Super professional, highly qualified & fit to my needs

Benji was super professional, highly qualified, friendly and thorough. He patiently went over all the aspects of my 26 year old furnace service and all options going forward. He showed me how to clean my filters, even let me video it for later reference and explained all the things that were recommended, but never felt pressured to buy anything that I am not ready for. I highly recommend Nytech and will continue to work with them for all my heating and cooling needs.

5 Stars

From dispatcher call to paying the bill and closing the door, the service exceeded expectations. Dispatcher and Brett were very friendly, professional, prompt, and efficient. Brett could have given me a huge sales pitch on our 1983 furnace but instead showed me how to reset the furnace. (We had another company over Friday and they proposed replacing the gas line and were super heavy on sales-my husband declined service.). I brought up a new furnace out of curiosity and Brett gave me a ball park estimate, which sounded reasonable, but I was extremely appreciative of Brett’s honest professional assessment and nature. That right there topped off the whole experience. Before Brett arrived, I did tool around a bit on their site and found the company a bit impressive—service within 24 hours guaranteed, coupons, rebates, maintenance plans, and financing, of course. After the storm and no heat, I was just surfing for a heating/cooling company still open on Sunday evening to get our furnace working. Instead, I found OUR long term heating and cooling providers! Nytech and Brett exceeded service expectations. Sold!!

Helpful Service

Benjee was helpful mentioning several suggestions regarding our hvac unit. Although he didn’t have the part to an old humidifier he found the part and emailed it to us so we could pick it up and offered to install next time they were here.

Exceptional Service

Colt and Mike were thorough, honest, and kind. Even though we had a larger job, they worked quickly but did not hastily rush through the work. I am not an HVAC expert by any means, and they explained everything in a manner that I could understand, but I never felt patronized of “swindled.” We’ve used Nytech for years, and the service and expertise standards are always met with excellence.
