Geraldo was so prompt in responding to our call. The temperature in my unit had been steadily dropping. Fortunately, we only needed a new filter. Geraldo tested the temperature of the air coming out of one of the vents, and everything was good. We are once again enjoying the warmth. You can take pride in having such a capable technician like Geraldo. Thank you!!!

One Nation Heating and Air Lllc. did an excellentjob servicing my heating unit after we just purchased our home. They discovered the neglect of the the system and completed a thorough cleaning to ensure proper operation of the system. After conducting the cleaning, it was discovered that the mother board required replacing. He gave me a huge discount on the cleaning to ensure that the mother board would be repaired

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.

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.
