  • Full System Replacement – Fareham Court in Castle Rock
    Full System Replacement – Fareham Court in Castle Rock

    A longtime customer of ours who is also a Total Care Club member scheduled their annual heating maintenance appointment for their 19 year old furnace. Like every maintenance appointment, our tech performed a combustion and heat analysis and discovered that the blower motor was leaking oil and ignitor was flecking. They spoke to the homeowner about the pros and cons of repairs vs replacement, and the homeowner decided to move forward with setting up a comfort consultation for a furnace replacement. The techs at Nytech replaced both the furnace and air conditioner and added a humidifier and new Sensi-Touch thermostat for the ultimate upgrade in home comfort. The Lennox furnace is a standard efficiency, multi-stage variable speed furnace and the Lennox a/c is a single stage, mid efficiency air conditioner. This new system is backed by our Golden Guarantees.

  • Daikin Furnace Replacement – Coach House Loop in Castle Rock
    Daikin Furnace Replacement – Coach House Loop in Castle Rock

    We were called out on a no heat repair call on a cold March day and got straight to work. Upon diagnosis, our techs discovered the induced draft motor spinning without load, which was caused broken fan assembly pieces inside its housing. They also noted rust on the top of the blower deck, which lead them to inspect the secondary heat exchanger. To their surprise, they discovered the secondary heat exchanger had failed, which brings the potential for the furnace to have carbon monoxide related issues and/or flame roll out issues. Both the induced draft motor and the heat exchanger would need to be fully replaced in order to bring system back into safe operation. These repairs exceed the value of the furnace, so it was recommended to replace the furnace instead of repair, and the replacement was scheduled for the next day. We replaced their furnace with a high efficiency Daikin furnace and custom plenum. This new system is backed by our Golden Guarantees.

Our water heaters were near end of life. Wanting to have hot water and avoid disaster, we called Nytech. They came and gave us a quote on several options. Once we decided on which route to take, parts were obtained quickly from warehouse and install date was set in a matter of a few days. Levi and team arrived, prompt, pleasant, answered all questions re the install, and they got to work. Great job! Everything was left clean, and they provided a full explanation on functions. Set up required inspection as well. Cant rec these guys highly enough. Many thanks!!!

I've had Benji out twice to check out my furnace. Both times he was courteous, knowledgeable and completely professional. He explains things thoroughly and in a way I can understand. And he always provides me options about how to proceed. It's a pleasure working with him, and Nytech is lucky to have him.

Dylan from Nytech Plumbing was phenomenal!!! He was willing to adjust our appointment time when I needed to rearrange so that I could get my kids from school. He was able to find the issue with my plumbing which was causing a slow leak. He also fixed a sink that needed minor repair. The service was quick, friendly, he fixed the problem and was affordable!

Nytech has always been quick to respond to service requests. Brayden arrived on time as scheduled. He clearly and professionally communicated the problem I was facing. He quoted me a repair price. I'm guessing that I probably could have gotten a "cheaper" bid from another contractor if I called enough of them. However, I'm a big believer that contractors should be judged on a few things. Do they show up on time? Do they do good work and stand behind their work? Do they complete the work at the price quoted? Do they complete the work in an agreed-upon time frame? Are they clean-cut and courteous while in my house with me and my family. Brayden and Nytech get stellar grades to all of these questions. Based on my experience with other contractors, in general, this is not to be taken for granted. "Cheaper" sometimes turns into a nightmare. It's why we call Nytech first when a plumbing/HVAC need arises.

This is the 3rd time I've had Brauden here for different plumbing servicrs. He has always been friendly and respectful, very detailed and knowledgeable, and not only prompt but completes the job in a very timely manner. I really wouldn't think of having anyone else come to take care of my plumbing needs. Thank you Brayden and Nytech.

I had the best experience form the technicians at Nyteck heating and air-conditioning in Castle Rock. At one point there was a mistake made. I was so proud to find these young men who told me of the mistake. They informed the Owner of Nytech of the mistake take they made. With no issues with the owner, he said he would take care of everything. Levi Taylor and Mike Mizek were very honest a quality not found very much these days. They were very pleasant to work with. So glad this is a good company and really take care of the customer. The worked stopped and the owner sent a repair man out and fixed all. Had had a good price for a new 96 percent furnace and air-conditioned. I WOULD RECOMMEND THIS HONEST COMPANY AND MEN Again Thank you. Mr. & Mrs. Peterson

From the first experience to the last you can tell the culture that stems from the top down. Every interaction was pleasant, empowering, and valuable. Bento was AMAZING to work with. Both my wife and I work from home and have 4 kids. Him and his partner both interacted with the kids and communicated their process and what was happening each step of the way. Would HIGHLY recommend them.
