Thinking About Getting a New Air Conditioner? Top Features of Modern Systems

AC systems can last for years, but it’s not always the right move to hold onto an older model. A new air conditioner delivers increased performance and requires fewer repairs, but that’s not all. Modern systems also incorporate a variety of technologies to provide even more benefits.

Inverter Technology

Many new HVAC systems feature inverter technology that allows for variable-speed operation. These systems convert AC electricity to DC, which allows for the compressor to run at different power levels, not just on or off. Steady operation instead of frequent cycling reduces wear and helps maintain steadier indoor temperatures.

Do Variable-Speed Air Conditioners Last Longer?

In general, yes. Startup takes a toll on compressors, much more than steady operation. Traditional AC systems turn on and off frequently, which leads to serious mechanical stress. By avoiding constant cycling and adjusting speed instead, variable-speed air conditioners can achieve longer useful lifespans.

Improved Efficiency

New air conditioning units are significantly more efficient than older models. Modern systems go beyond just the benefit of being in brand-new condition. Inverter technology, smart controls, and better refrigerants all improve efficiency. That leads to higher SEER2 ratings, which translate to lower utility costs month after month.

What Is SEER2?

SEER2 stands for Seasonal Energy Efficiency Ratio 2. It’s an updated version of the older SEER rating, designed to be more accurate. It measures how much energy the AC uses to cool air based on standardized conditions so that AC units can be compared to each other. New air conditioner models go through testing to determine their rating.

Smart Thermostat Integration

Traditional AC systems didn’t have much more than a single temperature setpoint determined by a simple thermostat. New AC systems have a much wider range of control and communication options, allowing for improved comfort and convenience. The compressor and fan can be carefully dialed in to deliver just the right performance.

Integration with smart thermostats also lets you schedule cooling to save more energy, reducing output when you aren’t home. Wireless connectivity enables you to monitor or adjust your AC from anywhere. Your new air conditioner can even provide valuable data insights to point out any potential issues in the future.

Quieter Operation

Replacing your AC with a newer model can help do away with excessive noise. To start, variable-speed ACs don’t have the loud startup and shutdown that comes with every cycle. Instead of that abrupt noise, there’s a barely perceptible change when the compressor speed changes.

Both indoor and outdoor parts of the system are carefully optimized to isolate vibration. This stops noise from traveling throughout your home. Modern ductwork also goes a long way to help dampen noise from your HVAC system.

Find Your New Air Conditioner

Energy savings, increased durability, quieter operation, and improved control are all benefits you can get from a new air conditioner. You’re missing out if you’re trying to keep an outdated system running. If it’s about time to replace your system, reach out to the team at Southern Air for a full selection of the latest models.

Southern Air is phenomenal! They installed a brand new AC unit and a new air handler for us- they were prompt, efficient, and thorough. The techs disposed of our old equipment, and left our home in pristine condition. When we had an issue related to a power outage once, and they sent a tech out to us within 30 minutes of our call. They offer 10 year warranty options and an annual program, where they will perform all maintenance, even filter changes. I could not be happier with their services, and I enjoy never having to think about the AC! They are the best in Putnam county. Updated to add: I continue to be impressed by Southern Air. Our air conditioner went out late in the evening. Someone from this company answered the phone at 9:00 pm and arranged service for us first thing in the morning. Trenton was friendly and knowledgeable. He arrived promptly as scheduled and diagnosed the issue. I appreciate that they texted a photo of the technician and his name, so I knew who to expect, for safety. Everything was covered under the maintenance plan and warranty, and they even loaned us a temporary air conditioning unit while we wait over the weekend for the parts and repair. I am very grateful. The people running this company are wonderful people that truly care.
Response from the owner:Thank you so much for taking the time to leave us a positive review - it’s greatly appreciated!
