FAQs
Why should I add a whole-home dehumidifier to my air-conditioning system in Elizabethton?
East Tennessee’s warm summers are accompanied by humidity levels that routinely climb above 70 %. Excess moisture makes your home feel hotter than the thermostat reading, encourages mold growth, and can warp wood flooring and furniture. A whole-home dehumidifier removes that excess moisture as air passes through your HVAC ductwork, letting you set the thermostat a few degrees higher while still feeling comfortable. The result is better indoor air quality, lower cooling loads, and protection for your home’s structure and contents.
How is a dehumidifier installed with my existing heating and air-conditioning equipment?
Most whole-home units are mounted in line with your supply or return ductwork near the air handler. Our technicians cut a small access point in the duct, seal the dehumidifier to the opening, and run a dedicated condensate drain line to a nearby floor drain or condensate pump. A low-voltage control cable ties the dehumidifier into your HVAC thermostat or a separate wall control. Electrical power is supplied either by a standard 120-V outlet or a hard-wired connection, depending on model. The entire installation is designed so your furnace or heat pump fan circulates air through the dehumidifier whenever humidity is above your set point.
What size dehumidifier does my Elizabethton home need?
Capacity is measured in pints of water removed per day. The right size depends on square footage, ceiling height, typical indoor humidity, and how airtight your home is. As a rule of thumb, a 2,000 ft² home with average humidity needs a 70-pint unit, while larger or leakier homes may require 90–120 pint models. During our free in-home evaluation we take humidity readings and perform a Manual J moisture load calculation to recommend a properly sized system—oversizing wastes energy and undersizing won’t solve the problem.
Will adding a dehumidifier lower my energy bills?
Yes—by taking moisture out of the air, your comfort level rises at higher temperatures. Most homeowners can raise the AC set point 2-4 °F and still feel just as cool, trimming 5-10 % off summer electricity costs. Removing humidity also reduces the run time and cycling stress on your air conditioner, which can extend its lifespan and cut maintenance costs. While a dehumidifier uses some electricity, modern ENERGY STAR® models draw only about the same power as a desktop computer, so the net savings usually outweigh the added consumption.
How long does installation take and will it disrupt my household?
A typical retrofit in Elizabethton takes 3–5 hours for one technician and can be completed in a single visit. We begin by laying down protective floor coverings, then shut off your HVAC power, install the unit, add the drain line, wire the controls, and restart the system. The only water shutdown needed is a brief test of the condensate drain. You can stay in the home the entire time, and your heating or cooling will be off for less than an hour while we make the duct connection.
What maintenance is required and do you offer service plans?
Whole-home dehumidifiers are low-maintenance: clean or replace the air filter every 6-12 months, check the drain line for clogs, and have the coil inspected annually. During our Comfort Shield service plan visits we clean the unit, verify refrigerant charge, sanitize the drain pan, and calibrate the humidistat. The plan also includes priority scheduling, waived diagnostic fees, and discounts on any repairs. Regular upkeep maximizes efficiency and keeps most units operating 10–15 years.
