I highly recommend Johnston Cooling & Heating ! Kaleb, the service technician who responded to my call was professional , super courteous & totally knowledgeable in addressing the issues with my 50+ year old Honeywell boiler unit! Thanks to Johnston C&H I have total confidence in the performance of my furnace for heat this winter and will certainly be calling them to schedule maintenance service in the near future. Good Job! Kaleb and the Johnston C & H team!
