Since having our central air installed, it never really cooled our home down. For 3 seasons it remained humid, damp and rather uncomfortable no matter what temp the system was set at. Despite having it serviced many times, the answer was always the same - it was installed properly and it was just our furnace getting too old We were told it was time to replace it. With limited dollars, we decided to get a second opinion. A smaller, independant local company came in and did their magic. Needless to say, from that time on, we finally had a properly functioning & cooled home during the summer months. Seems that Reliance never installed the system properly in the first place. A word of caution - just because a company works with the energy supplier doesn't mean they are always right about everything. When in doubt, get a second opinion before spending money. Bravo to the small business contractor - bigger isn't always better. I can only recall the reps name as Jim.
