  • 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.

We appreciate Brayden and Nytech for a quick response and resolution to our problem. Thank you!

Ricky and Gage were on time, so professional,courteous, and friendly. Ricky took time and explained what the findings were with regards to my annual AC check. He provided me with options and packages. Gave his opinion as to what needed to be replaced and why but I absolutely felt no pressure. I trust what Ricky suggested to help maintain and extend the life of my AC unit. Great experience. That’s why I’ve chosen Nytech.

Review
Ryan came to my house because of a water leak on the humidifier attached to my furnace. The unit was not accessible as it was buried behind other things in the equipment room. He was able to turn off the unit so that it would no longer leak. Because it was such a simple temporary fix, he told me I wouldn't be charged for the service call. He was very nice and I appreciated his honesty. Nice man. Thank you!

Ryan is absolutely exceptional! I scheduled a seasonal tune up and requested him specifically based on a previous experience when he came out to service my HVAC system. He is extremely knowledgeable and easy to talk with, always happy to explain everything in as much detail as I’d like (and I generally like the details) and very conscientious about making me feel comfortable with him being in my home. I trust his judgment completely on the care and maintenance of my water and air systems. Thank you, Ryan!
