  • 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.

Brett, diagnosed my furnace issue quickly. He offered the option to have me replace a part or wait and see if the issue happened again before replacing. He also offered a service maintenance option. This made the most sense in relation to price what was covered. Thanks Brett!

Benji is awesome! My furnace was not working and he quickly diagnosed and fixed the problem. He also spent time explaining to me some issues he saw with the furnace motor and took the time to walk through options. Thr service was great and I recommend Nytech if you are looking for a reputable company to service your furnace or air conditioner!

The customer service was awesome. Two people provided service and they spent nearly two hours servicing and inspecting my furnace and water heater. All was really looking for was maintenance and a safety check. The fact that they spent so much time was good and bad. I knew to expect a hard sale. So be prepared for great service and know in advance what you are willing to pay for. Note they did provide excellent service to my furnace and water heater.
Richard - Castle Rock, CO 80104

Ricky and all of the technicians are well trained and profoundly knowledgeable. The benefit of having a contract is not only semi annual check ups of the equipment, but the guarantee of a 24 hour response time.
Debbie - Castle Rock, CO 80109

Colt was very experienced and was able to communicate everything he saw and was going to remedy during the inspection. He obviously knows what he’s doing and I’m very grateful he was so thorough. Additionally, Muke was in learning mode and but he made me feel comfortable and at ease . With his knowledge. They were both personable and knowledge about what they were sent here to do. They were s great team and I would. Definitely recommend yhem to someone else!

Again Nytech comes through with flying colors. Ricky and Mike came for annual winter service appointment. Change the filters, check to make sure everything is working well and even checked my water heater. Both guys were nice, clean and focused on making things right. Great service! the the 9 years we have been with Nytech we have never been disappointed with the service or their people!

Nytech is an incredible company with integrity. Long story short, we had another company come out (Patriot Pro's) and they sold us a story that we need either a VERY expensive A/C repair or a replacement unit to the tune of thousands of dollars. When Nytech came in to give a second opinion, not only did they give us an option for a much more affordable repair but they gave us reassurance that the fix would last many years (Patriot Pro's said the fix would only last a few weeks and we should just buy a whole new unit). We were convinced that we needed to spend thousands to get our A/C up and running and Nytech could have taken us for that. Instead their knowledgeable and helpful tech, Colt, gave us the true story and said he could fix it for just around $200. What a relief to get news like that when you first thought you'd be out several thousand! I appreciate Colt's honesty and his thorough inspection of the situation. A/C works great and i feel confident that Nytech will stand by their work. We will definitely use Nytech's services in the future!

My AC unit went out during a pretty hot week in August. I called after work and was offered help immediately. I opted to wait until the first available daytime appointment, but I appreciated that I had a choice. Benji arrived as scheduled and was extremely thorough. I never felt like he was rushing or anxious to get going. He spent a lot of time going over my AC system and helping me figure out the best solution for my home. There are just some things I don't care to be an expert on, but I don't want to feel like my ignorance is being used against me either. Benji answered all my questions (in laymen's terms) and established that he really knew what he was doing. I definitely feel better having a reliable company to call in the future and I will certainly be using Nytech to maintain my HVAC system on an ongoing basis.

The installers were on time and very courteous. The work was completed ahead of schedule. Everything went very smoothly and I am very happy with the work. The only downside was nobody told me an electrician would need to come by to replace a circuit breaker. When I returned the call to the electrician, I didn't know who he was or how he got my number. None of that went very well and I still don't know if a new circuit breaker was installed.
