I have used Aliso Air on all three of my houses. They have been nothing but proffesional and curtious. Their work is meticulous. I would recommend them to anyone. I don't understand the negative comments above, maybe were written by their competition.

They came out and fixed my furnace that another company told me was shot and wanted $2,000 to replace it! Great price and honest!!!! A++++

I have spent well over $3,000 with this company. Their first technician said the 'fix' would be to just refill the freon. When this solution didn't work, Aliso Air sent out another technician who diagnosed the 'fix' to be the replacement of a coil. The service manager said he would give me a credit from the first repair disaster to be applied towards the coil replacement. He never did and unfortunately, the 'fix' /coil replacement did not work.To no surprise, Aliso Air came back and said (after 2 failed attempts at a 'fix' and me out several thousand dollars), that the final 'fix' would be the installation of a new compressor. I chose to go to someone else who not only did a stellar job, but did it much cheaper than Aliso Air. If you want your air conditioning problems to be fixed - DO NOT use Aliso Air.
