FAQs

What causes musty odors in my Thorn Hill home, and how can a dehumidifier help?

Musty smells are almost always linked to excess moisture that allows mold and mildew to grow on walls, carpets, ductwork, and household contents. Thorn Hill’s humid summers and tightly sealed modern homes trap that moisture indoors. A whole-home dehumidifier draws humid air through the return ducts, removes the excess water, and delivers dry, conditioned air back to every room. By keeping indoor relative humidity in the 40–50 % range, mold spores stay dormant and the musty odor disappears without relying on scented sprays or candles.

How does installing a whole-home dehumidifier integrate with my existing HVAC system?

The dehumidifier is installed in line with your central heating and air-conditioning ductwork—usually between the return plenum and the supply trunk. It has its own fan that pulls air from the return side, extracts moisture over an internal coil, then sends the dry air back into the supply. Because it works independently, it can operate whether or not your air conditioner is running, giving you year-round humidity control. Our technicians also tie the unit into your HVAC control board or mount a dedicated wall humidistat so you can set your preferred humidity level just like a temperature setting.

Will adding a dehumidifier increase my utility bills?

A dehumidifier does use electricity, but most homeowners see little or no increase in their monthly bills. In fact, you may save energy because drier air feels cooler, allowing you to raise the thermostat two to three degrees without sacrificing comfort. Removing moisture also reduces the workload on your air conditioner, which can lower cooling costs and extend equipment life. ENERGY STAR®-rated models we install in Thorn Hill cost roughly $2–$4 per week to operate during peak summer humidity.

How do I know what size dehumidifier my home needs?

Sizing is based on square footage, the layout of your duct system, ceiling height, typical indoor moisture load, and local climate data for Thorn Hill. During a free home assessment, our comfort advisor measures each factor and uses ACCA Manual H guidelines to recommend the right capacity, expressed in pints per day. An undersized unit will run nonstop without reaching the target humidity, while an oversized unit may short-cycle and waste energy. We carry multiple sizes—from 70-pint models for smaller ranch homes to 130-pint units that handle large multi-level properties.

What should I expect during the installation process and how long will it take?

Most whole-home dehumidifier installations are completed in one day. We start by protecting floors and furnishings, then cut precise openings in the supply and return ducts for the unit’s inlet and outlet collars. Condensate is piped to a nearby floor drain or condensate pump, and an overflow safety switch is added to prevent leaks. Electrical wiring is brought to a dedicated 120 V or 240 V circuit, depending on model. Finally, we calibrate the humidistat and verify proper airflow and drainage before leaving your home as clean as we found it.

How often does a dehumidifier need maintenance and what does it involve?

Plan on a quick service visit once a year, ideally before peak humidity season. Our maintenance includes cleaning or replacing the air filter, inspecting the evaporator coil for dirt or bio-growth, flushing the condensate line to prevent clogs, checking fan motor amperage, and confirming the humidistat’s accuracy. Many Thorn Hill homeowners bundle dehumidifier care with their HVAC preventive maintenance plan, ensuring all comfort equipment is serviced during the same appointment and qualifying them for parts-and-labor discounts.
