willingness to negotiate.
This Coleman furnace cost $5,042.03. This price includes taxes but does not include any federal tax credits or local energy company rebates.
The local energy company rebate for this Coleman furnace was $250. Federal tax credits on this model are $1,500.
Keeping You Updated
Because furnaces are super long-term purchases--even more so than buying a car--I want to let you know how well this furnace works over the years.
Everything above was written soon after the furnace was installed. Below are the updates, winter after winter. I'm not overly bothered by call-ins for minor repairs, because normally you would want to have a technician come once a year, in late summer or early fall, to service the beast.
1 Winter After Installation: Works Fine, No Call-Ins
Now that I have run this Coleman furnace for one full season, I have a truer feeling about its operation. This furnace pushes out some major heat. Even in a poorly insulated house, this furnace kept the home toasty warm throughout the winter. But I'll add that I don't live in severe winter conditions. Most of the time, I was irritably walking to the thermostat and turning it down because I was too hot. This is all variable based upon the house structure and outside environment of the house.
3 Winters After Installation: Gas Valve Stuck and Condensation Collection Box Cracked
The rating was knocked down two stars after undergoing two repairs that cost $385. First, the pilot would light, but the burner would not go on because the gas valve was stuck. This was the first cycle of the season, so it could be halfway expected that things wouldn't be running as smoothly as possible. The technician banged the valve to get it open so that it would expel heat while waiting for a new valve to come in. Second and worst: the condensation collection box was cracked beyond help. The technician said that Coleman found out that this type of plastic wasn't good and that they changed to a softer, less brittle black plastic. The furnace was still under warranty, so the parts were covered.
4 Winters After Installation: Blow Out Tube
It's now an annual ritual to call in the heating man. This time, the furnace would attempt to turn on--and it would sound promising for a few minutes--then would shut down before warm air could come out of the vents. The furnace guy charged for the minimum show-up fee because the only problem was a little clear plastic tube that needs to occasionally be cleared out. Debris or calcification or something of that nature will clog the little tube.
5 Winters After Installation: Running Smoothly
This is the first winter where the Coleman kept on running with no need for repairs.
