1. High-Efficiency Air Filters (HEPA and MERV 13+)

Your HVAC’s air filter is your first line of defense. Standard filters trap larger dust particles, but higher-rated filters (like HEPA or MERV 13+) capture much smaller particles—including allergens, smoke, and airborne bacteria.

• Benefit: Reduces allergens and airborne irritants.

• Important: Your HVAC system must be properly sized to handle high-resistance filters without airflow issues.

2. Whole-Home Air Purifiers

Standalone air purifiers are good—but HVAC-integrated air purification systems are better. Technologies like UV-C lights and ionization systems actively kill bacteria, neutralize viruses, and break down VOCs.

• Benefit: Cleaner, healthier air delivered throughout your entire home.

• Popular Options: UV-C light purifiers, Photocatalytic Oxidation (PCO) systems, and Bi-Polar Ionization devices.

3. Humidifiers and Dehumidifiers

Humidity levels aren’t just about comfort—they impact your health too. Dry air can irritate respiratory systems, while excess moisture fosters mold and bacteria growth.

• Benefit: Balanced humidity protects your health, comfort, and home structure.

• Ideal Range: Maintain indoor humidity between 30% and 50%.

4. Properly Sized Fresh Air Ducts

In addition to ventilation systems like HRVs and ERVs, having a properly sized fresh air intake duct connected to your HVAC system is crucial. It allows controlled amounts of outside air to enter your home, diluting pollutants and maintaining positive pressure to keep contaminants out.

• Benefit: Steady, filtered fresh air supply without sacrificing heating or cooling efficiency.

• Important: Fresh air ducts must be sized correctly—too small won't help, too large wastes energy.

5. Heat Recovery Ventilators (HRVs) and Energy Recovery Ventilators (ERVs)

Modern, energy-efficient homes are tightly sealed, but that means indoor air gets trapped. HRVs and ERVs exchange stale indoor air for fresh outdoor air while preserving your home's heating or cooling.

• Benefit: Healthy airflow with minimal energy loss.

• Key Difference: ERVs also manage humidity during the exchange, perfect for Alberta’s changing seasons.

6. Regular HVAC Maintenance

Even the best equipment can't deliver if it’s dirty or neglected. Professional HVAC maintenance ensures:

• Filters are replaced.

• Ducts are clean and sealed.

• Motors, coils, and electronics operate efficiently.

At Over the Top Heating, we use Fieldpiece Job Link® wireless tools to precisely measure airflow, static pressure, refrigerant charge, and system balance. It's another way we ensure your home stays comfortable—and healthy.
