Call a service tech to look at your central. If it’s not keeping up then it might be cheaper to fix the issues with it over buying a window unit and paying the electricity to run it.
Central Units are typically much more powerful and therefore need to run less, and if it’s something simple like it need to have the condenser cleaned out or the refrigerant recharged the cost to just get it done is much less than the cost of window units plus electricity plus your time to install and remove them
Yeah for new installs but service for the existing unit might be like $200 for a cleaning and it’s certainly going to be cheaper to run in the long run
Window units are built to fail, are mold prone, use an excessive amount of electricity comparatively (even the newer inverter ones) and a higher risk of injuring a person or damaging the building. Also their smart features often entice people to install apps that track you to sell to advertisers. So not only are you buying an inferior product but they’re also capitalizing of spying on you.
