I have HVAC coverage through Reliance ($20 / mo, hence the cost listed with this review). I reported an issue with the furnace. Reliance sent out Matt, who was attentive and quickly diagnosed the issue. He quickly repaired it and remained absolutely professional throughout. He explained what he was doing and why he was doing it. 30 minutes later I was back up and running. This would have been a 10 star review were it not for the fact that I reported this issue to Reliance a few weeks earlier and they did not appear in the 5-hour window they gave me (I received a call at the 5-hour mark saying they were going to be late, but I could not wait around any longer). That was frustrating -- and I also think that they could take a lesson from a certain cable company who has a much better system for dispatch (i.e., estimating time of arrival, tracking dispatch, etc.).
