"Shawn performed the annual heating inspection for our furnace/oil tank. As always he was very quick, and took extra time to walk me through the piping of our different heating zone. Highly recommend Genove Oil, they are providing stellar service and with employees like Shawn you are in very good hands."

"The project went well. There were some leaks after the initial installation, but these were fixed before any damage was done to the ceiling and wood flooring."

"It was quite a surprise to find black mold growing in our mini-split heat-pump/ac units over the weekend! The situation was quite dire with the system emitting a bad smell and the fact that I have asthma and mold allergies which posed a serious health risk! After being told by the company that originally installed the system, “We don’t provide deep cleaning service for these units, try looking on Angie’s List (boo on Sila!)” I landed here. While other companies did respond to my bid, Atlantic Heating and Air Conditioning was the most responsive and was able to send out a team on one day’s notice (the wait for other service providers was up to three weeks!). The tech team, Josh and Zack, arrived on time and called me 1/2 before arrival as promised. They were very respectful, kept a clean work space and (since we are in the middle of a pandemic) wore masks and were very careful about the usual COVID protocols. The four units in our home are now SPARKLING CLEAN! We are 110% pleased with this job!! We will hire Atlantic as need be in the future for our heating and cooling needs. I have given up on the company that originally installed the units and will post a truthful review about them in an appropriate space online. I would definitely recommend Atlantic to family and friends. (photos attached to this review show one of the units before cleaning - did not think to take after pictures. Suffice it to say, no more mold:)"

"The install of the equipment it self was done in 2 days and very well done, however there was an issue with getting power to the thermostat. To ARS’s credit they worked as fast as possible to resolve the issue at no additional charge and once the part was installed the system worked flawlessly. Even though it did take another 5 or so days to complete I appreciate that they did not let this slip through the cracks and stayed on it until the job was done. The teams were all very knowledgeable and professional. Would recommend."

FAQs for central humidifier installation and replacement projects in Ashland, MA

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.
