  • 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.

Cory - Castle Rock, CO 80104
Review
The technician sent by Nytech was great. He was on time, friendly, knowledgeable and not pushy. The only issue I had was the pricing. Paying $129 just to get a tech. out and then pay another $115 to blow out a 1/2" pvc drain line is a bit ridiculous. Not to mention the prices for modifying the drain lines. Which I didn't do.

Benji gave me a call with an ETA prior to arrival, arrived at the beginning of our schedule service window, and was extremely fast and courteous. He even installed our new thermostat and cleaned our EZ trap (he installed a year prior due to leaks in our system) which was in addition to the service we had him come by for (fuse replacement caused by our DIY thermostat replacement gone wrong). He's great to work with - our landlords use him as well so I knew who to call when we came across a problem.

AC went out just as warm temps came in! One call to Nytech and their pleasant office staff had a tech on his way the next morning! And Colt arrive promptly and quickly identified our issue and showed us the price. With in an hour we were on our way to a cool summer. Colt was a straight shooter with a ready smile. He gave us suggestions on how to even cool between first and second floors and explained his evaluation of furnace and AC w/o. There were no additional charges than the one explained by the office and Colt’s repair work. We even used a coupon from Nytech’ website. We will have them back this fall and are likely to buy their service contract!
Kurt - Castle Rock, CO 80109

Colt went above and beyond with his visit to check our furnace and humidifier. He helped me to find a leak that a plumber was not able (or willing) to investigate! He was so knowledgeable and I appreciate how honest he was about what we needed. I will definitely call NYTech again and ask for Colt!

NyTech technicians call before arrival, arrive on time, are professionally dressed and geared to accomplish the job, have a decent amount of typical replacement parts in their van and demonstrate knowledgeable/efficient work practices. If you are looking for the cheapest resource, then NyTech may not be your cup of tea. But, if you are looking for excellent service at reasonable prices, then NyTech may be the best in Castle Rock.

NYTech did a great job of educating us with options for our leaking,14 year old water heater. We decided to replace it without feeling pressured to do so. They moved us to the top of the list and in less than a week the job was done. And we received a follow up call as to our satisfaction. They were very professional, courteous and knowledgeable. We highly recommend them.

First of all I’d like to say that we appreciate this company having emergency service overnight and on weekends. We had a service call last week from Benji to check our heating system for possible issues since it shut down temporarily during a wind storm. He was polite, respectful and very friendly. He explained his work in terms a nontechnical person like me could understand. My husband and I were impressed by both Benji and the company he represents. Thanks for doing business the right way!

We recently had Colt come out to our house on one of the coldest days where our heat had not been on for over 12 hours. Colt was a true professional and able to help clearly and quickly figure out the problem. He was an all around great guy. Courteous, knowledgeable and communicated frequently keeping us in the know. We cannot say enough about our tremendous experience with Colt and with the company. Colton Made a frustrating and stressful situation so much easier to deal with. We will be using them again and recommending them to everyone. Competitive Prices were an added bonus!!
