When I got my brand new central heating and air conditioning system I could not believe how perfect it was! I guess before this I never had a decent working heat and a/c unit. Because with this new heating and cooling system I can tell you that the air flow is just right and the thermostat actually can be set at the exact temperature you want it to be at! With my old heating and air conditioning unit I had to set the thermostat higher or lower than it needed to be depending on if it was heat or a/c. Because it just didn’t give off enough power. But no more! Everything is perfect now with my heating and air conditioning. Well, it has to be. Because I spent so much money on this HVAC unit. I made sure to get the most brand new, up to date, great SEER rating and very pricey heating and cooling unit. And believe me, it has paid off very well. Not to mention, with the great SEER rating I am actually saving more money on my monthly electric bills as well. I did not get that in the past. My old heat and a/c system had a really bad SEER rating I found out later on. I was not familiar with SEER ratings at the time I bought the old heating and air conditioning system. This was because I was young and just got my first home. I knew nothing about heat and a/c. I am glad I now have the most perfect HVAC unit!
