"First, Schaal really needs to add "plumbing" to their catchy commercial jingle because whenever I'd tell someone who I'd called to come and fix my leaky toilet they'd say "They do plumbing too?" Yes, they do. Second, I have to mention Deb, who answered the phone when I called to schedule my appointment, has to be one of the best customer-service people I've dealt with. She was extremely friendly and helpful, so compliments to her.    The reason for my call was a toilet leaking into my basement when flushed. Also had the valve replaced as it sprayed water when flushed. Plumber arrived on time (a bit early even), explained what was possible that he might uncover (my house was built in 1940 so I knew other problems could be uncovered) and got the work completed in under an hour. Luckily he didn't uncover anything more than the basics - wax ring replacement, flapper/valve replacement. The price for the work done seemed reasonable I suppose, but that's one of those things I'm never sure of. When your toilet is leaking into your basement you don't want to get a bunch of estimates, you just want it fixed so you get the first people available out. Overall completely satisfied with the work and would certainly use Schaal again in the future."

FAQs for central humidifier installation and replacement projects in Knoxville, IA

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.
