It may be tempting to research how much it would cost to just watch how-to videos and install your own ductless system. But it is important to keep in mind that this will almost always void the warranty on your machine, and could cause other problems. One of the main issues is being able to problem seal off the air tubes. If there is not an air-tight seal, then nothing will run properly at all. This often requires products that are very specific to the make, model, and install of the unit you choose. Additionally, there are much more sensitive electronic components inside ductless systems that can become awry if subjected to excessive rustling. For example, the component that takes the temperature could be damaged, thus the model will never read the right temperature, making operation quite the chore to figure out what your model’s internal thermostat is doing. Additionally, according to EPA guidelines, you must be certified in order to handle certain kind of refrigerant. This makes it difficult to obtain the necessary supplies, and even harder to carry out the procedures. It is quite worth it to pay for a professional, as they save on the materials by having the HVAC provider provide the materials to them in bulk quantities. The good news is that once you decide to have a ductless system installed, each unit only takes about three to seven hours on average. This makes it easy to do a whole house within a week. Duct systems are much more invasive and often require the whole house evacuated for installation.
