Your home's air conditioning system needs maintenance at least once per year. The same goes for your heating system. Even though regular check-ins and cleanings throughout the year are always a good idea to make sure your system is operating properly, a once-yearly air conditioner service appointment is always required.

An HVAC system will typically last 10 to 20 years. Regular maintenance is essential to extending the lifespan of your HVAC systems more than any other factor.

What does routine upkeep entail? The following maintenance advice is applicable to heat pumps, boilers, and furnaces:

• Regular filter replacement
• arranging for yearly or seasonal tune-ups
• Debris removal and cleaning of external components
• inspecting and changing the refrigerant when necessary

It is doubtful that your unit will last 30 years before it needs to be replaced. Alternatively, if you maintain your system regularly and use it properly, your chances of keeping the same unit for about 15-20 years are highly probable.
