FAQs
What does it mean that your technicians are NATE-certified, and why should I care?
NATE (North American Technician Excellence) certification is the HVAC industry’s most widely recognized credential. To earn it, a technician must pass rigorous, proctored exams that cover heating, cooling, ventilation, and indoor air quality (IAQ) best practices. When you invite one of our NATE-certified technicians into your Friendsville home, you’re getting a proven expert who can diagnose issues accurately, install equipment to manufacturer specs, and optimize system efficiency so you save on energy and avoid premature breakdowns.
Which ventilation and indoor air quality (IAQ) services do you offer in Friendsville?
We provide complete IAQ solutions—including whole-home air filtration systems, UV germicidal lights, energy-recovery ventilators (ERVs), humidifiers, dehumidifiers, and duct cleaning. Our NATE-certified technicians also perform airflow balancing, duct sealing, and fresh-air intake design to ensure your home meets the latest ASHRAE ventilation standards while remaining energy-efficient.
How do I know whether I need an air purifier, dehumidifier, or another IAQ product?
Every house is different. We start with an on-site IAQ assessment that measures particulate levels, relative humidity, carbon dioxide, and volatile organic compounds (VOCs). We then explain the data, show you problem areas (such as excess humidity in basements or high pollen infiltration), and recommend targeted solutions—whether that’s a high-MERV media filter to trap allergens, a dehumidifier to maintain 45–55 % RH, or an ERV to bring in fresh outdoor air without wasting energy.
How often should I replace my HVAC filter in Friendsville’s climate?
With our region’s mix of spring pollen, summer humidity, and winter furnace use, most homes benefit from replacing a standard 1-inch filter every 30–60 days. If you have pets, allergies, or a higher-MERV pleated filter, inspect it monthly and change it when it looks gray on the intake side. Upgrading to a 4-inch media filter or an electronic air cleaner can extend the change interval to 6–12 months while improving air quality.
Will better ventilation increase my energy bills?
Not if it’s done correctly. Modern ERVs and HRVs (heat-recovery ventilators) exchange stale indoor air with fresh outdoor air while transferring up to 80 % of the outgoing heat or cooling to the incoming air. That means you gain the health benefits of fresh air without a big energy penalty. Our technicians calculate the optimal ventilation rate for your home so the system runs only as much as needed, further controlling operating costs.
Do you offer maintenance plans for ongoing air quality and HVAC performance?
Yes. Our Comfort & Air Quality Club includes two seasonal tune-ups (spring AC and fall heating), a full IAQ check, filter replacement or cleaning, priority scheduling, and a 15 % discount on repairs. Regular maintenance keeps your Friendsville HVAC system efficient, extends equipment life, and ensures that IAQ devices like UV lights and ERV cores are cleaned and operating at peak performance.
