I called another AC company to troubleshoot an AC unit blowing hot air. The tech explained that the compressor needed to be replaced for close to $3,000 but that I should seriously considering replacing the 6 year AC system for a heck of a lot more. I called Semper Fidelis for a second opinion and Jonny explained that the condenser was fine and that I only needed to replace the capacitor for a tenth of the cost of the compressor. Very responsive, honest and competent in true Marine tradition!
