When it comes to keeping your home comfortable during the hot summer months, air conditioning is a necessity. There are many different types of residential air conditioner units to choose from, but central air units are the most popular. In this article, we’ll discuss what central air units are, what they are used for in residential homes, and what the most cost-effective options are for homeowners.
Types of Residential AC Units
Central AC Units
Central air conditioning is a system that cools the entire house by circulating cool air through ducts. Central AC units are comprised of a condenser unit, an evaporator coil, and a network of ducts. The condenser unit is located outside the home and houses the compressor and condenser coils. The evaporator coil is located inside the home and is responsible for cooling the air. The ducts distribute the cooled air throughout the house.
One of the benefits of central AC units is that they are more efficient than window units or portable air conditioners. They are also less noisy and more aesthetically pleasing since the unit is located outside the home.
Ductless Mini-Split AC Units
Ductless mini-split AC units are a type of air conditioning system that doesn’t require ductwork to cool a room or area. These units consist of an outdoor compressor and one or more indoor air handlers. The indoor air handlers can be installed on a wall or ceiling and are connected to the outdoor compressor via a small conduit.
One of the benefits of ductless mini-split AC units is that they are more energy-efficient than central AC units, which can lead to lower electricity bills. They are also easier to install since there is no need for ductwork.
Considerations When Choosing a Residential AC Unit
Size of Your Home
The size of your home is one of the most important factors to consider when choosing a residential AC unit. An AC unit that is too small will have to work harder to cool your home, leading to higher electricity bills and a shorter lifespan for the unit. On the other hand, an AC unit that is too large for your home will also waste energy and money.
The climate you live in is also an important factor to consider when choosing an AC unit. In hot and humid climates, a more powerful unit may be necessary to keep your home cool and comfortable. In drier climates, a less powerful unit may be sufficient.
When choosing a residential AC unit, it’s important to consider the unit’s energy efficiency. Energy-efficient units can help reduce your energy bills and are better for the environment. Look for units with a high SEER rating, which stands for Seasonal Energy Efficiency Ratio.
The cost of the unit and installation is also an important consideration. While central AC units are more expensive to install than window units or portable AC units, they are more energy-efficient and may save you money in the long run.
The Most Cost-Effective Central Air Units for Residential Homes
Brand New Air Conditioner vs. Refurbished AC Units
When choosing a central AC unit, you may be tempted to purchase a refurbished unit to save money. However, while refurbished units may be cheaper, they may not be as reliable as a brand new unit. Refurbished units may also not be as energy-efficient, leading to higher electricity bills in the long run.
Choosing the Right Size of AC Unit for Your Home
As mentioned earlier, choosing the right size of AC unit for your home is important for energy efficiency and cost-effectiveness. A professional HVAC technician can help you determine the right size unit for your home.
Energy-Efficient AC Units
When choosing a central AC unit, it’s important to look for models that are energy-efficient. Look for units with a high SEER rating, which means they are more energy-efficient. The higher the SEER rating, the more energy-efficient the unit is. For example, a unit with a SEER rating of 16 is more efficient than a unit with a SEER rating of 13.
Another factor to consider is the type of refrigerant used in the AC unit. Older units use a refrigerant called R-22, which is being phased out due to environmental concerns. Newer units use R-410A, which is more environmentally friendly.
Cost Comparison of Different AC Unit Brands
When choosing a central AC unit, it’s important to consider the cost of the unit and installation. However, it’s also important to consider the quality of the unit and the reputation of the brand. Some popular brands of central AC units include Carrier, Lennox, and Trane.
Carrier is known for its energy-efficient units and has a SEER rating range of 13-21. Lennox has a wide range of SEER ratings, from 13 to 26. Trane is known for its durable units, which are designed to withstand extreme weather conditions.
HVAC Maintenance Tips for Residential AC Units
Regular Cleaning of the AC Unit
Regular cleaning of your AC unit is important for its overall efficiency and longevity. Make sure to clean the outside condenser unit at least once a year, removing any debris or leaves that may have accumulated on the unit. Additionally, it’s important to clean or replace the air filter at least once a month.
Changing Air Filters
Changing the air filter in your AC unit is important for its overall efficiency. A dirty air filter can cause the unit to work harder than it needs to, leading to higher energy bills and a shorter lifespan for the unit. Make sure to replace the air filter at least once a month.
Checking Refrigerant Levels
The refrigerant in your AC unit is responsible for cooling the air. If the refrigerant levels are too low, the unit may not be able to cool your home efficiently. Make sure to have a professional HVAC technician check the refrigerant levels at least once a year.
Annual Maintenance by a Professional HVAC Technician
Having your AC unit serviced by a professional HVAC technician at least once a year can help ensure that it is working properly and efficiently. During a maintenance appointment, the technician will check the refrigerant levels, clean the unit, and make any necessary repairs.
Choosing the Right Residential AC Unit
In conclusion, choosing the right residential AC unit is important for keeping your home comfortable and energy-efficient. Central AC units are the most popular type of residential AC unit and come in a variety of models and brands. When choosing a unit, it’s important to consider the size of your home, the climate you live in, the unit’s energy efficiency, and the cost. Regular maintenance and cleaning of your AC unit can help ensure that it is working properly and efficiently. By following these tips, you can find the most cost-effective central air unit for your home and keep it running smoothly for years to come.
