I have never written a review on Homestars before, but feel I need to warn others after the terrible experience we had with Reliance. Our air conditioner broke during one of the hottest weekends this summer. At the recommendation of Reliance, we purchased a new AC unit from them. They also changed our thermostat to a programmable one. After they installed the new AC unit, it never worked properly. It would continuously run for days and never reach the temperature set.
After 5 visits from their technicians claiming that everything is working properly (even though it is clearly not), they all of a sudden recommend that it must be the air handler that now needs replacing (which would likely cost another $2000).
At this point, it is very clear that they do not know what they are doing, and are only trying to make more money off of us. We are fed up (after having to take time off work to be home for all of these visits and making no progress), and say we want to send the AC unit back and get our money back (they have a money-back guarantee).
We hired another company, purchased a new AC unit from them. Long story short, the issue was the thermostat installed by Reliance (not the air handler and whatever else they would have tried to sell us).
Avoid Reliance so you don't have to deal with similar time-consuming hassles and incompetence.
