FAQs

Why should I install a whole-house dehumidifier in Speedwell’s climate?

Speedwell experiences long, humid summers and mild, damp winters, so excess indoor moisture is a year-round concern. A whole-house dehumidifier keeps relative humidity in the ideal 45–55 % range, which helps prevent mold growth, dust-mite proliferation, musty odors, warped wood, and peeling paint. Controlling humidity also makes your air conditioner work less hard, improves comfort at higher thermostat settings, and protects your home’s structure and furnishings.

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

We install the dehumidifier in line with your central ductwork—usually on the return side—so it treats all the air that moves through your heating and cooling system. The unit has its own blower and humidistat but can also be wired to work in tandem with your thermostat or HVAC fan. Moist air is drawn into the dehumidifier, moisture is condensed and drained away, and the dried air is redistributed through your supply ducts, ensuring balanced humidity in every room without adding another standalone appliance.

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

Proper sizing depends on your home’s square footage, ceiling heights, number of occupants, typical indoor moisture sources (cooking, showering, basement seepage), and infiltration rates. During our free in-home assessment, we measure the living area, inspect insulation and duct conditions, and take real-time humidity readings. Using these data and ACCA Manual Q guidelines, we recommend a unit with the correct pints-per-day removal capacity—usually 70–135 pints for most Speedwell homes—so you get efficient moisture control without excessive cycling or noise.

What is involved in the installation process and how long does it take?

A standard installation takes 4–6 hours: 1) We shut off power to the HVAC system and create an access point in the return plenum. 2) The dehumidifier is mounted on vibration-isolating brackets or placed on a dedicated platform. 3) We connect insulated flex or rigid duct runs to the intake and supply collars. 4) A condensate drain line is routed to your floor drain, sump pit, or condensate pump with an optional overflow safety switch. 5) We wire the unit to a 120 V or 240 V dedicated circuit and integrate controls with your HVAC thermostat if desired. 6) Finally, we test-run the system, verify drainage, set the humidistat, and review operation and maintenance with you.

How much maintenance does a whole-house dehumidifier require?

Maintenance is simple and can be done during your regular HVAC tune-ups. Replace or wash the air filter every 6–12 months, clear the condensate drain annually, and check for debris around the coils. We recommend a yearly professional inspection to clean the internal coil, verify refrigerant pressures, and recalibrate controls. With routine care, leading brands last 10–15 years and often carry 5-year parts warranties.

Will installing a dehumidifier reduce my energy bills and improve indoor air quality?

Yes. Lower humidity lets you raise the thermostat by 2–3 °F while feeling just as cool, cutting A/C run time and saving up to 10 % on cooling costs. By removing excess moisture, the unit also decreases the likelihood of mold spores, bacterial growth, and airborne allergens, leading to cleaner, healthier air. Many homeowners notice fewer musty smells and less dust within the first week of operation.
