Dan Bertrand from Eagle One came to our house and installed a Nest thermostat after we paid an electrician to come in, spend two hours trying to figure out the problem with the end result being he could not get the nest to operate properly. We literally paid for the electrician’s time and that company (Davco) made money off of us to do nothing. We called Dan and he guaranteed he would get this done with very little cost to us. What a saviour as he understands Hvac systems and even guaranteed that we would not need him to come back a second time as the work was done right the first time. Highly recommend his services.
