When you switch on your air conditioning on the first hot day of the year, it can be frustrating to find out that your unit is struggling to cool the room, or worse, not functioning all. While it's recommended you get a professional engineer to complete an air conditioning service as part of your annual property maintenance, there are also a few simple examinations that you can do in between to maintain your AC working smoothly.
Keep Your AC Unit Well-Maintained
Most air conditioning faults are caused by lack of cleanliness, but just dusting the vents regularly will make a huge difference to the life of your unit. Another simple thing you may do to improve the hygiene of your air con system is to get rid of the filters, spray them down with antibacterial spray and wash with warm water. The cleaner you keep your unit, the less often you'll need to have an AC service.
Replace or Clean The Filter
The reason your air conditioning system has a filter is both to protect the mechanics inside, as well as keeping the air clean inside your home or workplace. If this filter isn't maintained clean you're making your air con system work harder and less efficiently, meaning your energy expense will be higher and your annual AC service might not be enough to keep your unit in good health. Some air con filters need to be cleaned rather than replaced and vice versa. An electrostatic filter is cleaned, while a disposable fiberglass or paper filter need to be replaced fairly regularly; anywhere between once a month and twice a year, depending upon the air quality in your area. Check it regularly to determine how often you need to be changing yours. A filter which needs changing will look blocked with dust.
Make sure the Condensing Unit is Not Blocked
The condensing unit is the part of your air con system that sits outside and pulls the air in. In case this becomes clogged by weeds, dead leaves or even outdoor furniture you've stored against it, your AC may not function as well as it could do. Make cleaning the area around the unit part of your regular property maintenance. It's also good to do this before an air conditioning Coon Rapids MN service, to prevent being billed by the engineer for time invested cleaning, and also to avoid misdiagnosis of why your unit isn't functioning properly.
Examine Airflow On Inside and Outside Unit
When you've eliminated any obstructions from the condensing unit, check that the airflow is powerful and consistent on both units. If the airflow is poor this can indicate that your air conditioning system has a blocked coil or a failing fan. In most cases it may be necessary to call a professional air con engineer to investigate the issue and provide a solution.
Switch Between Heating and Cooling Modes
It's a good idea to do a do-it-yourself AC service if it has been a while since you'd used your air conditioning system. One really easy thing you can do is to try switching between the cooling and heating modes. If your air conditioning is stuck on one setting, it normally indicates that there is a problem with the reversing valve. If this occurs you need to call in a professional engineer.
Repair Any Rust or Corrosion
Check over your air con system, especially the outdoor unit, for any signs of rust or corrosion. If the damage is minimal, you can usually repair it by painting over it with waterproof steel paint. If the rust or corrosion is more severe you must contact a property maintenance professional. Ask your contractor to inspect for signs of oxidation while completing your air conditioning Andover MN service.
