The answer to 'how long will preventive maintenance last' is that with proper HVAC preventive maintenance, you can expect it to last 1-2 years before needing to be performed again. Preventive maintenance typically includes tasks like cleaning the unit, checking refrigerant levels, inspecting electrical components, and replacing air filters. This regular maintenance helps ensure your HVAC system runs efficiently and extends its lifespan.
The exact timeframe can vary depending on factors like the age and condition of your HVAC system, how often it's used, and the environment it's operating in. Homes with pets, high humidity, or lots of dust and pollen may need maintenance more frequently. It's best to follow the manufacturer's recommendations and have a professional HVAC technician perform the maintenance annually or bi-annually.
