We had AirTech come out 2 look at our home to see if what we wanted to do was even possible. Daniel was our sales guy. He explained that it was completely possible, duct work would need to be replaced and re-routed in our attic. He also explained that technology has advanced so drastically over the past decade in HVAC, that we have several options for what we could do. He was in our home about an hour, took a lot of notes, some measurements, and told me he would get back to me in a few days with the estimates. We had figured somewhere near $20,000 for the project and when the estimates came in higher, we didn't flinch at them. We looked at the equipment they were quoting, knew it was good equipment, had trust in AirTech, knew they had hundreds of excellent reviews online, and decided to go ahead with the process. We called them up and asked when they could start. They scheduled us for the next day. That very afternoon (day before the install), Billy Wagner, President of AirTech, came to our home, walked the property with us, made sure we had all the clearances necessary for the equipment, made sure we understood what was going to be done, confirmed our wishes, made sure the salesman quoted the appropriate equipment for our home, and really took the time to make sure all of our questions were answered. Billy decided that we could benefit from 2 different units than what the salesman had quoted, explained the benefits, we asked him for a new estimate, when he gave it to use, it was almost $2000 less than the original. WOW, a company that could've made another $2,000 and didn't because they had the best interest of the customer in mind. HAVE I SAID YOU SHOULD HIRE THEM YET??? YOU SHOULD HIRE THEM!!! Day of installation. Everything from start to finish was so smooth. They arrived on time (actually 5 minutes early), called me when they were on their way (as they had said they would, but how many times have we heard, "We'll call when we're on our way" and then never get a call). They arrived, began unloading equipment, removing old equipment, and removing old duct work in the attic. They were at my home from about 9am until 8pm. I couldn't believe they stayed to finish, what a long day, I figured 5pm was gonna roll around and they were gonna come back the next morning. NOPE, they promised it would be done in one day and they kept that promise. Before leaving they setup all the new digital thermostats (very technological system), showed me how to program them, change settings, connect my wifi, use the mobile app, connect the system to my Amazon Echo, and made sure all of my questions were answered before leaving. The next few days were quite warm outside and the air would kick on here an there, WOW, we immediately noticed a huge difference. The system starts up slow, gradually increases to the speed it needs based on the algorithms in the system, and cools the house so much faster. Here's the cool part, after it's done, it shuts off the compressor outside but leaves the fan on in the attic for a few more seconds to clear all the cold air from the ducts. AWESOME, no more wasted cold air. They had mentioned that they may need to come back and do some adjustments on airflow since we went with zoning off the upstairs into 3 zones. We had a cold front come in, 3 days in the low 50s and lots of rain, nights were in the low 40s. When the heat would come on it sounded like we were in a wind tunnel and didn't seem to be adjusting itself down. About this time, we received our final invoice and warranty registrations from AirTech. I decided to do some research on the furnace's multiple speed capabilities. I looked on the manufacturer's website found my model number and starting researching the variable speed. This is where we ran into a problem. Not because of AirTech, but because of the manufacturer, American Standard. As I was researching I decided to look at the compressor unit information for the a/c as well. We were quoted and told by AirTech that they installed a 3 ton unit for our 2nd floor. According to the manufacturer website, the model number that was on our warranty paperwork was a 2 ton unit. I of course immediately called AirTech, very upset, and explained the problem. Billy, explained to me that it was in fact a 3 ton system. I was dead set on believing the manufacturer and not AirTech. Billy told me he would get the 3rd party certification documents for the unit and bring them to me when they came to adjust the airflow the following morning. I called the manufacturer and asked them to verify what the ton rating was on the model number. The representative explained it was a 3 ton unit. I pointed out that their website says it a 2 ton unit. Once they explained the way their model numbers break down to show how much tonnage, I pointed out that several of the units on their website are listed wrong. He agreed, and sent me all the necessary documentation to ease my mind. The following morning, when Billy arrived, the first thing he did was go through the 3rd party certification with me. This also showed it was a 3 ton unit. AirTech has gone above and beyond to make sure that I am satisfied as a customer and to build a customer relationship with me. They didn't just come in, throw my system together and then just disappear. They have been very responsive, very punctual and very professional, even when I was angry, they maintained and conducted themselves very well. I CANNOT EXPRESS ENOUGH HOW MUCH I TRUST AIRTECH. I CANNOT EXPRESS HOW THEY HAVE EARNED A LIFE LONG CUSTOMER. THEY TRULY CARE ABOUT THEIR CUSTOMERS AND SHOW IT IN EVERYTHING THAT THEY DO. THE QUALITY AND PROFESSIONALISM IS UNSURPASSABLE. THANK YOU AIRTECH. TOM THOMPSON
