Just because the condenser is outside is no reason to neglect. I see this all the time with our neighbors, & sincerely I’m amazed their central AC units are even still finally working. I guess it could be because no a single genuinely knows how their heating & cooling unit genuinely functions. Maybe if they did, they would take better care of it. The condenser is a vital section of the central A/C. The multiple vents & slots in the metal which incase the entire unit, also known as the cottage, are designed that way for a reason. The condenser is where hot gases get cooled with outside air, before traveling back into your home as cool & refreshing air. Think of your condenser care about the cooling vent on your PC–if you block it even for just a few minutes, it can begin to overheat. So what you suppose an incredibly complex & intricate plan care about your central A/C unit will do if it becomes too overheated all because someone couldn’t be bothered to mow the grass & pull back the weeds? I always cared for the condenser which can spell certain death for your entire central cooling system if you’re not careful. I suppose the high cost of installing a current condenser or repairing components to our central AC is worth the sweat & effort of a little yard work. My insuring your AC condenser has maximum flow, you are also making your AC plan is performing at its easily best, however every month when you replace the A/C filter, make sure to check on the condenser, & you’ll have an awesome AC unit for years to come.
