HVAC System Care Guide
System Overview
The HVAC (Heating, Ventilation, and Air Conditioning) system controls indoor temperature, humidity levels, and air circulation within the home.
In warm climates, HVAC systems operate frequently and require regular maintenance to ensure proper airflow, energy efficiency, and equipment longevity.
Proper maintenance of the HVAC system is a routine homeowner responsibility.
Routine Homeowner Maintenance
Homeowners should perform the following maintenance tasks:
• Replace HVAC air filters every 1–3 months
• Inspect the condensate drain line periodically
• Clean the condensate drain line every 6 months
• Keep outdoor condenser units free of debris
• Schedule professional HVAC servicing once per year
Regular maintenance helps maintain system efficiency and indoor air quality.
Common Issues Observed in Homes
The most common HVAC issues typically result from lack of maintenance.
Examples include:
• clogged air filters restricting airflow
• blocked condensate drain lines causing water leaks
• frozen evaporator coils due to airflow restriction
• reduced cooling performance
In humid climates, algae growth inside the condensate drain line may cause water to overflow from the HVAC system.
Routine maintenance helps prevent these conditions.
Cooling System Performance Expectations
Residential air conditioning systems are designed to maintain indoor comfort under typical residential operating conditions.
Under standard design conditions used throughout the United States, residential cooling systems are generally designed to maintain an indoor temperature approximately 18°F to 20°F below the outdoor temperature.
Example:
If the outdoor temperature is 95°F, the system is typically designed to maintain an indoor temperature near 75°F.
During periods of extreme outdoor heat, the HVAC system may operate continuously in order to maintain the desired indoor temperature. Continuous operation during hot weather is normal and does not indicate a system malfunction.
Lowering the thermostat to extremely low settings may place excessive demand on the system and may contribute to evaporator coil freezing, particularly when airflow is restricted.
Frozen evaporator coils may result in:
• reduced cooling performance
• ice accumulation on the indoor unit
• temporary system shutdown
• water leakage when the ice melts
Maintaining reasonable thermostat settings and replacing air filters regularly helps prevent these conditions.
If the system is unable to maintain reasonable cooling performance under normal operating conditions, a licensed HVAC technician should evaluate the system.
Indoor Humidity Control
Florida’s climate includes high humidity levels for much of the year. Proper humidity control is essential for maintaining indoor comfort and preventing moisture-related issues.
Air conditioning systems help remove moisture from indoor air during normal operation. For effective humidity control, homeowners should avoid turning the HVAC system off for extended periods, especially during warm seasons.
Recommended indoor humidity levels are typically between 45% and 60% relative humidity.
Allowing humidity levels to remain elevated for extended periods may contribute to:
• condensation on surfaces
• musty odors
• potential mold growth
• flooring movement or expansion
Maintaining regular HVAC operation and replacing filters regularly helps ensure effective humidity management.
When to Contact a Professional
Homeowners should contact a licensed HVAC technician if:
• the system is not cooling properly
• water is leaking near the indoor unit
• unusual noises occur during operation
