Very happy with AC maintenance services provided by John Park representing Mersey Heating and Cooling. John was very courteous. He was running a bit late however called earlier to keep us informed. He advised us of his action plan for maintenance and once competed, confirmed all that was completed. He also shut-off the humidifier and replaced the filter without any prompt from us. . I am pleased with John’s professionalism and will recommend him / Mersey for HVAC needs.

Edit 2024: Following up on last years heating installation, Miguel D., your HVAC Service Tech, did a thorough inspection job. He found faults and did appropriate corrections. I'd like to see more techs like him for future service calls. I'm very pleased with the service.Arian and Adam plus Clins did a great job installing my Heating system. They explained everything to me and they cleaned up afterwards finishing the install. Great job Mersey Team.
