The Science Behind How Air Conditioners Work

Air conditioners are probably one of the greatest inventions on earth. They make our surroundings cooler, and our work and home environments more comfortable. It is certainly worth knowing how air conditioners work.

Air conditioners utilize chemicals called refrigerants which quickly convert gas to liquid at low temperatures. These compounds continuously evaporate and condense within the coils of the unit. The refrigerants, along with the fans, ducts, and vents in the system, move and transfer air from the inside to the outside.

Basically, a conventional air conditioner is equipped with these main parts: a compressor, a condenser and an evaporator. The set-up and processes involved are essentially the same and may differ slightly because of the different air conditioning variations. The first step involves the chemical compounds which reaches the compressor as a low-pressure, cool gas. As its name suggests, the compressor, which is a large electric pump, compresses the gas. This exerts pressure on the gas and as a consequence, the molecules are packed closer together, resulting in high energy and temperature.

This high pressure, hot gas then makes its way into the condenser which facilitates the transfer of heat and changes the gas to cool liquid. The liquid flows into the evaporator. The evaporator acts as the receptacle or container of the liquid refrigerant and transforms the liquid into gas. It is at this stage when heat is extracted from the surrounding air and cool gas is produced.

Air conditioners have fans that circulate and blow air from the inside to the outside. Cold air is denser than hot air; thus, hot air rises and cold air sinks. To address this, the machines also have vents to draw the air down into ducts, continuously removing the hot air and keeping the air cool. The entire process is repeated all over again until such time the room is at the preferred temperature.

This modern day machinery is indeed a result of the brilliant exploitation of the wonders of science — a combination of physical law and chemistry. For air conditioning and heating needs, do not hesitate to give us a call.

Temperature Control Tips & Tricks For HVAC Systems

Just like any other machine or device, HVAC systems wear and tear over time. Therefore, it is up to the owner to schedule regular professional checkups and use good practices when operating the HVAC system. A well maintained air conditioning system lasts for long and operates efficiently. So, to get the best out of a HVAC system, one has to know some of the HVAC tips and tricks.

Maintaining Filters

The air filters have to be cleaned every month so as to enable smooth flow of air in and out of the HVAC system. If the filters cannot be cleaned, the owner should replace them with new ones. There are many types of filters available in the market. However, the recommended ones are electrostatic filters. Cleaning the filters might not be a straightforward thing to a rookie. So, it is advisable to check the user manual for instructions.

Cleaning Condenser Unit

The smooth-running of the condenser unit plays a huge role in ensuring efficient operation of the HVAC system. Therefore, the owner should remove leaves and debris that has settled on the outdoor condenser unit. The condenser fans must also be kept running efficiently. This is done by cleaning the fan blades and coils before the cold seasons.

Clearing Vegetation

All vegetation that is close to outdoor HVAC units should be cleared. There should be a clearance of about 2 feet between the vegetation and the HVAC units. This keeps the fan grill clean at most times.


Since HVAC systems have moving parts, i.e. motors, the owner should lubricate them at least once a year. This is applicable to HVAC systems that have oil ports. For those that do not have oil ports, it is advisable to let a professional do the oiling. When lubricating the HVAC system, one should use non-detergent lightweight SAE 20 oil. Also he or she should not add more than 10 drops per port.

Those are some of the few HVAC tips and tricks that can be used to optimize the operation of HVAC systems. You must know them so as properly maintain your system. Moreover feel free to call us for all of your heating and air conditioning needs if at all you need a professional.

Why A Whole Home Electrical Suppressor Is Important

A whole home electrical suppressor is a device which acts much a surge protector. It allows only the electricity needed by appliances within the home and cuts out excessive voltage from the supply. Doing this shields the household equipment from any trouble which could result from electrical surges.

Such devices are normally wired to the electric service box and located close by to protect the appliances in the home. Typically, their prices range from $200 to $500. There are several reasons why a homeowner needs to invest in such a device.

The Pressing Need for Surge Protection.

In the past few years, a lot has changed within the homes in terms of electronics. Appliances such as washers and dryers have circuit boards. There are now more of such devices along with LED lighting. All these need protection from power surges.

Presence of Other Perils.

Contrary to popular belief, most surges are caused not by lightning, but by short, intense bursts known as transients. These are normally introduced into the home’s electrical grid by the appliances. Though it’s unlikely that a large surge will take out all appliances at once, frequent occurrence of small surges will result in impaired performance of electronics.

High voltages in the utility lines can also cause harm to the home’s systems. This brings in the need for surge protection that encompasses the whole house at the service panel. Though lightning still poses a risk, there’s virtually no safeguard for a direct strike. However, lightning rods can offer some protection.

Protecting all Electronics.

Though most surges come from household devices, any gadget on a dedicated circuit sends back the surge to the main panel. Backup generators can also send power surges through electrical lines when they come on. At the breaker panel, a surge can be shunted to shield other devices within the home. A protection system for the entire house will shield the building’s wiring along with all the outlets.

The Need for Layered Surge Protection.

If a surge is sent through a shared circuit, all the outlets become susceptible. This is why surge protection needs to be layered in the building to be both at the point of use and the electrical service. For home entertainment systems, one should use power conditioners that possess the capability to suppress surges and supply filtered power.

Most homes whose service is rated at 120 volts can be sufficiently shielded using an 80kA surge protector. If subpanels are used, additional protection of half the chief unit’s KA rating should also be used. In lightning prone areas or if heavy machinery is being used nearby, then it’s best to go for an 80kA rating.

In fact, there are a multitude of reasons as to why having an air conditioner installed in the winter months is actually easier. Although at this time homeowners have their furnaces going and heat pumps functioning and maximum speed, it is only a matter of a few months before an air conditioning will be needed. If your home needs an air conditioning system, or a replacement now is the time to buy.

Why To Install In The Winter Months

In the cooler months the installation of an air conditioner is actually easier. Most often in order to install an air conditioner the attic space must be accessible. In the heat working in an attic can be dangerous as the temperature may be too hot. By installing in the winter time you can ensure that the temperature is a safe condition. This will also save time, which will reduce the cost of the system. Often, buying an A/C system in the winter is cheaper anyway because it is not in demand. If you have an older system, you should consider replacing it now. Replacing an older system now, will ensure that the first day of hot weather your system will start of beautifully. You do not want to attempt to operate your system on the first hot day only to find out that you are unable to. By purchasing in the early winter you can guarantee a better price. Manufacturers tend to increase pricing in the late winter. This allows them to capitalize on the demand for air conditions in the summer months.

There are a variety of reasons to consider purchasing an air condition system now. Having it installed in the winter is not only cheaper, but it will also save time. Replacing an old air conditioner in the winter months can ensure a cheaper system as well as lower labor costs. Your neighbors may think your nuts, but go ahead and have your air conditioning installation done now.

Facts And Prevention On Carbon Monoxide Poisoning

Carbon monoxide (CO) is a chemical compound that is a colorless gas that may come in many forms like fumes from vehicles, stoves, burnt charcoal and wood, heating systems, as well as from chemical plant companies that uses gas. Poisoning occurs when both humans and animal inhale this deadly fumes. The issue on carbon monoxide poisoning is a serious threat that might cause severe illness and death.

Carbon monoxide poisoning is life threatening because the red blood cells easily absorb carbon monoxide levels in the body. The presence of high amounts of CO in the body prevents oxygen from coming in; thus, the experience of the symptoms stated above. Vast amounts of carbon monoxide may combine with proteins in the body and would destroy the tissues.

Some of the Symptoms Related to Carbon Monoxide Poisoning
Some people are not very informed about what is carbon monoxide poisoning. A person who inhales a good amount of carbon monoxide will experience some of the symptoms like chest pain, confusion, dizziness, nausea, headache and weakness. Some of the most serious ones are left unconscious because of the lack of oxygen in the body.

Prevention of Carbon Monoxide Poisoning
All people are at risk in regards to carbon monoxide poisoning. First, identify the appliances in the home that contains carbon monoxide. This would include the car as well. Have all these appliances serviced- heaters, ovens, portable flameless chemical heaters, and electric gas regularly to prevent leakage. A battery operated CO detector may also be placed in the security of everyone in the home.

Vents are most important to prevent leaks of deadly fumes. All appliances that are operated by gas must be vented to prevent carbon monoxide build up in the home. The fireplace must be cleaned so that any blocked debris may be removed. Anything that blocks the chimney may result to CO buildup. Make sure that vent pipes should be slightly higher as the fumes are meant to be released outdoors. Any leaks found in these vents must be serviced by a technician. Finally, have a mechanic check the car’s exhaust system. Most accidents reported are due to the fact that people don’t understand what is carbon monoxide poisoning in relation to cars.

How Does an Air Conditioner Work?

It is always fascinating to know how things around us work. Air conditioner is one the most used machine around the world, especially in hot climate, for bringing room temperature down to comfortable margins. However, very little is known to the user about how it works. If you want to know ‘how does air conditioning work?’, then this article is for you.

Air conditioning system works much the same as refrigeration system. The basic concept in both the systems is the same except that refrigeration generally brings the temperature drastically down in a small and closed space while air conditioning generally brings temperature down to comfortable levels in larger spaces. However, the most common principle in both the systems is the use of compressor and condenser. Also, a chemical is used in both the processes. This chemical converts to gas and liquid form quickly thus helping in bringing the temperature down.z

To understand the basic function of this chemical, you can consider it like an agent which propels the heat from the inside of a room to the outside environment. This is done in cycles over and over again. The main components of an air conditioning system include a compressor, a condenser and an evaporator.

The chemical, which begins as a fluid, enter the compressor. At this stage it is a cool low pressure gas. The compressor applies pressure on the fluid. This leads the liquid turn to gas owing to the higher energy state it has been brought to.

Its temperature is also raised in the process. This hot gas is routed into the condenser. The condenser works more or less like the radiator of a car and helps to dispose of the heat into the environment. The gas, which is now once again converted to liquid, exits the condenser. Its temperature is lower now as it has dissipated heat. This liquid now enters the evaporator through a narrow opening. Once again, the liquid changes to gas and extracts heat from the room air. When it gets heated, it again turns to gas and the complete cycle is repeated. There’s a suction pump in the air conditioner which sucks the hot air of the room. After the complete process, cold air is released into the room once again. How air conditioners work is just one of the amazing principles of science, there’s more if you want to know.

Prepare For Winter With A Little A/C Maintenance

An important part of home maintenance is taking care of your HVAC system. A little end of summer air conditioning maintenance is the best way to be sure it will be ready to cool your home when spring rolls back around. Of course, prolonging the lifespan of your equipment is important, especially given the high cost of a replacement HVAC system, so take a few minutes at the end of the season to take care of essential A/C maintenance.

Most people know that they need to replace their air filter on a regular basis. Whether you have a washable filter that can be reused or you have a disposable filter, it is important to make sure your HVAC system has a clean filter. Typically, the filter will need to be changed once a month; however, if you are shutting down the A/C until next summer, replacing the filter now will ensure your cooling system will be ready to start cooling your home when the temperatures begin to climb again.

When your air conditioner is running, air is drawn over the evaporator coils, removing the warm air and replacing it with cool, comfortable air; however, the coils and fins in your indoor unit can get dirty. Dust and other airborne debris can leave them dirty, blocking air flow and diminishing the cooling capacity and efficiency of your air conditioner. For good airflow and proper ventilation the coils and fins should be wiped clean at the end of the season.

Similarly, your outdoor condenser unit will collect dirt, pollen and other debris that can make the unit run poorly. Gently spray with a garden hose and remove anything from around the unit that is blocking the airflow.

Finally the drain line and condensate pan should be emptied. The line needs to be free of any type of blockage and there should be no water sitting in the condensate pan. Completing these end of season A/C maintenance procedures will leave your air conditioner ready for another summer of efficient cooling.

Proposed Changes For Higher HVAC Efficiency Standards

Many people are unaware of the proposed changes the Department of Energy tried to implement back in 2013. While they began working on new higher minimum requirements for HVAC efficiency in 2009, the changes were to be made effective in 2013. Unfortunately, this plan to decrease energy consumption ran into a few obstacles which resulted in a court delay for implementation of the new HVAC efficiency standards.

Basically, in order to reach the proposed AFUE or annual fuel utilization efficiency of 90 that the DOE was striving for, homeowners would need to install a condensing furnace in their home. The higher fuel efficiency of the condensing furnace would be the only combustible heating equipment capable of achieving the required level of HVAC efficiency.

The problem with the new requirements is that it would put many families in a very difficult financial position. While there would be the benefits of increased energy efficiency, retrofitting homes to meet these requirements would ultimately be very complicated and costly. A condensing furnace would require extensive retrofitting in an effort to make use of the two separate heat exchangers.

Most homes are equipped to handle the installation of a traditional heating system; however, with the condensing furnace, a second heat exchanger is necessary to capture and condense the hot water vapor which is created during the use of a combustible heating system. Rather than exhaust this wasted energy out of the home, the condensing furnace is able to capture it and use it to provide a more efficient way to heat the home.

There is certainly no doubt that a condensing furnace can meet the higher AFUE standards for increased HVAC efficiency, but it can also require a financial burden for the homeowner who must pay for extensive retrofitting and installation costs. Due to these problems, the HVAC industry was able to successfully argue against implementation of these higher standards, at this time. With a delay in implementation, homeowners still have an opportunity to increase the efficiency of their HVAC system.

Save Money When You Diagnose HVAC Problems With Simple DIY Solutions

Do you have an A/C not working? Think twice before making a call for professional repairs. There are many AC problems that you can fix on your own and that will allow you to save the cost of an expensive AC service call. Troubleshooting air conditioning problems can be as simple as going through the following tips.

The first step necessary in order to diagnose HVAC problems is to determine whether or not you have electrical service to your home. If your home is without power, your air conditioner will also not have the electricity needed in order to operate. Once you have determined that you have electricity to your home, it is necessary to check to see if the AC system is getting electricity. Check the fuse or circuit breaker for your cooling system to be sure the circuit hasn’t been tripped.

If you have electrical power to your air conditioner, other factors are causing the problem. Check the air filter, if you find that it is dirty, chances are your air conditioner is not providing sufficient cooling. This can also lead your system to freeze, leaving you with little or no cool air. You should also make sure that your thermostat has batteries in it and that it is set properly to cool your home.

Many air conditioners have a built-in switch designed to protect your home from water damage. This switch will turn off your air conditioning system if the drain line is clogged. Check the drain line and flush it out if necessary, then empty the pan of water. Additionally, sometimes this switch can inadvertently get switched off if the unit or pan is accidentally bumped. If there is no water in the pan, check to be sure that the switch is still on.

When troubleshooting air conditioning problems be sure to check both the indoor and outdoor units. There are switches both by the inside air handler as well as by the outside unit that can turn off your air conditioner. Make sure that both of these switches are on.

If you are unable to diagnose the air conditioning problem, a local HVAC contractor will be able to help. Call a reputable AC technician to get your air conditioner repaired and back to cooling your home.
