FAQs
What exactly does a Certified Comfort Specialist do for my heating, ventilation, and air-quality needs?
A Certified Comfort Specialist is an HVAC professional who has completed advanced factory and industry training on installation, service, and system design. Beyond standard heating and cooling, we evaluate air flow, humidity levels, filtration, and ventilation to create a balanced indoor environment. In Jonesborough, that means sizing equipment for both summer humidity and winter temperature swings, recommending the right filtration or purification technology for local pollen counts, and ensuring your home meets Tennessee building-code requirements for fresh-air exchange.
Why is indoor air quality such a big concern in the Jonesborough area?
Washington County’s beautiful scenery also brings high tree, grass, and ragweed pollen, plus humidity that can promote mold. Many homes are now built or remodeled to be “tighter,” trapping contaminants such as cooking grease, cleaning chemicals, pet dander, and even radon. Because winters are relatively mild, HVAC systems may run at lower speeds, circulating the same air for long periods. Good filtration, proper ventilation, and humidity control reduce allergy symptoms, protect wood finishes, and create a healthier living space year-round.
How often should I change my HVAC filter and what type works best?
For most Jonesborough households, we recommend inspecting the filter monthly and replacing it every 60–90 days. If you have pets, allergies, or run the system continuously, replacing it every 30–45 days is wiser. Look for a pleated filter with a MERV rating of 8–11; it captures fine particles without over-restricting airflow. Higher MERV (13+) is fine if your system is designed to handle the static pressure, but always verify with a technician first. We keep a full selection of sizes in stock and can show you how to swap them safely.
My house was built in the 1960s. What ventilation upgrades are available without major remodeling?
Older Jonesborough homes often rely on passive air leaks that no longer meet today’s health standards. We can install: • Energy-Recovery Ventilators (ERVs) or Heat-Recovery Ventilators (HRVs) that exchange stale indoor air with fresh outdoor air while conserving energy. • Dedicated exhaust fans in kitchens, baths, and laundry rooms with timers or humidity sensors. • In-line duct fans that boost fresh air through existing ductwork. • Ductless mini-split systems with built-in filtration and optional outside-air kits for rooms without ductwork. These options usually fit in attics or crawl spaces and tie into your current electrical system, keeping disruption minimal.
Will a smart thermostat really improve comfort and save money?
Yes. Modern Wi-Fi thermostats learn your schedule, adjust temperature based on outdoor conditions, and send maintenance reminders. In Jonesborough’s variable spring and fall weather, that means shorter run times on mild days and humidity control on muggy nights, cutting energy use by 10–15 %. Many models integrate with air-quality accessories—automatically activating your ERV when CO₂ rises or turning on the dehumidifier when humidity tops 55 %. We handle setup, app configuration, and show you how to create geofencing rules so the system shifts to eco-mode when you leave town.
How can I tell if my home needs a whole-house air purifier or dehumidifier?
Warning signs include persistent musty odors, visible dust within a day of cleaning, condensation on windows, or family members with frequent allergy or respiratory issues. We offer indoor air-quality audits that measure particulate matter (PM2.5), volatile organic compounds (VOCs), carbon dioxide, and relative humidity. If PM levels exceed 35 µg/m³ or humidity stays above 60 %, we may recommend a whole-home media air cleaner, UV-light purifier, or a central dehumidifier tied into your ductwork. These devices run quietly in the background, lowering airborne irritants and keeping humidity in the ideal 40–50 % range, protecting both health and home.
