A service tech said he could test our unit (16 year old Carrier, single package, all electric, heat pump a/c) for $X to see if he could locate leaks. If so, he would charge $X to change capacitors, clean out debris, dirt and install some type of gunk into the system that would seal up any leaks in the compressor or the other parts of the heat pump. This sounds fishy and expensive.
He gave us a quote for installation of a 3 ton trane (using an American Standard model number) for a 1250 sq foot home of $X but he couldn't guarantee if the unit could pass California's 15% efficiency standards.
We have gotton several quotes so far and they are really strange and no one except the Trane dealer has seemed entirely honoest.
Any advice. We paid $X to have our system filled with freon 2 weeks ago and were told that if it stopped running that we needed to replace the system.
Also Any advice on the new vs old coolant on new installation?
