Are you a Katy homeowner thinking of buying a new air conditioning system? When investing in an air conditioning system for your home, you want to make sure you invest in the most reliable and efficient system possible. Ductless heating and cooling systems are becoming increasingly popular over the years. Regardless, many homeowners in Katy still don’t know much about this dependable and cost-effective technology. Here are some frequently asked questions about ductless air conditioning systems and their answers:

What Is a Ductless Air Conditioning System?

A ductless air conditioning system is a type of electric heating and cooling system that can control the temperature in your Katy home without needing ductwork. The system comprises of an outdoor heat pump (the condenser) and indoor air handling units (the evaporator) that can be mounted on the wall or within the ceiling.

Ductless AC versus Traditional AC: What’s the Difference?

The main difference between a ductless AC and a traditional AC system is that while a traditional AC system connects to your home’s ductwork to distribute cool air, a ductless AC system sends cool air to a box that mounts to a wall or ceiling in a room. Each area of your house is equipped with an individual air handler, which in turn controls heating and cooling output within that space.

How Are Ductless AC Systems Installed?

Ductless AC systems can be installed much more quickly and easily than a traditional AC system. The outdoor air handler of a ductless AC system is connected to the indoor air handling unit by a component called the line set. A hole of approximately 2 to 3 inches in diameter is drilled into the exterior wall of your house so that the outdoor unit can be connected to the air handler.

After the hole has been drilled, the outdoor unit will be mounted to your house and then the air handler will be mounted inside your home, near the ceiling. Lastly, a conduit that contains the refrigerant line, a power cable, and a condensate drain will connect your indoor and outdoor units

How Do Ductless AC Systems Work?

In summer, the air handler takes the warm air in your home and passes it over evaporator coils that are filled with refrigerant. The refrigerant then absorbs heat from air and directs this to the outdoor unit and out of your house.

In winter, the opposite happens. The outdoor unit absorbs heat from the Katy air and then passes this air refrigerant line to your air handler. This will blow the warm air into your home.  Heat transfer is what makes a ductless air conditioning system work. In summer, hot air is transferred out of your house while in winter, it is transferred into your home.

How Are Ductless AC Systems Controlled?

Ductless Ac systems have a built-in control panel on the air handler to adjust settings and temperatures. Most models even include a remote control with each air handler, allowing you to adjust the unit’s settings remotely. Unlike traditional AC systems, ductless AC systems do not make use of traditional thermostats.

Are Ductless AC Systems More Efficient than Traditional AC Systems?

With traditional air conditioning systems, about 30% of energy is lost in the cooling process. This is because traditional AC systems make use of ducts.  By eliminating ducts, ductless AC systems can save you up to 30% on your cooling costs instantly! Furthermore, ductless Ac systems also make use of high-efficiency components to further conserve energy when cooling your home.

What Is the Lifespan of a Ductless AC System?

Just like a traditional AC system, the service life of a ductless AC system varies based on factors such as usage and maintenance. With good maintenance, you can expect your ductless AC system to last up to 20 years.

What Is Zoned Heating/Cooling?

A crucial difference between traditional and ductless Air conditioning systems is that ductless systems are capable of something known as ‘zoned heating’. This basically means that you will heat or cool your room one at a time instead of controlling the temperature of your entire house.

With a ductless system, you will need to install an air handler in every room that you’ll heat or cool. The rooms where you decide to install your air handlers will be your zones. Heating or cooling your house in zones can be advantageous in terms of comfort and energy costs.

If there are certain areas of your house where you don’t spend much time, you don’t need to install an air handler in those rooms. This way, you won’t be wasting money cooling an empty area as you would with a traditional air conditioning system.

Moreover, this allows everyone in the house to enjoy their preferred temperature since there is a different handler in each room.

What Are the Advantages of a Ductless AC System?

  • They are ideal for older homes without ductwork. Installing ductwork is inconvenient and messy.
  • They generally cost less than traditional Ac systems.
  • They are more secure and convenient than window ACs or portable ACs.
  • If noise bothers you, you will be happy to know that ductless ACs are far less noisy than traditional AC systems.
  • They are far more energy efficient than traditional systems.
  • If your home has areas that are more difficult to heat or cool, a ductless system is a less expensive way to get a zoning system.
  • They are less destructive to install in your house. All you need to do is to drill a tiny hole in the wall.

What Kind of Maintenance Do Ductless AC Systems Need?

Ductless AC systems need the same sort of maintenance as a traditional AC system. Ductless systems have a filter that should be replaced when it gets dirty. How often they need replacement depends on how often you use your AC. Usually, once or twice a season should be okay.
