I recently had the Smart Air 1000 AC installed by Reliance. The unit didn't work. A Reliance service person came to fix it. Here is the story.
A sub-contractor hired by Reliance came to install the AC. They did a good job, were friendly and the install went smoothly. The only problem was that the unit didn't work and the guys couldn't fix it. They left right away and passed the problem over to Reliance. A couple of hours later a Reliance serviceman showed up to trouble shoot the the issue. Phil was very professional and inspected the sub-contractors work. He had to return the next day to continue as it was already late. He identified some issues he felt were not up the the companies standards and fixed them right away. Phil found the problem and fixed it easily. He also took the time to help increase the efficiency of my system (furnace, fan, filter) and inform me about the differences between older and newer furnaces, not trying to up-sell.
I recommend Reliance. Service is excellent.
