Hello I am new to this and could use some guidance. I apologize in advance if this post is too long, but just want to provide as much information as possible.

Current system, dwelling and location

Location: Louisville, KY

Dwelling: Condominium around 1,500 SQ FT (2nd floor - top floor so my duct work is in the attic)

System: Split system

- Outside AC part is a York (model # H1DB024S06A) it original form when these condo were built (so over 20 years old)

- Inside unit is an Aqua Therm (model # 24VAQ3) it also is original. This is a heating system that draws water form my hot water heater through coils with a blower to heat

my home.

Situation:

I have been in my condo for 4 years. I have had AC unit serviced every year. All has been good by the company that has done this yearly service with the exception of these last 2 years they have had to add about 2 lbs of Freon each year. So I know I do have leak and probably not much time lift with this unit. That being said the last time the serviced my unit was in May of this year. As I mentioned previously at that time the system checked out good, but they added 2 lbs of Freon. The temperature has been increasing here in Louisville, KY, but even on days to where the high temperature outside would only maybe get to like 88 I could not get my AC system to cool my home below 80 degrees. It would just run for hours. I never recall that being the case in past years.

I have a second company come out to look at my unit just 2 weeks ago. They checked Freon levels and he stated it read 40 and the Freon is fine. I explained situation to where it would run for hours and not get below 80. A comment was made stating "yeah it is going to run all day unit eventually at night it will coll done enough to where it will shut off". To me that is not a sufficient answer. I know I have a 20 year old plus unit that is probably not that efficient, but if it only the in mid 80's I believe I should be able to coll my place below 80 degrees without the unit having to run all day. They told me to check and make sure the fan is blowing and the there is condensation on the coil coming out of the unit and that it is not freezing up. I have checked both of these. The fan is running fine and there is no freezing.

Again I know I have a 20+ year old unit and I am probably in need a a new unit, but I still can't help to think that something is not right that it will not cool below 80 when I previous years I know it has been able to. Also I was just not happy with the last response of "run all day and eventually it will get to temperature at night" That is not how an AC system is supposed to work.

Any thoughts questions or suggestions?

Thank you,
