"Company is professional. Pricey compared to alternatives. Said they could deal with plumbing and HVAC, but the tech that showed up, while nice, knew little about plumbing. Did clean water out of furnace lines, but have had this done before paying about a third of the money."

"Dwight installed a tankless water heater and water softner for us. He did a quality job and was some $1,500 cheaper than the highest bidder for essentially comparable equipment."

"Computer had been acting up for a while but I kept putting off getting it fixed.  After reading all the great reviews, I decided to give N.A.T.S. a call.  So glad I did.   Jim was able to resolve all my problems remotely - no drop off or pick up necessary - so convenient!  I feel like I have a brand new computer, it runs so well and FAST too.  I couldn't be happier and wouldn't hesitate to use his services again.  My only regret is that I didn't call him sooner.

"Choice was fast, efficient, and kept me posted on the progress of the claim. Although the water leak issue was discovered on a Friday, they had a plumber there to investigate by Saturday morning. When it was determined that the 20+ year old heater needed to be replaced, the replacement ordered, on-site, and installed by Wednesday morning. I am glad that we opted for the Choice Ultimate plan as other than the initial $65 service fee, all but one $50 ancillary expense was covered."

FAQs for central humidifier installation and replacement projects in Columbia, MO

A crawl space dehumidifier is a worthwhile investment, particularly in humid climates or if you've noticed musty odors, mold growth, or wood deterioration. Though costs range from $3,000 to $9,200, this investment helps prevent structural damage that could require far more expensive repairs later. Beyond structural protection, a properly dehumidified crawl space contributes to better overall indoor air quality and may reduce allergens throughout your home. Consider having a professional assessment to determine if your specific situation warrants this investment.

Addressing crawl space moisture effectively often requires a combination of solutions. A complete approach includes encapsulation plus dehumidifier installation. For minor moisture issues, a basic dehumidifier starting at $1,500 may suffice, while severe problems in larger spaces could require systems costing up to $14,000. The most effective moisture control strategy depends on your specific conditions, making a professional assessment valuable for determining the most cost-effective approach for your situation.

For a crawl space measuring 1,500 square feet, you'll need a dehumidifier with a daily capacity of 30 to 50 pints, with unit costs ranging from $150 to $600. Your local climate and existing moisture levels may necessitate adjusting this capacity—homes in particularly humid regions might benefit from higher-capacity units. Professional installers can measure your specific humidity conditions and recommend equipment that is appropriately sized, balancing initial cost with operating efficiency for your unique situation.

Crawl space dehumidifiers add $300 to $500 to your annual electricity expenses when operating continuously. Energy-efficient models reduce this consumption by roughly 15 to 30% compared to standard units. Most contemporary dehumidifiers feature humidity sensors that automatically cycle operation based on current conditions, helping manage energy usage. Proper crawl space encapsulation significantly improves efficiency by creating a controlled environment that requires less dehumidifier runtime, thereby reducing ongoing electricity costs.
