I've read past threads for recommendations and Carrier and Trane seem to come the most highly recommended.
Background - Condo built 15 years ago, original heat pump. Geothermal/gas/etc. not an option.
I had the existing unit checked out and serviced last fall and this spring. Both times I was told the unit is on its last leg and could "blow the coils" at any time. I would like to avoid having to replace the unit in July when it's over 100 degrees here, and have to pay a premium service call. I met with a sales rep and was quoted replcement cost for heat pump and air handler at $5000 to $9000. I have spoken with neighbors who have had units replaced at a cost of anywhere from $2500 to $4500. I know the higher efficiecy rating, the higher the price. In the $9000 range all exterior components are coated with a material that protects from corrosion. I live on a marsh so salt air is a factor.
What should I resonably expect to pay for a unit that will heat/cool an 1100 square foot space? I do live on the top floor and get a good bit of direct sun for the majority of the day. I don't plan on staying in the condo for more than 5 years or so, but at that time will probably rent it out, so I'm not looking for an easy, temporary fix.
