Frequently Asked Questions
What's the best air purifier for a Pittsburgh home?+
For most homes, a whole-home media air cleaner with a MERV 13–16 filter handles allergens, pet dander, and smoke effectively. Homes with severe allergies or immune-compromised residents benefit from a true HEPA system or UV germicidal light paired with media filtration.
Do I need a humidifier in Pittsburgh winters?+
Most Pittsburgh homes drop to 15–25% indoor humidity in winter, which causes dry skin, static, cracked wood, and worse cold symptoms. A whole-home humidifier integrated with your furnace maintains 35–45% humidity automatically.
How often should I clean my air ducts?+
Most homes only need duct cleaning every 5–7 years. We recommend it sooner after a renovation, water damage, pest issues, or if you notice visible dust discharge from registers.
Will an air purifier help with allergies?+
Yes — a properly sized whole-home purifier with MERV 13+ filtration captures pollen, pet dander, dust mite debris, and mold spores before they recirculate. Most clients notice symptom improvement within two to four weeks.
Are UV lights worth it?+
UV germicidal lights installed at the evaporator coil prevent biological growth on the coil and improve airflow and efficiency. Lights installed in the supply ductwork can reduce airborne pathogens. Both are affordable add-ons during a system install.
