If you own an aging home air conditioning unit, you may have noticed a decrease in its effectiveness. Like all technologies, air conditioners undergo constant redesign and development to enhance features and efficiency. That is why contemporary ACs are far superior to their older counterparts in several ways. However, it isn’t always easy to know when to replace an AC unit, and many variables, such as requirements and affordability, come into play.\u00a0<\/p>\n

Let’s examine the key differences between new and older ACs, which will give you clues about whether it’s time to upgrade to a more modern unit.\u00a0<\/p>\n

7 Differences Between New and Old Air Conditioners<\/h2>\n

No matter how well you care for your old air conditioner unit, it will eventually become outdated and need replacing. While there is no definitive life span for ACs, most sources agree that a well-maintained system can provide good service for 10 to 15 years.\u00a0<\/p>\n

Air conditioners continue to evolve, so if you have an older model and are shopping for a replacement, you will notice the following differences:\u00a0<\/p>\n

1. Modern AC Units Are Sleeker and Smaller<\/h3>\n

AC Units have improved in many ways over the past few decades, but one of the most noticeable is their aesthetic design. Gone are the days of large, clunky AC units. Most modern ACs are sleek and small, intended to blend in with their surroundings rather than dominate a space through their sheer bulk.<\/p>\n

2. They Are Kinder to the Environment<\/h3>\n

Modern AC units no longer use R-22, a refrigerant the government is phasing out due to its ozone-destroying qualities. The refrigerant used in new AC units works better and is less likely to damage the atmosphere. On top of this major change, modern AC units are generally built to be more energy-efficient than their older counterparts. This saves you money on energy bills and keeps CO2 out of the air.<\/p>\n

3. Homeowners Have More Options Now<\/h3>\n

Do you wish your family members could each have rooms at the temperatures they desire so that you can all stop fighting over the thermostat? No problem. Just get a few ductless mini-split AC units. Want an air conditioner that can also work as a heater in the winter? HB Home Service Team has got you covered<\/a>! With advanced technology comes infinitely more customizable opportunities. That is why you’re much more likely to find your perfect AC unit now than 10 years ago.<\/p>\n

4. New AC Units Are Quieter Than Older Models<\/h3>\n

Advancements in technology and improvements in fan blade design mean modern AC units run much quieter than older models. They are designed with noise reduction in mind and incorporate innovative compressor technology and noise-reducing air vents to cool your home quietly.\u00a0<\/p>\n

5. Smart Technology Is Often Included<\/h3>\n

Old AC units are often manually controlled using a simple thermostat or mechanical switches. In modern homes, everything from the garage door to the lighting can be controlled centrally. Modern smart ACs are no different, and many models include Wifi connectivity, allowing homeowners to control the temperature and monitor energy usage remotely from a smart device.\u00a0<\/p>\n

6. New ACs Feature Improved Air Filtration<\/h3>\n

The primary purpose of older-model AC units was to remove heat from inside your home and blow cold air back in without much focus on air quality. Although most contain air filters, they are often basic and less effective than modern ACs. \u00a0Newer models often include advanced air filtration systems that trap pollutants and allergens and improve the air quality<\/a> inside your home.\u00a0<\/p>\n

7. Easier Installation and Maintenance<\/h3>\n

Older AC models were often heavy, cumbersome and awkward to install. Installation and maintenance require more effort than modern ACs, which are generally easier to install and include user-friendly maintenance features such as easy access to filters. Many even have built-in self-diagnostic capabilities, making it simpler to keep them in perfect working order.\u00a0<\/p>\n

Are New AC Units More Efficient?\u00a0<\/h2>\n

Yes! New air conditioners are significantly more efficient than older models. Better designs that consider environmental impact and technological advancements have resulted in slick new AC units that deliver improved cooling performance and substantial energy savings.\u00a0<\/p>\n

The table below provides a snapshot of the main features contributing to new vs. old air conditioner efficiency.<\/p>\n
