"I posted I needed a window AC unit removed and this company was the only one to respond. The owners wife responded with in an hour, told me they would be at my house 3 days later. I responded, can you give me an estimate of how much it would cost. She responded, sir there is no charge, we just like helping out the community. I was shocked. Being on a fixed income. Craig arrived, removed the AC, and I started asking questions about mini split systems. He was here at least an hour explaining how they worked and my options. I have now ordered my new AC slash heatpump, to be installed. There was no pressure, just me asking questions and I loved what he had to say. Perfect gentleman."

"I have worked with Proactive before and they were excellent. This project called for removing of existing sinks and replacing them with under mounted sinks. The staff member in the office was going to speak to the owner to see if they were willing to install the under mounts, since they normally do not. But since I was a previous customer, the owner might reconsider. They never got back to me. I contacted Angie's List again and they set me up with someone different. He is coming next week to begin the project."

"East Coast Plumbing and Heating provided us with a great service on a big job of replacing our 30 years old furnace. Dylan was very accommodating and explained the process in a great detail. His estimate for the job was honest and fair. Dylan and his crew did the job in one day and did an excellent work for a reasonable price. We are very happy with this company and we will work with them in the future. I highly recommend East Coast Plumbing and Heating."

"It worked out okay, except that I would have anticipated, the cost just gets more. They always find those things, so it starts at $99 and end up spending $300 or $400. People tell me they always find mold inside your air duct, so they have to put a chemical. They call it a total cleaning as opposed to the regular cleaning which I paid for. What they did seemed to have worked. I have suspicions about when they find other things. "

FAQs for central humidifier installation and replacement projects in Alton Bay, NH

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.
