What You Should Know About Two-Stage Cooling

What You Should Know About Two-Stage CoolingNo matter what temperature you set your home to, a traditional air conditioner has only two settings: on, and off. A wide range of cooling temperatures is achieved by the thermostat simply turning the A/C off once the temperature is reached, and turning it back on when the house warms up a little. While this works, it can produce intermittent noise and some temperature swings, and it’s not the most efficient way to handle matters. Two-stage cooling is an improvement.

With two-stage cooling, the air conditioner’s compressor has two speeds: high and low. During cooler days, the compressor can run at a lower speed, expending less energy to run while also running more consistently. Less on-and-off noise makes it through your vents, and the temperature remains more stable.

On those scorching Peachtree City days, though, the A/C can switch into high gear to meet the increased cooling load. That way, your air conditioner can always be ready to deliver the amount of cooling you need.

A two-stage cooling system also pairs well with a variable-speed fan, and many are sold combined. Like your compressor, a traditional central A/C fan can only be on or off, cycling air through your ductwork or not. A variable-speed fan, however, can dynamically adjust just how much air is being circulated, further smoothing out the temperature curve in your home.

Yet another benefit of this more-constant air circulation is the fact that most air cleaners require air to be circulating to be cleaned. Your HVAC air filter, as well as UV lights, electrostatic air cleaners, or HEPA filtration devices can only work when air is passing through. That means that two-stage air conditioners and variable-speed fans won’t just keep you more comfortable, they can actually keep you healthy, as well.

It’s Hard to Say Goodbye — When It’s Better to Purchase a New A/C

It's Hard to Say Goodbye -- When It's Better to Purchase a New A/CIn Georgia, an A/C is a necessity. We know how it works, how to maintain it, and maybe even how to fix it. But there are times when it’s better to go ahead and purchase a new A/C. By clinging on to an older model A/C, you may be paying more in energy costs than you realize. Fortunately, there are some easy indicators of when it’s time to say goodbye to your old A/C:

  • Your current A/C is older than ten years old. Newer models can deliver the same or better cooling with significantly less energy use.
  • Utility bills are getting outrageous when the A/C is on. Although power costs are going up, if you start to see usual spikes in your utility bill, it may be time to investigate your A/C.
  • Your A/C is no longer keeping the house cool. There are several reasons your A/C may not be keeping the house cool, but if it’s older than ten years, it is normal for an A/C to loose some efficiency with age. The loss can be kept to a minimum with proper maintenance.
  • Your A/C is breaking down and needing frequent repair.  As the A/C reaches the end of its service life, the compressor can be unreliable, and parts begin to wear out or break. No one likes their comfort to be interrupted on a hot day, and repair bills can add up quickly.
  • Your A/C can’t deal with your home’s humidity. If you often see condensation on your windows, or your home struggles with mold, mildew, and fungus, it may be time to purchase a new A/C system. Consider one with two-stage cooling capability. Two-stage cooling compressors are able to run longer and more efficiently pulling more humidity out of the home.

If it’s time for you to say goodbye to your A/C, contact Powers Heating & Air. We’re happy to help.
