Gerardo with One Nation was excellent! The process of replacing my water heater seemed daunting, with high quotes and the uncertainty of if I was being ripped off. Stumbling upon One Nation was a breath of fresh air. He did great work, was very responsive/professional and above all gave a fair honest price. I could not recommend them higher and they will be my go to for all future work.

Details: Yes, the location has an existing heater • Gas tank (standard) • I already purchased the water heater • House

I’m happy to give Gerardo a 5 star rating. I have a small 1948 house with a crawl space like a lot of people in Denver. In December 2024 I was still trying to sleep comfortably with a space heater and extra blankets because my furnace was poorly situated in the crawlspace and did not provide me with adequate heat in the freezing cold night. Then I got lucky: I found Gerardo on Thumbtack. He is a friendly young man who explained what was going on and how he could fix my furnace. He and his crew worked for an entire day and a part of the night to replace my crawlspace furnace so that it now hums quietly and efficiently. While he worked and when he was finished, Gerardo explained to me what was going on under the floors, and that he offered three choices for solving the problems that I was living with, and that the changes he was making were going to make a big difference. Gerardo and his crew literally built me a new furnace with air-conditioning and removed the wreckage of two older furnaces in the crawlspace as well. The thermostat now works with precision and allows me to control the temperature to my needs from my cell phone. I hate to sound like I’m selling something, but it is certainly worth your time to get to know Gerardo and find out how he can help you. I highly recommend him.

Details: Furnace • No heat • Not enough heat • Single-level building • House

I don’t think I could’ve found a better HVAC company to replace my water heater. These guys were more than just professional, they were extremely personable as well. I really enjoyed working with them, knowing that I was in good hands. I also know now that if I have heating or plumbing or AC problems in the future, I know where to go. I highly recommend One Nation Heating and Air.

FAQs

  • What is your typical process for working with a new customer?

    As the homeowner you are the boss. The technician will provide you with various options but at the end you call the shot.

  • Describe a recent project you are fond of. How long did it take?

    A roofing company replacing an old beat down roof needed One Nation to remove and reinstall a 3yr old swampcooler. We did just that and the new positioning looks spectacular!

  • What advice would you give a customer looking to hire a provider in your area of work?

    It's simple licensing, honesty and quality. A company that will go the extra mile for your needs and treat your home better then their's. In other words a company that prides in providing 100% satisfaction to their customers.
