Heating and Air Conditioning

By Hank Jones


You wish to know more details on the concept in regards to the heating and cooling systems and how it can work for your newly purchased house? Read on and you'll discover many things about them and how you can have the greatest upsides from using them.

From their names alone, heating and cooling systems are actually central heating system in the form of heater or central heating boilers and often located on basements or garages of our homes. They're placed out-of-the-way since they are typically large, can emit a great deal of heat while it operates so individuals are better away from them. They can produce heat throughout our properties by pumping in warmed air using its system of air ducts and can also give steam or hot water through pipes coming from the convectors or radiators. Simply, they run with the principle of forced-air and gravity systems and they can be handled through thermostat command.

Most properties nowadays generally use electric baseboard heaters as well as in-floor gas heaters that generate radiant heat but now, more people are getting aware of the centralized heating and cooling systems and more of it will be pointed out below.

For houses, the two typical varieties of heating and cooling systems and these are the centralized ducted air systems and the radiant heating systems. Ducted air systems are the most common type and you can very easily spot it if you see properties with their air conditioning units, or furnace, and heat pump that receive hot or cool air from one source. In this system, there are also two types, the forced-air and the gravity type. With the forced-air system, you can have hot air from the furnace and you can also have cool air from the air conditioning unit. The fan from this system is the one responsible for these as it pushes the cooled or heated air from the system and into the rooms of our offices or homes.

The gravity furnace type works by carrying heated air through the system that comes from a heater which is on the ground or below the main floor. It doesn't use blowers but it uses huge air ducts and can only supply warm air unlike the other kind that is flexible.

Now, the 2nd type of heating and cooling system is the radiant heating systems. From the word radiant itself, the system uses water, hot steam or electricity to charge water and generate radiant heat and this is made possible with the use of the central boiler system that heats the water. The steam that is generated moves around through a system of tubes and pipes that are placed beneath the house's floor surface and when these pipes gets heated because of hot water and steam, radiant heat is released which warm the space.

Electric radiant system is also under this sort of radiant heat. This system works when a house is installed with electric-resistance baseboard or has a system of electric cables and sometimes foils buried beneath the floors or sometimes above ceilings. When there is the flow of electric current on these components, heat is also produced and radiated inside the room.

Auto Air Conditioning Repair: What To Do

By Berry Calverthsen


Before you can do any auto air conditioning repair, you need to understand a bit how your system works. By knowing these basics, you are able to best accomplish your auto air conditioning repair tasks. There are numerous intricate parts to an auto air conditioning repair job and many of them are unique to the auto system. What this means is that while some of the basic applications will stay the same; when examining an auto versus a central air conditioning repair, there are particular things to keep in mind.

What to Know Prior to Auto Air Conditioning Repair

The most important thing you should know is how the air conditioning system works and what would be going wrong with it. At the center of the auto air conditioning repair is the compressor. If you want to compare the system to your body, the compressor would be your heart. The Freon is the blood of the system when taking that analogy further for your auto air conditioning repair.

The compressor pumps Freon over the air conditioning system. Freon is a liquid and gas combination which is compressed and circulated through the air conditioning system. Since it is passed by pressure through different sized metal and rubber hoses, the gas will expand and contract. It makes the Freon gas extremely cold.

Once chilled in this way, the gas will make its way through metal lines to the dash of your automobile and into the evaporator core. An evaporator core looks like a small radiator, except that has cold Freon inside and not hot anti freeze. A small fan called the air conditioning blower fan sits in front of the evaporator core and blows air across this then out throughout the vents in your car.

The other part of the air conditioning device that you need to know is the condenser side. This part can remove heat from the inside of the vehicle and also works together with Freon to get this done. This part is called the Air Conditioning condenser and is placed at the front of the car. This part looks the evaporator coil and provides a similar function in that it has cold Freon going through this. However, it is designed to take heat away, not to bring cold in, a subtle difference between the two.

As you have seen, there are many important components to your auto air conditioning repair job. By understanding how all these components interact, you can better resolve your problems.

How To Choose The Best Air Conditioning

By Wanda T. Milam


Now that the weather is getting hotter, it is time to look into air conditioning products for your home or office. An air conditioner will keep your home or office at a comfortable level for living or working.

There are different types, shapes and sizes of the devices. Before buying one, always know your environment, then choose the type of equipment that will serve you best. First know, the number of people who will be served by it, the size of space and the lowest level of temperature that you will need, and your allocated funds.

The smaller the space, the less powerful the product has to be. If you only want to lower the temperature in your room, any domestic air conditioning appliance will do. They usually can be found in any appliance store and can be quite cheap whilst doing their job properly. Keep in mind that the units require external space as well, and look around your room to find a good spot for it.

Domestic units tend to be placed near windows to ease their access and avoid spacing complications. Some rooms are unable to have this done, for various windows, and require holes to be made in a wall in order to allow access to the outside. Unfortunately, some places are unable to allow these holes to be made for various reasons. Remember to have a specialist look at your room before purchasing a unit.

If you will need the entire house to be covered, you will need to think again. The devices designed for domestic use, can only handle a single room at a time. If you have more than a room, you may need to purchase several of these devices to cover all rooms. However this will eventually be costly. You can therefore consider fixing these only to the rooms that cannot do without.

Offices are sometimes harder to cool. Again, multiple window units are not energy-efficient for large offices. A central cooling unit is a better option that is more efficient but will save on electricity bills. Duct work will distribute cool air throughout the office. Cooling off a hot office will make your employees more productive and happier.

There are other kinds of air conditioning products out there, but most of them only address specific environments or needs. Keep in mind that some are more efficient than others, so it is best to look at specific details about their capabilities before purchasing one. You will see that the investment is worth it, though; after you settle on option that suits your needs, you will start wondering how you have ever lived without it.

The way that companies who do this work have gotten the process down to an art form so to speak. It may seem that they are going backwards during the installation, but that is the most effective way to do it. They start from the venting in the ceiling areas and work their way back to the cooling unit itself.

How much all of this will cost you is something you need to do before anything else. This is a major investment in your home so you want to make sure you have a ll bases covered here. As with any big job that takes time, there will be a few unexpected expenses that come up from time to time that you will want to put in your budget for this project.

The Facts About Air Conditioning

By Wanda T. Milam


Air conditioning is a system that removes heat from an environment to provide thermal comfort. It is sometimes called AC or air con. This system can refer to any form of heating, cooling, disinfection or ventilation that is done to change the condition of the air. Air con can come in the form of a machine, system or appliance. It typically uses evaporation or a refrigeration cycle to stabilize the humidity and air temperature of an environment.

The advancements in chemistry during the nineteenth century led to the emergence of air con systems we know today. Willis Haviland Carrier is responsible for the first large-scale and electrical AC system. He developed this system in 1902. It was able to control humidity and temperature, something that previous inventions had been unable to do. The first mass-produced air cons were hazardous because they used flammable or toxic gases that sometimes leaked and caused deadly accidents.

Innovation of these systems continues today. With the global warming potential comes the desire to improve air quality. Developments have become focused on energy efficiency and air-quality improvement. Some have suggested changing refrigerants used. Carbon dioxide has been proposed as an alternative.

There are two broad air conditioning applications. That is, two primary uses. These applications are comfort and process. The objective for both extends beyond temperature. They also serve to regulate humidity, air quality and movement.

Comfort applications are designed to provide comfort for a human, regardless of the weather conditions outside of the indoor environment. Within these systems, the temperature is always in range of thermal comfort. Process applications are designed to provide ideal conditions for a specific process. Human comfort levels do not determine settings. The needs of the process are used to provide a suitable setting, despite humidity, internal heat and external weather.

AC systems come in different forms. Heat pumps are a type of air con that has a refrigeration cycle capable of reversing. It is able to produce hot and cold air. Dehumidifiers are designed to remove humidity from the atmosphere. Portable AC systems have wheels that make them easy to move. Air conditioners are commonly used in transportation devices for comfort purposes.

These systems can positively or negatively impact the health of humans. Air conditioning has been known to save lives of individuals who live in areas with heat waves. It can create a hypoallergenic atmosphere in hospitals, which allows for cleanliness and safety. It can also provide relief for asthma and allergy sufferers. Some systems, commonly those in water-cooling towers, have been known to produce and spread microorganisms, which can lead to serious health issues.

Common Air Conditioning Problems

By John Kirzno


Air conditioning units may fail at any time without proper warning. Living in an area that accumulates high temperatures during the summer months may significantly result in your total discomfort. Sometimes getting a repairman can be very costly ig they have to do a lot of probing to find out the problem. Thankfully there are simple ways to easily identify common problems of your own air conditioning unit, if you want to try repairing it on your own or if you want to give the technician a heads up on the trouble.

Most air conditioning problems that might occur is its inability to adequately cool a home or an office establishment. These air conditioning problems are sometimes the result of insufficient maintenance. The easiest way to prevent problems with your unit is to have regular maintenance check-ups.

Top 4 Problems

There are four common air conditioning problems. Knowing what they are may help you to understand what a technician is referring to you when you need to discuss the options for correcting the problem. Here are the four most common problems that may cause your air conditioning system to breakdown.

The first one is faulty wiring. Having an improper, haphazard or even an uncertified wiring is dangerous. It is a potential fire hazard. Having bad wiring often prevents the system from getting enough power, or worse it can trip the circuit breaker.

Another is a low refrigerant. As we all know, a refrigerant is a chemical that cools the air. Having a low refrigerant indicates that there might be a leak or a problem with the refrigerant system. If the air conditioning system needs to be recharged with refrigerant, then it typically means that there is a leak and that it should be located and repaired.

The third problem is the malfunctioning of the outside fan. The outside fan is basically responsible for transferring the heat from your home to the outside air. If the fan malfunctions or does not run properly then heat transfer is not taking place and the unit may overheat. The worse case of all here would be that it may cause an internal damage to the compressor.

And the last among the common problems is getting a frozen coil inside an air conditioning unit. Having such only means that the filters may already be dirty or it may be caused by the low presence of a refrigerant.

In most cases, the only way to prevent such problems from occurring is to perform preventive maintenance programs. Having routine maintenance check-ups can easily detect bad wiring, low refrigerant, and airflow problems. For all these common issues, a qualified technician can quickly diagnose the problem and make necessary repairs.

Tips for Buying an Air Conditioning Unit

By John Kirzno


It can be difficult trying to decide what sort of air conditioning unit to purchase because of the fact that there are so many types to choose from. It is even more challenging when you have no real idea about what air conditioning units are and how they work. It is only when you know what they do that you will be able to decide which type is the best for you. In order to do this, you have to educate yourself about the various options that are available.

Although a central air conditioning system may be best for some households, buying them always has its trade-offs between the lower purchase cost, the long-term value and efficiency. For this reason, when only a certain area of the home requires cooling, a room conditioner is the best choice. Yet, there are several models that are suitable for cooling a designated area. That is why you must look at all the options before buying.

Types of Air Conditioners

The type of room air conditioning unit depends partially on how much you are prepared to pay and where you want it to be placed. It may seem easy if you own a house, but if you are only renting then it may require the approval of the landlord. Here are some types of air conditioning units which may help you determine the model that will best suit you.

Window-mounted air condition units are the most common economical type. It can easily install in just a matter of minutes. You can simply place it in the window and plug it to a nearby outlet. Typically it is directly mounted into an open window where they can be installed into a hole that has been cut into the wall.

The wall-mounted air conditioning units are commonly used for both domestic and commercial used. This type of unit can be mounted at the desired level from floor to ceiling. Most models are remote control operated and are energy efficient. Even though it incorporates an elegant design, the installation of this type of unit requires some renovation work.

While a window or wall air conditioner is either permanently or seasonally installed for cooling a specific room. Portable air conditioners are mobile units that exhaust hot air through a connection out a window. This type is versatile and can be relocated in minutes to another room that needs cooling. While some mobile models are multifunctional and can include dehumidifying, air purification or heating functions, which is a plus, others are just simply cooling units. Although this is considered as a convenient type, it is more expensive than window models and some can be very heavy to relocate even though they have wheels.

Another type is the split air conditioning unit which is made up of two parts. The first part is the main evaporator that is situated in the room where you want the system to work. The other part of the unit is the external condenser box which can either be placed on an outside wall or it can be installed free standing on the ground or on the flat roof.

When purchasing any of the air conditioning units, one must also consider the best features that each product has to offer. These features include convenience in using the unit, energy efficiency, easy installation, and its adjust-ability.

Upon looking into the types and the features of the different air conditioning units that are available on the market, one can now better determine which type is going to meet the requirements which will be most beneficial to your home.
