"They are supposed to come tomorrow, they agreed on that. They called and told me that the job is too small and they refused to do the job. Meanwhile I described the job to the woman, the dimensions and the specifics and she agreed but still cancelled it."

All Weather Heating & Cooling has been serving Nassau & Suffolk County of Long Island since 1969. We are now celebrating 54 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!"

"I never leave bad reviews but feel compelled to warn people not to use this man's service. The most unprofessional, short tempered and hostile man. I am a young mother with a 3 month old infant, so getting our hvac fixed is crucial. Vinny canceled on us last minute and rescheduled twice, he bad mouthed other companies who had worked on our system previously, he told us to run our own wires, and then called my father in law stupid for doing it wrong. When I interjected saying that that wasn't very nice and asked my father if we should call someone else, he became irate, yelled at me for saying something, said i ?should mind my business? in my own home, raised his voice loud enough to startle my infant and made him cry, said he ?should have pushed us down the stairs?, and stormed out of the house like a disgruntled prima-donna. The whole situation left me and my baby rattled. This man thinks that the demand for his trade entitles him to speak down to and mistreat customers.Go elsewhere."

Heating and Air Conditioning questions, answered by experts

If refrigerant levels are low, it can cause the evaporator coil to freeze up. Low freon causes a drop in pressure, which will make the coil too cold and cause moisture to freeze on the coil. Your system may be low on refrigerant because of a leak. 

Make sure to have maintenance performed twice a year, and contact your local HVAC technician if you suspect your system has low freon levels.

Capacitors are the most frequent part of an HVAC system to experience failure. These components are crucial for starting the motors that power the fans and compressor, but over time, they may become worn or fail due to electrical surges or regular wear and tear. When capacitors malfunction, HVAC systems may experience decreased heating or cooling efficiency, or even total system failure. Replacement or maintenance of capacitors is a common requirement for the optimal functioning of HVAC systems.

On a summer day, expect your AC to run between 12 and 16 hours. However, this time frame depends on just how hot it is outside and the comfortable temperature you’re hoping to maintain indoors. Assuming the size of your AC is appropriate for the space you’re trying to cool, it shouldn’t be a problem for it to work this many hours.

Yes, ductless AC adds value to your home. Fixing or replacing traditional ductwork is an incredibly expensive and daunting prospect. Traditional ducts can be noisy and temperamental, with the potential for unwanted guests like hornets and rodents. Ductless mini-splits eliminate a major hassle and expense, so they can increase a home's value.

If your whole house is cold that’s one thing, but what if you only have a few rooms that are cold? First, you need to determine why this may be happening. A good place to start is to investigate the potential causes listed in this article—heat transfer, airflow, thermostat problems, humidity, and insulation. Once you’ve narrowed down the issue, you’d apply the same principles to the cold rooms as you would to the entire home.
