Rod Miller has an incredible team! We had them install a new unit at the house and because of the seamless experience we now have a service contract that will ensure it is well taken care from year to year. Can't speak enough about how knowledgeable their techs were.

Last night as we head into one of the hottest days of the year, we realized that our A/C had stopped working. First thing this morning I called and they said they could send someone out this afternoon. Then they got back in touch, told me something had opened up and someone came right over. The problem was affordably fixed within an hour and the tech seemed polite and knowledgeable. Will be calling them again if we need someone!

Interior HVAC system had leaked water inside the unit, and onto the floor, accompanied with soaking wet fiberglass insulation inside the lower portion The leak was taken care. The service person began to pack up to depart, with water remaining on the floor from his efforts, and I asked would he remove the soaking wet insulation, and pointed to same on the interior floor of unit and left wall of the unit. He removed about 80% of the floor wet insulation, and removed none of the interior wall wet insulation. He stated that was the best he could do. He left the insulation debris on the floor with

We were not having any problems with our AC - it worked perfectly through 90 degree temps in May. We scheduled Rod Miller for a Spring Inspection on June 2nd to make sure everything looked good for the summer. Their tech told us the only thing we needed was to have the drain from our unit unclogged, which we did. He checked the refrigerant, but said none was needed. Within days of this visit, our AC could not maintain the temp set on our thermostat. It was constantly running several degrees warmer than the setting. We called Rod Miller back and explained the problem. They sent a different tech

Several years ago I responded to an ad advertising special price on first time online users. Set up an appointment guy came, took forever to diagnose the problem. Found him sitting up on the roof smoking a cigarette. When he finally finished and gave me the bill twice as much as the advertised price. When I questioned him he gave me some BS about it Being more complicated. I didn't want to take the time or energy to argue with him so I just paid him and let him go on his way. Later expressed my displeasure to the company, but nothing was done. Later ask him to stop soliciting me with your

Dude in one of their trucks just dumped five bottles of urine in succession on a residential street in broad daylight. Not a good look, and a public health hazard to boot.
