Exceptional service experience with Miko. Very knowledgeable, thorough inspected and maintained our multiple HVAC units, provided guidance on maintenance and advice on unit status. Explained all work clearly and thoroughly. Quickly got our units back to optimal operation when a couple of issues were identified. Overall fantastic service and customer experience! Thanks Miko!

I love this company! They put out real effort to get you scheduled for your routine maintenance, allowing flexibility to request either morning or afternoon service. Their technicians are friendly, polite and communicative., esp the one who came today! Nasar Barenji. He came early, was super nice, exceptionally competent and emphasized the critically important repair another one of McCullough’s routinely excellent technicians had recommended a year ago at my annual summer inspection that I could not afford at the time to authorize. They are all doing their best to help me extend the life of my aged HVAC system.
