Adding a bedroom to your home can be a great way to create more living space and increase your home’s value. However, if you live in a climate like Maryland’s, it’s essential to have a reliable and efficient cooling system in place to keep your new bedroom comfortable during the hot and humid summer months and warm when it is below 40 degrees. In this post, we’ll discuss the benefits of adding a mini split AC unit to your new bedroom addition and provide some tips for completing the installation.


Why Choose a Mini Split AC Unit?

Mini split AC units are an excellent option for cooling a bedroom addition because they are compact, efficient, and easy to install. Unlike traditional central air conditioning systems, mini splits don’t require extensive ductwork, which can be costly and time-consuming to install. Instead, they use a small outdoor unit connected to an indoor air handling unit by a refrigerant line. This means that you can install a mini split AC unit quickly and easily, without disrupting your home’s existing HVAC system.

Another benefit of mini split AC units is that they are highly efficient. Unlike central air conditioning systems, which can lose a significant amount of energy as cool air travels through ductwork, mini splits deliver cool air directly to the room where it’s needed. This means that you can save money on your energy bills while enjoying a comfortable and cool bedroom.

Installing a Mini Split AC Unit in Your Bedroom Addition

If you’re considering adding a mini split AC unit to your new bedroom addition, here are some tips to help you get started:

  1. Determine the right size for your mini split AC unit: The size of your mini split AC unit will depend on the size of your bedroom addition. Be sure to choose a unit that is appropriately sized for your space to ensure that it can cool your room effectively.
  2. Choose a reputable HVAC contractor: Installing a mini split AC unit requires expertise and experience. Choose an HVAC contractor who is licensed, insured, and has experience installing mini split AC units.
  3. Determine the location for the indoor unit: The indoor unit of your mini split AC system can be mounted on the wall, ceiling, or floor, depending on your preferences. Be sure to choose a location that is convenient and won’t obstruct your furniture or decor.
  4. Consider zoning options: Mini split AC units can be zoned, which means that you can control the temperature in different areas of your bedroom addition separately. This can be especially useful if you have a larger space or if there are areas of your bedroom that get more sun exposure than others.
  5. Schedule regular maintenance: Like any cooling system, mini split AC units require regular maintenance to ensure they are working effectively and efficiently. Be sure to schedule regular maintenance with your HVAC contractor to keep your system running smoothly.


Adding a mini split AC unit to your bedroom addition in Maryland can be an excellent way to keep your new space comfortable and cool during the hot and humid summer months. By choosing the right unit size, hiring a reputable HVAC contractor, choosing the right location for your indoor unit, considering zoning options, and scheduling regular maintenance, you can enjoy a comfortable and energy-efficient new bedroom.
