“Last fall Old Coast installed a new heat pump in our HVAC system. Service was professional and timely.
We had them come this summer for a maintenance call. John K. the tech arrived on time and during the service noticed a small issue with the HVAC and fixed it. He took the time to explain what he did complete with photos. Thank you John K. and Old Coast for keeping our HVAC operating at peak performance. Love the cool air on a hot day!”
