High Energy Bills
StandardUnexpectedly high utility costs from heating or cooling operation.
High energy bills have many potential causes. Start by comparing usage to previous years and checking utility rates. Then address maintenance items like filters. Persistent high bills often indicate equipment problems, duct issues, or home envelope deficiencies. Upgrading to high-efficiency equipment may pay for itself through energy savings.

Frequently Asked Questions
How much can dirty filters affect energy costs?
Significantly. Restricted airflow makes systems work harder, increasing energy use 5-15%. Severely clogged filters can freeze coils or overheat furnaces, causing even greater inefficiency.
Should I replace my old system to save energy?
Potentially. Systems over 15 years old are much less efficient than modern equipment. Upgrading from SEER 10 to SEER 18 can cut cooling costs nearly in half. Efficiency gains pay back over time.
Do duct leaks really matter that much?
Yes. Leaky ducts can waste 20-30% of conditioned air. In unconditioned spaces like attics, this air is completely lost. Sealing ducts is one of the most cost-effective efficiency improvements.
