Maintenance is so vital to the longevity of your air conditioning and heating system. When a repair is done it will only last as long as you maintain it. Could you imagine having your car breakdown due to not changing the oil and then not maintaining it after it was repaired? It would not make any sense to do so. The same applies to when an air conditioning repair is performed on your air conditioning system. You must maintain it to maximize and prolong the life of the repair and also the air conditioning system.
