Comments: Mr. Nichols and his team are wonderful. My AC hasn't been blowing cool air and I called Air Trust in the morning to obtain a quote. Mr. Nichols came by that afternoon to gave me a diagnosis. My unit is 18 years old and on its last breath. He gave me replacement options and the pricing was very fair. His team showed up early the next morning and knocked out the job in less than 3 hours. Everyone was professional, knowledgeable, kind and patient answering my many questions. I highly recommend Air Trust for your HVAC needs.

Comments: Mark was very knowledgeable and explained his services well. He came out within 24hrs to install my new hvac system when it was below freezing. He and his crew did a nice install within a couple hours even while having to having to adjust some ductwork. His reviews are spot on and I'm so happy we chose Airtrust!!! My family is now very comfy and warm. Thank you Mark!!

Comments: Mark did everything he said he would do when gave the estimate. Had a great team, didn't take long. My concern was trust,and I would definitely refer them to anyone.

Review Date: 01/27/2016 | Author: Logan B.

Comments: Our HVAC died on a cold evening - I arranged an appt. online through Home Advisor for noon the next day. Mark Nichols called me 5 minutes later, walked me though a couple of troubleshooting steps I hadn't tried, and then told me he'd be there the next morning by 9am. When he and Alan diagnosed that we needed to scrap our 14 year-old unit and install a new one, they were able to get the new one over to us a couple hours later and completely installed two hours after that, all for less than we anticipated paying. Courteous, fast, professional, I'd recommend them to anyone.

Review Date: 01/20/2016 | Author: Scot M.

Comments: They were very professional and courteous. Diagnosed the issue, gave us options and told us what the cost would be for each. Fixed the issue and we will definitely call them again when we have to replace system. (Which, thanks to them won't be as soon as it could have..)

Review Date: 08/20/2015 | Author: Lee C.

Comments: I have been in the construction business for many years in two states. Very seldom do you find a company that is completely on point and AIRTRUST is. Mark Nichols plays NO games he looks at your issues and gives you a direct solution with a price right on the spot, he advises you in a professional manner and he and his company get to work and get's it done. I would recommend AirTrust to anyone and they will get to see what we seen. Service the way it used to be. We are 100% satisfied. Lee Mickler-Creech Louisa Bowers

Comments: I was very impressed with Air Trust HVAC. They were able to figure out the problem with my AC quickly, and took care of it right away. They were fair and honest, and didn't try to talk me into additional services that I didn't need. I will certainly call them again when I'm ready for regular maintenance visits for my heating and AC systems.

Review Date: 06/19/2015 | Author: Pamela P.

Comments: Great team! Reading the reviews, I thought, who gets 5s on all reviews? Well, I can see why. They provide excellent service. No double talk and no pressure to buy. They replaced what needed to be replaced and didn't try to talk to me into buying more than I needed. Customer service...excellent!! Mark even sent me a text the next day asking how the unit was working (an added personal touch). I would recommend them to friends and if ever in need again, I would certainly give them a call. We are very satisfied customers!!

Review Date: 06/10/2015 | Author: Patricia A.

Comments: Awesome! I arrived home last evening to a non-functioning AC... it got hot inside!! I requested early AM service from Air Trust via the online link on Home Advisor and had a call from them; a visit from them; and a completed repair all by 8:30 this morning. I liked the gentleman who performed the repair and will definitely use them again. Instead of just correcting my problem, Carl went above and beyond to check to make sure there was not more to the problem than was apparent. The cost was very reasonable.. much lowere than I anticipated. Thanks!!!

Comments: great people to work with

Review Date: 04/21/2015 | Author: Christopher E.

Comments: I'm not often compelled to write reviews, but definitely wanted to in this case. My AC unit went out this month (April), which left me praying for seasonably cool weather and a good HVAC installer. I gathered a few quotes, and the amount of the quotes didn't vary by too much. So the decision came down to who I got the best feel from, and online reviews. In both instances, Air Trust was the leader. Based on that, they were hired. And that was a great decision. The day of the install, the first thing that the father (it's a father/son team running this small business) said to me was, "good news! I got a lower rate on your unit, so that'll save you $200.". There is NO WAY I would have been able to know that if he hadn't told me....he could have pocketed that without a problem. This kind of honesty and customer service just isn't common nowadays, and that's too bad. In addition, he saw that the grate on my intake unit wasn't big enough for the site of unit it was servicing, so he took it upon himself to go and purchase a new grate for me & install it. This wasn't part of the original conversation, but he did it because he knew it would help the system's performance. If only I could find people like this in every facet of the home repair industry, I would be a happy man.

Comments: They did a quality job at a reasonable rate.

Review Date: 02/24/2015 | Author: Eric R.

Comments: They communicated well, they were prompt, and fixed the problem in the most cost effective method possible. I appreciate their assistance with my older furnace.

Comments: Pleasant employee's with smart planning of the job. Removed old unit in the afternoon. (Back at 8:00a.m.) New heating and, cooling unit installed by noon! Mark, was very honest about our needs, very prompt!

Review Date: 02/05/2015 | Author: Bruce L.

Comments: Mark Nichols was straightforward in presenting his information and once we agreed on the installation, he and his crew did exactly what they said they would do. The system works well and we think we got a very good deal.

Review Date: 02/02/2015 | Author: Diana I.

Comments: My outdoor compressor unit stopped working so I called Air Trust HVAC and spoke with Mark Nichols and informed him that I needed a new unit. To add to the problem, I was leaving for out of town and would be gone a week. Mark was able to make the necessary arrangements to accommodate the urgency to install my unit the next day, before I had to leave. Great customer service! What a relief!

Review Date: 02/01/2015 | Author: Ken W.

Comments: This company had an experienced crew. They knew their business.

Review Date: 01/20/2015 | Author: Bill W.

Comments: Mr. Nichols was the most transparent of the contractors we received bids from. He sold us what we needed at a very fair price.

Review Date: 12/14/2014 | Author: a Neighbor

Comments: They did what they said they would do when they said they would it. No surprises or extra costs.

Review Date: 11/13/2014 | Author: Brian L.

Comments: Mark and his team were a pleasure to work with. He contacted me via phone about 10 minutes after I completed the Home Advisor request. He came out to my house that morning to inspect the packaged unit that needed replacing, and called me up with quotes for multiple units to consider. I had specified a particular unit, but he recommended I go with a more affordable unit with a better warranty. I did my own research after that, and came to the conclusion his recommendation was the right one. Not too often the person selling a product talks you into a lower-priced product! They were at my house the next morning, got the unit replaced in about 3 hours, and we have been living comfortably since. Mark's prices are very reasonable - being able to compare apples to apples, you realize how much markup some of the larger companies have. I will happily recommend Air Trust HVAC to anybody I know that needs work done.

Comments: I needed my gas furnace cleaned. He was able to come out that day and was even there a little early. He cleaned the unit. However, I felt that he was trying to scare me into buying a whole new heating and air system. He told me it was going to go out at the worst time and he might be too busy then to fix it right away and that I should just go ahead and spend the $4,000 to get a new one. I said I couldn't afford it and he told me where to get a loan. While I know they always go out at the worst time, it is working perfectly now. I've never had a problem with it. On the good side, he gave me lots of helpful information about replacement. I just didn't appreciate that kind of pressure. Also on the good side, he didn't lie- it will indeed go out one day. He didn't say that I needed something immediately or else.

Review Date: 10/10/2014 | Author: Becki D.

Comments: Used Home Advisor for the first time after the HVAC needed replacement. Initial estimate from reputable company I've used several times before was $$ and the manager left me feeling hurried and stressed (it was not an emergency, but did need to get done in a timely manner) Within minutes after completing the Home Advisor info, Mark Nichols, owner of AirTrust, phoned. His manner was courteous, professional, not pushy at all, and his estimate included the same Brand,warranties,etc. and $1700 less! A 3rd estimate from HA offered same as above, and even less $$, it just didn't 'feel' right. When I phoned the initial company to inform them of my decision, the manager asked if he could 'sweeten the pot' to change my mind. Politely, I declined. When he asked how much $ his competitor was going to charge, he dogged the competitor (Air Trust, but he didn't know who I had hired)! Said there had to be something wrong with him! Well, AirTrust installed the unit the next day without a hitch. I would use them again in a heartbeat. Trust your instincts. It helped me!

Comments: Mark Nichols, owner of Air Trust HVAC, is one of the kindest professionals I've worked with in decades. He's an honest, courtious, and a man that will handle any job wonderfully. I highly recommend his company vs any other HVAC in the Nashville area. At no additional charge, He corrected a vent that had been mistakenly placed in a closet vs a second bathroom. Same day as well. Please don't hesitate to call them when you need a repair/replacement on electric, plumbing or HVAC work. Mark Nichols is the ONLY one I highly recommend!

Review Date: 09/06/2014 | Author: Samantha S.

Comments: Mark was really great to work with. Fair pricing and very prompt. He was able to get a new HVAC unit installed before noon the following day. I would definitely recommend Mark.

Comments: Air Trust gave a quote, beating all others, including meeting or exceeding all warranties. Installation of the 3-ton unit to serve our upstairs was fast and they did an excellent job cleaning up afterward. The key difference is that I felt the company was concerned with more than selling us a unit, they were concerned with solving the problem we've had for several years upstairs. It's been a month and the problem seems resolved.

Comments: Had 3 or 4 different companies come out an look at our hvac unit, as the heat exchange had gone out on our 13 yr old unit. Not only was Air Trust the best value for the money, but they were by far the nicest as they made everything clear and easy for me to understand. They were also able to install the unit the next day, and were done very quickly. Would recommend them to anyone.

Comments: Mark Nichols called immediately after my online request was submitted. He answered all my questions. I could hear the experience in his voice. I asked when he could come to look at my system and he was at my home in 30 minutes. He explained his analysis of the problem. He repaired the system quickly & efficiently. I will definitely use him to maintain my Heat. & Air Confitioning system for years to come.

Comments: Look no further than Air Trust Hvac. Mark is knowledgeable and spent time with me on the phone explaining troubleshooting steps at 8pm. He even offered to help me get the necessary parts. Mark is fair, honest and a true rarity in today's A/C service industry. I wholeheartedly endorse his services.

Comments: My 23 year old heat pump finally keeled over and died. Air Trust was ready to go. They were fast in getting back to me when I asked for a quote, The work is quality. It not only works well but it looks good too. The price was also much less than my other quotes.

Comments: My air conditioner went out during the hottest week of the summer (of course). I was quoted by a bigger, well known company $5500 to install a new system. I searched for a another company to get a quote from and I stumbled upon Home Advisor. I completed the online questionarre, submitted it, and less than 5 minutes later, Mark called. He came that next day and quoted me a much reasonable price. He was amazing! and VERY knowledgable. I will recommend them to anyone.

Review Date: 07/03/2013 | Author: Kevin J.

Comments: Mark called me with a minute after going through the steps at Home Adviser. Mark came to my house that afternoon and was able to get my A/C running again. The previous serviceman wanted to replace the A/C unit costing $5,500. Mark was a lifesaver.....he is prompt and very honest. Will recommend him to all my friends and neighbors.

Review Date: 03/04/2013 | Author: Kathleen D.

Comments: Wow. Our heat was out during a very cold streak. Mark came out immediately, assessed our needs, and provided a quote for a new system (which we knew we needed as the existing system was 30 years old). We received 3 other bids, but the combination of the unti, work, and warranty (definitely best warranty as far as labor) compelled us to choose Air Trust, and we couldn't be happier. Knowing that we had no heat, he started the job immediately (the next day), expertly worked around a very challenging location for the placement of the units, and provided a quality installation. I will use him for any service needs, and will recommend him to all.

Review Date: 02/15/2013 | Author: a Neighbor

Comments: Mark was excellent at customer service and called immediately to discuss replacing my unit. He came right out and looked at my unit and provided me with an excellent and had it replaced any running in no time. I think they did a great job and would recommend them to family and friends.
