"I needed to replace my parents' 40 year old AC Condenser and coil, and replace it with something that worked with the new furnace my father got installed four years prior. They were able to do the work requested, and also offered to redo the furance installation as the previous company installed it right on the basement floor where any backup/water could possibly get into the system. They were very prompt and showed up on time/on schedule. They were very upfront about costs and pricing and there were no last-minute price changes or hidden fees, which I appreciate. Work was done well and they ensured that everything worked before leaving the job site. The gentlemen working were very professional and understanding. I highly recommend them for anyone looking to replace their HVAC or to correct work that was previously poorly done. "

"They were super helpful, they rushed the service. They picked uop the unit at night from the manufacturer. They went out of their way. The replacement units are working well and they were installed properly. I have been trusting their services and they have been working on two of my houses for around 20 years now."

"Called Sam on Friday for quote for water heater replacement. Said he could do Monday afternoon or Tuesday morning. Received call Monday morning to see if he could come on over to do replacement, what a pleasant surprise! Sam arrived shortly after with water heater we discussed & all supplies needed , no running around to pickup stuff. Job completed in timely manner. Old unit hauled off and job site all cleaned. That’s a big deal to me. Will not hesitate to recommend Liberty to friends & relatives ! Thanks Sam , Dave & Roxanne"

"Very well. There was no need to replace the toilet. All that was identified was that the brush that was stuck in the toilet was removed along with the flush. Cost us just $165 as opposed to then $225 quoted to replace the toilet and the cost of the toilet, which was $108 totaling $333. Saved $168."

"We have used this company for both rental and owner-occupied properties. They replaced the roof, gutters, and worked with the company to make sure that our awnings and other items were replaced. They also worked very well with our insurance company and we had no problems at all. Jacob made everything so easy that if we ever need anything else done and they can do it, they have the job."

FAQs for central humidifier installation and replacement projects in Saint Charles, 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.
