"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!"

FAQs for radiant floor heating system installation projects in West Islip, NY

In new construction, installing radiant floor heating costs between $19,000 and $48,000. The price depends on factors such as the heating system type, flooring material, and square footage. Since there's no existing flooring or wall to work around, the installation is more straightforward, reducing labor costs and improving project efficiency.

Radiant floor heating warms rooms by circulating heated water beneath the flooring, while baseboard heating supplies warmth through units installed along the lower wall portions. Radiant flooring systems deliver even and consistent heat, whereas baseboard units generate gradients of warmth. Radiant floor heating also reduces heat loss, making your home more energy efficient.

Tile and stone are the best choices for radiant heating because they transfer heat rapidly and efficiently. These materials warm the room quickly, ensuring optimal comfort. While wood, laminate, vinyl, carpet, and rubber are acceptable alternatives, they conduct heat slower and require extra energy to achieve the same temperature levels.

Radiant floor heating heats an entire house only when every room and area is outfitted with the system. Installing radiant heating across all of your living spaces ensures complete and consistent warmth, eliminating cold spots while enhancing energy efficiency. Installing a whole-home system provides even warmth, eliminating reliance on forced-air systems.

In-floor heating systems deliver long-lasting performance, with tubing and coils lasting 20 to 35 years and boilers operating for 15 to 20 years. Routine maintenance and prompt repairs ensure your heating system reaches its maximum lifespan. A properly installed system provides reliable warmth over decades, making it a durable long-term investment in home comfort.

Radiant floor heating prevents mold growth by actively reducing moisture beneath the flooring. It maintains warm surfaces that dry excess water and lower condensation, which minimizes the conditions needed for mold to thrive. This efficient control of humidity results in a healthier environment indoors, ensuring that moisture issues are kept well below harmful levels.
