Choosing or Upgrading Your Home’s Central Air Conditioning System

ac-unitsHomeowners who initially sought Sugar Land air conditioning repair for their home’s failing system may find they need to purchase a new air conditioning (AC) system. Alternatively, they may decide to upgrade their existing system with a new unit that resides outside the home because their unit was not energy-efficient or needed too many replacement parts (and perhaps costly labor). Whatever the situation, investing in upgrading an existing AC system or buying a completely new AC system is a big decision for homeowners. If this is your situation, you will want to ensure that you are getting a good return on your proposed investment.

Different Kinds of Systems

At a minimum, homeowners can choose between two basic kinds of AC systems: split-system units and packaged units. In a split-system unit, there is one unit outside the home that houses the compressor and the condenser and a separate unit inside the home that houses the evaporator. In a packaged unit, all three components — compressor, condenser, and evaporator — reside in the same box located outside the home.

What to Look For

Central air systems help homeowners control energy costs in their home because they offer greater efficiency. The alternative is buying a single room air conditioner for each room. This kind of unit is generally not energy efficient. The loss of efficiency is greater if there are any air leaks where the unit is fitted into the window. Room air conditioners are also loud and may leak condensation on the flooring inside the room. Central air conditioners are quiet and located in an unobtrusive area outside the home.


If you have decided to purchase a central air conditioning unit, there are many things to look for. Choose a unit that is rated for high energy efficiency. A typical home requires more than 2,000 kilowatt-hours of electricity per year. Larger homes need a system that handles a higher demand for cold air.

These tips can help you choose from central air units on the market:

  • Choose the proper size for the AC unit. If the AC unit that you buy is too large, it will not sufficiently remove the humidity in the home. If the AC unit is too small, you cannot cool the house enough during the hottest months for everyone to feel comfortable.
  • Beware of problems that could reduce your AC unit’s efficiency. Consult with the installation technician to ensure the unit is installed in the right location, that there is sufficient insulation, and that all ducts are properly installed. All of these factors, if not correctly accounted for, will reduce the unit’s efficiency.
  • Choose a system that is rated with a seasonal energy efficiency ratio (SEER) of 13 or higher. This has been the industry standard since 2006. This kind of product qualifies for the ENERGY STAR® label.

Various manufacturers market AC systems in the U.S. Some manufacturers work with local companies to directly install their systems and then guarantee their work. The brand you choose may affect the quality of your AC equipment. Purchase a brand that you trust and that includes a proper warranty for parts and labor. Some companies will guarantee some of the major components of their AC system, such as the air compressor, for up to 10 years.

Although you may first consider AC repair in Sugar Land, you can expect a new high-quality system to service your home for 15 to 20 years. For expert assistance with choosing the right AC system or for AC repair in Katy or Sugar Land, please contact All Out A/C and Heating today at 281-238-9292.
