The Environmental Benefits of R-410A:
Most Air Conditioners and Heat Pumps sold around the world use a refrigerant called R-22. Emissions of R-22 are considered by some experts to be a significant factor in depleting the ozone layer that protects animals and people from harmful rays from the sun.
Homeowners and business owners now have the choice to ask for an Air Conditioner or Heat Pump that uses a more efficient and environmentally friendlier refrigerant called R-410A when buying a new system for their home or office.
By selecting R-410A you eliminate the possibility that refrigerant leaking from your system might contribute to the hole in the ozone layer, and you'll also be investing in a comfort system that will last you for many years to come.
The Cost Benefits of R-410A:
With R-22, you run the risk that it could become much more expensive or difficult to get when your system needs to be repaired in a few years. Keep in mind, R-22 will be phased out along with other ozone depleting chemicals, and both supply and demand of this chemical will be significantly affected by current and upcoming regulations.
By selecting an air conditioner or heat pump that uses R-410A, you will avoid the risk associated with purchasing a product that is destined to become obsolete.
R-410A Systems Can be More Reliable than R-22 Systems:
R-410A air conditioners and heat pumps are today's "state of the art" systems, and utilize the most current technology available for efficient and reliable operation.
The heart of every air conditioner or heat pump is the compressor, and newer systems are specifically designed to use R-410A refrigerant. They often incorporate smaller, heavier-duty "scroll-type" compressors that are quieter and operate with less damaging vibration than older compressors that operate on R-22.
Since R-410A can absorb and release heat more efficiently than R-22 ever could, compressors with R-410A run cooler than R-22 systems, reducing the risk of burnout due to overheating.
R-410A Uses a Synthetic Lubricant to Keep Things Moving Smoothly:
All air-conditioning systems use an oil that circulates through the inside of the system to keep all of the parts well lubricated, just like the engine of your car.
R-22 air conditioners use an oil known as "mineral oil" that has been used for decades. R-410A air conditioners use newer synthetic lubricants that are usually more soluble with the R-410A than the old mineral oils are with the older R-22 refrigerants. This means the synthetic lubricants and R-410A can mix and circulate more efficiently to keep the compressor and other moving parts lubricated, reducing wear and extending their life.
Also, just as many new cars use synthetic oils because they are less likely to break down under high stress and heat, the new synthetic oils used in R-410A air conditioners are less likely to break down under extreme conditions.
Why is my air conditioner freezing up?
There are several things that can cause your HVAC system to freeze up, most of them usually need to be corrected by a professional technician. Making sure the filter is clean or replaced and making sure the airflow is not restricted are about the only things you can check or handle yourself.
Low refrigerant: In some cases, freezing up is caused by a leak in the refrigerant lines. Weak solder joints, friction from piping rubbing or vibrating against an object, leaking valves or loose fittings can cause leaks. The age of the system and the nature and location of the leak are the determining factors on whether to have the system repaired or replaced.
Dirty evaporator coil: Over time, the evaporator coil will become dirty. When this happens, the results are similar to those of having a dirty filter. Gradually you will lose airflow, slowly enough that you probably would not realize it until it freezes up or is not cooling adequately. You will need to contact your local Service Experts sales and service center to correct the problem.
Defective blower motor or relay: A blower motor not running at the proper speed or not running at all can cause freezing. It can also be intermittent, starting at full speed and slowing down after it heats up. Or a relay could cause it to start one time and not the next. In either case, you will need to contact your local Service Experts sales and service center to correct the problem.
Should you find that your system was freezing due to a dirty filter, after replacing or cleaning the filter, you can speed up the thawing process by turning the system off and turning on the fan. If you have a heat pump system, you can try turning the system to heating mode until the ice has melted. After the ice has melted, switch the system settings back to normal. If the system refreezes, contact us to correct the problem.
What is a variable-speed furnace?
The term "variable speed" refers to the furnace's indoor air blower motor. The blower motor is the component that determines the amount of air the blower is required to deliver to your home.
When your furnace is installed, the speed and airflow for your home are set depending upon your specific situation, such as the size of your home, etc. However, there are situations that can occur within the household to restrict this airflow, such as ductwork design, unit location, zoning and dirty filters, to name just a few. Think of variable-speed technology as your insurance for home comfort the way you prefer it. Variable-speed technology ensures that your home receives the amount of air required to keep you and your family comfortable. Variable-speed motors have intelligent technology that monitor incoming data from the blower and adjust accordingly so you can feel confident that your system is working to keep you comfortable.
Having the technology of variable speed in your furnace offers many benefits:
Electrical efficiency: Variable-speed motors can actually save you money on your energy bills as they consume less electricity than standard motors.
Cooling efficiency: Variable-speed technology also means you will gain air conditioning efficiency or SEER.
Zoning: Variable-speed furnaces are excellent for zoning, where you control the conditioning of your home. Zoning allows you to customize your comfort in different areas or zones in your home and control your energy bills.
Air quality: A variable-speed motor combined with a humidistat allows you to control the humidity in your home. Humidity plays a big role not only in the comfort of your home, but also in its air quality. The relative humidity in your home should be between 30 and 60 percent. This range is most ideal to minimize growth of biological pollutants such as mold and mildew. The consistent airflow of the variable-speed motor also helps to improve air filtration.
Two-stage heating has many advantages:
Consistent comfort: Thanks to two-stage technology, the temperature inside your home should vary only a couple of degrees versus the larger temperature swings that are common with traditional furnaces.
Quiet comfort: Because a two-stage furnace starts in its first stage, when the amount of heat required is lower, and runs in this stage about 80 percent of the time, it greatly reduces the noise associated with furnaces that turn on and run full blast. Two-stage technology means quiet comfort.
Improved air filtration: A two-stage furnace provides more consistent airflow and with more consistent airflow comes improved air filtration, which means you'll breathe easier with two-stage heating.
Efficient operation: Because the furnace spends the majority of its time operating in its lower-capacity first stage, it burns less fuel than a traditional furnace that always runs at full capacity and then shuts off when the heating demand has been met.
Although you can't see the air and temperature within your home, you can certainly feel them. A two-stage furnace can provide preferred comfort within your home despite the changes in weather outside your home.
Your local Service Experts sales and service center can show you additional benefits of owning a two-stage system.
Whole-house humidifiers work like old-fashioned room humidifiers: They put moisture into the air, making harsh, dry air easier to breathe. And whole-house humidifiers use water mist instead of hot steam, which keeps the entire house at the desired humidity level no more carrying a humidifier from room to room in the winter.
