"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!"

"They showed up on time and were very professional. Before they started, they reviewed what they were going to do and how much it would cost. My research on duct cleaning companies told me that this is where most duct cleaning jobs go south with extra charges. I was glad to hear that their cost estimate matched exactly what Hi-Tech told me over the phone and might even be less if they found ways to simplify the job. They got to work quickly, were neat and efficient and worked hard for 6 1/2 hours. When they were done I was amazed at all the "stuff" they pulled out of my ducts, including several dead mice! They did everything they said they were going to do exactly the way the video on Hi-Tech's web site said they were going to do it. They were neat and cleaned up all the areas where they worked. I was very satisfied with their work and the final cost came in $58 (8%) lower than their estimate and would strongly recommend Hi Tech Duct Cleaning over the companies who "also" do duct cleaning. There is no comparison!!"

"Ricky is an excellent technician. This is a new house for me and not familiar with some of the equipment. He completed our checkup and told me it was in good condition, familarized me with the system and some of the plumbing. That is part of the reason I signed for your plan. I was impressed with Ricky and his representation of your company. I would like for him to do my air conditioner in the Spring. Thank you."

"They are really pleasant, conscientious, and go the mile and more. Additional problems that showed up were taken care of as part of the install. All working smoothly so far. Just think their paperwork could be smoother and clearer."

"Jim with North Alabama Technical Services removed some items from my computer so that I could send emails and attend to items I needed to address that day. As planned, the next day he thoroughly cleaned my computer, he also made helpful suggestions while working on my computer. I would call him again if needed and I thought the fee was reasonable."

"I feel that I must mention how impressed I was with the service that Eagle Energy Geothermal, LLC provided. Within SECONDS of pressing the submit button on the website, I recieved a call from the company. Withinn an hour, they were at my grandmother's house taking care of things. She lives alone, and her A/C was not working in 90 degree heat! She happens to have a very old unit, but they were still able to fix it... I feel they went well above and beyond the call of duty!"
