This is the first time I ever wrote a review for anyone but I feel Nevada Residential really deserve this. They had my heater fixed within one day and when we called him back on something else, he was there for us. I called Nevada Residential at about 6:00 am expecting to leave a msg but Arthur answered the phone right away. My experience is they are the most trustworthy company I have ever seen, another company quoted me that I need to buy new unit which will cost me about $5,000+, Arthur fixed it for $580. From now on, I don't need to search any longer, Nevada Residential is going to be my go to for heating and cooling.
