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

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!

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.

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!

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.

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.

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 and his son were very proffesional and explained my problem very well. The pricing was fair and unit is woking well now.

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!

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 provided best quote as well as was best at explaining the cost/benefits of the different AC units. Fast too.

Review Date: 07/24/2014 | Author: Barbara O.

Comments: Most competitive price; same day service. No high-pressure sales!

Review Date: 07/10/2014 | Author: Robert T.

Comments: Arrived as scheduled and fixed our AC unit within 2 hours. Also gave us valuable information regarding the nature and cause of the problem, along with suggestions to avoid the same problem in the future. Very helpful! Will use again, and would recommend without hesitation.

Comments: Quick professional service.

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.

Review Date: 12/27/2013 | Author: Seth C.

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: I'm a first time user of getting bids on the internet, but after my experience with Trust Air I'm hooked. They were fast, friendly and performed quality work. The price was $2K below the local big names. I'm happy, happy, happy and warm.

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.

Review Date: 10/15/2013 | Author: Bill E.

Comments: Replaced 15 yr old outside gas pack within 4 days after accepting bid, which was hundreds less than competitors. Installation completed within 3 hours. Very satisfied and will definitely recommend Air Trust in the future.

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.

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.
