Brands we working with

  • “Erez and his team are truly the best. They put clients first and always deliver as promised. He discovered that my compressor was dead due to my former HVAC company never performing the actual maintenance, and he rushed ordered the part and installed the next day. I can honestly say they have saved my business on a few occasions and I can't wait until we install a new exhaust/ventilation system. Very high quality of work, and they are straightforward, honest, and consistent every time.” -Jonathan

  • “Ultimate Air Conditioning came out to fix our commercial refrigerator and did a wonderful job. The air compressor was clogged and over heated. Their technician restarted the fan for the kitchen and now it works perfectly. Can recommend them highly to everyone for speed and technical knowledge.” -Mark

  • “I had a great experience with Ultimate Air Conditioning! I just moved to a new home and seems the previous owner haven't cleaned the air ducts system in a very long time. The interior temperature was never what we wanted it to be. They cleaned our furnace unit and the air duct pipes. We also decided to install a new thermometer. Great experience, professionalism, and now the house is comfortable at the right temperature.” -Bethany

Why do we use it?

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).

Where can I get some?

There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don’t look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn’t anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc.

Where does it come from?

Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of “de Finibus Bonorum et Malorum” (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, “Lorem ipsum dolor sit amet..”, comes from a line in section 1.10.32.
