energy efficient Centralized Air Conditioning

People generally buy or use air conditioners without understanding their designs, components, and operating principles. This can cause higher energy consumption and larger energy expenses or unpredictable costing. According to the Department of energy, using central air conditioning can make up over half of your total utility expenses. Many factors affect how efficient your AC is and how much power it will consume. It includes age and condition of the unit, the layout of your space, design of the air ducts, how air-tight space is, and weather conditions, making it difficult to predict exact expenses. It is important to understand different parts of your HVAC unit so that you can use it efficiently and can keep your system in top working condition for when you need it the most. MG COOLING SOLUTION, an HVAC enterprise working persistently to provide better guidance, maintenance, and cooling solutions that are more energy-efficient and suitable according to your heating/cooling needs. A central air system’s energy efficiency is measured in two ways.

  1. The energy efficiency ratio (EER), it describes the unit’s energy consumption while cooling a prescribed volume of 95 degrees of air for an hour.
  2. The seasonal efficiency ratio (SEER) describes the average energy use at various temperatures and humidity levels.

For some, efficiency is the top priority to reduce cooling costs. If you use a central air conditioning system, make it more energy efficient by performing a few chores. Here is the list of few tips that can help you to save money and reduce the chance of a problem developing with your system.

  1. Turn it up one degree, setting your thermostat just one degree above where it would normally be, helps your centralized AC run less frequently and use less power
  2. Use a smart thermostat and program a schedule, thermostats are designed with energy-saving in mind. A thermostat with a programmable schedule sets your AC to not cool when no one is in space and you can also control the temperature remotely.
  3. Keeping ducts clean and airflow clear will help your centralized AC to use less power as it is not struggling against dirty vents and blocked airflow. Make sure that vents or airflow is not blocked by furniture or room layout.
  4. Schedule regular maintenance visits, it helps your unit to maintain up to 95% of its original efficiency. Cleaning the components, fixing electrical connections, and replacing worn parts increase its efficiency and lower down energy consumption.
  5. Changing the air filter, blocked, or dusty air filter can cause increased power consumption and slow your system down. AC technicians will change your filters, depending on your system usage.
  6. Insulate to keep cool air in, if you don’t let the cool air escape you will get the most out of your energy-efficient centralized AC. Insulation is an important step in reducing AC power consumption, HVAC components like pipes, ducts, and outlets are some of the spots for extra insulation.
  7. Retrofit AC unit, you can reduce your centralized AC power consumption by adding more ventilation, condenser fan controls, or replacing the compressor.
  8. Sealing and insulating air ducts, 10% to 30% of conditioned air escapes from the ducts. For a centralized air conditioner to be energy efficient, ducts must be airtight.
  9. Replace your old central air system if it’s more than 12 years old with a newer more energy-efficient star model. According to energy star reports, newer models can reduce 30% of energy consumption used to cool your space.
  10. Invest in energy-efficient HVAC equipment, switch to a VRF (variable refrigerant flow), these systems provide simultaneous cooling/heating in different parts of the same building. The compressor has variable speeds and only runs at the capacity it needs, which makes your central air system more energy efficient.
  11. Use curtains and blinds, it prevents unnecessary heat coming from outside during hot summers, so your central air system works less to maintain a cooler temperature and consume less energy.
  12. Place the unit in a shaded area, if your unit is placed in an area with excessive sunlight, the system will overheat and consume more energy.
  13. The right size system, having a system that is either too small or too big for your space may cause unnecessary energy usage. Taking professional advice will help you to choose an energy-efficient central air system.

From the type of system, you have to know how well it is maintained and can all affect its energy efficiency, even a small change can help make it more energy-efficient. Proper care, vigilance, and time to time maintenance of your central air system will reduce your overall power consumption cost and increase the life of your system.
