After receiving a call from a Tenant, that the furnace wasn’t working in a rental property. I contacted Keith Heating and Cooling, for the first time. From the very first greeting on the phone, to the call from the Technician advising me that they had finished the job. I couldn’t have asked for a more professional, conscientious and pain free experience. There’s no doubt whom I’ll be calling in the future. Top Notch Company.
