Learning the 123’s of Air Conditioning Units
The U.S. Department of Energy reports that six percent of all the electricity produced in the United States is air conditioning use. Regarding individual homes, AC costs account for at least 50 percent of their energy bills. This is billions and billions of dollars spent amongst homeowners each year.
Homeowners should know the basics of their AC system, so they can save money, energy, and frustration. Here are some fast-and-easy things to know:
The Common Types of Air Conditioners
Many homeowners know they have AC units – but don’t exactly know what types they have. Here are the two main types:
- Central air conditioning units: These systems are designed to cool the entire home. Central AC units are extremely common in areas where there’s new construction, and temperatures soar all year long. Most homes in Minnesota do not have central AC units; because of the mild temperatures, they’re not necessary. Many businesses and offices have them, though.
- Ductless air conditioning units: Central AC units rely on a system of ducts in the ceiling. This routes cool air to various parts of the home. Yet, ductless AC units do not have these systems. They draw air from the outside, cool it, then cool usually one room at once. Many people have ductless AC systems, use them during the summer, and uninstall them when fall or winter comes.
Both of these systems come with their own advantages and disadvantages. For instance, while ductless AC units are ideal for older buildings, they’re sometimes pretty expensive to install. Central AC units require annual maintenance, such as ductwork cleaning. Yet, they can cool an entire home and reduce the home’s humidity.
Signs That an AC System Needs Professional Attention
The U.S. Department of Energy notes that, on average, an AC system can last 10 to 15 years. The older one unit gets, the more maintenance it will need. Some signs that an AC unit needs professional attention include:
- Higher-than-normal energy bills: All homeowners should know what to expect when their energy bills come in the mail. If they notice a significant increase in their home’s heating and cooling costs, this could point to a problem with the AC unit.
- The home doesn’t get to the desired temperature: The AC unit must effectively communicate with the thermostat to maintain an ideal indoor temperature. If these systems can’t communicate, this could affect how the AC system functions.
- Strange sounds come from the AC system: If one hears a squealing or squeaking noise coming from their AC system, this could point to a faulty motor fan. This would require an expert’s attention to remedy the issue.
This isn’t a complete list of issues that need professional attention.
How Homeowners Can Maintain Their AC Systems
There are many things homeowners can do throughout the year to maintain their AC units. Some of these measures include:
- Changing the air filter: EnergyStar suggests changing the AC’s air filter once every three months. One should know their air filter’s dimensions before purchasing a new one. Generally, one can get a new air filter for under $20 at the local hardware store. They can also consult a professional for more guidance.
- Keeping the area around the AC unit clear: It’s easy to store Christmas decorations, camping gear, and other items near the AC unit. However, these items can prevent the system from “breathing,” increasing energy bills and lowering efficiency.
- Scheduling an annual maintenance visit: One should schedule annual maintenance visits. An HVAC professional can assess one’s system and render appropriate repairs.
