How often does my furnace need maintenance?

Your furnace is at the core of your HVAC system. We recommend having your furnace and HVAC system serviced every year to ensure proper operation all year long. For most homeowners, this requires a furnace service in the fall and an AC service in the spring. This ensures your heating and cooling units are properly cleaned and maintained before running each season.

How do I know if my Heating or Air Condition is working properly?

While every HVAC system is different, if you notice a reduction in efficiency such as luke warm air, reduced airflow, or even increasing utility bills with no change in your usage, this may be a sign that your system needs maintenance. If you hear irregular noises, notice a water leak, or see frozen coils, we recommend calling us immediately at (815) 728-7401.
