The air conditioner product life cycle can vary somewhat by brand and specific model. In general, today’s air conditioning units can be expected to last between 10 and 15 years. When you speak with an air conditioning specialist from Advanced HVAC in Ottawa, we’ll let you know more about the specs of the A/C unit(s) you’re looking at and how long they are expected to last. When we speak of the expected lifetime of an air conditioner, that is, of course, assuming proper maintenance and upkeep. While reasonably minimal, there are a few things you can do to keep the A/C unit lasting longer, such as cleaning the coils, changing the air conditioning filter and performing a yearly air conditioning tune-up and maintenance.
