  • 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.

The techs are knowledgeable, friendly and professional. Many years ago, Nytech installed my furnace, air conditioner & humidifier with wonderful results. I hired them again to replace my humidifier that went out of warranty. The techs know their stuff, they go above and beyond and they are excellent at customer service.

Benji was great. very kind and efficient with our service. he went above and beyond taking care of a problem with our thermostat as well as advising us about a problem with our humidifier. he was unable to fix it at this time due to lack of parts but have no doubt it will get done.

Everything about the appointment and service exceeded my expectations! Easy to make an appointment, very responsive, on time, phone call and text that they were on their way, upfront pricing, very friendly and knowledgeable technician. The technician (Ricky) is very knowledgeable and helpful and answered all of my questions. He had the part available on his truck and he was able to get things working again quickly! I will use them again with any future HVAC work.

Our water heater went out and Benji made it over first thing in the morning. He was prompt and professional, as well as very friendly and good at relaying what was going on with the water heater.

Review
This was the 3rd trip for this issue. I believe the last trip the problem was missed and it put a lot of extra wear on the new pressure valve on h2o tank. Therefore the rating for cost /pricing.

Ricky was very friendly, he kept me informed on what he was doing. He was very nice to my 3 senior, barky dogs, and he wore protective shoe coverings when he was inside my home. He seemed to do a very thorough check on my AC units. I appreciated all his work. He deserves a Yeti cooler ;)

Brennan came to do a check-up on our furnace. He was friendly and courteous. He efficiently identified a few areas that needed to be taken care of and did a thorough check of the whole system.

I had NyTech come out to evaluate an ongoing issue with our heater. While other companies just recommended a full replacement of the system, Ricky did a more thorough inspection and identified the root of the problem. He provided a series of options to resolve the issue. He was knowledgeable and not only explained the problem but showed us. Nytech has been the best service company that we've used in Castle Rock.
