3 Benefits of a Variable-Speed HVAC System

Originally published Dec. 13, 2019, updated Jan. 22, 2022

If you’re thinking of getting a new HVAC system for your St. Petersburg, Florida, home, it’s a good idea to opt for a variable-speed model. Unlike a single-speed unit, which always operates at full capacity, a variable-speed HVAC unit can run at different speeds to fine-tune your home’s comfort while maximizing energy efficiency. Below are three reasons why you should consider installing a variable-speed HVAC system.

Improved Comfort

A single-speed HVAC unit runs full blast until it reaches the thermostat’s temperature setting and then cycles off. This pattern of operation can result in uneven temperature distribution throughout your indoor space. A variable-speed system, on the other hand, operates at a lower speed for longer cycles. As such, you’ll experience a more consistent temperature in your home.

Greater Energy Efficiency

Besides making your home more comfortable, a variable-speed HVAC unit can also help you reduce your energy costs. A single-speed system uses more energy because it turns on and off more frequently and runs at full speed. In contrast, a variable-speed model consumes just enough energy to provide adequate power to the compressor. It runs at low speed most of the time and only ramps up when there’s a need for extra output. Therefore, it can prevent energy waste without compromising your comfort.

Longer Service Life

Since it doesn’t operate at full capacity all the time, a variable-speed HVAC system sustains significantly less wear and tear than a single-speed model. Like a car that slowly accelerates, a variable-speed HVAC system starts at a lower speed and then gradually reaches the speed needed for optimal comfort. Additionally, it’s less likely to experience mechanical issues because it doesn’t cycle on and off as often as its single-speed counterpart. Although it comes with a slightly higher price tag, a variable-speed model can help you save money over the long run with its longer life span and lower repair costs.
