Why Indoor Air Quality Matters for Westmont Homes
Westmont sits in a part of DuPage County where seasonal swings are real and significant. Winters can be long and dry, leaving indoor air feeling stale and irritating to sinuses and skin, while summers bring the kind of heavy humidity that settles into every corner of your home. These conditions create an environment where dust, allergens, and moisture imbalances can affect how comfortable your home feels day to day.
Improving indoor air quality is not just about allergies or odors. It is about creating a living space where your family or employees genuinely feel comfortable year round. McNally’s has been serving the Westmont community for years and has been voted the Best Heating and Air Conditioning Company multiple times because we approach every home with the care and attention it deserves.

Frequently Asked Questions
How do I know if my Westmont home has an indoor air quality problem?
Common signs include persistent dust buildup, musty or stale odors, frequent allergy symptoms indoors, or dry and irritated skin during winter months. The most reliable way to know for sure is to schedule a professional air quality test. Our team can assess your home and give you a clear picture of what is happening with the air you breathe. Schedule an air quality evaluation today.
Do I need both a humidifier and a dehumidifier in the Westmont area?
It is actually quite common for DuPage County homeowners to benefit from both. Winters here tend to be dry, which is where a whole-home humidifier adds real comfort and protects wood floors and furniture. Summers, on the other hand, can be quite humid, and a dehumidifier helps maintain a comfortable moisture level without overworking your air conditioner. Our team can assess your home and recommend the right setup based on your actual conditions.
What is a UV germicidal light and how does it work in my HVAC system?
A UV germicidal light is installed inside your HVAC system, typically near the coil or in the ductwork, where it emits ultraviolet light that disrupts the cell structure of bacteria, mold spores, and other biologicals as they pass through. It is a continuous, low-maintenance way to reduce certain contaminants that can circulate through your home every time your system runs. It works alongside your existing filtration rather than replacing it. Learn more about our full range of air purification services.
What is an energy recovery ventilator and would it help my home?
An energy recovery ventilator, or ERV, brings fresh outdoor air into your home while transferring heat or coolness from the outgoing stale air so that energy is not wasted. In tightly sealed homes, which are increasingly common in Westmont and surrounding areas, ventilation can be limited and air can feel stuffy or recycled. An ERV is a smart solution for improving freshness without sacrificing efficiency. Our technicians can evaluate whether your home would benefit from one.
Can air purification services help with my home's ductwork?
Air purification and duct cleanliness go hand in hand. If your ducts have accumulated dust, debris, or mold, even the best air cleaner will be working against a constant source of contamination. We often recommend pairing air quality upgrades with a professional air duct cleaning to give your system a clean foundation. Our team will be straightforward with you about what is actually needed based on what we find.
