It’s generally true that the more often you have annual service performed, the more you’re likely to benefit from the service. But even if you’ve neglected to service your furnace for a few years, you can still get in on its benefits by starting regular service now.
- Better furnace efficiency – Your system can only reach, or come near to, manufacturer expectations if it’s clean. In fact, dirt is generally the No. 1 enemy of efficiency, as dirt that rests on components like the motor, air handler or heat exchanger creates friction, causes the system to consume more energy and increases wear and tear.
- Improved comfort – When dirt buildup is left unchecked, it starts to wreak havoc within the system. As efficiency decreases, the furnace’s capacity to generate heat decreases, impacting other components like the air handler’s ability to push heated air into your home. As a result, you may notice that some of the rooms in your home aren’t as comfortable as they used to be, or you just aren’t as warm in your home as you’ve been in the past. But a clean system will operate at peak capacity, and provide optimal home comfort.
- Extended life – A furnace system should generally last around 15 years. However, manufacturers assign a furnace an expected life span under ideal conditions, meaning you must maintain the furnace to achieve those expectations. However, most HVAC experts believe homeowners can extend that life span even further with annual maintenance. In fact, you can generally achieve a longer life span by up to five years, just by investing in a fall furnace tune-up each year.
- Low lifetime costs – The amount that you paid for your furnace does not represent the overall costs related to operating it. Taking operating costs into account gives you a more accurate idea of lifetime costs. And with regular maintenance, you can ensure that you keep lifetime costs low, because a clean, lubricated system wards off wear and tear and component failure, keeping repair costs low — or even non-existent — and energy savings high
