There was a time when HVAC was simple. A furnace heated your home. An air conditioner cooled it. And just about everybody had one of those round, dial-a-temperature thermostats that were so easy to use.
Technological innovations in heating and cooling have changed the game quite a bit. Today there are more options than ever before:
Standard, medium and high efficiency models
All electric, dual-fuel, ductless or geothermal comfort systems
Smart, programmable thermostats that “learn” how to control your comfort
Communicating systems that “talk” to you or your dealer via the internet
Remote setup, control and monitoring from virtually anywhere using Wi-Fi® and a connected smart phone, tablet or computer
VARIABLE SPEEDS, MULTIPLE BENEFITS
One of the innovations that plays a major role across all of the above is variable-speed technology. More and more systems today are available with variable-speed technology, and there are a number of reasons why they are so appealing:
Most of the higher efficiency heating and cooling systems today achieve their ratings with variable-speed technology. These systems can save money on your utility bills, and some may even qualify for local utility company rebates. Here’s how:
Variable speed systems are able to run their heating or cooling cycles nearly continuously on lower speeds, thus using less electricity
Single-speed systems actually waste energy turning on and off more often, and running at full speed when they are on
2. CONSISTENT COMFORT
Going back to how variable-speed technology works, the longer heating or cooling cycles help keep the air in your home consistently closer to the temperature set on your thermostat. This results in more even, consistent comfort, with fewer hot spots and cold spots in the house.
In comparison, single-speed systems turn on at full blast to reach the right temperature, then shut off when the temperature is met. When the temperature drops, the system turns on again and the cycle continues with up and down temperature swings.
3. ENHANCED HUMIDITY CONTROL
In the summertime, humid, sticky air can sometimes make you more uncomfortable than hot temperatures. While all central air conditioners remove a little humidity from indoor air during the cooling process, some do a better job than others.
Variable-speed systems are much better at humidity control than standard, single-speed systems. Because they are operating for longer periods of time, they can remove more moisture from the air, so you FEEL more comfortable.
4. IMPROVED AIR QUALITY
All indoor comfort systems have some sort of air filter, typically in or near the indoor air handler unit. Because systems with variable-speed technology run nearly continuously, the air inside your home is being filtered nearly continuously. The result: cleaner indoor air.
