The annual maintenance service usually includes cleaning the air filters, checking the refrigerant level, checking and tightening electrical connections, lubricating moving parts, inspecting the condensate drain, and checking the overall performance of the unit.
If there are any repairs needed during the annual maintenance service, such as replacing worn-out parts or fixing leaks, there will be additional costs involved. The cost of repairs can range from a few hundred dollars to over a thousand dollars, depending on the extent of the repairs needed.
It is important to have annual maintenance performed on your air conditioning unit to ensure that it is functioning efficiently and safely. Regular maintenance can also help extend the lifespan of the unit and prevent more costly repairs down the line.
