Top Ways to Get Better HVAC Energy Efficiency

Many people are looking for ways of reducing their energy consumption, and the first suspect for most people is the number one consumer, HVAC. In order to save on your energy costs, you will need to have an efficient HVAC system in place. There are some people who have HVAC systems that account 60 percent of their energy usage. Working on the efficiency of your HVAC system will make a big difference. Below are some great ways to get better HVAC Energy Efficiency. Applying the tips will go a long way in helping you improve the efficiency of the system and lower your energy costs.


There are different reasons why you should consider retrofitting. Some of them include; moving to a new location, looking to improve energy efficiency and comfort, buying time before getting a new system, or when tired of fixing an old unit.

Systems that should be retrofitted are those that are energy intensive, well-maintained, large systems that are used a lot. The Department of Energy found out that you can easily make savings of up to 35% every year in energy costs by adding and replacing parts. Both the heating equipment and air conditioners can be retrofitted. Some common methods of retrofitting include; adding condenser fan controls, replacing the compressor, adding demand-controlled ventilation, and adding air-side economizers and switching from freon to TdX20 from

Programmable thermostat and controls

There is a good chance that you have forgotten to turn down the thermostat when no one in the office at least one because everyone does it sometimes. A good way to deal with this is by having an automated system that will be controlling the thermostat and lights. This will help in increasing HVAC energy. You can set the systems to fit in your schedule. You should also consider replacing older lights with more energy efficient options because it will help you in saving power.

Investing in energy efficient HVAC equipment

When you replace a system that is over 10 years old, then you can expect to get a double or triple return on the investment. Newer models are better because they have a higher SEER rating, which means it has more HVAC energy efficiency. The SEER rating today is between 14 and 18, which is a big improvement from systems from a decade ago. You should also be looking out for the Energy Star rated models, which follow very strict guidelines.


If the building has been poorly insulated, then you can end up losing a lot of air that has been conditioned. You should increase the efficiency of the HVAC system by trapping in all the air (as well as cooled or heated air) being produced. You should also add insulation to the windows and walls. Some other suspects of energy loss include pipes, ducts, and outlets. Wrapping them in insulation will help in saving energy.

Preserving airflow

Another way of improving the efficiency of the HVAC system is by ensuring it is clean and clear of leaves, debris, and dust. You should also ensure that the dents and ducts have not been blocked by the furniture. The AC unit will be able to perform more efficiently when airflow is preserved.

Vigilance about maintenance

Having regular maintenance will help in keeping the equipment running efficiently and making the HVAC system increase its efficiency. You should make sure you keep the appointments for seasonal maintenance, which is usually at the start and end of the cooling and heating season (The frequency of the maintenance will mainly depend on the usage). Maintenance will prove to be far much cheaper than repairing, which will come with a lot of disadvantages.

Tweaking the thermostat

You will notice that people do not complain about the heat when the temperature has gone up by just one degree. This is because many people are not able to notice any change when it is between two to three degrees Fahrenheit. It is a good idea to set the thermostat at a temperature that is closer to that of the outside. This alone can save you a lot of money, and it will also result in increased HVAC energy efficiency.

When the outside temperature is hot, a system that is set to 75 degrees will use 18% more energy than that set at 78 degrees. And when it is at 72 degrees, then you can expect it to use 39% more energy than when it is on 78 degrees. When you don’t have people inside the house, you can turn the temperature up. When you have a programmable thermostat, then you will have an easier time adjusting the settings.

Changing air filters

Blocked air filters are known to cause efficiency issues of HVAC systems. When there is clog in the filter, the equipment is forced to run for a longer period of time and ends up using more power. Filters are important because they will trap the dust before it gets inside the system and cause damage. When there is a filter clog, the dust will start collecting on the fan blades and other motor parts, which will result in slowed down unit, causing waste in electricity.

Power down electronics

You should turn off electronics like computers, exercise equipment, machinery, and media systems when not in use. This is because it will generate less heat and also consume less energy. The AC will have an easier time cooling your home. Even when not using it, electronics tend to draw electricity when plugged in. Combining HVAC and overall energy efficiency will leave you with cheaper power costs.

Switching to a VRF HVAC

Variable Refrigerant Flow (VRF) is a great option for upgrading your HVAC. This is because these systems will heat and cool, and in some cases at the same time in different parts of the same building. When this is done, it means the unit is not using more energy than needed. The compressor will be running at the capacity needed, making it energy efficient. It is important for people to know how to increase their HVAC efficiency because it will result in better results and lower energy costs.
