As with most things, the better care you take of your heating and air conditioning unit, the better it will perform and the longer it will last. If you neglect your system, then it could be underperforming, and this can really show on your energy bill.
There are simple things you can do to help take care of your system like changing your air filters. This keeps dust and dirt from getting into the system and clogging it up. However, through your system’s months and years of service, it still can collect dust. This dirt buildup reduces airflow through your system which makes it have to run longer to heat or cool your house. If your system is outside, it can also pick up debris from items like your dryer vents, leaves and lawn mower dust.
It’s important to get your system cleaned and tuned up at least once a year to keep it running safely and efficiently. Read this report about “The Cost of Neglecting Your Home Comfort System” to see more about the hidden costs of putting off maintenance for your home comfort system.
