FAQs

Why do I need a whole-home dehumidifier in Oliver Springs when I already have air conditioning?

During our humid East Tennessee summers, outdoor relative humidity often hovers between 70 % and 90 %. Your air conditioner does remove some moisture, but its primary job is to lower air temperature. When temperatures are mild—especially spring and fall—the AC may not run long enough to pull sufficient moisture from the air. A dedicated dehumidifier monitors humidity independently of temperature, keeping indoor RH in the ideal 45–55 % range. This improves comfort, protects wood floors and furniture from swelling or mold, and helps prevent musty odors and allergy-triggering dust mites.

How does a professionally installed dehumidifier integrate with my existing HVAC system?

We install the unit in line with your supply or return ductwork, usually near the air handler. The dehumidifier draws warm, moist air from the return plenum, removes water over a refrigerated coil, and then sends the dry, conditioned air back into the supply side. A dedicated condensate line drains the collected water to a floor drain or condensate pump. The system is controlled by either its own humidistat or a combined thermostat/humidistat, so it operates only when indoor RH rises above your setpoint—independent of the cooling cycle.

What size dehumidifier do I need for my home, and how do you determine it?

Sizing is based on square footage, volume of conditioned space, typical occupancy, and infiltration rates. We start with ACCA Manual LLH guidelines, measure the home’s cubic feet, and consider local design humidity (about 88 grains per pound in Oliver Springs). For most 2,000–3,000 sq ft homes, a 70–95 pint-per-day unit is sufficient, but larger or leakier homes may need 120 pints or more. A load calculation ensures the unit runs efficiently without short-cycling, which could waste energy and fail to control humidity.

What is the typical cost of installing a whole-home dehumidifier in Oliver Springs, and are there energy savings?

Installed prices generally range from $1,800 to $3,000, depending on capacity, duct modifications, and whether a condensate pump is required. Energy-efficient models draw about 4–6 amps (roughly 500–700 watts), and because they let you raise the thermostat 2–3 °F without losing comfort, homeowners often see 5–10 % cooling-season energy savings. Lower humidity also reduces mold remediation and wood repair costs—an often-overlooked long-term financial benefit.

How much maintenance does a central dehumidifier require?

Very little. Replace or clean the unit’s MERV-8 filter every 3–6 months, just like your HVAC filter. Make sure the condensate line stays clear; we flush it during your spring or fall HVAC tune-up. The refrigeration circuit is sealed, so no annual refrigerant checks are normally needed. With routine filter changes and an annual inspection, most units last 8–15 years.

How quickly can your team install a dehumidifier, and will it disrupt my daily routine?

Most installations take 4–6 hours. We schedule at your convenience, place drop cloths to protect flooring, and keep HVAC downtime to under 30 minutes while we tie into the ductwork. You can stay in the home during the entire process, and we perform a final walk-through to show you how to adjust the humidistat and change the filter. The only noticeable change should be drier, more comfortable air by the end of the day.
