"Worst service I’ve ever have experienced. They wanted to sell me the product, never told me that there was an early termination fee and another penalty for an initial offer they gave me. Had double charges every month, once for the oil they provided (which they never told me they were going to provide before coming. They just came without my knowledge and then I find a high amount bill) and another for an “automatic payment” for 500 that they never could explain. The didn’t even fix this issue and it kept happening every month even after I cancelled the service. Then having to call them is a hastié for the refund of the 500. Stay away of this company"

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!"

Humidifier Repair questions, answered by experts

While you’re busy swapping out that old compressor, now is a great time to have your furnace cleaned and serviced , especially if your home is older and your heating system is as old as your AC unit. Likewise, it’s a good idea to clean your air ducts to ensure air flows properly through the house.

During your HVAC preseason maintenance call, your contractor will inspect the system for any problems and make small adjustments for better efficiency. Tasks include, though are not limited to: 

  • Changing filters

  • Checking the thermostat

  • Clearing away dust and debris

  • Checking for mold

  • Inspecting electrical elements

  • Inspecting condensate lines and drain

  • Cleaning evaporator coils

  • Ensuring ignition function

While you can do some of these services yourself, hiring a professional to keep HVAC equipment running can be helpful. These experts know what to look for and may be able to spot potential issues before they become problems. Many HVAC companies offer annual maintenance plans.

Air conditioners and dehumidifiers are actually quite similar, though they perform different jobs. Dehumidifiers reduce moisture in the air, while air conditioners work to cool the home. A good central AC unit will naturally perform a certain level of dehumidification due to its design, but it will not be able to handle excessive levels of moisture.

The average whole-house humidifier might last 10-15 years. Regular maintenance can help the unit last longer. Keep in mind that houses in dry climates use humidifiers more frequently, which may exacerbate wear and tear. A professional can help you determine if it’s time for a replacement. 

No, air purifiers neither cause dry air nor increase the home's humidity levels. They remove allergens and dust but don't alter the water content in indoor air. However, because some air purifiers move large volumes of air, the areas immediately surrounding a portable unit can feel cooler and dryer than the rest of the home.
