Dor Mar always does a great job. Preston was awesome. He helped explain the routine maintenance for our tankless water heaters while he did the work. He also double-checked out radon system as a courtesy.

I request Dave Atha for as many visits from Dor Mar as I can. He is terrific. He explains what he is doing, very thorough, thoughtful, friendly and helpful. You couldn’t have a better technician to work with.

During the recent maintenance visit, we conducted a thorough evaluation of the air conditioning system. We initiated the session by inquiring about any specific concerns the customer might have had. The condition of the furnace filter and evaporator coil was assessed, and we recorded the blower amp draw. We also ensured proper airflow by inspecting the cleanliness of the condenser coil outside. Additionally, we examined the electrical components of the condenser for any signs of burnt or loose wires and verified the microfarad readings on the capacitor. Finally, we confirmed that the refrigerant pressures were within the correct range to guarantee optimal system performance.
