"Great service! G&C worked around my availability. Tech was super knowledgeable and professional. Fixed the problem and gave great maintenance advice."

"They contacted me right away, set up an appointment, came and did a wonderful presentation that was on a Tuesday. I had other contractors in between. They already sent me their estimates. I waited till that Saturday. And I emailed him, that I wanted to get his estimate. Never received anything. The following Monday, I called his number. He never got back with me. I told him what I wanted. He never got back to me. On Tuesday, which would have been a week after he was here. I called H L Bowman, and spoke with somebody there. She said she would check into it, and she would have an estimate to me within a day or two. And they never got back with me. I never got an estimate. And we checked our email address. Make sure everything was good. Never received anything. And here it is like, over two weeks later and havent heard a word from them. "

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

"Great, as always. Sila is outstanding. We have a service contract with them for our furnace and AC and they keep them in tip-top shape. And when we have an urgent or emergency situation (heating, cooling, plumbing, electrical), they're who we call."

"BEWARE OF THIS COMPANY I purchased a brand-new heating system for $15,000 in September 2025. The system came with a one-year company warranty in addition to the manufacturer?s warranty. Despite being new, the system malfunctioned four times within less than six months ? on December 4, December 6, December 17, 2025, and again on February 14, 2026. Why would a brand-new $15,000 heating system fail four times in less than six months? Each time I called the company, the response was slow. I later learned they do not provide evening, weekend, or emergency service. This was during the heart of winter, and I was completely at their mercy to service a system that was still under warranty. When I requested to speak with a manager, I was consistently blocked. The secretary or office staff always had an excuse as to why no manager was available. There was never an opportunity to address my concerns directly with leadership. The company presents as polished and professional when selling the"
