  • 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 am a new customer to NYTech. We had Luke come and fix a plumbing problem for us a couple of weeks ago. He did an excellent job and was very professional. He signed us up for the Care Plan. Tyler was very professional as well. He is a great representative for the company and we were very impressed with the service we received from scheduling the appointment and the follow up.

I recently had the pleasure of having Robert Schultze from NYtech Heating, Cooling, and Plumbing conduct a furnace inspection at my home. Robert was incredibly professional, thorough, and friendly throughout the entire process. He took the time to explain everything he was doing and ensured that I understood the condition of my furnace. His attention to detail and dedication to providing excellent service were evident. I highly recommend Robert and NYtech for any HVAC needs. Thank you, Robert, for your outstanding service!

Tyler and Jamee worked all day to replace the compressor in my AC. I have so much respect for their skill and knowledge but in addition they were cheerful and respectful the entire time. They explained everything clearly and double checked their work to make sure it was done correctly every step of the way. Because of the experience I had today, I will use Nytech for all my HVAC needs.

Ted - Castle Rock, CO 80104

I cant say enough good things about Tyler. I have an old A/C unit on life support (over 20 years old) and Tyler has been the guy keeping this beast alive. I have used Nytech several times now and they clearly have a good business operation going as they have amazing techs and their prices are not crazy for the work they do. As for Tyler, love his personality, integrity, and ability to diagnose the problem fast. Nytech could hire 100 Tylers and be just fine. Thanks for the hard work today Tyler! - John E (Castle Rock / Meadows)

This is the second time I have used Nytech for my HVAC needs and both experiences have been excellent. The office staff, scheduling and notification process and technicians have been outstanding. I most appreciate the transparency they provide around the issues being experienced and the pros and cons (costs) of various options to address. No hard upselling of more expensive repairs.

Tyler was great. He quickly diagnosed the issues with our AC and had it up and running quickly. Our hot water heater was leaking and Tyler checked everything out and found out that ours was still under warranty. He ordered a new one and when all the parts come in, it’ll be installed this week. I’m very happy with the honesty and professionalism of NYTECH. I highly recommend them.
