"We got several quotes from local HVAC providers / installers. We felt the most comfortable with the salesman from Extreme One Hour Heating and Air Conditioning and I got the best price from them which also included a 2-year membership in their Comfort Club (Spring and Fall service visits to check and tune-up my system). We were an all electric home until a couple of years ago when we added natural gas. When our 16-year old Trane heat pump developed problems this proved an ideal time to switch over to a gas furnace and air conditioner. We stayed with Trane as we were happy with our Trane heat pump. Because we have some space constraints and limitations for our new system, Extreme sent out their system designer the day before the installation to develop a creative solution that met our requirements and efficiently maximized the space with which they had to work with minimum impacts to us. The day of the install they arrived on time, were friendly but very professional and treated our home as if it was their own. They also took the time to answer my questions while the worked. Since it was bitter cold that day, they needed to be in and out all day, and we were without a heating system most of the day, they brought a heavy duty space heater to keep us from freezing until they were done. At completion, showed us how to use the new system including the new programmable thermostat, changing filters, etc. and they cleaned up everything and left our home better than they found it. They then submitted all of our rebate paperwork to Vectren and DP&L for us. We were very impressed with the whole process of buying and installing a complete new HVAC system. I highly recommend Extreme One Hour Heating and Air Conditioning for and HVAC installation work!"

"This company is very good. My water heater was beginning to leak and I knew it was time for a replacement and upgrade. Ecoplumbers was able to schedule the day after my initial contact. Ryan offered a quote, explained what he planned to do and installed a new heater within 3 hours. Communication between scheduling services, the service technician (Ryan) and myself was excellent. I am very happy that I used this company"

"First of all I am not easy to satisfy. I run a local roofing and restoration company so I expect a lot. I analyze not only quality but price and customer service as well. Wells HVAC satisfied and even exceeded my expectations. I thought I had a good offer from another provider and I explained to wells that I was ready to pull the trigger with another deal but they came out and offered a better deal with a better warranty at a better price than the one I was going to go with. I was really happy they replaced the system in my Condo. I plan on using them to replace my unit in my other condo when it goes out and possibly the unit in my primary home. You can end your search here and go with Wells. You will be glad you did!

"Spending money on airduct cleaning might be one of my least favorite ways to spend money. One of those must do things for a home that is never fun. But Scott and his team made it as painless as possible. Scott was ON TIME, did a great job, explained everything, and was really professional. He gave me some advice on my airducts and even fixed a few bad areas another contractor botched. He also somehow got my dog who is afraid of men to let him pet her. Hire him!!"
