Heater maintenance includes a thorough inspection of all components, a detailed cleaning of all surfaces, and a complete system recalibration. All shifted components and parts are moved back to their original location. Moving parts are lubricated, and loose screws and bolts are discovered and tightened. HVAC maintenance is fairly straightforward but extremely important for the system. Kalins Indoor Comfort is prepared to service all HVAC types and will have all the parts and tools and the experienced furnace contractors needed to get the job done in one visit.
