1. HVAC Systems

HVAC systems—Heating, Ventilation, and Air Conditioning—keep indoor spaces comfortable and healthy by controlling temperature, airflow, and humidity. As a Maintenance Assistant, you’ll run routine checks, troubleshoot issues, and keep components clean and efficient so systems run steady and costs stay reasonable.

Why It's Important

HVAC performance protects occupant comfort, indoor air quality, and building assets. Stable temperatures and proper humidity control reduce wear on equipment and prevent moisture and mold troubles.

How to Improve HVAC Systems Skills

Boost HVAC reliability and efficiency with these sharp moves:

  1. Routine care: Replace filters on schedule, clean coils and condensate lines, check belts, verify refrigerant levels, and inspect for leaks.

  2. Tight ducts, proper insulation: Seal duct leaks and insulate runs in unconditioned spaces to stop energy drift.

  3. Smart controls: Use programmable or smart thermostats and set realistic schedules and setbacks for off-hours.

  4. Right airflow: Keep supply and return vents unobstructed; confirm fan settings and damper positions match design.

  5. Efficient equipment: When replacing systems, select high-efficiency models and check current SEER2 ratings (updated standard) rather than legacy SEER only.

Small tweaks stack up—lower energy, longer life, fewer surprise callouts.
