FAQs
Why is proper ventilation important for indoor air quality in McDonald homes and businesses?
Ventilation continually replaces stale indoor air with fresh outdoor air, diluting pollutants such as dust, pet dander, cooking fumes, and volatile organic compounds (VOCs). In McDonald’s four-season climate, homes are often tightly sealed for energy savings, which can trap contaminants and excess moisture. Adequate mechanical ventilation prevents this buildup, helping occupants breathe easier, reducing allergy and asthma triggers, and protecting the building from mold and structural damage.
What is the difference between a Heat Recovery Ventilator (HRV) and an Energy Recovery Ventilator (ERV), and which one should I choose?
Both HRVs and ERVs exhaust stale air while supplying fresh air, but they handle moisture differently. An HRV transfers only heat between outgoing and incoming airstreams, making it ideal for colder climates where indoor humidity needs to be expelled. An ERV transfers both heat and a portion of the moisture, helping retain humidity in winter and reduce it in summer. Because McDonald experiences humid summers and cold winters, the best choice depends on your home’s specific moisture levels: HRVs suit homes prone to winter condensation, while ERVs work better if air-conditioning runs frequently in summer. A professional load calculation and humidity assessment will pinpoint the right option.
How often should I change or clean my HVAC air filters to maintain good air quality?
Check disposable fiberglass filters every 30 days and replace them at least every 60–90 days. Pleated high-efficiency filters should be inspected monthly and changed every 90 days, or sooner if you have pets, smokers, or allergies. Washable electrostatic filters require rinsing about once a month. Regular filter maintenance keeps airflow unobstructed, improves system efficiency, and reduces the circulation of dust and allergens.
What signs indicate my ventilation system needs professional service?
Common warning signs include persistent odors, visible mold on vents, excessive dust accumulation, uneven temperatures between rooms, whistling or rattling noises in ductwork, and higher energy bills without changes in usage. If carbon-dioxide levels feel stuffy even with windows closed, or if occupants experience more frequent respiratory symptoms indoors, schedule an inspection. Prompt service prevents larger repairs and protects indoor air quality.
Can upgraded ventilation really lower humidity and prevent mold growth in McDonald’s climate?
Yes. McDonald’s humid summers can push indoor relative humidity above 60 %, the threshold where mold thrives. Balanced or supply-only ventilation paired with dehumidification extracts moisture-laden air while bringing in conditioned fresh air, keeping relative humidity in the 30–50 % range. This inhibits mold, protects wooden furnishings, and improves comfort. Adding a whole-home dehumidifier or an ERV can further stabilize indoor moisture.
How does balanced ventilation improve energy efficiency compared with exhaust-only solutions?
Balanced systems (HRVs or ERVs) use two fans to exhaust stale air and introduce fresh air at equal volumes, preventing pressure imbalances that can draw unconditioned outdoor air through cracks. The built-in heat exchanger recovers 60–90 % of the energy from outgoing air, pre-warming or pre-cooling the incoming stream. This process reduces the workload on your furnace and air conditioner, cutting annual heating and cooling costs by up to 20 % while ensuring a steady supply of fresh air.
