Make sure the density unit is not blocked
The density unit is part of your droplet system that stays out and absorbs air. If this is blocked by weeds, dead leaves or outdoor furniture that you have placed against it, your air conditioning may not work in the same way. what I can do. Make cleaning the area around the unit part of your regular maintenance. It is also a good idea to do this before the air conditioning service, to avoid being charged by the engineer for time spent cleaning, and also to avoid misdiagnosis of why your unit is not working properly.
Check the air flow inside and outside the unit
Once you have removed any obstacles to the density unit, check that the air flow is strong and constant in both units. If the air intake is wrong this could indicate that your air conditioning system has a blocked coil or a faulty fan. In most cases it will be necessary to call an air con engineer to investigate the problem and provide a solution.
Switch between heating and cooling modes
It is a good idea to have a DIY air conditioning service if you have been using your air con system for some time. One really simple thing you can do is try to switch between cooling and heating methods. If your air condition is stuck in one place, it usually indicates a problem with the receding valve. If this happens you should call a qualified engineer.
Fix any rust or rust
Check with your air con system, especially the outdoor unit, for any signs of rust or rust. If the damage is minor, you can usually repair it by painting over it with a waterproof metal paint. If rust or rust is severe you should call a local care professional. Ask your engineer to check for oxidation symptoms while completing your air conditioning service.
