Whole-house ERV
Whole-house ERV | Ventilation and Air Quality | Heating and Air Conditioning | Tazewell
Imagine a Tazewell home where every breath feels like a cool mountain morning—crisp, clean, and perfectly balanced. HEP’s whole-house ERV system seamlessly blends fresh outdoor air with your heating and air conditioning, recovering energy that would otherwise be lost while filtering out pollutants, allergens, and excess humidity. The result is year-round comfort that doesn’t compromise efficiency or your utility budget.
Our licensed technicians design each system around your home’s unique layout, sealing leaky ducts, tuning airflow, and calibrating controls so you can set the thermostat and forget it. Because the ERV continuously exchanges stale indoor air for fresh, conditioned air, you’ll notice fewer odors, less dust, and more consistent temperatures from attic to basement—even during Tazewell’s most muggy summers and chilly winters.
Backed by HEP’s 24/7 service promise, you can trust that your investment in better ventilation and air quality will keep paying dividends for years to come. We’re local, we’re certified, and we’re ready to help you breathe easy.
FAQs
What is a whole-house ERV and how does it improve indoor air quality in Tazewell homes?
A whole-house Energy Recovery Ventilator (ERV) is a mechanical ventilation system that continuously exchanges stale indoor air with fresh outdoor air while transferring heat and moisture between the two air streams. In Tazewell, where seasonal humidity levels and temperature swings can trap pollutants indoors, an ERV helps remove contaminants such as dust, allergens, and VOCs. At the same time, it balances indoor humidity and minimizes energy loss, so you get cleaner, healthier air without a big spike in utility bills.
Will an ERV work with my existing heating and air conditioning system?
Yes. ERVs are designed to integrate with most central HVAC systems, whether they’re gas furnaces, heat pumps, or dual-fuel setups common in Tazewell. The ERV ties into your home’s supply and return ductwork, operating in tandem with the blower. Our technicians perform an airflow calculation to ensure proper sizing and compatibility, so your current heating and cooling performance is not compromised and, in many cases, is enhanced by balanced ventilation.
How much energy can I save with an ERV compared to traditional exhaust-only ventilation?
Traditional exhaust fans simply expel conditioned indoor air and pull in unconditioned outdoor air through leaks, wasting heating and cooling dollars. An ERV captures 60–80% of the heat (and moisture) from the outgoing air and transfers it to the incoming air. In Tazewell’s mixed-climate zone, this heat- and moisture-exchange ability can cut ventilation-related energy costs by up to 40%, translating to noticeable savings on your monthly utility bills while maintaining fresh air.
What maintenance does a whole-house ERV require?
ERV maintenance is straightforward. Homeowners should: 1) Inspect and replace or wash the ERV filters every 3–6 months (more often during Tazewell’s high-pollen seasons). 2) Clean the core and internal fans annually—our technicians can handle this during a routine HVAC service visit. 3) Check that the exterior intake/exhaust hoods stay clear of debris and snow. Regular maintenance keeps airflow balanced, prevents mold growth in the core, and preserves energy-recovery efficiency.
Is an ERV noisy, and where is it installed?
Modern ERVs are engineered for quiet operation. The unit is typically installed in a mechanical room, basement, or attic space and connected to existing ductwork with insulated flex or rigid ducts. Sound-dampening mounts and low-RPM ECM motors keep operational noise comparable to a refrigerator’s background hum. Most homeowners in Tazewell report that they don’t notice the ERV running once it’s properly balanced and insulated.
What is the average cost of installing a whole-house ERV in Tazewell, and are there incentives available?
Installed costs in the Tazewell area generally range from $2,500 to $4,500, depending on the size of the home, duct modifications, and the ERV’s efficiency rating. Tennessee and Virginia residents may qualify for federal tax credits of up to 30% of the equipment and labor under the Inflation Reduction Act’s energy-efficiency provisions. Local utility rebates occasionally apply as well. Our team can provide a free in-home estimate and guide you through current incentive programs to lower your out-of-pocket expense.
