Outstanding Service

Benji is very knowledgeable. He answers all questions in a very understandable way. Benji thoroughly explains what he does, and also explains all of his recommendations. A pleasure to work with him.

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.

Fantastic Service

Benji and Dylan were fast, thorough, and extremely caring. Our furnace is an issue and have gone through two other companies. This service beat those hands down on friendly service, knowledge, and pricing. We would highly recommend them!

Great Service

Benji arrived on time, was very helpful and thorough and willing to try to figure out the problem with our aircon that wouldn’t cool properly. Very fair pricing, didn’t hard sell, explained issues well.

Amazing service!!!

Nytech went way above and beyond my expectations. I woke up Sunday morning to no heat. I called nytech in the morning and was told my tech would give me a call when he was on his way. My tech Benji called 20 minutes later saying he was on his way. He even asked if he could stop off and get us coffee cause he knew we were cold and asked where I preferred he parked his van! You just don't get that kind of service anymore. Found the issue and got the furnace working until my new parts came in. Im glad I found nytech. I tell everybody about my experience. Nytech has a customer for life!

Amazing service and price

Benji was awesome. Very polite, professional, and efficient. Did a full inspection of our issue, laid out all the options for us, and didn’t force anything. Excited to be apart of the new service membership.

Exceeded expectations!

From the time I booked my appointment with Nytech, to their follow up phone call to check on us, to the service tech Benji, I was blown away by their customer service. Benji did a great job explaining what he was doing to get our heat back on and made some helpful recommendations to improve our system. I will be going with them from here on. Thanks again.

GREAT service on my humidifier.

Benjie was very knowledgable about the wiring of my humidifier but because some parts were missing, he called the manufacturer. After explaining the problem, the tech at Aprilaire agreed to send the missing parts free of charge.
