Thermostat Replacement in Las Vegas, NV 89129

“I saw an A-1 truck in front of my neighbors house one day, so the next time I saw her outside getting the mail I asked how they liked their service . Since we still had the original thermostats that were installed when the house was built, I knew they were on their last leg and needed to be replaced, it’s just not one of those things that’s ever on the top of my “to-do list”. Can you blame me? I had never heard of The Nest before, but I am HUGE on recycling and conserving energy in any way possible and am kicking myself for not doing this sooner! What a silly little thing to be such a life changer but it is! The Nest has an app so I can change our thermostat remotely from anywhere in the world (my new excuse to go travel)! It also shows me my peek energy usage and savings so I’m much more aware. Look out NV Energy bill, I’m on to you!”
