The answer to 'difference between preventive maintenance and' is that preventive maintenance is proactive, regularly scheduled maintenance to keep your HVAC system running efficiently, while reactive maintenance is performed only when something breaks or malfunctions. Preventive maintenance typically includes tasks like cleaning, inspecting, and tuning up your HVAC equipment to prevent larger, more expensive problems down the road. In contrast, reactive maintenance is done on an as-needed basis to fix a specific issue that has already occurred.
Preventive maintenance is generally more cost-effective in the long run, as it helps extend the lifespan of your HVAC system and prevents unexpected breakdowns. It also ensures your system is operating at peak efficiency, which can lead to lower energy bills. Reactive maintenance, on the other hand, is often more expensive since it involves emergency service calls and potentially replacing failed components.
