"Rob from Goldens Bridge Plumbing makes you believe in “professionals” again. Two days ago I discovered that my hot water tank was leaking rusty water and overall was in a terrible condition and needed to be replaced instantly. A day later all was taken care of - it took Rob exactly 2 hours (as estimated) - very competent plumber - 1st class customer service, I absolutely can recommend him and his team."

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!"

"August 26 called JSP out to check on my xtrol pressure water tank because it was making a clicking noise that was coming from the power switch. Came out same day said the bladder ruptured would need a new tank. I agreed because the tank was 12 years old. Installed was a flex lite tank which he said was better. I'm a senior and a widow took his word for it. I paid $2172.66. It was not itemized. He gave me a $50 discount. He told me I would get water bursts for a while coming from faucets. Well he was right, however I lost pressure in my kitchen and bathroom faucets and the toilet was rumbling when filling and flushed. I called them out to check. He did not go under the sinks to clear the lines, instead he said it must be your faucets. He quoted me a price of $1303.48 for kitchen faucet if they picked it out fully installed or $756 if I bought the faucet myself. 3 strikes your out. Didnt fix problem. Found out I was over charged for flex tank $1200 instead."
