• Condensate drain inspection and cleaning for high-efficiency units
• Ductwork and airflow observations to help improve distribution

Why Preventive Maintenance Matters

• Reliability: Catch small problems before they cause a no-heat emergency on a chilly night.
• Efficiency: A clean, tuned system can use less energy, helping lower heating bills.
• Extended equipment life: Less stress on components means a longer service life.
• Warranty support: Many manufacturers recommend routine maintenance to keep warranties in good standing.
• Healthier air: Cleaner components and correct airflow support better indoor air quality — our core mission for a healthier life at home.
