Humidifiers

• Purpose: Add moisture to the air, reducing dryness and improving respiratory health.
• Types: Evaporative, steam, and ultrasonic humidifiers, suitable for different room sizes and moisture requirements.
• Benefits: Relieve dry skin, sore throats, and congestion, and protect wooden furniture and musical instruments from damage.

Dehumidifiers

• Purpose: Remove excess moisture from the air, preventing condensation and mold growth.
• Types: Refrigeration-based, desiccant, and whole-house dehumidifiers, varying in capacity and efficiency.
• Benefits: Improve indoor air quality, reduce humidity-related allergies and asthma, and protect against structural damage.

Air Purifiers

• Purpose: Remove harmful pollutants, allergens, and odours from the air.
• Types: HEPA filters, electrostatic precipitators, charcoal filters, and ultraviolet (UV) purifiers, each with specific filtration capabilities.
• Benefits: Improve indoor air quality, reduce respiratory issues, and create a healthier living environment.

Maintenance and Troubleshooting

Regular maintenance of HVAC parts and accessories is crucial to ensure optimal performance, extend lifespan, and reduce energy consumption. Here are some essential maintenance tips:

• Clean or replace air filters regularly.
