"I have used this company before for plumbing repairs, and I have to agree with many of the reviews. They were prompt, professional and I thought they charged a reasonable fee. So when I decided to install a water softener in my home, I immediately thought of them and asked them for a price estimate. I was told that they charged $69. When I balked at that, they said they would waive the fee and send someone out. I thought that was really nice of them to do that and was looking forward to getting their estimate. I was going to supply the water softener myself, so all I needed was to have them install it. I am fairly handy around the house myself and I knew that this wasn't going to take much more than a hour or so of their time and a few parts. It was not a big job. I was absolutely floored when I go their estimate. They wanted $4,243 for installation only. I find it hard to believe that they would want so much money for so little. I truly felt like they were trying to rip me off. I found a licensed plumber on Angis's List who did the job for $600, which as about what I had estimated the job would cost. I was extremely disappointed in CM Heating's highly overpriced estimate for a simple job. It certainly didn't inspire confidence in the company. They have lost my business forever."

Central humidifier installations and replacements FAQs

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.
