I had them come out to do a tune up inspection. They were reasonably priced and did a good job explaining what issues I had.

Reviews
Quick response. Fair price. No upselling bs. Turned around next day. Highly recommended.
Tech showed up on time. Got my heater going within minutes. Very knowledgeable and trustworthy. Thank you for making what could have been a very pricy problem, into a small affordable fix.
We had a furnace in our rental property whose pilot light wouldn’t light despite troubleshooting efforts. One contractor got it to light & turn on, & we were told that we would need to replace the pressure switch & ignition control module. Gerardo from One Nation Heating & Air LLC came out for a free estimate & discovered a CO leak that was coming through the heat vents (something that was NOT caught by the 1st contractor). Gerardo informed us that our furnace would need to be replaced & proceeded to provide estimates of all the furnace options we had, answering any & all questions we had about any particular furnace & freely providing his own recommendations based on his knowledge & experience. Once we made our decision, Gerardo quickly & efficiently acquired the furnace we chose & installed it the next day! We are grateful for Gerardo’s expertise, knowledge, experience, professionalism, work ethic, & integrity. It’s hard to find trustworthy contractors these days, but we felt well taken care of by Gerardo. I highly recommend Gerardo with One Nation Heating & Air LLC.
One Nation installed a mini-split unit for me. They were super professional, very clean and ensured everything worked well before leaving. They are also very flexible to work with my schedule as well. 10/10 would recommend.
Gerardo and his team were awesome. They installed 3 ceiling cassette mini split units and one wall unit. They worked really hard to get the job done in a tight timeline. We really love the units and wish we would have done it years ago.
They were knowledgeable and timely. They did a great job
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!
Very responsive and offered to come the next morning to service the A/C unit.
Gerardo was able to quickly get out and get me back up and running. He also came back and serviced the units, and said he would let me know if they found anything else after they got in there. He said everything was good, just needed to be cleaned which is what he had done. He didn't try to tell me I needed to do a bunch of extra stuff.
This is the best experience I’ve had for work done on my houses by far. Punctual, respectful, worked hard and delivered a great overall product. I couldn’t recommend this group enough.
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.
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 and his crew were a lifesaver for my home. About a month ago, my husband had a health crisis and simultaneously, our ancient furnace broke and our water heater leaked. Our previous HVAC technician wasn’t responding, so I had to hunt for a new company from the hospital. Fortunately, One Nation had tremendously positive reviews, which made it easy to choose. Gerardo responded immediately, came out to assess same day, and had a few quotes for us that evening. We ended up replacing the furnace and AC for high efficiency models with his team; they were quick, thorough, polite and tidy. The work is immaculate. They also repaired our water heater and added the expansion tank that our last tech failed to do. And the price was highly reasonable and fair. Gerardo gave so much time and energy to us when we needed it most. He patiently walked through the model options and pros and cons of individual services. His level of devotion and professionalism feels truly unparalleled these days. I could not recommend him more, and am grateful we were in his hands during that stressful time.
Great experience with quality products delivered timely and efficiently.
Prompt and experienced, not over-salesy, recommended a solution that was perfect for the property.
Needed quick repair and they were there, thanks one nation!
I highly recommend!! I found All Nation on thumbtack and got a call within 5min. He came out same day and did a deep cleaning got my A/C tuned up and blowing cool again in no time!!
They were on time and very upfront about what was wrong as well as options for repair.
We had a great experience with One Nation Heating and Air for a new heat pump installation. This local business was super knowledgeable and took the time to answer all of our questions, helping us find the best option for our needs. They were professional throughout the entire process and did a meticulous cleanup when finished. Highly recommend them for their expertise and outstanding customer service.
