Remember to always have a licensed installer assure what is right for your home.Choosing an Air Conditioning System Selecting an air conditioner for your home is a big decision. It’s an important investment today. It will play a key role in your home energy expenses for years to come. And when the summer heat is at its worst, you’ll want your family to have the best, most reliable cooling comfort possible. Here are a few things to consider. What do good central air units have in common? How can I be sure my Unit is the right size? Which air conditioners are energy efficient? Are some air conditioners built better than others? What should I look for in a contractor? The best ones are efficient, operating on minimal electricity to hold utility bills down. They provide steady, dependable performance year after year when properly maintained.

Good systems are quiet, long-lasting and low in service needs. Back to the topmaintenance of an ac unit Obviously, an air conditioner that’s too small won’t keep your home sufficiently cool. used ac unit for mobile homeBut what many don’t realize is that an oversized system will cycle (turn on and off) more than necessary, wasting expensive energy and possibly putting undue strain on the compressor.ac unit outside not turning on A good contractor will determine the optimum size for your home by making a careful study of your cooling requirements. Window dimensions and exposure. Floor space, insulation and local climate. The direction your home faces. Even the amount of your home’s exterior shaded by trees. He’ll specify the cooling capacity of the system in either Btu/h (British thermal units of heat removed per hour) or refrigeration tons (one ton being equal to 12,000 Btu/h).

Much like automobile manufacturers, today’s air conditioner manufacturers are required by law to evaluate and rate their equipment according to its energy efficiency. This rating is known in the industry as a SEER, or Seasonal Energy Efficiency Rating. The higher the SEER, the more efficient the equipment. Most new homes with central air come equipped with a standard builder’s model. However, when replacement becomes necessary, property owners can upgrade their air conditioning by specifying a more energy-efficient system. The Rheem Prestige Series™ High Efficiency model, for example, has a SEER of 18.00, among the highest available. It’s significantly higher than today’s standard models, many of which carry SEER’s of at least 13. High SEER models are generally more expensive, but can easily make up the difference by reducing your home energy bills over the long run. The compressor is the heart of a condensing unit. On a hot day, it works long and hard.

Rheem installs the highly advanced scroll compressor in every Rheem condensing unit we produce. Scroll Compressors are recognized by the industry as the leader in reliability, efficiency and quiet operation. Other features to look for include louvered steel cabinets that protect the coils from damage and expensive repair bills. Also, with some condensing units, the fan can be another source of bothersome noise. Rheem units have a grill design that minimizes air restriction for quieter fan operation.Look for a contractor you see in your community. You want one who’s close by to provide you faster, more convenient service. He should offer a recognized name brand. And he should have a well-stocked inventory of replacement parts. You wouldn’t want to sit out a mid-summer heat wave waiting for a simple repair! One way to be sure you’ll get good service is to contact a neighborhood Rheem contractor. Your local Rheem contractor is knowledgeable, dependable, and as good as any you’ll find in the business.

Back to the topCentral Air Conditioning Unit Size (AC) Determining the Right Central Air Conditioning Size (AC) Air conditioner size is rated using the number of BTU's or British Thermal Units of heat that it can remove per hour. (1 BTU is the amount of energy to raise the temperature of one pound of water by one degree Fahrenheit.) You may also hear ac size referred to in "tons" which is the equivalent of 12,000 BTU's. (12,000 BTU's is the amount of energy required to melt 1 ton of ice in one day.) An average central air conditioner size would be between 3-6 ton or 36,000 - 72,000 BTU's/hr. Note: the size or capacity is not directly related to how efficient an air conditioner is. In order to determine the correct size of central air conditioner for your home you must consider: Age and size of your home How many windows and size of the windows in your home Level of insulation your home has Level of shade that falls on your house walls, windows and roof

Direction that your home faces While the above may seem like overkill it really isn't, here's why. In order for your ac unit to work as efficiently as possible it must be carefully sized to your specific house and environment. Installing an air conditioner that is too small will result in: Increased energy bills since the unit must run additional hours trying to keep up with the heat of the house. A home that is not comfortable since the unit is unable to cool quickly enough to "get on top" of the heat. If you install a central air conditioner that is too large the unit will cycle (turn off and on) too often which will result in: Less humidity being taken out of he air in the house. In a humid climate de-humidification is essential to the temperature feeling comfortable. Less consistent temperature in the house. More wear and tear on the ac compressor and other parts of the unit.
