"Fresh Air was a pleasure to work with. They were very quick to communicate with us about our needs and sent someone out to look at our geothermal unit a few days later. He was able to walk us through what he was doing and helped explain a lot to us. He was very patient and provided a lot of education. Overall, just great to work with. We bought a maintenance package from them too."

"Fantastic job installing my new water heater. The employees at Anton’s are efficient, professional and really likable people. They arrived on time and got the job done effortlessly. I also loved how they treated my home like it was their own by making sure nothing was damaged or ruined. They cleaned up everything and it didn’t even look like they had been here. I give Anton’s an A+ for the installation of my water heater."

"Sam was great. Had a extremely dirty system that would not function correctly or blow cold air. Had High Ridge Heating and Cooling here as he has done work before for me and parents. He took one look and stated we needed to replace entire a/c furnace unit for $3100. Told us it would cost about the same to clean. No way I could afford that so went on Angie's List to find someone and read Sam's review's. He came out and told me the cost at $425 to clean. Which was fantastic. He spent about 2 1/2 to 3 hours and did a wonderful job. Ended up paying total $625 once he was done and asked me before doing anything additional that would cost more. Also since our unit didn't have valves on system to reuse our refrigerant he had to put new in which was part of price increase. Sam, thanks so mich for not trying to take advantage."

"Our A/C failed during a very hot spell in June 2018 in St. Louis. Many service providers we called would not come. We called Vitt and told Jeff, the scheduler, about our problem: we had an old furnace (>50 years old) and had the blower motor rebuilt recently by Commercial Electric. Jeff gave us his cell phone number should we decide to go with Vitt. When I had the blower motor fixed, it was in the trunk of my car. I called Jeff and he sent Vic out that day. Vic and Dave came and removed the blower motor from the car and carried it into the basement. The J box was missing from the motor, and the wires leading to it had been cut too short. Vic spoke to Commercial Electric to confirm the correct approach to fixing the wiring. He drilled a new hole to compensate for the shortened wires and moved the capacitor to protect it from touching the filters in the furnace. He checked the relay box and made sure that the furnace breaker was working. After the A/C was successfully turned on, Vic and Dave checked the condenser for heat and then hosed it off. Both men were polite and listened to my information on the history of the furnace and its problems. They asked me appropriate questions about previous service companies. They were patient about my concerns and knowledgeable regarding older furnaces. The bill was reasonable for service provided by 2 men."

"Fantastic!! We had never had our ducts cleaned or sanitized. To my knowledge it was the first time ever and our house is 24yrs old. I can breathe again and the dust that is normally there 3 days after cleaning is gone. Nothing like before! The man explained all of my options clearly and did an amazing job. It was alot of work since we had just about everything done except the dryer vent because it is brand new. Kevin was on his own for the day as his helper was sick and he still had a good attitude and did a spectacular job. Didn't leave a mess either and cleaned up great before he was finished!"

FAQs for central humidifier installation and replacement projects in Wentzville, 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.
