What To Consider Before You Buy A Room AC
Central air conditioning is probably the best and most convenient choice for some situations, but they do come with a few setbacks. Not only are they considerably more expensive, but they also require professional installation.
Therefore, if you think you could survive by simply cooling one room in the house, perhaps the one used most frequently, you should consider the advantages of a single room air conditioner. Of course, there are many different types and specifications. And because getting the perfect match is our goal, this is going to require some enlightened shopping around. It is advisable to listen to the HVAC contractor on what to consider before buying a room AC.
Types Of Room Air Conditioners
The type of room air conditioner you will need is going to be affected by how much installation work you are prepared to do. If you are a homeowner this will require choosing the best spot, but if you are a tenant, you may need to get your landlord’s OK on these plans.
Air Conditioner Types
- Window-mounted unit – this is the most popular option but will require some renovation work.
- Portable air conditioners – can be moved about easily and connected to a window to expel hot air.
- Split ductless or mini air systems –– these can tend to cost more than your average room air conditioners, but they are also less intrusive and especially quiet.
Be Sure the Refrigerant Is Eco-Friendly
Ozone-depleting R-22 and other HCFCs refrigerants have been replaced with more eco-friendly R410A. TO ensure you get the most from your appliance and it is not retired from use before its service life is complete, be sure that you choose one of the R410A coolant air conditioners.
Deciding On Capacity To Cool A Certain Coverage Area
You should read those manufacturers’ labels to find which of the air conditioners you are considering is powerful enough to cool your room without being too powerful. Either buying an air conditioner that is too small or buying a unit that is too powerful for the room it is cooling will eventually be very energy inefficient. Before you head out to shop, measure the room you will be cooling.
- Smaller rooms between 100-300 sq. ft. will need 5,000 – 6,000 BTU
- Medium rooms between 250-550 sq. ft. will need 7,000 – 8,200 BTU
- Larger rooms will need 350-950 sq. ft. 9,800 to 12,500 BTU’s for
When you see an air conditioner that you really like, check out its coverage area make sure it is a good fit.
Energy Efficiency To Save In Electricity Costs
Air conditioner models that feature the EnergyStar qualifications can save you as much as 30% in energy expense in comparison with those that do not. Additionally, you should look for the energy efficiency rating EER that is given by the Association of Home Appliance Manufacturers (AHAM). The higher the number indicated the better the energy-saving capacity. So an air conditioner with an EER of 11 will use less energy and therefore save more money, than an air conditioner with an EER of 6. Combine a good EER rating with the EnergyStar mark of efficiency and you will have a top rate AC that will cool your room for a nice low cost. Consider the CEE rating as well if you hope to maximize your efficiency.
Benefits Of Portable Air Conditioners
The window or wall-type of an air conditioner is installed seasonally or permanently in the single window where it is being used. On the other hand, there are portable units that can be moved from room to room depending on where they are needed. Some of these mobile units offer a variety of functions like dehumidifying, heating and even air purification, while others just cool the air. Despite their convenience, the portable air conditioner is typically more expensive than the installed unit. Even though they have wheels, some users may find it difficult to move from place to place. But for some situations, they are the best choice.
How Ductless Split Systems Work
Ductless split systems are more efficient than your wall installed an air conditioner, but they will also include some higher costs at the beginning. Like the wall installed unit, ductless split system will need a professional to install correctly. These systems operate with a condenser housed in one section outside, and this is connected to one or two air conditioner units inside via important electrical and refrigerant lines. These are also called mini-splits and are a cheaper alternative to various air conditioners in different rooms.
Installation Considerations For Window/Wall Units
It is important to get the measurements for your windows installed air conditioner perfect. You will also want to consider the implications of losing the corner of the window as well as what you are planning to do with the rest of the space once the portion has been removed. Some people will insert a wooden or plastic panel to cover the rest of the pane.
Some other considerations when installing a wall or window unit is the additional work required to prepare the location and secure the unit in place. There may be some support system that will need to be applied to keeping the unit in place and an off-season cover might need to be thought of before it is really needed.
