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!"

"Efficient and clear process, nice crew, quick and clean execution. It would score 4.5 as there were a couple of opportunities for improvement identified (including surprising problems with running a communication cable, and a trivial unnoticed misconnection sorted out the next day by a dedicated technical help call), but overall an outstanding service."

Solar Panels questions, answered by experts

Correctly installed solar panels will increase the value of your home by around 4%. With the median home sale set at $429,000, this means an increase of approximately $17,000. Many home buyers want to switch to solar, making homes that have this feature tempting and worth the investment compared to homes that are only tied to the grid. Other solar features, like a shed with solar panels, will also boost your home’s value.

Installing solar panels is worth it if you’re frustrated with paying high utility bills, live in a sunny location, and qualify for tax credits and incentives. Most homeowners cut between $650 and $1,500 from their utility bills each year by installing solar panels. Over the course of your panel’s warranty, you could save anywhere from $16,300 to $37,500, though those in sunny areas with high energy costs could save more than $100,000.

On average, a typical fridge uses 115 kWh per month. With eight hours of sunlight per day, a 100-watt solar panel can produce 30 kWh per month. This means you’ll need at least four dedicated panels to power the refrigerator with solar energy. Consult with a solar power specialist to get a more accurate estimate.

Removing solar panels can be straightforward, but it’s not necessarily a simple process. Your contractor needs to prevent damage—not only to your panels but also to your roof and electrical system. Many systems are wired into the main electrical grid, and you’ll need to hire a licensed electrician to disconnect it.

Ideally, you want to place them facing true south. This is different from what a compass shows, which is called the magnetic south. You can find true south by using an online calculator as long as you know the longitude and latitude of your property. Solar panel placement is key to maximizing the energy you generate, so this is an important step.
