Air Quality
Whole-home air quality solutions for London, ON. Humidifiers, HEPA purifiers, UV germicidal lights, and HRVs installed by certified HVAC technicians.
Health Canada data shows that indoor air can be 2 to 5 times more polluted than outdoor air, and Canadians spend up to 90% of their time indoors. In London, Ontario homes, the combination of cold, dry winters and tightly sealed modern construction creates specific air quality challenges: low humidity that damages hardwood and irritates airways, trapped allergens and VOCs, and stale air that accumulates in energy-efficient homes. Corner Gas HVAC supplies and installs a complete range of whole-home indoor air quality solutions integrated directly into your existing HVAC system: whole-home humidifiers, HEPA-grade air purifiers, UV-C germicidal lights, and heat recovery ventilators (HRVs). We assess your home's specific needs and recommend the right combination of products with no upselling and no pressure, just honest guidance.

Whole-Home Humidifiers for London, Ontario Winters
London winters regularly push indoor relative humidity below 20%, which is well below Health Canada's recommended 30 to 55% range. At these levels, London homeowners experience dry, cracked skin, irritated sinuses and airways, increased static electricity, and long-term damage to hardwood floors and wooden furniture. A whole-home bypass or fan-powered humidifier connects directly to your furnace and automatically maintains ideal humidity throughout every room, adjusting in real time as outdoor temperatures change. Installed cost ranges from $400 to $900 depending on the model, which is a fraction of the cost of replacing warped hardwood or managing chronic respiratory symptoms.
HEPA Air Purifiers & Whole-Home Filtration in London, ON
Portable room air purifiers filter only the air in a single room. Whole-home air purifiers installed in your HVAC ductwork filter every cubic foot of air that circulates through your home, continuously and automatically, without occupying floor space. HEPA-grade media filters and electronic air cleaners capture particles as small as 0.3 microns: dust, pollen, pet dander, mould spores, and fine particulate matter. For London households with allergy or asthma sufferers, whole-home filtration provides a level of protection that no portable unit can match.
UV-C Germicidal Lights: Mould, Bacteria, and Virus Control
UV-C germicidal lights installed in your HVAC air handler use ultraviolet light to neutralize biological contaminants, including bacteria, viruses, mould spores, and other pathogens, as air passes through the system. They are particularly effective at eliminating mould growth on the evaporator coil, which is the most common source of musty odours in London homes with central air conditioning. For households with allergy, asthma, or immune-compromised members, UV-C lights combined with HEPA filtration provide the most comprehensive indoor air quality protection available.
Heat Recovery Ventilators (HRVs) for Airtight London Homes
Homes built or renovated after 2000 in London are constructed to energy-efficiency standards that make them significantly more airtight than older housing stock. While this reduces heating and cooling costs, it also traps stale air, excess moisture, and indoor pollutants. An HRV continuously exchanges stale indoor air for fresh outdoor air while recovering up to 80% of the thermal energy from the outgoing air stream. The result is consistently fresh, healthy indoor air without the energy penalty of opening windows in a London winter. HRVs are strongly recommended by Health Canada for all new and recently renovated homes.

Call (519) 649-0166Health Canada recommends maintaining indoor relative humidity between 30% and 55%. In Ontario winters, uncontrolled indoor humidity often drops below 20%, causing dry skin, irritated airways, and static electricity. A whole-home humidifier automatically maintains the ideal level without any manual adjustment.
A humidifier adds moisture to the air to increase humidity levels. An air purifier removes particles, allergens, and contaminants from the air. They serve different purposes and many homes benefit from both. A humidifier addresses dry air problems; an air purifier addresses air quality and allergen issues.
Yes, when properly sized and installed. Whole-home systems that integrate with your HVAC ductwork are significantly more effective than portable room units because they filter all the air circulating through your home, not just the air in one room. High-efficiency media filters and electronic air cleaners can remove 95% or more of airborne particles.
A Heat Recovery Ventilator (HRV) continuously exchanges stale indoor air for fresh outdoor air while recovering most of the heating or cooling energy. If your home was built after 2000 or has been extensively renovated for energy efficiency, it's likely quite airtight and an HRV is strongly recommended to maintain healthy air quality. Older, leakier homes may have adequate natural ventilation.
UV germicidal lights are effective at neutralizing biological contaminants including mould spores, bacteria, and some viruses. For allergy and asthma sufferers, combining UV lights with a high-efficiency air filter provides the most comprehensive protection. Many customers report significant improvement in symptoms after installing these systems.
A whole-home bypass humidifier typically costs $400–$700 installed, including the unit and labour. Fan-powered humidifiers, which are more effective for larger homes, run $600–$900 installed. The ongoing operating cost is minimal, mainly the cost of the water used and an annual maintenance visit to replace the water panel.
