This is easy however if you are unsure, consider asking for help from an electrician. Alternatively, ask the Heating, Ventilation and A/C professional to handle the entire process, however once you handle the wiring stage, check & test your complete replacement, then homeowners need to familiarize themselves with some of these processes to avoid incurring unnecessary Heating, Ventilation and A/C repair costs for things they can handle.
