Heating and Air Conditioning equipment should be serviced at least once a year. The best scenario is to have the heating system checked in the Autumn and the air conditioning checked in the Spring.Oil-fired equipment should definitely be cleaned and serviced annually.eating and Air Conditioning equipment should be serviced at least once a year.

The company sales pitch is the twice a year maintenance is needed for the heating side in the Fall and A/C side in the Spring. Iâm not an expert but two maintenance calls per year on an HVAC system seems excessive. Iâve owned my unit for 6 years. Two of those years I signed up for twice a year maintenance plans. The other 4 years I had the unit serviced once a year. I am conflicted because it seems to me an HVAC system is an all-in-one system, sort of like an all-in-one printer.
