They cleaned the coil and vents, also rerouted the condensation drain that had been incorrectly installed.

I would highly recommend and we will definitely use them again.

It took Pat a couple of days to return my call - I expected it from busy contractor teams and…read moredidn't mind. I used the time to show the project to a few other contractors. Pat stopped by, and I was immediately taken by how passionate he was about the foam technology - a solution I was secretly leaning toward from my own studies. What he said resonated with what I read. Plus, I loved to work with people who are passionate about what they do. Verbal agreement reached. Pat had to delay the scheduled work a couple of times due to jobs at hand, and he had a even bigger job starting right after mine. I got concerned. By the time his team got to me, they had exactly one day to finish the job. I worried if the work quality might suffer. Pat and his team showed up on time in the morning. By the time I got home from work in the afternoon, they were done. I inspected the area, not only did they vacuum the old fiberglass as agreed, and foamed the whole vaulted ceiling, sealing every nook and cranny, they also fixed a major leak in my duct work, and foamed my AC return air plenums to keep from energy loss (duct work was not in the agreement). Ernest, one of the guys climbed under both of my fake gables to reach the real ceiling above them to foam it (I didn't even know about the hidden ceiling). All three of the guys had to have pushed hard to get so much done in one day - and then some. A big smile on Pat's face told me he was proud of what they did. It's been a couple of weeks now, and for the first time since I bought the house, I felt warm air coming out of the vent during 40 degree nights outside. The air was able to reach the 72-75 range I set, and actually stopped blowing regularly throughout the night. I think Pat's foaming of the plenums helped too. How fantastic. My word of advice is be patient, do your own research about the technologies, and work with the right contractors. The ones who responded first did not have my best interest at heart - promoting solutions that were not the best for me simply because that's what they carried. Phone tagging and delays I can handle - that's part of working with people. But when you find those guys who are passionate about getting things done right, stick with them. I'd recommend Pat, Ronnie, and Ernest to everyone (I think it was Ronnie).

It is so hard to get contractors that do what they say they are going to do. Pat and his team were…read morevery patient with me. They gave me a quote in Spring 2016 and due to a family responsibility, it caused me to push the project to 2017. Out of five quotes he was one of two people who came back out to requote the job. He was the only contractor that sent me a quote when he said he would and showed up on time. Pat and his guys came out and removed all the old debris from my attic and installed spray foam. He even went up and above the original plan and resealed our heating ducts and foamed around our light fixtures and air vents to seal them completely. It's only been about a month so I can't yet speak to the cost savings but I can tell you that we have been able to turn our thermostat up 6 degrees and it's still pretty cold in the house. They also installed a whole house surge protector, which is something my husband has wanted for a while. We are very happy with our decision to use Attic Dr.

I…read morecalled him yesterday morning after reading reviews on yelp and he made it out in the afternoon. I thought my HVAC fan motor was broken but it was really just a problem with the capacitor. I would have never known if I tried to fix this myself. I am always hesitant about calling a company to come do work because even the smallest little thing would cost me a few hundred dollars at least. As John was fixing and replacing things, he would also give little informational tidbits and explain what things were and what he was doing along the way. I can't say I didn't learn anything because I did pick up a few things here and there. He was very knowledgeable and definitely knew what he was doing. In the end, I would highly recommend John for all your HVAC needs. He does everything carefully and professionally at a VERY reasonable price.

I want to warn everyone to stay far away from this company. When I was visiting my grandmother in…read moreButler TX, I had a terrible experience with them. The workers were incredibly rude and immediately started talking about charging me just for coming out to look at the issue. When I explained what I thought the problem was, they gave me an outrageous estimate that was double what other local heating and air companies were charging. On top of that, they quoted me a price for a part that can be bought on Amazon for one third of what they wanted to charge. This is nothing but price gouging. It's clear that they deliberately try to take advantage of people who don't know any better. I'm a smart shopper and I always compare prices, so I caught it. But if my grandmother had been alone, they would have robbed her blind without hesitation. That's their business model, preying on the innocent and unknowledgeable. You've been warned: do not trust this company. They are out to scam people.
