Nick and his team, Juan but especially Xavier, provided OUTSTANDING service!! Our AC unit wasn’t working after many service calls. Nick the owner dropped everything as temps were in the mid 90s. His expert team (Xavier and Juan) diagnosed and fixed the problem as Nick ran interference with the tech support folks at the manufacturer. ...

Nick and his crew are absolutely the best in the industry. I have been an HVACR contractor for over 40 years and just too old to work on my own equipment. He is the only guy I trust to work on my equipment

Have been using NSG for the past 4 years. Their service team is spectacular…..!! Service calls are quick and efficient. Have the annual maintenance plan – tech’s only replace parts as needed, but always advise “what we need to keep an eye on” Highly recommend

Nick and his crew are top notch! They recently replaced our outside unit. They evaluated our system one day and had it running again the next. I am so thankful that I had a working heater through the winter storm we just endured.

This is a great team. During the February 2021 Texas winter/ice storm, our old furnace went out from power surges. Nick was at my home within 2 hours of calling. He submitted his report to my insurance, and the next day a new furnace was installed. Thank you for returning heat to my home so ...

I’m a local REALTOR and one of my clients installed the thermostat incorrectly after removing the Nest.
