15 Fun Facts About Air Conditioning You Never Knew

When you think of an air conditioner, or heating and cooling in general, “fun” probably isn’t the first word that comes to your mind! And that’s ok, we get it; we know that just because at A-1 Heating & Air, Inc. we are passionate about all things HVAC doesn’t mean everyone is!

However, there are quite a few interesting facts about air conditioning that may pique your interest, so we’ve decided to have a little fun and share some of our favorite ones below:

Air Conditioning Fun Facts

1. Before modern air conditioners were invented, people used to cool their businesses and homes with one-ton blocks of ice. Once A/C came about and manufacturers began marketing their products, they wanted to describe things so that customers would understand. So, they referred to “ice power” and called their systems “one-ton ACs.” A one-ton AC unit produced as much cooling as melting a ton of ice, which today is the equivalent of about 12,000 BTUs.

2. The New York Stock Exchange was the first famous building to use air conditioning in 1903.

3. The world’s first commercial cooling systems were created by Ting Huan in 180 AD. His systems used fans equipped with seven wheels, each of which was ten feet in diameter! These cooling systems were cranked by just one person.

4. Willis Carrier invented the first air conditioner in 1902. He was just 26 years old when he got the idea while he was on a train platform looking at fog. In 1915, he founded the Carrier Engineering Corporation.

5. In 1930, the first air conditioning system was installed by Carrier in the West Wing of the White House.

6. Each year, the average household in America uses 40.4 million BTUs for heating, but just 9.3 million for cooling.

7. In the Holy Mosque of Makkah, Saudi Arabia, you’ll find the world’s largest HVAC system. How big is it? The system has a refrigeration capacity of 135,000 tons! As a comparison, the average residential air conditioners have capacities that range from 1.5 to 5 tons.

8. Before 1940, less than one-third of new homes in the United States came equipped with air conditioning. Today, 95% of new homes do.

9. The average American family spends over $2,000 each year on energy costs. $2% of that is on heating, and just 6% of it is for cooling.

10. Homes with low humidity feel cooler than those with high humidity levels because the dry air causes the skin’s moisture to evaporate, which cools people down.

11. It’s predicted that by 2050, 5.6 billion buildings across the globe will have air conditioning. To make that happen, consumers would need to buy the equivalent of 600 air conditioners every minute for the next 30 years.

12. Back in 1939, the first air conditioning systems were installed in a car by a manufacturer and were called weather conditioners.

13. “Summer blockbusters” became popular thanks to air conditioning because people would go to cinemas to enjoy the A/C. Movie producers capitalized on this fact and began releasing their big hits during the summer months.

14. The first residential air conditioning system was installed in the Charles Gates mansion in Minneapolis. The home was 38,000 square feet and was built in 1913. Sadly, it was demolished just 20 years later when the owner died and no one could afford to buy an enormous home with air conditioning.

15. The quality of the installation job has a direct impact on the efficiency of an air conditioner. Research shows that building owners in New York City lose up to $180 million annually in energy costs due to low-quality installation.

 

It’s important to trust the Bay Area leaders in all things HVAC for your air conditioning needs. Whether you need installation, repairs, or routine maintenance, it just has to be done right. Schedule an appointment with A-1 Guaranteed Heating & Air, Inc. today!

Top 5 Ways to Tell that It’s Time to Replace Your Home’s Windows

Windows are one of those things that many people just don’t think too much about on a day-to-day basis. They might get cleaned or decorated every so often but other than that, they often blend into the background of a house.

However, windows play an extremely important part in the structure, function, and aesthetics of your home. They can even save (or cost) you a good amount of money when it comes to heating and cooling. Windows don’t last forever, and if you’ve got ones in your home that have been there for quite a while, you may want to consider getting them replaced.

How to Tell if You Need New Windows

Following are five signs that you may need to replace your windows:

1.   Your Windows are Damaged

This may be one of the most obvious signs, whether the issue you have was caused by an out-of-control softball or you’ve spotted water damage on your windows. If you notice cracks, chips, condensation, mold, water damage, or drafts near the windows, it’s a good indication that they need updating. Condensation in between the panes of double-pane windows usually indicates that the seal is broken, and the presence of mold can indicate the same.

2.   You can Hear a Lot of Outdoor Noise

When outside noises are loud and clearer than you want them to be, you might want to consider upgrading your windows. Replacing them can improve sound performance indoors and reduce noise transmission from outdoors, as well. For better noise control, opt for windows with more panes and thicker glass to dampen sounds at various frequencies. New windows will also be properly insulated, which will improve noise resistance as well.

3.   You Notice Fading Interior Surfaces

While it’s true that fade damage is a natural byproduct of the sun filtering through windows, today’s energy-efficient windows can drastically reduce that damage. If you’ve noticed that your furniture and your wood floors are fading where the sun shines in through the windows, it’s a sign that you should consider replacing them. New windows with low-emissivity (low-E) glass coatings are available that add thermal protection by blocking harmful UV rays from shining through.

4.   Your Windows are Hard to Operate Safely

A window that isn’t functioning like it should is not only frustrating but also dangerous. There have been many instances during which a person lifted a window to open it, only to have it come crashing down on their fingers! Your windows should be easy, quick, and safe to operate. New windows today offer the ability to slide open and closed without cranking or heavy lifting (or propping them open), and they are extremely durable, too.

5.   They Have an Outdated Style

You might think at first that this reason is a purely cosmetic one; however, windows go a long way when it comes to influencing the value of your home. Windows can impact the overall curb appeal of a house quite a bit, so take some time to really look and consider whether your windows are improving your home’s curb appeal or detracting from it. If you’re planning on selling your home within the next handful of years and your windows are old and outdated, you’ll want to replace them to get the maximum price for your home.

Is It a Good Time to Purchase a Tankless Water Heater?

You may be at a point in your homeownership when you are questioning whether a tankless or traditional water heater would be the better investment for your home. There are many factors that have to be considered in order to make a solid, educated decision.

Some of these include the upfront cost, the cost savings over time, the amount of hot water your household uses each day, and others.

The U.S. Department of Energy states that tankless water heaters are up to 34% more energy-efficient than traditional tank water heaters. This number is based on the usage of around 41 gallons of water per day. Even if you use twice that amount of water each day, tankless water heaters are still up to 14% more efficient.

Main Differences between Traditional and Tankless Water Heaters: How They Work

Let’s start by taking a look at some of the main differences between the two types of water heaters.

Tankless Water Heaters

A tankless water heater weighs 25 pounds on average. These are often mounted up on a wall and take up only about two square feet of space. The versatility in placement that tankless water heaters offer means they can fit just about anywhere. This would be a big benefit to people who currently have a giant traditional tank water heater taking up an entire closet or a huge portion of a garage.

A tankless water heater will warm the water as it is pulled through the unit, which is very different from the way traditional tanks handle water.

 

Traditional Water Heaters

Yes, traditional water heaters are big and bulky; they require a lot of space. Water is kept inside of a storage tank at a consistent temperature, ready for use when you turn a hot water faucet on within the home. However, as hot water is removed from the tank, cold water enters it in order to refill the tank.

The resulting temperature of the water within drops because of this, which is why people often have to keep turning the shower dial until they finally run out of hot water.

 

Cost

One of the biggest differences between these two types of water heaters relates to cost. A tankless water heater will cost you more upfront; however, the long-term savings on your energy bills will offset that cost.

The exact amount of your eventual savings will depend on your usage habits, the cost of the system, installation costs, your location, and the differences between your new water heater and your old one. If your current system is inefficient and old, you should expect a faster payoff.

 

Temperature

Traditional water heaters must be set to maintain an internal water temperature of at least 120 degrees Fahrenheit in order to prevent the growth of various types of harmful bacteria in the tank.

However, since tankless water heaters have no standing warm water, bacteria is not a concern. The water temperature can be kept lower, which reduces the energy the system uses and also reduces your energy bills.

 

Water Filter Needs

Generally speaking, it’s recommended that tankless water heaters have a filtration system installed to filter water before it reaches the unit. Minerals, sediment, and debris can all damage heating elements within the unit. These filters are only a few dollars each and only require changing every 2-3 months.

 

The Bottom Line: To Buy or Not to Buy?

The benefits of having a tankless water heater can significantly outweigh the drawbacks, and more homeowners are switching to tankless systems with every passing year.

Top 5 Tips to Beat the Heat Indoors (And Save on Your Cooling Bill)

It won’t be long now before summer heat waves really hit California and with that heat will come air conditioning units working overtime. Undoubtedly, it will also mean that many people will be making emergency calls when their A/C units break down.

Whether you’re already running your air or you’re gearing up to, there are some things you can do to take the stress off of your air conditioning system and still keep cool indoors.

Stay Cool This Summer and Save Your Air Conditioner

Keeping your home nice and cool and adjusting some little things can make a huge difference not just in the temperature of your home but also in your energy bills this summer. Here are the top five:

1. Schedule a Preventative Maintenance Check-Up

This is by far the most important way to avoid unexpected A/C breakdowns in the middle of a heat wave. A-1 Guaranteed Heating & Air, Inc. will come to your home and perform a pre-summer inspection of your system to make sure that it’s ready for the summer ahead.

Regular professional check-ups and maintenance can not only ensure that your system runs properly for longer, but it can also reduce your chances of having to call for emergency service.

 

2. Use Curtains, Shades, and Awnings

You might be surprised at just how much heat can enter through windows and increase the temperature of your home. In fact, up to 30% of the heat from the great outdoors seeps into homes through the windows! Most of the heating effect is a direct cause of that sunlight heating up solid surfaces indoors.

When you stop or at least limit that sunlight from being able to hit surfaces, the decrease in the heating effect is significantly reduced. Using curtains and shades indoors and awnings outdoors to block the sun’s path to your home’s interior is critical.

 

3. Close Off Rooms That are Not in Use

This includes closing the vents as well as the doors. Draw the curtains or close the blinds, as well. Doing these things with rooms that are not being used helps prevent cool air from entering them and being “wasted” during the hottest hours of the day. It also can keep the warmer air in those rooms from infiltrating other areas of the house.

 

4. Check Your Insulation

Insulation often crosses people’s minds during the winter, but it’s just as important in the summer. The air barrier that good insulation foam around a door can create is a much-needed addition to keeping your cool air inside and the hot air outside.

It’s important for maintaining a more consistent temperature within the home, which means your hard-working air conditioning system can catch more of a break. Using weather stripping around windows can also help if you can’t afford new windows right now.

 

5. Plant Shade Outside of Your Windows

Did you know that a tree in full bloom is able to block at least 70% of solar heat from entering a house? That’s a huge amount of heat that you could be sparing your house from. Find plants and trees that can come between the sun and your windows, especially windows that get hit by the hottest afternoon sunlight.
