  • 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.

I worked in the service industry for 30 years so I think I know good customer service when I see it and I was very impressed with Benji's service, he was courteous, knowledgeable and efficient ( I was very impressed with how quickly he diagnosed and repaired my furnaces problem). He even took the time to show me ways that Nytech could help improve the efficiency of my existing heating system. Benji is definitely an asset to your organization.

We have been using Nytech for almost 2 years now and have been very happy with their customer service and response time. We are members of their Total Care Club and feel it has been of great value to us. It makes servicing and maintaining our HVAC and Humidifiers very easy. The techs are always very knowledgeable. I feel that they do a great job fixing any problems and always warranty their work. The annual service is great way to keep things running smoothly and tackle preventative maintenance before things break down.

Benji was super friendly, very knowledgeable, and very thorough in his assessment of our AC issue. He didn’t pressure me into anything, let me know my options, and helped me weigh the different options that we have for a fix. He was thoughtful enough to ask if we had a sleeping baby when he saw the high chair so he didn’t wake them, and asked about our dogs and whether they could be outside with him or not. That may not mean much to some, but when we’ve had multiple people doing work in our home where they have kept our gate open so our dogs got out, it meant a lot to me. He explained so much about our different options that I was able to make a good decision for a path forward, and if I had questions that he felt someone else at their company would be able to handle them better, he offered to have me talk with them and was honest about he extent of his knowledge. It was a great experience!

Benji T did a fantastic job on diagnosing the issues and completing a repair that saved us from the 90+ degree heat. Had the replacement part that was needed on his truck and also did a full system evaluation. Having Nytech come back to quote replacing some aging hot water heaters as well. If you want to go with someone who is honest and expedient, you can't go wrong with Benji T and Nytech!

Reese was so great to work with. Very professional and great responsiveness. Murphy’s law says that what may happen will happen so when your air conditioning goes out during a heat wave, have these guys in speed dial.

It was a pleasure to deal with Brett. He is a thorough professional and extremely courteous. I had had a very unpleasant experience dealing with the home warranty insurance company who had sent a technician who quoted an outrageous price. I thought about buying a new central air conditioner, instead, considering how much it would cost. Brett gave me such a reasonable quote that I found it hard to believe. Got my air running within no time. Please call Nytech for all your heating & cooling needs!!
