We wanted to thank Gerardo for fixing a corroded pipe on our water heater. We are selling our house and the issue was presented via the inspection report. As chaotic that can be Gerardo was very communicative and prompt throughout this job. Thank you very much!

Gerardo (One Nation) is da man!!!!!! He went out of his way to come over after the Sabbath to give my Aunt a quote to replace a failed water heater. He showed up Monday morning at our desigantaed time and went straight to work. He made recommendations to improve shortfalls of the previous installation, and was a fraction of the cost of another company (Br--thers) who quoted an 81yo lady ($4700) to replace the water. The workmanship and professionalism were top notch. I plan on using them for all future plumbing needs.

When scheduling a HVAC check/service, they were very quick to respond and set up a convenient time in the near future. Showed up on schedule. HVAC was pretty new and didn't need repairs; they didn't try to upsell any unnecessary work. I did have unrelated HW heater work needing to get done; they were able to perform the work immediately. Venting and supply line repairs look great. Friendly and professional.

Details: Furnace • Routine maintenance • Basement • Three-story building • Condo or apartment

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.
