FAQs
Why should I add a whole-house dehumidifier to my HVAC system in McDonald?
McDonald’s warm, humid summers can push indoor humidity well above the recommended 30–50% range. Excess moisture encourages mold, mildew, dust mites, and musty odors while making your air conditioner work harder. A properly sized, professionally installed whole-house dehumidifier removes this excess moisture as air passes through your HVAC ductwork, improving comfort, protecting furnishings and structural components from moisture damage, and lowering the load on your AC so it can cool more efficiently.
How do I know what size dehumidifier my home needs?
Sizing is based on square footage, average summertime humidity levels, the number of occupants, and specific problem areas such as basements or crawlspaces. During a free in-home assessment, our NATE-certified technician measures these factors and performs a Manual J load calculation. This ensures the unit’s capacity (measured in pints of moisture removed per day) matches your home’s actual moisture load so you get optimal performance without wasting energy or short-cycling the equipment.
Can a dehumidifier be installed on my existing furnace and air conditioner?
Yes. Whole-home dehumidifiers are designed to integrate with most forced-air HVAC systems. We tie the unit into the return ductwork, add a dedicated drain line for condensate removal, and wire the controller to your thermostat or a stand-alone humidistat. Because it shares the HVAC blower, you benefit from balanced air circulation throughout the home. If your system is older, we inspect ductwork and blower capacity first to confirm compatibility and recommend any minor upgrades needed.
How long does a professional dehumidifier installation typically take in McDonald?
Most installations are completed in half a day—about 3 to 5 hours—depending on duct accessibility and whether a new electrical circuit or condensate pump is required. We schedule appointments at your convenience, protect floors and furnishings, test the unit after installation, and walk you through operating controls before we leave. Larger homes with multiple HVAC zones may take a bit longer if more than one unit is being installed.
What maintenance does a whole-home dehumidifier require after installation?
Unlike portable units, whole-home models need only light maintenance. Replace or rinse the unit’s internal air filter every 6–12 months (or as indicated by the manufacturer), keep the condensate line clear, and schedule an annual HVAC tune-up so our technician can clean the dehumidifier coil, check refrigerant charge, and calibrate the humidistat. Staying on top of these tasks keeps efficiency high and prevents mold growth inside the unit.
Will a dehumidifier increase my energy bills?
A dehumidifier uses electricity, but most homeowners see little or no net increase in monthly costs. By reducing indoor humidity, the unit allows you to set the thermostat 2–4°F higher without sacrificing comfort, which often lowers air-conditioning runtime. In many McDonald homes we service, the energy the dehumidifier uses is offset by AC savings and by preventing moisture-related repairs, making it a cost-effective comfort upgrade.
