My upstairs AC unit wasn't working so I called a large, well known company to come out and look at it. They told me the compressor was broken and both units should be replaced, as they are 12 years old. They quoted me $10-12K for the complete job. I decided to get a 2nd opinion. Jonathan from Cool Masters came out and fixed it in 15 minutes for a total of $271! Turns out the compressor is just fine! Jonathan said I should be able to get another two to three years out of the existing units. He also gave me prices and more options should I choose to replace the units. His prices were much more affordable! Thank you for your honesty and reasonable rates!!! So good to have an honest heating and air company!
