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.

I had “furnace tune up” that cost 125$, that was on sale for $29 from ARS rescue rooters. They didn’t tune anything up - just produced a quote for 4500$ worth of work and said I should think about getting it replaced. I had One Nation come out and not only did they find the furnace in good condition, they did a cleaning of the fan and burners for 375$ (ARS quoted 1000$ to clean those things). I’ll be using them from now on.

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.
