Say goodbye to sticky floors and sky-high utility billsâHEPâs licensed HVAC pros bring Mountain City homeowners fresh comfort with precision dehumidifier installation that works hand-in-hand with your existing heating and air conditioning system. By drawing excess moisture out of the air before it circulates through your ducts, our high-efficiency units lighten the workload on your AC, lower energy consumption, and help prevent mold, mildew, and warped wood. The result is a crisp, balanced indoor climate that feels cooler at higher thermostat settings, so you save money while breathing easier.
From the first free humidity assessment to the final quality check, every step is handled by technicians who live right here in the High Country and understand its unique weather swings. We size the equipment to your square footage, seal leaky return lines, and calibrate smart controls that let you track savings in real time. With HEP, you donât just get a dehumidifierâyou get a long-term partner in home performance and a noticeable drop in discomfort the moment we flip the switch.
FAQs
Why is a whole-home dehumidifier important for homes in Mountain Cityâs climate?
Although Mountain City is in the mountains, our summer and shoulder-season humidity routinely climbs above 60%, which can leave indoor air feeling clammy, promote mold growth, and force your air conditioner to run longer. A dedicated, ducted dehumidifier pulls excess moisture out of the supply air before it circulates through the home, keeping indoor relative humidity in the ideal 40-50% range. This protects wood floors and furnishings, improves indoor air quality, and reduces the likelihood of dust-mites and allergens without over-cooling the space.
How does installing a dehumidifier improve the energy efficiency of my heating and air-conditioning system?
Air conditioners remove some moisture as a by-product of cooling, but they are designed primarily to lower temperature, not humidity. When moisture levels are high, the thermostat often has to be set lower than is comfortable just to feel dry, which increases run-time and utility costs. A whole-home dehumidifier performs the latent (moisture) load work separately. Because dry air feels cooler, you can raise the thermostat 2-3°F and still feel comfortable, cutting cooling energy use by up to 15%. In winter, proper humidity also allows you to feel warmer at lower heat settings, reducing heating demand.
What size or capacity dehumidifier do I need for my house?
Sizing is based on total square footage, ceiling height, insulation level, air-infiltration rate, and the amount of moisture generated by occupants and activities. During an in-home assessment we use ACCA Manual J load calculations and indoor humidity measurements to determine the pints-per-day removal requirement. Most Mountain City single-family homes need a 70- to 120-pint unit integrated into the supply or return ductwork; larger homes or properties with indoor pools may require multiple units or a high-capacity 155-pint model. Proper sizing ensures efficient cycling and prevents short-cycling that can waste energy and wear out components.
Will adding a dehumidifier require major changes to my existing HVAC system, and how long does installation take?
In most cases, we connect the dehumidifier to the return or supply plenum, install a dedicated condensate drain line, wire it to a humidistat or integrate it with your smart thermostat, and program the HVAC controls so the fan circulates air when the dehumidifier calls for operation. No outdoor equipment or refrigerant lines are required. For typical attic, crawl space, or mechanical-closet installations, the project is completed in one day with minimal disruption. Homes with limited duct access may need duct modifications, adding only a few hours to the job.
What is the expected cost and are there rebates or incentives available in Mountain City or Tennessee?
Turn-key installation for a high-efficiency, ENERGY STARÂŽ rated whole-home dehumidifier generally ranges from $2,200 to $3,800, depending on capacity, duct modifications, and controls. Tennessee Valley Authority (TVA) EnergyRight programs periodically offer rebates of $150-$300 for qualifying indoor air-quality upgrades, and local utilities such as Mountain Electric Cooperative provide low-interest financing on your power bill. We handle all paperwork and verify eligibility during your free estimate.
How do I maintain my dehumidifier to keep it running efficiently?
Maintenance is straightforward: (1) replace or wash the unitâs air filter every 3-6 months, or more often if you have pets; (2) make sure the condensate drain line remains clearâadding an optional float switch provides overflow protection; (3) have our technician inspect the coil, blower wheel, and electrical connections annually during your HVAC tune-up; and (4) keep the humidistat set between 40-50% RH year-round. With routine care, modern dehumidifiers last 8-15 years and typically carry a 5-year compressor and parts warranty.
