If you are planning to hire an HVAC professional to install your air conditioner, there are a few things you can do to prepare:
Choose the right size air conditioner for your home. An oversized air conditioner will not cool your home efficiently, and an undersized air conditioner will not be able to keep up with the cooling demand.
Select the right location for the air conditioner. The outdoor unit should be located in a well-ventilated area that is protected from direct sunlight and rain.
Make sure you have the necessary permits and inspections. In some areas, you may need to obtain a permit before installing an air conditioner. You may also need to have the installation inspected by a qualified professional.
