Review of ETRU Heating, Cooling, and Insulation

gas furnace wouldn't fire up right and he figured it out pretty quick. new gas valve. he also heard a gurgle and figured out water was not draining right as well. all from a small tube. And the gas valve was replaced in no time. very pleased with the service provided to me.


Can't say enough good things




Review of ETRU Heating, Cooling, and Insulation

When my old heating and cooling guy went to a new job, I asked for a recommendation and he gave me Ryan's name. I called and they were very accommodating with my appointment and they showed up exactly when they said they would. My system is 29 years old so I thought I would probably have to buy a new heat pump. Ryan knew exactly what the problem was and he knew my system inside and out. I was in awe of his work! I can't say enough wonderful thing about them. My system was fixed and and it purrs now. So efficient and I still love my Trane heat pump. They gavel top notch service and my bill was shockingly affordable. I wouldn't hesitate to call them again and I'm sure I will. When the time comes to say goodbye to my Trane, I'll call Newcomb Heating and cooling. IAgain, I can't stress enough how happy I am with them.
