I ran a big corporation in another state for nearly 35 years, and if I learned anything, it is that customer service is what matters most of all. In that state, good customer service was the rule and not the exception. When I moved to Las Vegas, I discovered that good customer service was the exception. Until, I first used Sahara Air Conditioning & Heating. This company always puts their best foot forward. Their employees wear uniforms, and they arrive on time. They wear booties inside the house to protect the floors, and they also wear gloves. Their trucks are clean, and well-marked with the company logos. They bring their own ladders, so they do not have to borrow yours to get up into the attic. And speaking of the attic, they put the attic cover back down correctly so that it closes properly. They are friendly and professional. They give you good detailed invoices, and you can pay them there, or simply call the payment in. All in all, their customer service is probably the best that I have ever seen. We have been extremely happy with them. As far as their work, since we moved here four years ago, they have done routine service on all three of our furnaces, and all three air conditioners. They have replaced one air conditioner and one furnace, and they performed major repairs on another furnace. They have also installed three top of the line air filtration systems. Their work is high quality, and we would give them Five Stars Plus on that, and in fact Five Stars Plus on the entire company! Needless to say, we highly recommend Sahara Air Conditioning & Heating to everyone!
