Newer systems can probably do with once-yearly maintenance to stay in shape and maintain the warranty. Older systems, depending on their condition, might need twice-yearly tune-ups for optimal performance. Other factors to consider include the age of the system, the usage the system endures, and the condition of the parts inside the system. We recommend that you have one of our expert technicians give your system a tune-up so that we can better recommend a maintenance schedule to keep things running just the way they should. As a rule of thumb, there’s no such thing as too much maintenance, but less than once a year can be costly!
