FAQs
Why is proper ventilation important for homes and businesses in Evensville, and how does it impact indoor air quality?
Evensville’s seasonal humidity and temperature swings can trap pollutants such as dust, pet dander, cooking fumes, and volatile organic compounds (VOCs) inside tightly sealed buildings. A well-designed ventilation system continuously exchanges stale indoor air with fresh outdoor air, diluting contaminants and reducing odors, allergens, and excess moisture. This helps prevent mold growth, protects occupants with asthma or allergies, and promotes overall health and comfort while ensuring that your HVAC equipment operates efficiently.
What types of ventilation systems do you install or service, and which option is best for my Evensville property?
We install, service, and repair a full range of ventilation solutions, including exhaust-only fans (bath, kitchen, and attic), supply-only fans, balanced Heat Recovery Ventilators (HRVs), Energy Recovery Ventilators (ERVs), and integrated whole-house systems tied into existing ductwork. The “best” system depends on your home’s size, insulation level, occupancy, and specific indoor air quality concerns. In Evensville’s mixed-humid climate, ERVs are often recommended because they recover both heat and moisture, helping you stay comfortable year-round while controlling humidity.
How often should HVAC filters and ventilation components be inspected or replaced in Evensville’s climate?
High pollen counts and moderate humidity mean filters can clog quickly. We advise checking 1-inch pleated filters monthly and replacing them every 60–90 days, or more frequently if you have pets or allergies. Thicker media and HEPA filters typically last 6–12 months. HRV/ERV cores, exhaust fan housings, and outdoor intake screens should be inspected and cleaned at least once a year. Regular maintenance prevents airflow restrictions, lowers energy bills, and extends equipment life.
Can a balanced ventilation system lower my energy bills while maintaining comfort?
Yes. Balanced systems like HRVs and ERVs transfer heat (and, in ERVs, moisture) between outgoing and incoming air streams. In winter, they pre-warm fresh air; in summer, they help expel heat and humidity. This reduces the load on your furnace and air conditioner, cutting energy consumption by up to 30 % compared with simple exhaust-only strategies. Proper installation and commissioning are critical to realize these savings.
How does humidity control integrate with ventilation and air conditioning in Evensville?
Evensville often experiences humid summers and drier winters. Integrating ventilation with dehumidifiers or ERVs lets you bring in fresh air without introducing excessive moisture in summer. During winter, ERVs help retain indoor humidity so air doesn’t become overly dry. Coupled with a correctly sized air conditioner and smart thermostat, this balanced approach keeps relative humidity in the ideal 30–50 % range, preventing mold, wood warping, and static electricity.
What should I expect during a professional ventilation system maintenance visit in Evensville?
Our NATE-certified technicians will: (1) inspect and clean fans, ducts, and grilles; (2) replace or wash filters; (3) verify HRV/ERV core cleanliness and defrost operation; (4) check airflow with a flow hood or anemometer to ensure balanced supply and exhaust; (5) test controls, dampers, and safety interlocks; and (6) look for duct leaks or insulation issues. We’ll provide a written report and recommendations so you can keep your indoor air fresh, healthy, and energy-efficient all year.
