"This is my second experience with Joyce Plumbing and Heating. The first time was a new hot water tank. When you have your local city inspector tell you during inspection of the tank installation that "oh, Joyce did it? Then I don't even need to look at the installation...". That was a ringing endorsement!! We then moved to a mini-split heating/cooling system for our house. These guys were just terrific. We had 3 units put into our house and the team worked flawlessly. From Will (our super human sales guy) to Tina in the Joyce P&H office (customer care) to Calvin and his team, we were very well treated, on time and under budget. I highly recommend Joyce Plumbing and Heating and we will be using them again. You should to!!"

"Gerry was running late for my appointment to clean and inspect two A/C units. He called to let me know . That's a real big plus.... He didn't waste my time. Once he arrived , the work was done quietly , quickly and at what I thought was a fair price. I will call him if I need service in the future."

"Great, as always. Sila is outstanding. We have a service contract with them for our furnace and AC and they keep them in tip-top shape. And when we have an urgent or emergency situation (heating, cooling, plumbing, electrical), they're who we call."

"The service technician Victor arrived on time and politely introduced himself. Prior to commencing work he inspected the work area (installation and clearances etc). He explained the house heating would be off as he cleaned filters etc. After cleaning/adjustment/testing was conducted, he went over the test results printout with me. All good and nothing required further work."

"Our daughter and her husband are living out of the country, temporarily. When their leasees said the furnace was blowing cold air, we wanted the repair done quickly and at a good price. Unique Indoor Comfort Heating & Cooling responded right away and came to the property the same day we called. Very professional! "

"The technician/plumber didn't get the job done at all. He ended up breaking the shower valve and ended up placing a stopper on the line to prevent water leakage. In the process, he ended up taking 5-6 hours for a job that was finished by another plumbing company in 2-3 hours. It was a waste of my money as Village Home Services billed me $560, fixed nothing and broke the valve. Furthermore, their manager/owner asked me for another $2000 for them to come back and repair the damage they created. I got this job done for $800 from another plumbing company based out of Tyngsboro. I DO NOT RECOMMEND VILLAGE SERVICES. "

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