The National Institute of Standards and Technology (NIST) conducted research regarding the efficiency of heating and cooling systems. As explained in the results of the study, NIST was the first organization to evaluate the links between poor installation and the system’s efficiency. The head of the study, Piotr Domanski, stated that, “Our measurements indicate that improper installation could increase household energy use for space heating and cooling on the order of 30 percent over what it should be.”
The most common error revealed in the study was faulty, leaking air ducts, followed by restricted airflow and improper refrigerant undercharge. Other factors contribute to poor performance as well in different types of equipment like heat pumps and air conditioners. Essentially, simultaneous defects give rise to increased energy expenditure.
Regular maintenance is significant in avoiding huge electricity bills and unexpected repair expenses. Administering simple DIY techniques like cleaning and replacing air filters of your heating and cooling system regularly can decrease energy consumption by almost 15%. For the summer season, people tend to use air conditioners more often; therefore, it is advisable to change filters at least once a month.
The area where a piece of equipment is placed should be cleaned too, as accumulation of leaves, dust, and other particles can block air ducts and may cause health problems for the occupants. In addition, the impeded airflow would result in equipment inefficiencies, and thus a corresponding increase in energy consumption as people would tend to make adjustments to the system’s controls.
Aside from these DIY strategies, tapping the services of professional Edina heating and cooling maintenance annually is most helpful. Ideally, technicians such as those working at Air Quality Services would disassemble the equipment in order to clean its interiors and moving parts, an aspect where DIY techniques would not suffice. Have your drains checked and unclog them, if necessary. Keep in mind the condenser fan as well, and have it cleaned together with the fan blades to ensure fresh and cool air.
For older equipment that is past its lifespan, replacement should be done immediately. Consult with specialized Minnetonka Heating and Cooling companies to find the most suitable systems for your home, and make sure that these prospective installations are energy efficient as well.
