Top Tips for Choosing Central AC in Canal Winchester

According to the U.S. Energy Information Administration, nearly 90 percent of new homes built in the USA include central air conditioning. Air conditioning has become a necessity to control indoor temperatures for those us living in “modern” society, especially for those with allergies or asthma.

Some areas of the country, like the northeast, tend to use window air conditioners, probably because of the milder summer temperatures up there. In the Canal Winchester/Central Ohio area, most of us prefer a whole-house air conditioning system (also called central air).

The reason why most people are opting for this is that the central air keeps the temperature of the entire home at a comfortable level as it filters and dehumidifies the air. It’s relatively easy to install air conditioning in a new build, but you can also add central air in an existing structure.

Following are tips to choose and install the best air conditioning system for your home or business.

Properly sized AC unit

Many people buy an air conditioner that is too large, thinking it will provide better cooling. However, an oversized air conditioner is actually less effective — and wastes energy at the same time. To find the right size, figure the square footage of the area to be cooled. Then, using the square footage and the chart below, determine the correct cooling capacity. Cooling capacity is measured in British thermal units (BTUs) per hour.

Area To Be Cooled
(square feet)
Capacity Needed
(BTUs per hour)
100 up to 150 5,000
150 up to 250 6,000
250 up to 300 7,000
300 up to 350 8,000
350 up to 400 9,000
400 up to 450 10,000
450 up to 550 12,000
550 up to 700 14,000
700 up to 1,000 18,000
1,000 up to 1,200 21,000
1,200 up to 1,400 23,000
1,400 up to 1,500 24,000
1,500 up to 2,000 30,000
2,000 up to 2,500 34,000

You might need to make adjustments for the following circumstances:

  • If the room is heavily shaded, reduce capacity by 10 percent.
  • If the room is very sunny, increase capacity by 10 percent.
  • If more than two people regularly occupy the room, add 600 BTUs for each additional person.
  • If the unit is used in a kitchen, increase capacity by 4,000 BTUs.
  • Consider where you install the unit. If you are mounting an air conditioner near the corner of a room, look for a unit that can send the airflow in the right direction.

Air conditioning units are available in various sizes, rated by BTU, so carefully pick the size that you think would be the best for your home. Remember, that the machine would not be able to properly dehumidify air if it’s too large for its purpose.

Seasonal Energy Efficiency Ratio (SEER)

The next important thing to look into is the Seasonal Energy Efficiency Ratio (SEER) rating. The technology has improved, and energy efficiency has also improved as a result. New air conditioners must have a SEER rating of 13, but a rating of only 7 or 8 was enough for AC units installed a couple of decades ago.

You can actually save quite a lot on your electricity bills if you replace your old and ineffective air conditioner with a new central air conditioning system. In fact, you can expect to save more than $500 a year with the higher SEER rating, which has gone up to 13 from 11.5. To get the latest in energy efficiency, consider a compressor with “Scroll technology”.

The American Council for Energy Efficient Economy recommends a SEER rating of at least 14.5.

Energy Star Rating

The “Energy Star” rating is another criteria which your central air conditioner should have. This is basically a certificate to indicate that the equipment consumes less energy than other models. The new models obviously consume a lot less than the machines dating back a couple of years. See more here.

Energy Star maintains a directory of products that you can browse. Many of the products Pickerington Heating offers are included in that directory.

Location, Location, Location

We all know that’s the mantra for buying real estate, but it’s also relevant to installation of an air conditioning unit’s outdoor component. This is important because it would not be able to ventilate air properly if it is installed under a deck, or is covered up by plants. These units can sometimes be noisy, so keep them far from your deck or your patio, or any place where you want to enjoy quiet. If the unit becomes excessively noisy, give us a call to troubleshoot the problem. It might just need cleaning or routine maintenance.

Air Conditioning Maintenance in Canal Winchester

To maintain your system’s efficiency, consider purchasing a service agreement to receive priority service and regular system checkups. Download a proper maintenance checklist from the 2 Degree Pledge campaign Web site.  The 2 Degree Pledge campaign is an effort by a group of utilities, trade associations and nonprofits to educate consumers about how to optimize their residential heating and cooling systems’ efficiencies, without compromising their comfort.

Tax Incentives to Invest in a New AC Unit

The information below applies to qualified products installed from January 1, 2012, to December 31, 2013. On January 2, 2013, President signed legislation extending the following tax credits through December 31, 2013.

Tax Credit Details for Homeowners:

The efficiency levels required reflect the highest tier of the CEE High-efficiency Specification for Residential HVAC Systems as of January 1, 2009. Please note: Equipment must meet all performance specifications for its category. For example, a tax-credit eligible central air conditioner must have stated performance ratings of 13 EER and 16 SEER.

To sum it all up: by installing a new central air conditioning unit in your home, you’ll be more comfortable, you’ll use less energy, you’ll save money and get a tax credit. What could be better in beautiful Canal Winchester, Ohio?
