Are there any HVAC experts on here willing to chime in on some info we got from a salesman a few weeks ago?
We currently have a 12 year old AC/Furnace system that was put in by the builder. Its been freezing up and giving us sporadic trouble over the last few years, so we called a company to come out and price a new system. It was very odd...for a salesman he wasn't interested in pushing his top of the line products, and instead steered us towards middle to lower line models. Two things he said didn't really make sense to me and I'm wondering if y'all have any opinions/insights on the matter.
1) He said that the lower tier units in the 12-13 seer range for our home (2k sq foot two story slab) were more economical than the super high end models in the 19-21 seer range with all the bells and whistles. Said they could and would operate at higher efficiencies than they were officially rated.
2) He also said that with the eco-friendly craptastic refrigerants they have to use nowadays, its difficult for an AC unit to consistently cool a home to more than 20 degrees cooler than the ambient outside air temp. So...if its 95 outside, it will be hard for the unit to cool inside lower than 75. I remember that not being the case on those 100 degree days in NC. But that was also in a house built 20 years ago.
Thoughts?
