Gerardo at One Nation did a great job with my washer hookup installation project. They offered a reasonable price, great communication, and quick service. I would use One Nation again for my plumbing & heating needs.

It was great to work with Gerardo at One Nation. He responded almost immediately when I had an emergency plumbing situation on a weekend. He proved himself to be a man of high integrity in a business world that is certainly lacking that type of trust. I will reach out to him for any future plumbing needs I have.

Details: Yes, repair is urgent • Only one drain has issues • Clogging • Leaking (problem area known) • House

I would give Gerardo a TEN-STAR rating if that were possible! I was thoroughly impressed with his professionalism, effective communication, prompt response time, attention to detail, and desire to find the BEST solution. He showed up on time and was a pleasure to do business with. One Nation Heating & Air replaced my mother's furnace, which was over 30 years old and was failing and making a terrible noise while the blower was activated. I appreciated his follow-up and the care he took to explain things to my mom. Gerardo presented good, better, and best options and offered fair pricing for all these quotes. Please don't hesitate to call One Nation Heating & Air for your next furnace and air conditioning needs! You will appreciate how he does business!

Details: Furnace • Unusual noises from inside • Routine maintenance • Single-level building

After discovering that two toilets and showers were backing up, “One Nation Heat/plumbing” was at my house working on the issue in about 2 hours. Had it fixed in another two hours, which involved going under my house in fairly inhospitable conditions. He double checked that the problem was resolved and we tried overwhelming the pipes with water just to make sure we couldn’t cause it to happen again, but everything works great. I’d use this company again for plumbing and may give them a call for boiler work too.

Details: Yes, repair is urgent • No, the building is not currently flooded • Drain issues • Shower or bathtub • Toilet • House

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.
