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!"

"Rich told us it would be months before windows were installed due to supply shortages. Sure enough it took a few months but was it worth the wait. The new windows block out noise and the summer heat. I don't even have blinds on them anymore since I enjoy looking outside. They redid the stucco trim around them. My house looks brand new. Worth the money I spent. Better news, they are lifetime guaranteed so I won't need to do this again. Thanks Superior!"

Water Heaters questions, answered by experts

A leaking water heater could potentially last for a few weeks or months before you need to repair it. However, it's not advisable to wait too long. Once your water heater starts leaking, it's likely that the underlying cause of the leak is getting worse as time goes on. Without immediate repair, your water heater could fail. Instead of using a leaky water heater, you should turn it off and call a pro to fix it.

Water heater replacement costs around $1,300, but a total install will depend on a few factors. Solar heaters can cost upward of $3,700, while conventional gas heaters may cost less than $1,000. Tankless water heaters, common in apartments and homes without much space, cost around $2,600 to install. Expect the cost to increase significantly if new plumbing is required, or if there is damage from a previous water heater malfunctioning. 

A tankless water heater can last up to 20 years, but just how long your tankless water heater lasts depends on how much water you use, how well you maintain your water heater, and the water hardness level in your area. A unit that constantly has mineral buildup from hard water may have a shorter life span.

Most hot water heater manufacturers recommend replacing the anode rod about once every three to five years. Anode rods sacrifice themselves by collecting iron, limestone, and other minerals that would otherwise corrode your hot water heater tank. This abuse wears them out long before your water heater does. Check the rod when you remove it and replace it if more than 50% of the metal has been consumed. Check the rod more frequently if you have hard water or use a water softener. 

If you have a tank-type electric water heater, it runs regularly to keep the water at the desired temperature. If you live in a home where you don’t use much hot water, it could seem wasteful to run power to heat water that you’re using infrequently. You could save some power by using a smaller tank, insulating the tank, or lowering the temperature of the water heater.
