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.
I worked with Gerardo to replace a failing A/C unit, and I had a great experience from start to finish. Gerardo came out to provide an estimate and put together an excellent system with a Bosch furnace, A/C unit, and heat pump at a very competitive price. He took the time to thoroughly explain the system, answer all of my questions, and make sure I understood exactly what I was getting.
He was also able to schedule the installation quickly. His team, Jesus and Uriel, showed up as scheduled, installed and configured everything, and did a great job cleaning up afterward. They even went above and beyond by fixing two loose ducts in the house.
I’m extremely satisfied with the quality of their work and the entire experience. I’ll definitely be calling Gerardo and his team for any future HVAC needs. I highly recommend them to anyone looking for reliable, knowledgeable, and professional HVAC service!

Gerardo and his team were fantastic. They installed an entire HVAC system in our home, including a whole-house humidifier. They cleaned up our existing wiring in the electrical room and hauled all our old equipment away. They took the time to explain the details, and have come back since to clean the filters, help us with getting the air turned on, and overall maintenance. Can’t recommend them enough!

I highly recommend Gerardo and his team for your HVAC needs. They provided fast, reliable service at a very reasonable price.
Gerardo was able to quickly diagnose and fix our HVAC system, and what really stood out was that he honored the original quoted price even though the job ended up requiring additional work.
In my experience, many HVAC companies seem more focused on maximizing the bill, but I genuinely felt that One Nation was different. They were honest, professional, and focused on getting the job done right without trying to take advantage of the customer.
Thank you, Gerardo and the One Nation team, for the excellent service!

We had a great experience with One Nation. Gerardo and his team installed a new furnace and ac system for us. The entire team was professional and so respectful. Gerardo specifically was patient and made sure we were fully comfortable with the install. The products they have are great quality (I did lots of research because I don’t want problems) and the price was fair. Overall, we felt grateful to have found One Nation for our hvac needs. We will recommend and use these them for any future needs. Thank you, Gerardo and team!

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.
