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.

How Long Should My Air Conditioning System Last Before Needing to Be Replaced?

25 Feb

To make your ac system last as long as possible, follow these guidelines…

SWFL is a unique area with a subtropical climate and many of our residents are here seasonally.

When it comes to an air conditioning system, many individuals who live up north have the same expectations for their ac systems here in Southwest Florida.

We are often asked, “how long should my air conditioning system last”?

That is a question that can’t be answered simply because there are many variables that come into play:

  • How old is the ac unit?
  • How often is maintenance performed?
  • How often do you change the filter?
  • Do you keep debris away from the outside unit?
  • How often does it run?
  • As soon as you hear a noise or problem, do you get it fixed or let it go until a breakdown happens?
  • Is your ac unit the correct size for the space (not oversized or undersized)?

In SWFL, the average ac unit is running about 3000 hours a year and that will rack up many miles quickly. There are some really good thermostats on the market that feature apps that you can download to your phone to control the temperature from any location.

For example, if you are away from home, you can increase the temperature and when you know you are going to return, open the app on your phone and decrease the temperature to make your home cooler by the time you arrive.

This will save on electricity and the amount of time your ac unit is running. To answer the question how long should your ac unit last before it needs to be replaced? On average is between 8 to 14 years.

In SWFL, ac systems don’t last as long as they do up north due to our sub tropical environment plus chemicals from salt-water, sulphur and farming (many communities are built on old farmland).

To get the most life out of your ac system and to try to make it last as long as possible before having to be replaced:

  • Change the filter on a regular basis – Tip: when you change the filter write the date on the side of the filter facing out so you can easily keep track of the last time it was changed.
  • Regular maintenance – Tip: It is a good idea to sign up for a maintenance agreement so that your ac system will be serviced twice a year.
  • The size of your unit – Tip: Have an HVAC contractor install your ac unit since they can help you decide on the best unit to fit your needs and space.
  • Have problems fixed in a timely manner – Tip: As soon as you hear a noise or detect an issue, call an HVAC contractor to fix it. Letting a problem go on can cause more damage over time.

The life of your ac unit depends mostly on you and how you care for your ac unit once it is installed by having regular maintenance done and having problems that arise fixed right away.

Common HVAC FAQ’s

8 Feb

Contact RDS Air Conditioning if you have a question that is not answered here.

Q: Why is it recommended that I change my a/c filter on a regular basis?
Changing your filter regularly helps to improve indoor air quality plus keeps your air conditioning system running with proper air flow while reducing airborne allergens and dust.

Q: What can I do to help between regularly scheduled a/c maintenance visits?
Use extra care when trimming weeds near your a/c unit to avoid wire damage. Keep the area around your a/c unit clear of weeds, clutter, and debris as they can interfere with airflow to the unit. Do not let pets urinate on your a/c unit because pet urine causes damage.

Q: Why is my a/c system is freezing up?
It could be a dirty evaporator coil which over time may cause reduced air flow, inadequate cooling and freezing up of the unit. Low refrigerant due to a leak/s in the lines, valves, joints or loose fittings from vibration or friction. Defective blower motor running at the wrong speed or starting and stopping or relay that only intermittently starts can cause freezing of your a/c unit.

Q: What does HVAC stand for?
Heating, Ventilation and Air Conditioning.

Q: Why should I replace my current air conditioning system?
If your current a/c system is old, in need of an expensive repair, causes increased energy bills, or isn’t cooling efficiently, it may be time to consider replacing your older unit. Newer a/c units are up to 60% more efficient.

Q: Do I need to be concerned with indoor air quality?
According to the EPA (Environmental Protection Agency), air pollutants can be up to 100X higher indoors than outdoors. That is why it is important to use the appropriate a/c filter to fit your needs and change it regularly. Also, you may want to consider an air purification system for your home or business.

Q: How long will my new a/c system last?
The average lifespan for a new a/c system in Florida is 10 to 15 years. Your a/c unit will last the longest with regular maintenance and suggested repairs.

Q: How can I find the system that is right for me?
RDS Air Conditioning will help you choose the most efficient unit that fits your specific needs ie. size and age of your home, number of rooms etc for the best possible price.

Are you stressed out? Are your home appliances contributing to your stress?

Let RDS Air Conditioning help reduce your stress

According to the National Institute of Mental Health, stress can be defined as the brain’s response to any demand or change.
Changes can be positive or negative, as well as real or perceived and can be mild or major.

Also, not all stress is negative.

For example, winning the lottery is stressful and that can be a positive stress because then you can pay off bills and perhaps if you make good choices with your new wealth, have an easier life.

The National Institute of Mental Health says that there are at least 3 types of stress and they all have physical and mental health risks associated with them.

1. Routine stress – The day to day stressors including family and work.

2. Negative change stress – Stress from acquiring an illness or getting divorced.

3. Traumatic stress – Where one is in danger of being seriously injured or killed such as in war, a major accident, natural disaster or assault.

Stress has negative affects on the body and systems. Although stress affects people differently there are common ways humans experience

  • Digestive symptoms
  • Headaches
  • Sleeping difficulties
  • Irritability
  • Feeling depressed
  • Feelings of anger

People who are under chronic stress have more colds and virus’ plus the flu vaccine is even less effective.  If you are stressed out or have chronic stress here are some tips to help:

  • Have a good support system – Be in touch with friends and family or other people in your life you can talk to who usually help you to feel better.
  • If you feel like things are too much seek out a qualified mental health professional.
  • Make time for relaxing and enjoyable activities.
  • Try to eliminate stressors in your life.
  • If you or someone close to you is in crisis, call the toll-free, 24-hour National Suicide Prevention Lifeline at 1-800-273-TALK (1-800-273-8255).

A survey was done with over 1000 homeowners in the USA to find out the average stressors a homeowner experiences and what they worry about most in their home.

34% said that the biggest potential stress for them is the breakdown of a major home appliance and that it would need to be repaired. In 2014, 68% of these homeowners reported that they had to repair or replace a major appliance or home system.

52% tried to make the repair themselves which caused even more damage or they wasted money and an air conditioning problem accounted for 21% of these.

It is hard for people to quickly make big changes even to eliminate or cut down on stress so if you start with smaller changes and keep removing stressors from your life
or learn better coping strategies, your stress level will probably diminish.

Having a good a/c person you can rely on if anything goes awry with your a/c unit can at least help eliminate this stress. RDS Air Conditioning is standing by ready to help solve your a/c issue.

If your air conditioner needs maintenance or repair or if you need a new a/c unit, contact RDS Air Conditioning a Certified Florida Contractor – Lic.# CAC1816713.

Is Your A/C System Putting Your Home at Risk for Fire and Water Damage?

15 Dec

water damage from a/c unit

Maintaining your air conditioning system is important because it constantly runs and coupled with the hot weather in Southwest Florida, there are many things that can go wrong.

Regular maintenance can often catch problems early or prevent them from happening.

One common problem that can occur from negleting having your a/c unit regularly serviced is water damage to your home.

Water damage can occur when the drain line to your a/c system becomes clogged.

The accumulation of dirt, debris, algae and even mold in the drain line causes it to become clogged.

How does dirt enter the drain line?

  • If your air conditioner is running without a filter or you wait longer than you should to change the filter
  •  A lot of construction being done in our area causes extra dirt and debris to float in the air
  • Dirt and debris that normally floats around in the air

What can happen if my drain line gets clogged?

  • Thousands of dollars in water damage to your home – The water backs up in your a/c unit’s drain pan because the water must have someplace to go.
  • Fire – A fire can start in your home due to leaking water backing up and reaching electrical parts in your a/c unit.
  • Harmful contamanents grow in your a/c drain line – Mold, mildew, virus’ and bacteria.

What are signs that my drain line is clogged?

  • Noticing stains on your ceiling
  • Your a/c unit stops working
  • Your home feels more humid than normal
  • You notice water actually leaking from your ceiling

Preventing your air conditioner’s drain line from clogging is easy. Change your a/c unit’s filter on time (every month or two). If you have pets or a lot of dust in your home, you may need to change it more often.

Scheduling regular maintenance from a professional a/c contractor will help keep the line clear and your a/c unit running at max potential.

A float switch can be installed to shut off your cooling system if it detects that water is backing up before it gets too far.

Is Your A/c Unit Protected Against Power Surges?

21 Sep
a/c surge protector

You protect your computer, television and many other electrical appliances in your home but are you leaving something out?

Many people do not think twice about adding a power strip surge protector to their home to protect computers, televisions or many other electronic devices.

Most of these items cost well under $3,000 but an expensive item in your home that is not often protected against power surges is your air conditioning unit.

Basically, a power surge is a spike in the electrical current in your home. Although it is very brief (1/1000 of a second), it can still cause damage to anything in your home that runs on electricity.

Most power surges are caused by lightning but they can also be attributed to faulty wiring or appliances (dishwasher or refridgerator).

Appliances use a lot of energy to start up and shut down which can interrupt your home’s steady electrical flow.

Power surges can degrade the wiring and components in your a/c unit, cause a/c interruptions plus damage and reduce the life of your air conditioning system.

An easy thing that you can do to protect your air conditioner from power surges is to have a surge protector installed on your a/c unit.

A surge protector works by shunting the voltage to ground. A good ground is imperative. Also, it must be installed properly. It is important to have an HVAC contractor install your a/c unit’s surge protector to make sure it is installed properly for correct operation.

Florida has about 1.4 million lightening strikes per year so there are many opportunities for power surges.

Contact RDS Air Conditioning to have a surge protector professionally installed on your a/c unit to protect it against power surges. RDS Air Conditioning is a Certified Florida Contractor. Lic. #CAC1816713.

Is the Air in your Workplace Making you Sick?

5 Sep

commercial air purifierAccording to the Asthma and Allergy Foundation of America, “A variety of vague and hard-to-pinpoint symptoms are experienced by an undetermined, but possibly sizable number of adults and children. Occasionally, they may suggest allergy or asthma, but most often the symptoms are much wider in scope.”

If you own a business, you should consider the people who visit your business including yourself, employees, customers, service techs, other business people, friends and family. How many of them may be affected by the environment in your building?

People with asthma, allergies and/or sensitivities can experience congestion, itchy eyes, runny nose, difficulty breathing or other aggravating symptoms.

There are all types of odors, air pollutants, VOCs (volatile organic compounds), smoke, mold, bacteria and viruses that you probably may not even know exist in your business environment. Walls, furniture, mold and carpets are just some of the things that can be emitting these into your environment.

Employees who have allergies or are sensitive to something in their work environment may miss more days of work or be less productive because they do not feel well and/or are dealing with irritating symptoms.

There are things you can do to help keep your employees, customers and anyone with allergies or sensitivities more comfortable while spending time at your place of business.

1. Use non VOC paint on walls or anyplace where paint is used.
2. Place Eco Friendly furniture in your workplace for employees to use and in your customer waiting area.
3. Install chemical free carpeting or green flooring like cork, natural linoleum or non glued laminate.
4. Have your a/c unit maintained and duct work cleaned.
5. Have an Air Knight REME air purification system installed in your place of business.

The Air Knight REME is designed to help eliminate sick building syndrome by reducing odors, air pollutants, VOCs (chemical odors), smoke, mold bacteria and viruses. The Air Knight REME is easily mounted into air conditioning and heating system air ducts where many sick building problems start.

Living with asthma, allergies or sensitivities is no fun and can be very irritating and debilitating. As an employer, it is important that your employees and visitors to your business feel comfortable and want to return often.

RDS Air Conditioning installs the Air Knight REME for commercial buildings and The Air Knight Residential Air Purification System to purify the air in your home.

14 Tips for Saving Money on Your Electric Bill

10 Jan
save money on your electric bill

With a few tweaks you can reduce your electric bill.

We all use electricity everyday for lighting, cooling and heating our homes and water plus for running appliances and technology.

Every month when your electric bill arrives and you see the total, do you ever wish you knew ways to reduce that number?

Here are some tips for saving money on your monthly electric bill:

  1. Have a programmable thermostat installed in your home and save up to 10% on your electric bill.
  2. Install solar energy screens (mesh like screens) into your windows to block heat from the sun getting into and heating your home.
  3. Use energy saving appliances.
  4. If you have a refrigerator in your garage and your garage is not air conditioned, it can add to your electric bill.
    Refrigerators are made to be in an air conditioned space and when it is not, the refrigerator’s compressor will have to work much harder to keep it cold.
  5. The sun shining on your roof and home can cause heat to accumulate inside. Plant trees with shading leaves around your home to block the sun but be careful not to plant anything close to or over top of your a/c unit so that the air around your a/c unit can flow freely.
  6. Reduce your water heater temperature from 140 degrees to 120 degrees.
  7. Turn off your room’s ceiling fan when you leave the room. 
  8. According to FPL, plug your electronics into a power strip to save on phantom loads. Turn the strip off when not in use and save up to $100 a year.
  9. Choose energy saving bulbs.
  10. Have an a/c professional tune up your air conditioning unit to keep it running efficiently to save on your electric bill.
  11. Don’t use more water than needed when doing laundry. Set the water level to match the load size.
  12. Dry clothing faster by cleaning the lint filter between every load and have your dryer vent cleaned regularly. 
  13. Make sure your a/c duct work is not leaking as this can drive up your electric bill.
  14. Do not run your thermostat temperature lower than needed and raise it when you go out.

As you can see there are ways to streamline your monthly electric bill. RDS Air Conditioning can help by checking to make sure duct work is not leaking, keeping your a/c unit tuned up and maintained to run as efficiently as possible,  installing a programmable thermostat into your home and by cleaning your dryer vent.

We repair, maintain a/c units and perform new air conditioning installations: Serving Naples, Bonita Springs, Estero and Fort Myers. Don’t settle for less use RDS!

Life Before Air Conditioning

15 May
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.

History of the Air Conditioner

22 Apr
Willis Haviland Carrier

Air conditioners have become more efficient over time

Did you know that the air conditioner has been around since 1902? It was invented by Willis Haviland Carrier who was an electrical engineer.

There was a paper company (Sackett Wilhelms Lithographing and Publishing Company) in New York and during the summer they had a humidity issue where their paper stock would absorb moisture and there was difficulty with the ink application on the paper.

Carrier came up with the idea to have the air in the building pass over chilled pipes which decreased the humidity in the building and fixed the moisture problem in the paper. An added benefit with this system is that beside eliminating the moisture problem with the paper, it also lowered the air temperature in the building.

Carrier saw the huge potential in this new technology and it wasn’t very long before air cooling technology spread to stores and theaters where patrons could shop or watch a show in cool comfort during summer months.

The air conditioner was first called an “Apparatus for Treating Air”.  It wasn’t until 1906 that Steware W Cramer (who owned a textile mill in North Carolina) coined the term “air conditioning”. The technology behind the air conditioner has not changed very much over the years except major strides have been made with making air conditioning run more efficiently.

With regular maintenance your air conditioner can run efficiently and at peak performance.  It is important to have your a/c unit maintained to catch small problems that may arise and fix them before they turn into a larger problem.  RDS Air Conditioning has a very affordable maintenance package to keep your air conditioner running at peak performance all year long.

Summer is just around the corner so call RDS Air Conditioning today and let us check out your a/c unit so that you can stay cool and comfortable without interruption.
