When our 22+ year old heat pump showed signs of failure, I did research. Consumer Reports named TRANE as the top pick for reliability and consumer satisfaction. Rick Boren, owner of Den-Son, Inc. is an authorized TRANE dealer. This means Den-Son, Inc. service technicians have the required training and experience to install and repair TRANE products. My mother and father-in-law have had a great experience with this company. My wife and I decided to give him a call. We bought a new heat pump, air handler and electronic air cleaner. Professional installation is more important than the best HVAC equipment. Den-Son's four installers arrived on time with the correct parts and tools and immediately began work. Each worker knew where to go and what to do. Together, they acted as a well-oiled machine! The four workers cooperated with each other - it was obvious they were either friends or family. All parts of our system were installed carefully and tested. Nate (owner's son) programmed our thermostat and explained how to operate and maintain our new air cleaner and other parts of the system. How does it work? The new TRANE HVAC system is extremely quiet. The compressor has 760 different speeds and the air handler also has numerous speeds. The thermostat decides which speed is most economical. We can feel cold air exiting the registers during summer but standing next to the air handler in the basement is slightly louder than a fan in a computer's power supply. Upstairs - silence. There are no drafts or wild temperature swings associated with older forced air furnace/air conditioners. My wife exclaimed, "The air seems crisper and slightly frosty. I'm sitting next to the floor register - my elbow is feeling cold but there is no (furnace) noise." The temperature throughout our house is very even and comfortable. Economy: Time will tell! Consumer Reports gave this system top ratings. I plan to compare Ameren Electrics daily usage data with previous year's to make a judgment. I purchased TRANE's best system with an electronic air cleaner. I consider a new HVAC system as a long-term investment. In the long-run, it pays to buy the best technology available. Energy costs are bound to increase dramatically due to inflation. We appreciate Rick Boren's consideration in checking back with us to see if we have any questions or concerns. I feel Rick is truly committed to providing service after the sale and providing support should we have issues. He has an excellent track record with my in-laws. The system has a 5 year parts/labor and a 10 year parts warranty through TRANE. Den-Son, Inc. is located in Brighton, IL near Godfrey and has been a family business since 1972. Yes, we're happy! We hope others reading this review will consider calling Rick if you need service, repairs or installations. Rick and his workers treated us right! read more
