Guide: Single-Stage, Two-Stage, and Variable-Speed Air Conditioners

When it comes to keeping your home cool and collective, there are a variety of air conditioners to choose from when replacing your old AC system. The three main types of air conditioners available to customers are single-stage, two-stage, and variable-speed air conditioners.
Don’t know the differences between the three? No worries. HARP Home Services has you covered with a breakdown of the differences among these air components and how they can best suit your home. Let’s take a look below.

Differences Between Single-Stage & Two-Stage Air Conditioners

The difference between one-stage and two-stage air conditioners falls on the system’s operational speeds: a one-stage compressor is either functioning at 100% capacity or is entirely off. On the other hand, a two-stage compressor is engineered to operate at full capacity or 70% capacity.

A traditional one-stage model will shut on and off depending on your desired thermostat setting. For instance, if you set your thermostat to 69 degrees, the air conditioner will let the home’s temperature get to 70 degrees before powering on. From there, it will cool the interior temperature of your home to 69 or even 68 degrees, and the cycle continues.

On the contrary, the two-stage compressor system is a more efficient choice. This system will work less hard when the temperature is close, using less energy and reducing the constant cycling process.

Differences Between Two-Stage & Variable-Speed Air Conditioners

When it comes to high efficiency, a variable-speed air conditioner reigns overall. A variable-speed AC system can have over 700 distinct compressor settings working with varied airflow levels. Variable-speed air conditioners typically feature a SEER rating of 20 and higher. A SEER rating indicates the efficiency of your system.

Though a two-stage compressor operates at a higher efficiency than a traditional one-stage compressor, a variable-speed unit is top tier and uses only the power necessary to sustain a consistent temperature in your home. We offer emergency variable-speed air conditioning installation and repair services in areas of Connecticut such as Hartford, Waterbury, New Haven, Hamden, and Bristol.
