Best Heating & Air Conditioning / HVAC In New Ulm

“All I can say is WOW. Super friendly, super quick service and my bill was less then half of the estimated quote. Way happy with them.“

“After years of slapping bandaids on my home’s HVAC system just to get by, we finally bit the bullet and had Sam arrange for us a total revamp- new ac, new furnace, and adding an second vent to each of our 3 upstairs bedrooms. Also zoning our home into two sections. After some tweaking of the system, this crazy summer heat has passed us by without us blinking. I haven’t needed to change a thermostat setting or anything for weeks through this heat. It’s so satisfying just having a system that works!! And Dustin performed some type of magic getting ductwork almost 20 ft through my ceiling without tearing out all of the Sheetrock!! Definitely recommend this crew!!“

“Dale was very friendly and knowledgeable. He also likes my dog, Karl. Karl was stuck to him like glue. Practically had Karl taught to hand him the proper tools. Anyway, Dale has been to our place many times and always has a solution to our fireplace problem. Highly recommend!“

“I had a major water leak in the Basement (water was gushing out of one of the pipe) last night around 9:30 pm and Josh who answered my call sent Nate for us to fix the leak right away. I was impressed and appreciative of their quick response to this emergency and especially Nate's skills and knowledge. Thank you.“

“GSM was incredible to work with! They are always highly recommended around town, so they were the first ones we called to scope a sewer line and quote work. They came in $8,000 below another company in the area, who quoted us work that didn't need to be done. GSM is honest, timely, and easy to work with.“

“We called them last minute to service our AC and they were there to help us quickly. Very satisfied with their professionalism and advice for future maintenance.“
