FAQs
Why should I install a dehumidifier in my Guild homeâs crawl space?
Guildâs warm, often humid climate makes crawl spaces prone to excess moisture. High humidity encourages mold growth, wood rot, and pest infestations, all of which can damage your homeâs structure and negatively affect indoor air quality. A dedicated crawl-space dehumidifier keeps relative humidity around 50%, protecting your beams, sub-flooring, and insulation while preventing musty odors from migrating into your living areas.
How is a crawl-space dehumidifier different from a portable unit I can buy at a big-box store?
Crawl-space dehumidifiers are purpose-built: they offer higher moisture-removal rates (up to 90+ pints per day), operate efficiently at lower temperatures, and are designed to connect to a permanent drain so you never empty buckets. They also feature coated coils to resist corrosion in damp, enclosed areas and can be tied into your existing HVAC or a dedicated duct system for more even air circulation.
What size or capacity dehumidifier do I need for my crawl space?
Capacity is based on square footage, ceiling height, and current moisture level. As a rule of thumb, crawl spaces under 1,500 sq ft typically need a 55-70-pint unit, while larger or wetter spaces may require 90-120 pints. During our free inspection we measure relative humidity, check for standing water, and assess air flow to recommend the right-sized model so the unit isnât undersized (runs constantly) or oversized (short-cycles and wastes energy).
How is the dehumidifier installed and how long does it take?
Installation usually takes one day. First, we seal foundation vents and any obvious air leaks so outside moisture canât re-enter. We then place a vapor barrier over the soil if one isnât already present. The dehumidifier is mounted on isolation pads or hung from joists, connected to a dedicated GFCI outlet, and hard-ducted to discharge dry air evenly. Finally, we route a condensate line to a sump pump or exterior drain and test the system to ensure humidity drops to target levels.
Will a crawl-space dehumidifier lower my heating and cooling costs?
Yes. Drier air is easier to heat and cool, so your HVAC system doesnât have to work as hard. Studies show homeowners can save 10â15 % on energy bills once humidity is controlled. Eliminating moisture also prevents insulation from getting damp and losing R-value, further boosting efficiency and comfort in living spaces above the crawl.
What maintenance is required after installation?
These units are low-maintenance: change or vacuum the air filter every 3â6 months, and schedule an annual service visit where we clean the coil, inspect the drain line, and verify the humidistatâs calibration. Most models include auto-defrost and self-diagnostics, and they carry 5-year bumper-to-bumper warranties, giving you long-term peace of mind.
