Which heat pump brand is best for mostly cooling?
We have to replace our 2.5 ton heat pump after 6 years because the freon leaked out, black sludge (oil) formed in lines, compressor and coils ruined. We had the compressor replaced under warranty but sludge was still in lines even after using R-11 flush and new compressor was ruined. Two HVAC contracgtors have told us that we need to replace everything. Of course, both contractors only recommend replacing with the brands that they sell. One sells Bryant and the other Heil/Tempstar. I want to have a few other contractors selling other brands come out for a quote. Is there a particular brand of heat pump that is better for cooling than others? We live in coastal South Carolina and rarely use the heat on the upstairs unit. Which brands are currently offering the best warranty? I know it is all about who installs the unit because most of the internal parts are the same, but there are 100s of HVAC contractors in my area and have not been lucky with getting good recommendations locally. Thank you for your help.
