     Dear Mr. Weinstein,

    My experience with JW Plumbing has been exceptional from start to finish. A lot of prior research went into my ultimate decision to go with JW for my air conditioning needs. Josh Weinstein impressed me from the get-go with his honest and straight forward demeanor. Coupled with his competitive pricing and knowledgeable assessment of my situation, I was sold. That being said, the work that was done exceeded my expectations. The technician was efficient, focused, respectful and tidy. Two thumbs up for JW Plumbing!

    What is Central air conditioning?

    Central air conditioners and heat pumps are designed to cool the entire house. It employs the same types of components, materials, and systems as a refrigerator, including a refrigerant that changes from liquid to gas and back to liquid as it travels through a system of tubes and coils or fins that collect and give off heat.

    Two types of central air conditioners

    There are two types of central air conditioners: a split system or a packaged unit.

    a) Split-system

    In a split-system central air conditioner, an outdoor metal cabinet contains the condenser and compressor, and an indoor cabinet contains the evaporator. In many split-system air conditioners, this indoor cabinet also contains a furnace or an air handler. The air conditioner's evaporator coil is installed in the cabinet or main supply duct of this furnace or heat pump. If your home already has a furnace but no air conditioner, a split-system is the most economical central air conditioner to install. 

    a) Packaged central air conditioner

    In a packaged central air conditioner, the evaporator, condenser, and compressor are all located in one cabinet, usually placed on a roof or a concrete slab next to the house's foundation. Air supply and return ducts come from indoors through the home's exterior wall or roof to connect with the packaged air conditioner, usually located outdoors. Packaged air conditioners often include electric heating coils or a natural gas furnace. This combination of air conditioner and central heater eliminates the need for a separate furnace indoors. 

    Benefits of a central air-conditioning system

    Understanding the benefits of a central air-conditioning system

    Indoor comfort

    -Indoor comfort during warm weather – Central air conditioning helps keep your home cool and reduces humidity levels.

    Cleaner air

    - As your central air-conditioning system draws air out of the rooms in your house through return air ducts, the air is pulled through an air filter, which removes airborne particles such as dust and lint. Sophisticated filters, like those found in the Lennox Healthy Climate® purification systems, may remove microscopic pollutants, as well. The filtered air is then routed to air supply ductwork that carries it back to the rooms.

    Quieter operation

    Because the compressor-bearing unit is located outside the home, its operation's indoor noise level is much lower than that of a free-standing air- conditioning unit. 

    What is the difference between VRV & VRF systems
    VRV is short for Variable Refrigerant Volume. VRF stands for Variable Refrigerant Flow. The fact is, these are two different names for the same basic technology. Why are there two names for the same thing? Back in 1982, Daikin Industries invented the first Variable Refrigerant Volume system and trademarked the term VRV. When other companies came along later and developed systems using similar technology, they had to call it something else. That’s where the term Variable Refrigerant Flow came from.
