The “life changing” furnace!

December 14, 2011

We often talk with customers about which furnace is the quietest, the most comfortable, and so on and so on. But, when you hear everyday how one particular furnace & experience is changing peoples lives & way of living; I find it best to share with everyone. Here is a testmonial I recieved from a customer in Indianapolis on the Lennox SLP98v furnace & Control Tech’s service.


Last month, Control Tech installed a new gas furnace in my home. During the course of the transaction, I was in contact with you, the office staff, service technicians and installers. I found all of you to be knowledgeable, professional, efficient and courteous. In particular, I appreciate the personal attention I received.

The Lennox SLP98v is so quiet, you can hardly hear it running and my sleep has improved because I’m no longer awakened by the sound of the furnace coming on and that first blast of cold air. Heating throughout the house is more uniform and the hot and cold “pockets” are gone.

I’m very pleased with the product and Control Tech and will be recommending both. It’s been a pleasure doing business with you and I thank you.

When I arrived to his home (before we began looking at options) he said “I’ve been on Lennox’s website, and I want the SLP98v.” I still gave three options as we always do; and he was still set on the SLP98v. I told him he wouldn’t regret this choice. Not only do we install quality equipment; we employ quality technicians to make sure all of the “fine tuning” is given special attention. He also stated, when we were talking at his home, that he loves how the temperature is even throughout the home. With his old furnace, he used to have to turn the thermostat up to keep the bedroom warm, but the rest of the home would be extremely hot. Now, with the variable speed blower motor, the temperature is consistant throughout.

‘Tis the season!

August 26, 2011

It’s that time of year again!… Or is it?… It’s time to start thinking about the winter and whether or not your furnace is going to make it through! I know it’s been one of the hottest summers we’ve had in a long time and most people are reading this going “are you kidding? Why would I be thinking about heat right now?”. The bottom line is; if we have as cold of a winter as they are predicting, everybody is going to be calling at the same time to get an estimate on replacing the furnace. Because, as most of you know, it never fails; your furnace will go down at the same time as everybody in Central Indiana.

Furnaces have really come a long way. They used to just be that “box inside”; but now they are so much more. What with variable speed blowers, multi-stage heating, extremely quiet operation, and so on. You’re getting much more than “box” that blow heat through your home. You are getting the “brain” of your home comfort system. The furnace controls the volume of air, heat, and dehumidification that is delivered to your home. Variable speed blowers are a no brainer when you are replacing your furnace. They are able to ramp up or ramp down depending on the temperature levels in the home. In the winter you can get “cold blasts” of air with your typical “single-speed” blowers; variable speed blower eliminate this because they are constantly circulating the air in the home and keeping a “more average” temperature. It’s kind of like cruise control for your system.

When you hear people talk about multi-stage, two-stage, and single-stage heating; they are referring to how many levels of heat the furnace has. The best way to explain this is; a single-stage furnace will put out 100% of its capacity 100% of the time. A two-stage furnace has a low setting and a high setting for heat. On mild days, a two-stage furnace runs at a lower capacity (1st stage) to take the chill off. When 1st stage can’t keep up; it goes in to 2nd stage. Multi-stage or “variable capacity” furnaces work much like the cruise control system of high-performance automobiles, automatically making adjustments as necessary to allow maximum fuel efficiency. They typically start at 35% of capacity and can ramp up or ramp down in 1% increments.

There are so many options out there. Make sure you contact the professionals at Control Tech when you are ready to make a decision. Keep in mind most estimates require 60 to 90 minutes to properly size a system for your home! We can’t make a 20 year decision in 15 minutes! When you call; please ask for me or mention this article!
