"Rene and Maurico installed a new air conditioning unit in my home. They negotiated fairly and were responsive to my questions. A team of five arrived for the installation. They worked together like a well tuned machine. Everyone knew what they had to do and when to do it. There were no mistakes. They were here by 8:00 am and were finished by 4:30. They answered all my questioned and responded to my phone calls. They were polite and respectful. They cleaned up after themselves and left nothing damaged. More companies should operate like them. I would highly recommend them"

All Weather Heating & Cooling has been serving Nassau & Suffolk County of Long Island since 1969. We are now celebrating 56 years of exceeding customer expectations. All Weather provides sales, installation, service and maintenance of residential and commercial heating, air conditioning & water filtration systems.

"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"

We are a family owned and operated business with several years of HVAC experience. We pride ourselves on providing an honest and accurate quote and stand behind our work. We have outstanding ratings and provide superior customer service. Feel free to check us out and give us a call for more information.

"TLDR: safe, thorough, educational. 10/10 would call again. - My in-unit residential heater has been rattling and the filter light has been going off since I moved in (2 years). I've taken it apart (as much as I could) to do superficial cleanings, but to be safe I asked my landlord if I could find a Rinnai-certified technician to complete a professional servicing. I found Mazgan on Google and chose them due to their 4.7 rating. My landlord's initial concerns with outsourcing from the super was that companies tend to tack on hidden fees/charges. Mazgan did not do this. In advance of our appointment, Mazgan assured me that they were only booking me for a professional servicing appointment (which included opening up the unit, completing a comprehensive cleaning, and diagnostic), and that any issues found would not be addressed in that appointment but rather a 2nd appointment would be recommended if necessary. Thankfully, nothing was wrong with the unit (besides the fact that it has literally never been cleaned 🙃). Zaki, the technician, was extremely thorough. He cleaned the unit for nearly 2 hours, was very quiet and gave me a heads up when something would be noisy (which enabled me to work-from-home in peace), showed me photos of how clogged the vents were with dust/grime, and provided a lengthly and clear explanation of how the machine works and the importance of cleaning/how accidents can happen if not. They showed up when they said, charged what they said, and completed what they said. First things I did once Zaki left were to save Mazgan's number, purchase a carbon monoxide detector, and leave this review."

FAQs for central humidifier installation and replacement projects in Franklin Square, 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.
