"The latest visit diagnosed a failed ignition valve which needed to be ordered and replaced. They arrived promptly, assessed, diagnosed and ordered the parts immediately. It only took a few days for the parts to arrive and they were able to schedule me in for the service call. The first technician was able to maintain the ignition valve until the new part was available, which was directly responsible for heating my home. The second technician installed the part and was able to assist me in some technical updates on the app and digital thermostats. I learned so much from Michael and appreciated his knowledge and patience. He also fixed a safety issue on the second level and adjusted the air flow for the system. The system sounds so much quieter. It was a warranty issue with no cost."

FAQs for central humidifier installation and replacement projects in Alpharetta, GA

Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.

With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.

It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.

Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.

If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
