Im looking for some help... Im looking to replace my old gas furnace and A/C with a new, more efficient system. I live in a 3 story townhouse. The bottom level is where the furnace is and it used to be a basement that we have finished off. That level stays relatively cool throughout the year no matter what the temperature is. Last year during the summer my A/C would not cool the second or third level below 75 degrees. This year when we started it we couldn't get it below 80 degrees and it was only 85 degrees outside.
I had a local company come out to quote me on a new system and I thought it was ridiculous in price... They wanted over $ for a Goodman 13 SEER A/C and 95% furnace without the variable speed fan, which I would like to have.
Basically Im looking for some advice on what size furnace and A/C I should be looking at, Im thinking of doing the project myself or having a tech install. Any feedback will be appreciated.
