What is Freon?

what is freon

We always hear about Freon when we’re talking about HVAC, AC repairs, and maintenance. What is Freon? Simply explained, it is a refrigerant brand – but since it is the most popular and widely used refrigerant all across the world, many people just call refrigerants Freon.

Freon is a cooling agent comprising nonflammable, low toxicity gases or liquids. The cooling agent is quite commonly used in home appliances like a refrigerator and air conditioner. It is Freon that lets an AC convert hot air into cool air. The AC continues to cool the air until the thermostat drops down the targeted temperature. The temperature, however, drops through the evaporation process undergone by the Freon.

Here’s a quick video we found that shows how you can check Freon levels on your AC system so you can tell whether it is time to recharge.

The compressor in the AC compresses cold Freon gas, and a tiny bit of lubrication is added. Upon compression, the temperature of Freon gas rises. The hot Freon gas then circulates through a series of coils, which lowers its temperature, and we get cool air.

Freon, in short, is a crucial component of the AC, and it requires proper maintenance to ensure its effective working. If the AC stops cooling the room, you may want to call up a professional and get it checked. As Freon is a gas, it may leak and require refilling. But, once the leakage is diagnosed, you may have to get the AC charged with Freon in next summertime. The professional could tell you exactly about the leak and its possible cause.

The leak is diagnosed through electric equipment, a bubbling agent, or UV dye. Once the leak is diagnosed, the professional will remove the remaining cooling agent from the AC while preparing it for refilling or charging. He/she will fix the leak to ensure it doesn’t leak again. Once everything is fixed, the contractor would refill the AC with the cooling agent and test for a leak.

Getting the AC refilled with Freon gas may cost from $150 – $700 depending on the condition of the AC. Nevertheless, it costs more to refill an older unit. You can learn more about your AC Freon refilling requirement by contacting a local HVAC professional.

An air conditioner is no longer just a luxurious piece of home appliance. It is in fact a necessity that many homeowners absolutely need. Some days and nights can get very hot and uncomfortable and so it would be great if there’s an air conditioner that you can use. However, it is also important to remember that regular AC maintenance is necessary if you want to have an efficient AC that’s always functional anytime you need it. 

Maintaining an air conditioner for homes usually involves the following processes: 

  1. Cleaning of AC filters
  2. Cleaning of indoor and outdoor unit
  3. Refilling of freon when needed
  4. Complete inspection of parts to ensure efficiency

Depending on how frequently you use your air conditioners in your home, it is ideal to get it maintained quarterly or at least twice a year. For those who rarely use their air-conditioners except during the hot summer period, then once a year may also be acceptable. Eggert Cooling and Heating advises at least two times each year for a full HVAC service, and clean out on the ductwork.

AC Problems Prevention Tips

On a hot summer day, the last thing that anyone would like to deal with is a broken air conditioner. AC, just like any home electric appliance, is subject to wear and tear by time. However, time is not the only culprit. Sometimes, our rough handling can damage the AC. So, here we are with three common AC problems that often protrude from rough usage and tips to prevent such issues in the future. We also included the necessary AC problems prevention tips that hopefully would help you out. 

Reduced airflow in the room: One of the most common problems of AC is decreased airflow in the room. This generally happens when dirt accumulates in the air filter and on the coils. Basic maintenance of the AC can help prevent such a problem in the future.

Leaking refrigerant: The working of the AC largely depends on the refrigerant, which makes the hot and dry air of the room enjoyable. However, a leaking coolant may lead to reduced cooling. The leakage may reduce the level of refrigerant. As the government has set tough guidelines restricting the AC owners from re-charging a leaking coolant, you will have to call the professionals for help. The professionals will repair the leak and help you in getting the HVAC system back to the right levels once again.

Troubled electric control: Frequent shutdown and power on can damage the electric control, which means the AC will fail to maintain the apt room temperature. It is highly advisable to leave the AC on throughout the hot and humid weather. In case you have to go out for some time, raise the temperature by five degrees.

Regular maintenance by your HVAC contractor is what all you need to ensure the AC does not breaks down in the summer season. Carefully operate the AC as it may cost a lot to have one repaired and even more expensive when you need to replace your AC. Besides, a faulty AC may consume more utility and add to the expenses.

How to Save Energy With Your AC

Save Energy With Your AC

If you run your AC occasionally, there are high chances of your paying hefty price for it. Nevertheless, you can save energy without turning off the ACs. Curious to know how? Read on to learn how to save energy with your AC.

1. Set Thermostat High: For air conditioners, the lower you go, the more money you blow. So, if possible, set the thermostat to the highest temperature that will still keep you feeling cool. Maintaining a temperature that’s 10 to 15 degrees higher than the one you’re used to for 8 hours should save you up to 10% on your cooling bills every year.

2. Prevent Sun Heat: Some sun rays are good for us, just not during the hottest days of the summer when you and your family are melting in the heat, and your AC unit is doing the best it can to keep everyone cool. The heat that sunlight brings can make your AC unit work harder to cool your home, and an AC unit working hard means it’s consuming more power than it should. So, keep the blinds, curtains, and drapes closed to keep the sun out.

3. Clear Air Filter: Over time, the air filters on our air conditioners collect dust and debris, and eventually restrict airflow. When airflow is interrupted, your AC unit will strain to keep your home cool, and that will make it use more energy. Do not wait for your air filters to become clogged. Cleaning and changing them every 30 to 90 days should keep the air flowing smoothly through your unit. Also, it would be best to get help from a licensed HVAC technician whenever you need AC maintenance.

4. Use Ceiling Fan: Ceiling fans help circulate cool air throughout the house, and that means your AC doesn’t have to work as hard to pump cool air into the room. The improved air circulation should also allow you to set your thermostat four degrees higher without reducing your comfort. Ceiling fans use less electricity and they help your AC unit do its job more efficiently.

Air conditioners play a huge role in making your home comfortable. Cut on your electricity bill with the aforementioned tips and enjoy a relaxing summertime with family inside the house.

How Air Conditioners Work?

how air conditioners work

It is wondrous to see how air conditioner converts warm air into the cold air for us to relish on cool summer weather inside the homes and offices. The entire process of air conversion relies on a technique that uses refrigeration to chill the indoor air through a physical law which states that a liquid, when converted to a gas through the phase conversion process, absorbs heat.

The refrigerants are the prime compounds of the ACs that have properties to convert at comparatively low temperatures. The other components of an air conditioner include fans that transfer warm air of the room with the cold air produced by the coils filled with refrigerant.

The air conditioner converts the hot air of the room with the cold air by releasing low-pressure through coils and refrigerants that absorb the heat while converting it from a liquid to a gaseous state. It once again converts the refrigerant gas to the liquid form to ensure the effective working of the air conditioner.

For this, the compressors put the gas under high pressure which leads to the creation of extra heat that is evacuated to the outdoors. It is, in fact, this heat that we feel when passing through the compressor of an air conditioner. While the gas cools, it one more time changes to the liquid form. In short, the process of air conditioning restarts. It is an unending process unless and until the coil, refrigerant, and compressor continue to work effectively.

All these processes, of course, comes with a cost. You need to invest in a good kind of AC with the right capacity and model that would best work for a room or area of your home or place of business. These AC units do not usually come cheap. So anytime you need maintenance and repairs, make sure you’re getting in touch with a qualified HVAC technician to ensure that you can have your peace of mind and confidence that they will get the job done properly.
