5 Things to Consider When Buying an Air Conditioner

Are you looking to buy an A/C unit? If yes, you need to ensure that you get the right one because it is a significant investment. Here is how to choose the right A/C unit.

1. Energy efficiency

Any air conditioner you purchase to replace an ancient unit will result in more energy efficiency. When replacing a central A/C system, be sure both the air handler and the condenser are replaced simultaneously. The two components are designed to operate together. If you fail to change one of them, the system will become inefficient. The Seasonal Energy Efficiency Rating (SEER) is a significant factor in determining the energy efficiency of the new unit. New models are needed to have a SEER rating of at least 14. However, the majority of them have ratings of 15 or higher.

2. Size

Some people have a misconception that the larger the A/C unit, the better their homes will be cooled. But this is not the case, because a big system will switch on and off more frequently, increasing your energy costs. Additionally, it will not operate long enough to minimize humidity. The size of your A/C unit needs to be based on your home’s square footage. Also, you need to consider the cooling load of your house. This can be determined by considering your house size, the amount of insulation, and window size.

3. Cost

If your budget is flexible, there are many considerations to make when it comes to cost. Consider the efficiency of the system and the cost savings you will make both monthly and annually. Moreover, consider the value it adds to your home in the case you plan to sell. Upgrading and including new ductwork might be expensive, but offering your home an excellent central A/C that is efficient and effective can be a significant selling point.

4. Brands

It is always excellent to look for numerous bids when you are looking for a new air conditioner. The unit cost and the setting up is too significant to leave to chance. When you are offered bids, be sure to consider more than the cost. Find out if the companies are known for quality, whether there is a warranty for the unit and labor, if they give a maintenance plan of high-quality, whether they explain the reasons behind them being the best, and if they check your home before offering an estimate.

5. Air Conditioner types

There are two types of air conditioners that you can consider before buying one. The central AC is the most typical type and has an external condenser, ductwork running throughout the house, an indoor air handler with evaporator coils and a blower. The indoor air handler can be set up in a basement, garage, or attic. The other type is the ductless AC, which is an excellent alternative for those who don’t want the ductwork expense.
