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!"

Solar Panels questions, answered by experts

While solar panels can be a great investment, they aren’t ideal for every roof. For example, some roofs, especially older or structurally weak ones, may struggle to support the added weight, leading to potential damage. Roofs with complex designs, obstructions, or limited sunlight exposure might not provide optimal conditions for solar energy production. Consider these downsides when determining if solar panel installation costs are worth it.

Yes, a solar panel can power a TV without a battery, but only if the sun is shining and the panel is generating enough energy. Your solar panel and TV must have the same voltage, and you should install a charge controller and inverter between them so power surges don’t destroy your TV. To watch TV at night, in the early morning and late afternoon, and on cloudy days, your home must be tied to the power grid.

The actual time it takes to construct the solar farm is relatively short, taking between 2 and 4 months on average. That timeline is dependent on site conditions, crew size, and the overall size of the solar farm.

However, the time it takes to get the ball rolling is significantly longer, ranging from 3 to 5 years. With a project of this scale, you’ll need to obtain all of the proper permits and approvals to start breaking ground, and depending on your location, that could be an extended process.

Professionals use the same methods to install solar shingles that they do for asphalt shingles, so you’ll often see a similar installation timeline of one to two days. The amount of time required will depend on the size and slope of your roof and the number of shingles installed. Weather conditions can delay installation, as working on a roof is unsafe during high winds or heavy rain.

Yes, you should tell your home insurance company about your solar panels. Even if you believe they’re covered by your existing policy, installing a solar panel system is a significant change to your home. This can affect coverage and premiums. By discussing your new solar panel installation with your insurance provider, you can be sure you have enough coverage and that the policy completely covers the panels against damage.
