Tips For Purchasing A Mini-Dual HVAC System For A Tiny Home

You have many options for heating and cooling your tiny home, and one of them is to install a mini-dual HVAC system. Providing both hot and cold air, these systems work well in small, well-insulated areas and take up minimal interior space. Here's more information about these machines and tips for choosing the best one for your situation.

About Mini-Dual HVAC Systems

Mini-dual HVAC systems are comprised of two parts: an exterior compressor that heats and cools incoming air and an interior wall unit that distributes the conditioned air. You can get systems that support one interior unit for one room or multiple wall units for multiple rooms. Though they require electricity to run, they are energy efficient in most environments.

Pros and Cons

One of the main benefits of mini-dual HVAC systems is they don't require you to install ducts in your home since the wall unit does all the work of circulating the treated air around the area. This, coupled with their small size, makes these devices very flexible, allowing you to zone the rooms in your tiny home exactly the way you want.

Another benefit is these systems are energy efficient. Because there are no ducts involved, a mini-dual HVAC system can reduce your energy consumption by up to 30 percent. Each wall unit has its own temperature control, which can further help you save on your energy bills.

Lastly, they operate on electricity, so you don't need to worry about hooking up to a gas line, though you will need to make sure you're generating enough electricity if you're using a solar power.

Mini-dual HVAC systems work best in areas with moderate temperatures. The system becomes less energy efficient the closer the environment gets to the more extreme ends of the thermostat because the compressor has to work harder to maintain the indoor temperature. So if you live in really hot or cold areas like Arizona or Alaska respectively, you may want to use alternative heating and cooling methods.

The wall unit uses a fan to circulate the air around the room, so you may have to deal with some noise. Although wall units are manufactured in neutral colors, they do tend to stick out.

Possibly the biggest drawback to purchasing a mini-dual HVAC system is the cost. Depending on whether or not you install the system yourself or have HVAC contractors do it for you, you can end up paying $2,500 to $6,500 for the unit. This is definitely something you need to consider when buying this device for your tiny home.

Things to Consider

The most important thing to consider when purchasing a mini-dual HVAC system is the size. If you get a system that's too small, it will struggle to heat or cool your living space. Getting a unit that's too big, though, will result in wasted money and energy. Here is a handy chart to help you estimate the size you'll need for your tiny home.

To save more energy, look for a unit with a programmable thermostat and sleep mode. These features let you vary the temperature according to when the home is being used. For example, you can set the thermostat to your preferred level when you're home and set it lower when you're away, so you're not wasting energy keeping an empty house warm. Sleep mode automatically turns the thermostat down when you go to bed and turns it back up when you awake in the morning.

Tiny homes are typically 100 to 400 square feet in size. You may be able to get away with using only one unit to heat and cool the entire space, especially if you have an open door plan. If you're tiny home has multiple floors or rooms that are closed off, you may want to consider getting a system that lets you install multiple wall units throughout your house.

Mini-dual HVAC systems can be challenging to install, so it's best to have an experienced HVAC contractor do it for you. For more information on buying this type of system for your home, contact a contractor near you.
