You have finally done it. After all that research you have finally picked the right cooling system for your home. Picking a cooling system is difficult. There are so many questions you need to answer. Do I have ductwork established in my home? Do I want to install ductwork? Am I cooling a single room or many rooms? Do I want to be able to heat my house as well? All these questions need to be answered in order to pick the right system. Next is picking the right brand and size. Get exactly the right system for your home. Is bigger necessarily better? Also you need to pick your location for your new air conditioner. The size depends on the location. After all these decisions it is time to install the system. Installing your cooling system is exciting. You are finally going to be cool in the summer. You will not have to worry about sweating and being overheated. Everyone has a moment where they contemplate having a friend install their system. Our new cooling unit can be expensive. After spending the money on a system it is natural to not want to spend a lot of money to install it. We also all have that handy friend. This friend is very mechanically inclined and could probably install your system. Your friend should not install your system however. Improperly installed cooling equipment is prone to frequent break downs and is not as energy efficient. Also air conditioners have refrigerant. You need the proper amount of refrigerant in your cooling system on that initial installation. Hire a HVAC technician you trust.
