Heating, ventilation, and air conditioning systems take up most of the energy bill in our homes. As a matter of fact, space cooling alone can take up to 15% of the electricity usage at any one given time. The US Department of Energy found that most of the energy that goes into powering HVAC systems is instead wasted. More than 30% of the total energy taken up by these systems ends up elsewhere.
For sustainability of HVAC systems, energy wastage needs to be minimized as much as possible. Surprisingly, many of the steps that managers and business owners can take to enhance sustainability and reduce costs do not require much sacrifice on their end. Below are some of the tips you can easily implement together with your local HVAC technician.
Regular Changing of Filters
This alone can reduce energy wastage by close to 10%. Dirty filters restrict airflow which in turn overworks the HVAC system leading to poor indoor air quality, lots of maintenance issues and costs, and inefficient operation. It is advisable to check your filters at least once in every 3 months and where necessary replace them.
Installing Programmable Thermostats
There is always a contention around temperature settings in homes and businesses. When you install programmable thermostats, you do not need to constantly tailor the temperature settings to meet the needs of your immediate space.
When you install programmable thermostats, you can set your building temperature to correspond to the season and the occupation status of the space. You can get programmable thermostats in 7-day models, 5+2-day models, and so forth. The 7-day models are ideal for schedules that are regularly changing while the 5+2-day models are best suited for businesses that operate on 5 days with the extra two days for the weekend taking lesser energy.
Regular Quality Maintenance
HVAC maintenance is much like getting a tune-up for your car. It is important to maintain your system for top performance. System components that are regularly maintained do not take up much energy because they run efficiently. You can save up to 40% of energy simply through maintenance.
Sealing your heating and cooling ducts can help enhance energy efficiency by 20% or more. The best step is to find a technician who is experienced in duct sealing to help you out. In addition to the sealing, the ducts should be wrapped in insulation.
HVAC Upgrades and Replacements
While the above approaches are recommended to bring your system to an excellent performance level, at times the age of your system may not allow it to perform beyond a given level. The best option is to look for a replacement or upgrading to a higher version.
If your AC is more than 10 years old, find an Energy Star approved system and do the replacement. These systems will save you a lot of energy both in the short and long run.
