Very happy with choosing Onenation to fix my AC. It wasn't working and I wasn't upsold parts I didn't need. I only needed a deep cleaning to restore proper airflow. They were literally here as soon as I posted the need for service. Very responsive. Will definitely use in the future.

Gerardo was amazing, I called him at 5pm when my AC compressor stopped working. Even though he was on his way to another call he still made it out to my place at 8pm to make sure he could look at my AC during this heatwave. He quickly diagnosed the problem and went above and beyond while fixing it. He was super friendly and helpful the entire time and was more than happy to explain everything he was doing. Will definitely be using him for all HVAC going forward.

Gerardo was great, very responsive. He came out right away and fixed the problem with my A/C condenser. He provided several options to chose from, and was very knowledgeable. I would use One Nation Heating again.

The quickest and best experience I’ve had. The technician, Gerard Lopez, arrived ahead of schedule, effectively evaluated what was going wrong with my AC, and provided really clear advice on how to resolve it without pushing unnecessary services and sales. He was honest and held great integrity even though it didn’t put money in his pocket. That’s real service! Will definitely be coming back to them for any further services needed.

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.
