The Evolution of Air Conditioning

Dr John Goorie’s Air Conditioning Invention

Air conditioning is something that can be found in about 100 million homes across the USA but that was not always the case.

There was a time in our history that people were very uncomfortable when the temperature went up due to air conditioning not yet being invented or not yet developed to the point where it could be easily installed into someone’s home.

Let’s take a look at the evolution of the air conditioner:

1840 – A Floridan named Dr John Goorie, proposed that a cooler environment would help decrease disease and make patients more comfortable in their hospital rooms. He tried to accomplish this by having ice shipped in from frozen lakes and streams up north but that became too expensive. Next, he started fiddling around with the concept of an artificial cooling system.

1851 – Dr John Goorie secured a patent for a compressor that was powered by a horse, wind and utilized water or steam. Although his financial backer died before this invention could come to market, the foundation for modern style air and refrigeration was set.

1904 – Willis H Carrier filed a patent for an apparatus for treating air. His system controlled humidity by using cooling coils. He eventually left his job and with six other engineers formed Carrier Engineering Corporation.

1904 – The first time the public was exposed to the comforts of having cooled air was at the St Louis World Fair. Organizers for the fair used mechanical refrigeration to cool the 1,000-seat auditorium at the Missouri State Building.

1922 – 1925 – The first early public cooling systems were in the movie theater where crowds would flock to watch movies while sitting in the comfort of cool air. These early units were heating systems modified with refrigeration equipment (huge sized systems) that cooled to some degree but not evenly. Some areas of the room would be hot and some cold.

1929 – Frigidaire came up with a split level unit for home use but still it was too expensive, heavy and required a separate condensing unit.

1930 – 1931 – General Electric produced 32 prototypes of a room cooler that was self contained which was an improvement on Frigidaire’s model from the year before.

1932 – H.H. Schultz and J.Q. Sherman built units that could fit on a window ledge but were too expensive so not many were purchased.

1947 – Engineer Henry Galson developed a better more compact ac unit that was spin off of the window ledge unit but was less expensive so he set up production lines with multiple manufacturers and for the first time the public could enjoy the comfort of cool air without having to make expensive changes to their homes.

1960 – Most new homes were being equipped with central air conditioning and window units were very affordable.

1970 – After the energy crisis hit, new laws were passed to reduce energy consumption which included new regulation on energy efficiency standards for air conditioning units.

Since 1992 conservation standards from the Energy Department for manufacturers of residential central air conditioners and heat pumps have been issued. New a/c units are much more efficient than they were in 1990 utilizing 50% less energy to operate.

What will happen with the future of air conditioning? As we all know new technologies are always on the horizon in many different industries including HVAC so we will see what comes down the pipeline in the future.

When is it Time to Upgrade your Current Air Conditioner? Use These Tips to Help you Decide!

new and old air conditioners

Upgrade now and avoid headaches later

Although it is still very cold in most if the northern states, Southwest Florida (SWFL) has the perfect weather.

Season 2015 is in full swing in SWFL and our seasonal residents are enjoying the warmer climate and beautiful beaches.

In a few months season will be winding down as it grows warmer in northern states and SWFL’s seasonal residents will be heading north leaving their Florida homes for the summer.

Summer months in SWFL include sweltering heat and high humidity,  Although people will be leaving, their home will remain here in these hotter temperatures. This is where your air conditioner is very important because everyone leaves their a/c unit running all summer long to help combat problems from arising including mold and mildew.

It can be difficult if your air conditioner breaks down during the hot summer months and you are in another state because you will have to make decisions on repairing or replacing your unit while out of town.

A great way to help avoid this problem is by having your a/c unit serviced just before you leave or replacing your a/c unit before leaving for the summer. So, how do you know when it is time to replace your a/c unit and not just try to repair it?

Use these tips to know when it is time to replace your current a/c unit:

  • If you notice your a/c unit is not cooling as it should or if some rooms in your home are warmer than others.
  • Do you notice your air conditioner is making strange noises and these noises continue even after being repaired.
  • Your a/c unit keeps breaking down and requires frequent repairs.
  • If you have an older a/c unit it can have problems then stop working completely plus older units are less efficient.

Upgrading to a new higher efficiency unit before leaving town will help ensure that your home will stay cool all summer while you are away and when you return next season, your new a/c unit will keep you cool all season long plus you can enjoy it for years to come.

With over 25 years of experience, RDS Air Conditioning has a great reputation providing a/c services for many SWFL home owners and business owners.

If you need a/c repair, a/c maintenance or a new a/c unit installed, RDS Air Conditioning will provide excellent work at a reasonable price and fantastic customer service.

10 Important Questions to Ask Yourself About Your Air Conditioning Unit

23 Jan
get rid of that old energy burning a/c unit

Only have a new air conditioner installed when you really need one but it is important to buy a new a/c unit at the right time as to not waste money on an old outdated model.

The 2015 SWFL winter season is in full swing. This year, winter runs from December 21 to March 19th.

While people who are staying north for the winter will be experiencing bitter cold and snow, SWFL will enjoy many warm sunny days.

Whether you live in Southwest Florida year round or are a seasonal resident, many of you will have your a/c unit running throughout the year.

The more your air conditioning unit runs, the higher your electric bill.

So, how can you efficiently keep your home cool all year long and still save money on your electric bill?

Start by taking a look at your current a/c unit and ask yourself these questions:

  1. How old is your a/c unit?
  2. Does your a/c unit get regular maintenance?
  3. How often do you change the filter/s in your a/c unit?
  4. Has your air conditioning unit had a major component failure?
  5. Does your a/c unit require frequent repairs?
  6. Does your a/c unit have to work harder to keep your home cool?
  7. Are your electric bills high?
  8. Does your a/c unit have frequent break downs?
  9. Is your a/c unit doing a good job of cooling your entire home?
  10. Are some rooms in your home cooler than others?

If your a/c unit is old and needs frequent repairs, has break downs, is not cooling your home consistently and you have high electric bills, it is probably time to have a newer more efficient unit installed.

Even if your current older a/c unit receives regular maintenance and you change the filters on time, it is using much more electricity than a newer more efficient model.

Replacing your current air conditioner is a big decision but according to FPL, when you upgrade your current outdated air conditioning unit to a new high efficiency model, you can save about $400.00 a year on your electric bill. That is considerable savings!

After you make the decision to purchase a new air conditioning unit there are some other things to consider:

  • What size a/c unit will you need?
  • What is the efficiency rating of the unit you will purchase?
  • What FPL rebates are available?

It is important to hire a Certified Licensed Florida contractor to install your new a/c unit to make sure the work is done correctly. They will also be able to answer all of your questions regarding the correct size unit you will need for your home or business, the efficiency rating and any rebates that are available through FPL.

RDS Air Conditioning specializes in everything to do with a/c units including installation, repair and maintenance. They have a geat reputation in SWFL with many home owners and business owners for providing excellent customer service at a fair price.

Life Before Air Conditioning

sweating without a/c

A tuned a/c unit runs more efficiently!

When it’s hot outside many of us just walk into our homes or a business and almost instantly the cool air starts cooling us down. We don’t even think about it, right?

Well, think about what it would be like without air conditioning.   Here are some cool facts about life without air conditioning.

Before air conditioning:

  • Many industrial workers had the entire month of August off because it would be too hot to work inside.
  • The government would shut down during summer months and re-open when it became cooler outside. Many people blame the invention of the air conditioner on government bureaucracy because with the ability to cool the room, they could stay in session through summer months and have longer sessions.
  • Archetcture and design of buildings have changed.  Brick, breezeways and sleeping porches were designed into homes and buildings to help keep people cool. Many modern structures would be unbearable without air conditioning in the summer.
  • When hospitals became air conditioned, the cool air helped patients with diseases and new born babies live longer by decreasing bacteria and advancing surgical technologies.
  • There was no effect of a/c on education.  Although school would let out for the summer due to the sweltering heat, when air conditioning came along, schools were still out of session during summer months.

So, next time you walk out of the heat into a nicely air conditioned area, remember how far we have advanced over the years with daily comforts.

Another good thing to remember is that your air conditioner should be checked out twice a year so that you can continue to enjoy the cool, all summer long without interruption.

A cleaned and tuned a/c unit runs more efficiently and uses less electricity. Call RDS Air Conditioning today and we will gladly come to your home or business to tune up and clean your a/c unit.
