"The person that showed up is the owner. He diagnosed the problem with my central air conditioning system, was a clogged filter due to sanding spackle. Could have charged the system or fed me a bunch of lies but instead was perfectly honest, charged me an inspection fee only and buttoned everything up. I was shocked. Great guy and knows his stuff. Would definitely recommend him."

"We were desperate to find someone to repair our central air conditioning unit. We were not able to move into the house and everyone that we called was not able to accommodate us because of the recent heat wave. All Weather was able to get a technician to us within 2 days. Nuri was amazing and showed my husband how everything worked and what repairs needed to be done. By the time he left, we had a cool house and were able to set up our movers. Thanks to Angie’s list, I found a reputable company that was reliable and efficient. We can rest easy! Thank you!!!"

"The entire experience from the discussions with the company rep Scott O, to the completion of the installation was excellent. The installers were courteous, knowledgeable and efficient. The Mitsubishi unit itself is an excellent product. Cools quickly, quietly, and is multifunctional. The installers Brian and Moses did the job in a courteous, knowledgeable and efficient manner. All stages of the job went smoothly. Functions of the unit and use of the remote were explained thoroughly and a booklet was provided that reinforces the information. Cleanup was excellently done. I am very pleased with the communication with Scot O choosing the product to be installed, getting questions answered as well as with the knowledgeable, courteous and efficient installers. I highly recommend Elm Air Conditioning."

Customers say: Quick response

"Ray was friendly and very professional and you can tell immediately that he was very customer oriented. As far as prices go, he was more than fair compared to the other bids. As a matter of fact I expanded the scope of his work to include a new water heater too. All the equipment supplied was 100% new, still in the factory cartons and the installation work was TOP QUALITY. Ray not only sold me the job but he did the installation too. He and partner Ken, and their assistant (3 man crew total) worked very professionally and effectively. Needless to say I HIGHLY RECOMMEND THEM."

FAQs for central humidifier installation and replacement projects in Islip, NY

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.
