“GTS assumed maintenance of our HVAC system from a previous company. It was a lot to figure out – even we were confused by it all, and it's our house – but GTS has solved every problem we've presented them with in a thorough and professional manner. We're more than happy to have them as our primary HVAC service provider, and look forward to a long, sustained relationship with Tammy and Greg.”
- Jeremy and Michelle Lang

“GTS HVAC, Inc made several changes to our system (which was not installed correctly prior to this) and it has made a world of difference in our house. We don't need 5 blankets to keep warm now that heat is getting to the rooms we need it to! We have noticed a decrease in our utility bills as well. We were very impressed with the work and professionalism. GTS HVAC, Inc. also worked hard to diagnose a problem with our humidifier and it has made a world of difference. The system is actually working like it should. I have recommended GTS HVAC, Inc. to our neighbors and friends”
- Richard, Forest Lake, MN

“I was having issues with my air conditioner and had two "other" service companies out to assess the situation, one told me I needed to spend $6000 to get a new one and the other service professional said he would just add freon and that was all he could do, which did not help. Greg with GTS HVAC came out and found a hole in the hose and replaced it and I haven't had any problems since. He was very professional, honest and went out of his way to explain and give information about helping my system work more efficiently. I would never call anyone else! I highly recommend this company!” 
- LeAnn L., Brooklyn Park, MN

“Our facility required a constant room temperature and air quality levels. It has multiple zones, and highly variable air quality components. After talking with numerous heating and air companies regarding my specific needs...which came as quite a challenge to each of them, I was tired of hearing the word CAN'T. I called GTS and Tamara was quite sure that they could deliver a solution for my tough challence. Refreshing to hear! From the start they were very responsive, listened to my needs and met my expectations. GTS' quality workmanship and knowledge of the new, efficient technology was what RRC had been searching for!”
- Charles Rauenhorst, President of Rauenhorst Recruiting Company, Minneapolis

“Greg and GTS are an incredible package: thorough, knowledgable, considerate, prompt, efficient, cost-effective, very professional and a pleasure to work with. I've never run into a better contractor, subcontractor or vendor in the quarter century of working in the real estate and construction industry. We recommend GTS HVAC, Inc. unconditionally.”
- Donna and Ken Engel, Minneapolis

“I would recommend GTS for all heating and air conditioning needs. My first experience with GTS was on the installation of my new home's heating and air conditioning in 2004. Since then, I've recommended GTS to both my boss and my mother because of the skill, honesty and integrity that they bring to the table.”
- Gary N., Minnetrista

“This was the first house I built and generalled on my own. Working with GTS from early on in the bidding process to the follow-up once we were living in the house made the HVAC component of the construction a good experience. I received top quality, professional service and top of the line HVAC equipment - all for a valued price. I strongly recommend GTS for your HVAC needs.”
- Steve Lillehaug, Chanhassen

“GTS HVAC, Inc has proven to be prompt, efficient, courteous, and cost effective on every residential and commercial project I have worked with them on. These qualities are hard to find with many of today’s contractors. I would highly recommend them for any project size and type.”
- Dan Meeker, Architect

“I had worked with Greg Sundby prior to building our 81,000 square foot office/warehouse. GTS HVAC (Greg) provided me a good value from design, installation and service. This building project was an important project for Delta Industrial Services, Inc. When choosing GTS HVAC, Inc., our decision was based on our past involvement with GTS HVAC and Greg for there knowledge of application for design, courteous service minded attitude, and competitive pricing. I am pleased with our decision, and would recommend Greg and the Team at GTS HVAC, Inc. for your HVAC needs in new construction, tenant build out, and service again.”
- Dave Schiebout, President, Delta Industrial Service Inc.

“GTS HVAC did a great job for me.  This was a complicated house and they installed a sophisticated heating and ac system that had to be retrofitted into an architectural plan that made for large open spaces.  So GTS had to be careful where they placed things and they accomplished this with real finesse.  Further, they also installed five gas fireplaces throughtout the house and a difficult kitchen downdraft vent for the cooktop along with an air exchanger in the basement.  GTS was very knowledgeable, easy to work with; bringing good solutions along with the problems they identified, and best of all they showed up when they said they would.... and I really appreciated that relability.”
- Marshall Masko

“GTS HVAC gets an A+!! We called for service regarding a furnace issue we were having and Tamara spent quite a bit of time on the phone with us before and after our furnace tune up (never making us feel like we were taking up too much time or asking too many questions.) They were honest (we were expecting a big repair but there ended up being no issues!), prompt in communication and friendly. They also knew what they were talking about. We will call them for any HVAC service needs in the future - they are great!”
- Erin C., 1 review

“Great job getting us through the cold spell without any major incidents! I think Minneapolis was the only district in the Mid-West last week that didn’t have frozen pipes/floods.”
- Sean Conner | Facilities Coordinator/ Wireless Vision

A BIG THANK YOU to GTS for taking care of our furnace inspection last week. Thank you Greg for finding a way to have Heath come over and Thank You to Heath for doing the inspection and figuring out what was wrong and fixing it.  Thanks again guys. We really appreciate it!
