5-Keys To Replacing Your AC System

If your air conditioner needs service, it might be time to consider replacing it instead of throwing good money after bad. Depending on the age, efficiency, and condition of your AC, often times it make better sense to invest the money you could spend repairing your old system into replacing your air conditioner. Replacing your AC will mean lower utility bills and improved comfort in your home.

The average life expectancy of an AC is approximately 15–years, so it’s crucial you make the right decision, otherwise you’ll end up living with it for many years.

Key-1 Substance Over Status: The brand of air conditioner you buy is important, but it’s definitely not the most important factor. The manufacturer is not the one who is going to install it or service and support you through the years. The company you hire, plus the standards they follow to install your air conditioner are what’s critical, because that's what really impacts your true cost of ownership over the long haul.

Key-2 Size Matters: Nearly 1-out-of-2 air conditioners are over-sized, meaning they are simply too big for your
 home. When it comes to your AC size, bigger is definitely not better. Over-sized systems cost more to buy and operate. A professional “load analysis” of your home is crucial, especially if you’ve made alterations or home improvements since your air conditioning system was originally installed.

Key-3 Blow Hard: Airflow through your air conditioner is how cooling is delivered to your home. Improper airflow means your AC cannot do its job efficiently. Energy Star indicates that 70% of air conditioning systems suffer from airflow issues. “Low Flow” translates directly into decreased cooling capacity and increased utility costs. A thorough analysis of your ductwork is required to ensure your replacement air conditioner will deliver the comfort and efficiency you expect.

Key-4 Tight Is Right: After ensuring the proper airflow, it’s vital to make sure your new air conditioning system is not connected to leaky ductwork. If your supply ductwork leaks air you just paid to cool before it actually gets delivered to your conditioned living space, you end up paying for something but not actually getting it, and nobody likes that! If your return ductwork leaks air from a hot, humid, nasty, dirty space like your attic or crawl space, you end up lowering the air quality in your home by introducing contaminants into your system. Plus, it costs way more to cool hot, humid, nasty air, than it does cooler, cleaner air from your home. The average duct system leaks 30% of its airflow, meaning you could be potentially cooling the outdoors if you’re not careful.

Key-5 Take Charge: Your new air conditioning system will use a modern, environmentally friendly refrigerant. Energy Star studies show that 74% of systems are incorrectly charged. Precise charging of your AC system is required to achieve optimum efficiency and performance. A slight under or over charge will have a dramatic negative impact on system SEER ratings. Professional system commissioning is essential to air conditioner replacement.

A successful air conditioning system replacement starts with a professional consultation to learn about your goals & objectives, survey your entire home, inspect all units & ductwork, and perform a series of engineering checks to ensure your new system is properly sized with adequate ductwork, then provide you with multiple options that include best practices to ensure guaranteed performance.
