Breathe Easier: 5 Ways to Improve Indoor Air Quality in Your London, ON Home

Common signs include persistent dust despite frequent cleaning, musty odors, condensation on windows, increased allergy or asthma symptoms indoors, dry itchy skin or sore throats during winter, and visible mold growth. Hawana HVAC provides professional IAQ assessments for London homeowners to identify specific pollutants and recommend targeted solutions.

An HRV (Heat Recovery Ventilator) transfers only heat, making it ideal for cold climates where indoor air is often too dry in winter. An ERV (Energy Recovery Ventilator) transfers both heat and moisture, which helps maintain balanced humidity levels year-round. For Southwestern Ontario's climate with cold winters and humid summers, an ERV is often the better choice for maintaining comfort.

Whole-home humidifier installation costs range from $650-$1,500 depending on the type. Bypass models cost $500-$800 installed, fan-powered models cost $700-$1,000, and steam models cost $1,000-$1,500. Most London homeowners see payback within 1-2 heating seasons through improved comfort, reduced static electricity, and protection of wood furniture and floors.

For most London homes, MERV 8-11 is recommended for balancing filtration and airflow. MERV 8 captures pollen, dust mites, and mold spores. MERV 11 captures finer particles including pet dander and smoke. Homes with allergy sufferers should use MERV 11-13, but ensure your system can handle the higher resistance. We can assess your system and recommend the optimal MERV rating.

Yes. In-duct UV-C light systems neutralize up to 99% of airborne viruses, bacteria, and mold spores as air passes through your HVAC system. This technology is used in hospitals and commercial buildings and provides an extra layer of protection for your family's health, especially for households with immunocompromised individuals or severe allergies.

The National Air Duct Cleaners Association (NADCA) recommends duct cleaning every 3-5 years. However, clean more frequently if you have pets, smokers, recent renovations, visible mold, or family members with severe allergies or asthma. Professional duct cleaning removes accumulated dust, dander, and debris that gets recirculated through your home every time your system runs.

Absolutely. High-MERV filters capture pollen, mold spores, and dust mites. Whole-home humidifiers prevent dry airways that trigger asthma. UV lights kill mold and bacteria. HRV/ERV systems bring in fresh outdoor air while exhausting indoor pollutants. Many London homeowners report significant symptom reduction after implementing these IAQ solutions.

Aim for 35-45% relative humidity in winter. Below 30% causes dry skin, static shocks, and increased virus spread. Above 50% can cause window condensation and mold growth. A whole-home humidifier with automatic humidistat adjusts based on outdoor temperature to prevent window condensation while maintaining comfort. We set up optimal settings during installation.

Many London homes benefit from both. A humidifier adds moisture during dry winters, while an HRV/ERV brings in fresh air and exhausts stale indoor pollutants. An ERV also helps maintain humidity levels by transferring moisture between incoming and outgoing air. Together, they provide complete IAQ management — proper humidity plus fresh, filtered air year-round.

HRV/ERV installation in an existing home typically takes 1-2 days depending on accessibility and ductwork modifications needed. We work efficiently to minimize disruption, and our TSSA-certified technicians ensure proper integration with your existing furnace and ductwork. The result is continuous fresh air circulation throughout your entire home without losing energy.
