  • 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 recently had the pleasure of working with Nytech, the HVAC company servicing Castle Rock, Colorado, and I couldn't be happier with the exceptional service I received. I decided to install an AprilAire 800 whole-house humidifier in my new home, and the entire process was made seamless by the expertise of Nytech, specifically their technicians, Levi and John. From the moment Levi and John arrived, I was impressed with their professionalism and friendly demeanor. They took the time to thoroughly explain the installation process, patiently answering all of my questions. Their knowledge and expertise were evident throughout the installation, and it was clear that they were committed to ensuring the job was done right the first time. Not only were Levi and John professional and knowledgeable, but they also displayed a genuine passion for their work, which was truly refreshing. They worked efficiently and diligently, and the end result was a perfectly installed whole-house humidifier I will greatly improve the comfort of my home. What truly stood out to me was their dedication to customer satisfaction. They went above and beyond to ensure that I was not only satisfied but also educated about the maintenance and operation of the new humidifier. It's rare to find such a dedicated and customer-focused technician, and I am incredibly grateful for their outstanding service. Thanks to Levi, John and Nytech, I now have a reliable whole-house humidifier that will make a significant difference in the comfort of my home. I am beyond pleased with my experience and will undoubtedly be turning to Nytech for all my HVAC needs in the future. If you're in Castle Rock, Colorado, and in need of HVAC services, I wholeheartedly recommend Nytech for their exceptional professionalism, expertise, and commitment to customer satisfaction. They've earned a loyal customer in me, and I couldn't be happier with the outcome of this project. And a big thank you to the entire Nytech team!
