5 Telltale Signs That You Should Replace Your AC

Air conditioners are no longer a luxury; they are already a must-have for every homeowner. And since we use them every day, they become susceptible to wear and tear. Unluckily, no matter how efficient your cooling units are, they won’t last forever. But when can you tell that your AC is already at the end of its life? Here are tell-tale signs that you already need to replace your air conditioning unit.

  1. Increasing Energy Bills

If you notice that your energy bills are out of control, it could be a sign that your air conditioner is not working efficiently anymore. This is a good time for you to buy a new and more efficient unit. Buying a new AC can significantly slash your month bills.

  1. Your AC is More than 10 years Old

Is your unit already more than 10 years old? If yes, then it’s strongly recommended to replace your existing unit with a new one. Ideally, air condition systems are designed to last for 10 years prior to replacement. If your unit is already on the verge of its lifespan, it’s wise to talk to your local HVAC contractor for replacement.

  1. Poor Indoor Air Quality

You are probably replacing air filters periodically, but time will come that your old unit loses its ability to remove allergens such as mold, dust and pollen inside your home. Musty smell from mildew and mold can be detrimental to your health. Replacing your existing AC with a new unit becomes a life-saver in this situation.

  1. Frequent Breakdowns

Have you noticed that you keep on bringing in a technician to repair your AC? It is probably time to accept the fact that your unit is already beyond repair. Instead of paying for unnecessary costly repairs, replace it with a more efficient unit. Talk to your local HVAC company for replacement.

  1. High Or Low Humidity Levels

If you notice that your become is muggy, it could mean that your C is not properly humidifying your indoor space. Also, if your home is already experiencing mold problems, then you can put the blame on humidity issues. High or low humidity levels at home can be another reason to replace your AC.

HVAC Rating System Jargons And Their Meaning

At Maddox, we want you to enjoy the comfort level you and your family deserve. When choosing your new HVAC system, you could get intimidated due to industry jargons like AFUE and BTU. And you’re wondering what those terms mean. Let’s go over the following HVAC rating system jargons and their meanings.


Seasonal Energy Efficiency Ratio (SEER) is the cooling output during an average cooling season divided by the total electric energy input during the same period. The higher the system’s SEER rating, the more energy efficient it is and the lower your energy cost.


Annual Fuel Utilization Efficiency (AFUE) measures the efficiency of your furnace when it comes to converting fuel into energy. The higher the unit’s AFUE, the more energy efficient it is. AFUE rating may not be available to units that are already more than 15 years old. Contact your local HVAC company for more information.


The Energy Efficiency Ratio (EER) of an air conditioning unit is measured by the output cooling divided by the total electrical power input. EER is ideally determined by a set indoor air temperature, a set outdoor temperature and 50 percent relative humidity.


One British Thermal Unit (BTU) is the amount of heat needed to lower or raise the temperature of 1-pound of water by 1-degree Fahrenheit. BTUs are often used in most AC units.


The Heating Seasonal Performance Factor (HSPF) measures the efficiency of your heat pump. It the ratio of the heat output to the total electrical energy used over a typical heating season. The higher the unit’s HSPF, the more energy efficient it is.
