FAQs
Why should I add a whole-home dehumidifier to my existing HVAC system in Tazewell?
Tazewell’s warm, humid summers often leave indoor humidity above the recommended 40–50 % range. Excess moisture can make your home feel hotter, force your air conditioner to work harder, encourage mold growth, and warp wood furnishings. A whole-home dehumidifier removes moisture before air is distributed through your ducts, improving comfort, protecting your home’s structure, and helping your HVAC system run more efficiently.
Can a dehumidifier be integrated with my current furnace and air conditioner, or will I need a completely new system?
In most cases, a whole-home dehumidifier is installed in the return-air plenum of your existing ductwork, so you do not need to replace your furnace or air conditioner. Our technicians tie the unit into the same supply and return ducts and wire it to your HVAC control board or a dedicated humidistat. We verify that your blower size and static pressure can handle the additional airflow resistance, making adjustments if needed.
Will running a dehumidifier increase my energy bills?
A dehumidifier does use electricity, but it often lowers overall cooling costs. By wringing out moisture before it reaches your living spaces, the air feels cooler at a higher thermostat setting—usually 2–3 °F higher—so your air conditioner runs less. Many homeowners see a net decrease in summer utility costs and less wear on the A/C compressor.
How long does professional installation take, and will my HVAC system be down during the process?
A typical whole-home dehumidifier installation in Tazewell takes 4–6 hours. We fabricate a short bypass duct, plumb the condensate drain, wire the electrical connections, and commission the unit. Your HVAC system is usually off for no more than 30–45 minutes while we tie into the ductwork, so downtime is minimal.
What maintenance does a central dehumidifier require after installation?
Maintenance is straightforward: (1) Clean or replace the dehumidifier’s air filter every 3–6 months; (2) Inspect and flush the condensate drain line annually to prevent clogs; (3) Have a technician check the refrigeration coil and blower wheel during your spring AC tune-up. With proper care, most units last 10–15 years.
Is a dehumidifier really necessary in Tazewell’s climate, or will my air conditioner handle moisture removal?
While air conditioners remove some moisture as a by-product of cooling, they are not designed to control humidity independently. During shoulder seasons or mild, muggy days when the AC runs short cycles, indoor RH can spike above 60 %. A dedicated dehumidifier operates whenever humidity rises, regardless of temperature, giving you stable, healthy air quality year-round in Tazewell.
