Do Air Conditioning Systems Emit Greenhouse Gases?

This entry was posted in Air Conditioning and tagged on by .

Does An Air Conditioner Emit Greenhouse GasesIs it true that HVAC systems emit greenhouse gases, which are depleting our atmosphere’s ozone layer? Could your air conditioner be contributing to global warming? Yes, both are true, but there are ways you can minimize your environmental footprint.

First, you should understand the science behind HVAC units, greenhouse gases, and global warming.

How Is Your Air Conditioning System And Greenhouse Gas Connected?

All air conditioning units emit greenhouse gases because of the way they are designed to function. Take your air conditioner, for example. Your air conditioner uses electric coils and an electric pump to transfer air between the interior and exterior of your building. A condenser moves hot air to the outside while an evaporator pushes cool air to the inside. The movement of air is facilitated by a refrigerant, which functions by transforming gas to liquid and vice versa. It is this refrigerant that is a source of greenhouse gases.

When air conditioners were first manufactured, they contained a liquid refrigerant composed of chlorofluorocarbons (CFCs), which were later found to emit greenhouse gases. In 1995, U.S. manufacturers began replacing CFCs with halogenated chlorofluorocarbons (HCFCs), which have a reduced effect on the depletion of ozone. However, HCFCs still emit greenhouse gases, and the U.S. government is phasing them out of production by 2030.

How Do Greenhouse Gases Affect The Environment?

So how exactly do greenhouse gases affect the environment? Greenhouse gases deplete the ozone layer. The ozone layer is the layer in our atmosphere that protects the Earth from the sun’s UV radiation. This means that as more greenhouse gases are emitted, more of the ozone layer is depleted, and more radiation hits the Earth’s surface, increasing the Earth’s core temperature and causing global warming.

An Easy Way To Reduce Greenhouse Emissions

With this in mind, how can you protect the environment while still using your much-needed air conditioner?

One way to reduce your emission of greenhouse gases is to purchase heating and air conditioning appliances that are ENERGY STAR® qualified. ENERGY STAR is a program that was initiated by the U.S. government and Environmental Protection Agency (EPA) to establish national energy efficiency standards. Appliances that are ENERGY STAR qualified use approximately 10 percent less energy than non-qualified appliances, which means that they emit fewer greenhouse gases and also reduce your energy costs.

Next time you’re on the market for a new air conditioner or rooftop air conditioner, consider purchasing an energy-efficient model. Our HVAC service experts in Chandler at Bruce’s Air Conditioning and Heating can help you make a smart, cost-effective and environmentally conscious choice.

What Is An Energy Management System?

Energy Management SystemThe term “energy management system” refers to the process of monitoring energy usage and improving energy savings in businesses and homes. To put it simply, business and home owners can observe how much energy is being used on site and then implement strategies to decrease this usage.

There are many benefits to saving energy, including lowering monthly electrical costs and reducing dependency on fossil fuels.

Learn what’s involved in implementing an energy management system.

Factors Involved In An Energy Management System

Monitoring Energy

Energy usage can come from such things as appliances, lights and equipment.

The first step in managing energy is to be aware of how much is being used. You can check your meters weekly or monthly to obtain data regarding your energy usage. This process is rather laborious, however, so a better option is to use interval-metering systems.

These systems automatically record energy usage at specific intervals, such as every 15 or 30 minutes. This data lets you know how much energy is being used at certain times of the day and certain days of the week, which makes it much easier to determine how you can best find ways to save energy.

Controlling Energy

Once you’ve gotten a handle on how much energy is being used and when, you can begin to make changes. You may need to replace old appliances or install time-controlled light switches.

An easy way to lessen energy in an office building is to get employees in the habit of turning off electronics after the workday is completed. You can also install better lighting systems, and replace outdated insulation.

An important way to control energy from heating and cooling systems is to make sure that an empty building isn’t being heated or cooled after workers have gone home, or over the weekend if the offices are closed.

Optimizing Energy

Naturally, when energy is controlled, it is also optimized. However, energy management systems are a process that is ever evolving. It’s important not just to implement measures to lessen energy usage, but also to revisit your usage on a regular basis in order to ensure that nothing has changed.

For instance, sometimes during power failures, heating, cooling and lighting that is on any kind of automated track can reset back to the default. In these instances, you would need to manually reset the system to the desired schedule.

Heat Pump Freezing Up: What Do You Do to deal with a Frozen Heat Pump?

This entry was posted in Heating and tagged , on by .

Heat Pump Freezing Up-What To DoYour heat pump can freeze up any time of the year, not just during the cold winter months. Under normal operation, frost develops on the outdoor coils. When the frost begins to build up, the unit automatically shifts into defrost mode to melt the frost.

If this defrosting mechanism malfunctions, ice can build up to a point that the heat pump freezes and ceases to function.

Learn what you can do and when a qualified HVAC tech is needed.

What You Can Do If Your Heat Pump Is Freezing Up

Sometimes the unit itself is not the problem. One of the first things you can do if you notice ice buildup is to see if the water is coming from an external source. A leaky gutter above the unit or freezing rain can cause ice buildup that blocks airflow past the coils.

Blocked air vents, clogged air filters, and debris build up around the unit may restrict airflow. Clear away all debris surrounding your outside unit and move any items inside the home that are blocking your air vents. Change the filters every few weeks or months according to the manufacturer’s specifications.

What An HVAC Tech Should Do If The Heat Pump Freezes

A qualified HVAC technician can troubleshoot a more complicated problem with your frozen heat pump.
In some cases, water accumulates inside the condenser because of the slab underneath the unit shifts or settles. A technician can offer solutions for improving drainage.

Technicians can check the unit’s automatic defrost controls for faulty or worn components. Repairs may include replacing a faulty sensor, thermostat, defrost relay or reversing valve.

Your heat pump is vulnerable to icing if the refrigerant level drops too low. If this is the case, the technician will have to determine the source of the leak and repair it before refilling the system with refrigerant. Technicians must be certified by the EPA to work with refrigerants, so this is definitely a task you cannot do without help from the professionals.

Rely On The Heating And Cooling Experts

Ice build-up on your outdoor unit is the most obvious sign when your heat pump freezes up in winter or any time of the year. You can rely on the experts at Bruce’s Air Conditioning & Heating to offer effective and affordable solutions for all your residential HVAC system maintenance and repairs.
