"We recently had our HVAC system replaced by CoolRay Heating and Air and were extremely pleased with the entire experience. Mike Ritchey, our sales representative, conducted a thorough evaluation of our existing system and clearly presented several replacement options tailored to our needs. He was knowledgeable, responsive, and worked diligently to provide a competitive and fair price. The installation was led by Rollin Tappin, who, along with his team, demonstrated professionalism and care throughout the process. They completed the work safely, efficiently, and with great attention to detail. The new system is functioning perfectly, and we greatly appreciate the high level of service delivered by both Mike and Rollin. We would confidently recommend CoolRay Heating and Air to anyone in need of HVAC services."

"We had a full HVAC system replacement for both floors of our home, and we are truly grateful for the service we received from Weather Masters. From the beginning, the owner was understanding of our situation and worked with us on the pricing in a way that no other company was willing to do. He adjusted the cost significantly — almost as if we were paying cash — which meant so much to our family during a stressful time. The installation was done professionally and efficiently, and the team was respectful and organized throughout the entire process. It’s rare to find a company that combines professionalism with genuine care for their customers. We truly appreciate Weather Masters and highly recommend them. Thank you again for helping our family."

"The technician was very nice and did a great job. Old water heater was removed and the new one installed. The technician showed me his work and explained what he had done. I recommend Moncrief."

"I gave Cool Air Mechanical a call after reading their good reviews online. Every one I dealt with on the phone was very helpful, and were able to get help out to us ASAP. Jerry C. who came out was very knowledgeable, friendly, and professional, and was able to diagnose our issue quickly and provided great options and advice. He returned with the replacement part and repaired our unit very quickly. I will definitely be calling on them, and Jerry specifically, for any work on our system in the future."

"Wonderfully! I'm so glad I reached out to them. I was worried when my home warranty assigned me to them and I saw the reviews on Angie's List. They seem very hit or miss. Nate, however, was prompt and knowledgeable. He explained what issues I should be concerned about and what I shouldn't be concerned about. He even fixed an issue a top-rated company on Angie's List forgot to do (though they promised me they did. Sigh!). I really appreciated feeling heard and respected. I appreciated him going the extra mile. I may not be able to recommend the entire company, but I DEFINITELY recommend Nate! :)"

FAQs for central humidifier installation and replacement projects in Marietta, GA

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.
