Customer Questions
Who Makes Quest?
Quest dehumidifiers are proudly manufactured in the United States, specifically in Madison, Wisconsin. This is the home base of Therma-Stor LLC, the company behind the Quest brand. Therma-Stor has built a strong reputation in the HVAC and indoor air quality industries for producing high-performance, durable, and energy-efficient dehumidification systems.
Is installation difficult or do I need a professional?
While many Quest units are plug-and-play, larger models or those requiring overhead mounting may need a professional HVAC technician for safe and proper installation.
How do I know which Quest dehumidifier model is right for my space?
Start by measuring the square footage and ceiling height of your space. Then, consider moisture levels and how often the area is in use. Quest offers models with capacities ranging from around 70 to over 500 pints per day, so there’s an option for everything from small grow rooms to large industrial spaces.
What kind of maintenance is required?
Routine maintenance includes checking and replacing filters regularly, inspecting drainage lines, and cleaning the coils periodically. Most users find the upkeep simple and manageable.
How often do I need to clean or change the filter?
Most customers check the filter every 1–3 months. Depending on dust levels and usage, you may need to clean or replace it quarterly.
What is the warranty on Quest dehumidifiers?
Quest dehumidifiers come with a 5-year warranty on parts and refrigerant system components, offering long-term reliability and peace of mind.
How noisy are Quest dehumidifiers?
Noise levels vary by model, but most units are quiet enough for use in occupied commercial spaces. For grow rooms and workspaces, the sound is often comparable to a running HVAC system.
Can I run the dehumidifier continuously?
Yes, most Quest dehumidifiers are built for continuous operation. They include features like automatic defrost and humidity set points to maintain consistent performance without constant supervision.
