Mario Marron came by today to repair my heating unit. He was prompt, on time and very professional. He explained the problem, the repair, did the work and we are now happy senior citizens with heat again! Mario is knowledgeable found the problem right away, fixed it and cleaned up afterward. A very pleasant and skilled young man who I would recommend him without hesitation. I would also like to give a thumbs up to Jennifer and Mary from Kaiser who I called for service. They were both extremely polite, addressed my concerns, scheduled service and made my morning. Great customer service.

He took time to take care of the repairing, no rush and kept my place clean. Good to know that he has a college degree in our local college & has many years of experience in air cond repairing. I am very please that I found Kaiser. They have great employees.

Noel is awesome! He is incredibly thorough and detail oriented. He explains the problem and helps find the right solution to fit your needs. I asked for a phone call prior to his arrival and he didn't disappoint. As a loyal maintenance customer of 15 years, I only wish my repairs were handled in a more timely manner from Kaiser Air.
