Key warning signs include a yellow or flickering burner flame (instead of steady blue), excessive condensation on windows, sooty stains around the appliance, and a persistent, stuffy smell. Most importantly, if household members experience flu-like symptoms like headaches, dizziness, or nausea that improve when leaving the house, evacuate immediately and call for help. Greenleaf HVAC provides comprehensive furnace safety inspections to detect and resolve these risks before they become an emergency.

Yes, reduced cooling capacity is a common symptom of a refrigerant leak. This is a serious issue for two main reasons: First, leaking refrigerant is harmful to the environment. Second, and more immediately for your home, low refrigerant makes your AC unit work much harder, leading to higher energy bills, potential freeze-ups, and compressor failure—a very costly repair. Our technicians use specialized tools to accurately locate and seal leaks, then recharge your system to the manufacturer's precise specifications, restoring efficiency and protecting your investment.

We recommend professional maintenance twice a year: once in the fall for your heating system and once in the spring for your cooling system. This seasonal schedule is crucial for our local climate. The fall tune-up ensures your furnace is burning cleanly and safely to prevent carbon monoxide risks before winter. The spring check-up prepares your AC for summer, checking for refrigerant leaks and ensuring optimal efficiency. This proactive care prevents breakdowns, extends system life, and keeps your family safe and comfortable all year.
