FAQs
Why is indoor air quality (IAQ) such a concern for Dunlap homeowners?
Although Dunlap enjoys clean outdoor air for most of the year, homes are built increasingly airtight to conserve energy. This keeps conditioned air inside, but it also traps pollutants such as dust, pollen, pet dander, and chemical vapors. Because the average person spends 90% of their time indoors, poor IAQ can aggravate allergies, trigger asthma, promote respiratory illnesses, and even cause headaches or fatigue. Improving indoor air quality helps protect your family’s health while keeping your HVAC system running efficiently.
What are the most common indoor air pollutants we find during service calls in Dunlap?
Our technicians regularly measure: • Particulate matter (PM2.5 and PM10) from dust, soil tracked indoors, and cooking. • Biological contaminants such as mold spores, bacteria, pet dander, and pollen. • Volatile organic compounds (VOCs) released by cleaning products, paints, furniture, and carpeting. • Excess humidity that encourages mold growth and dust‐mite populations. • Combustion by-products like carbon monoxide (CO) and nitrogen dioxide (NO₂) from gas appliances or attached garages. Each home is unique, which is why we recommend a professional IAQ assessment before suggesting solutions.
How can my heating and air conditioning system help improve indoor air quality?
A properly designed HVAC system does more than heat and cool: 1) Filtration: High-MERV filters or HEPA bypass filters capture fine particles before they circulate. 2) Purification: UV-C lights and photocatalytic oxidation (PCO) units neutralize mold spores, bacteria, and VOCs. 3) Humidity Control: Whole-home humidifiers add moisture in dry winters, while variable-speed air conditioners or dedicated dehumidifiers pull moisture out during humid weeks. 4) Balanced Ventilation: Energy or heat-recovery ventilators (ERV/HRV) exchange stale indoor air with fresh outdoor air without excessive energy loss. Pairing these technologies with regular maintenance keeps IAQ at healthy levels.
What ventilation solutions do you install, and which one is best for my home?
We offer three main categories: • Spot Ventilation (bathroom & kitchen exhaust fans) – a cost-effective way to remove moisture and odors from specific areas. • Balanced Mechanical Ventilation – HRVs and ERVs provide a steady supply of fresh air while recovering up to 80% of the energy in the outgoing air; ideal for newer, tight homes. • Whole-House Fans or Economizer Add-Ons – when outside temperatures permit, these draw cool outdoor air through open windows and exhaust hot air from the attic. The right solution depends on your home’s construction, occupancy patterns, and existing HVAC equipment. Our comfort consultant will run an airflow calculation and recommend the most energy-efficient option.
How often should I replace filters and schedule IAQ/HVAC maintenance?
• Standard 1-inch fiberglass filters: every 30 days. • Pleated MERV 8–11 filters: every 60–90 days, or monthly if you have pets or allergies. • High-MERV or media cabinet filters: every 6–12 months. • HEPA bypass filters: check quarterly; replace annually. In addition, schedule professional HVAC maintenance twice a year (spring and fall). During each visit we clean coils, inspect ducts for leaks, test carbon-monoxide levels, and verify humidity and airflow settings to keep your IAQ devices working at peak efficiency.
Can smart thermostats and indoor air quality monitors really make a difference?
Yes. Today’s smart thermostats integrate with compatible IAQ accessories, automatically turning on your fan or ERV when pollutant or humidity levels rise. Stand-alone IAQ monitors continuously track PM2.5, VOCs, CO₂, temperature, and humidity, sending alerts to your phone. By combining these devices with a Wi-Fi thermostat, you gain real-time data, energy savings, and peace of mind. Our technicians can help you choose models that work with your existing HVAC equipment and set them up for effortless monitoring.
