Air Purifiers & Filtration — Cleaner, Healthier Air for Your Home

We install high-performance filtration and purification systems that work seamlessly with your HVAC equipment:


  • Whole-Home Air Purifiers — Capture airborne particles and allergens throughout the entire home.
  • HEPA & Media Filters — Trap fine dust, pollen, and pollutants too small for standard filters.
  • UV Light Purifiers — Kill bacteria, mold spores, and viruses directly within your HVAC system.
  • Electronic Air Cleaners — Use static electricity to attract and remove fine particles for ultra-clean air.

These systems don’t just make your home cleaner—they also keep your HVAC equipment running efficiently by reducing buildup inside ducts and coils.

Humidity Control — Balance Moisture for Year-Round Comfort

Humidity levels play a major role in both comfort and health. Ascend Mechanical installs whole-home solutions that keep your home’s air perfectly balanced:


  • Humidifiers — Add moisture to dry winter air, preventing static, dry skin, and damage to wood furnishings.
  • Dehumidifiers — Control excess humidity during summer months, reducing musty odors and mold growth.

Maintaining ideal indoor humidity (around 40–50%) helps you feel more comfortable, breathe easier, and protect your home from seasonal wear and tear.

Ventilation Solutions — Fresh Air Without Energy Waste

Today’s airtight homes need controlled ventilation. Our technicians can install Energy Recovery Ventilators (ERVs) or Heat Recovery Ventilators (HRVs) that exchange stale indoor air for fresh outdoor air—without wasting heating or cooling energy. These systems help reduce indoor pollutants, moisture buildup, and stale air.
