By focusing on precision installation, system compatibility, and long-term reliability, the team delivers a solution that keeps homes and businesses comfortable, healthy, and energy-efficient through every season.
The Crossville Climate Challenge
The plateau’s unique topography traps humid air masses rolling up from the Gulf, creating an environment where indoor relative humidity can stay above optimal levels for extended periods. Excess humidity can cause:
- Warped hardwood floors and swelling cabinetry
- Musty odors and stubborn mold or mildew growth
- Dust mite proliferation, triggering allergies
- Elevated cooling bills as air conditioners struggle to remove moisture
HEP addresses these issues head-on with dehumidifier installations designed for local humidity profiles, ensuring conditioned spaces maintain the recommended 30–50 % relative humidity range.
How Dehumidifiers Complement Heating and Air Conditioning
The Limits of Standard HVAC Moisture Removal
Traditional air conditioning equipment condenses water vapor as it cools air, but its primary purpose is temperature management. When humidity spikes, even a high-quality AC system can:
- Short-cycle, never running long enough to draw out adequate moisture
- Produce air that feels clammy despite achieving the target temperature
- Force occupants to lower the thermostat further, wasting energy and wearing out components
Introducing a dedicated dehumidifier offloads the moisture load, letting the air conditioner focus on temperature while the dehumidifier fine-tunes indoor humidity. The result is a balanced, comfortable environment at a higher setpoint—often 2–3 °F higher—without sacrificing comfort.
Whole-Home Dehumidifiers vs. Portable Units
HEP installs whole-home units that connect directly to the return ductwork of a central HVAC system. Compared to portable plug-in models, these systems offer:
- Higher extraction rates, removing pints of water per day instead of ounces
- Quiet operation away from living spaces
- Automatic drainage into a condensate line
- Unified controls integrated with existing thermostats or smart home platforms
- Balanced dehumidification across every conditioned room, not just a single area
The HEP Dehumidifier Installation Process

Common Myths About Humidity Control Debunked
-
“Running the air conditioner longer fixes moisture problems.”
Excess runtime cools air but can overshoot temperatures while still missing RH targets. Dedicated dehumidifiers operate independently for precise control. -
“Basements are the only spaces that need dehumidifiers.”
Humidity migrates upward; even second-floor bedrooms can suffer discomfort without balanced RH. Whole-home systems treat every zone. -
“Lowering the thermostat is more efficient than buying another appliance.”
Continually dropping temperature increases energy bills and creates uneven comfort. A correctly sized dehumidifier often pays for itself in saved cooling costs.
