Upgrading? Look For These Top Air Conditioning Features

With the summer heat bearing down on Florida, you might be wondering how well your cooling system will hold up for the duration of the season. In fact, you may be looking at new systems right now.



If you’re thinking about shopping, or you’re actually taking the initial steps to replace your system, the first thing you’ll want to consider is the efficiency rating of each unit. An air conditioner’s cooling efficiency is measured in terms of its seasonal energy efficiency ratio. While many older units have SEER ratings as low as 6, all units manufactured today must have a SEER of at least 13. The higher the SEER, the more efficient the equipment. Also look for the Energy Star label.

You will also want to consider various energy efficiency and home comfort features. Among the features you should consider are:

•A dual-stage compressor: A cooling system with a dual-stage compressor runs on high when it’s very hot and at a lower speed when the weather’s milder. On most days, it runs at low speed for a longer time. This means a more even temperature and better humidity control, as well as operation that’s quieter and more energy efficient.

•Thermal expansion valve: This device controls the superheat in the compressor. Used in place of a capillary tube or other fixed orifice device, it helps to ensure that the evaporator coil operates at maximum efficiency, regardless of the outside temperature. It also helps to ensure compressor dependability.

•A fan-only switch: You can use this for nighttime ventilation when the temperature’s moderate.

•A filter light check: This will remind you that it’s time to change the filter.

Unfortunately, the best system in the world won’t give you the economy and comfort you want if it’s not sized and installed correctly. Make sure your contractor uses Manual J to size your system. One that’s too big will cycle on and off too frequently, failing to remove sufficient humidity from the air and detracting from your comfort. One that’s too small just won’t do the job.
