Jan Garrido says, "Warm Welcome is truly and understatement when it comes to this company! Our water heater went out over a month ago, so we have not had hot water, I have health issues and just didnt know where to turn to as this was a very expensive repair that we were not prepared for. Ty and his wife reached out to me and offered to Gift us a Water Heater. Im in tears as I write this review, to know that there are still good people in this world with compassion and kindness that Ty showed to our Family. He also came and personally installed our water heater and did a wonderful job, which I thought was so kind of him to offer to do it himself. He went above and beyond to take good care of us! Ty and Warm Welcome, We will never be able to express how grateful we are! Thank you so very much with all our hearts! We highly recommend this company, they are truly incredible and every staff member I came into contact with! You will not regret it! Thanks again Ty!!"See more

Kristin P. says, "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."See more

Alma Gandara says, "My experience with choosing True Flow Heating and Air has put ease of mind with our new HVAC replacement. This new unit is so quiet and has been working perfectly well. I can assure to say I feel safe now. The Technician was very knowledgeable at explaining everything that needed to be done and how long it would take for the installation process. What impressed me, was that I had everything installed within that same week! Just in time for colder weather. They were here on time and the clean up was top notch. I would highly recommend their company. Also wanted to add they did do a follow up appointment to make sure everything was installed and working correctly."See more

Nor Shkoukani says, "After dealing with two other HVAC companies that recommended expensive repairs and even a new furnace, Brian and Juan took the time to properly diagnose and fix the actual problem. They were quick to respond, honest, knowledgeable, and very reasonable. They earned our trust and have definitely won our business. We highly recommend them!"See more

This was a really negative experience. I have an old swamp cooler that I wanted to get functional - I knew the fan worked fine but had never hooked up water. Yuriy first tried to upsell me on replacing it with a several thousand dollar new air conditioning system. When I said no to that he pointed out that the pads needed replacing and that it was rusty and might leak. He didn’t explain to me how it functioned or what might be done to address the leaks, and he never stayed to see how much it leaked before leaving, he just shut the water off. When I turned the water on and discovered the leak he agreed to come back and look at it and did what was clearly going to be an ineffective repair, as well as replacing the float valve - if this needed replacing why didn’t he do it the first time? The leak got much worse. I ended up patching the leak myself, as well as having to reinstall the incorrectly installed float valve so that it wouldn’t constantly overflow. When I called to ask for a partial refund he gave me $50 back, so I essentially paid $300 to do the repair myself.
