Maintenance Tips to Take When Your Split Air Conditioner Is Not Cooling

It’s a really not day, and your split air conditioner is not cooling? Perhaps this uncomfortable situation can be prevented with a little forethought and old- fashioned elbow grease.

Routine, correct and preventative maintenance is key to keeping commercial or home air conditioning unit running at peak efficiency for a good lifespan and to ward off unexpected break downs. Here is what needs to be attended to on a regular schedule.

The Filter–Install a new filter monthly or bimonthly according to how much the unit is operated. A regular change out keeps indoor air clean and also reduces the cost of possible future repairs and professional maintenance. Check the owner’s manual for a recommendation from the manufacturer.

The Compressor–This part takes the gasses in the A/C unit and squeezes, or compresses, them from a low pressure to the higher temperature and pressure needed to cool the room air. Also, the compressor takes gas from the evaporator. This keeps the boiling point as low as possible. A good regular cleaning will help the compressor deliver cool air, and oiling the compressor, using the manufacturer’s recommended method and lubricant, will extend the life of the entire unit.

The Evaporator Coil--This part basically changes hot air coming into the air conditioner to cold air. Replace the coil to boost how well air circulates in the indoor space.

Air Ducts–Get them professionally cleaned every 3 to 5 years to greatly reduce allergens, dust and mold in the heating and cooling system. Furnaces and air conditioners will work better and more cheaply with clean duct work, too.

Refrigerant— This chemical can leak out of the unit; so make sure a HVAC technician checks it before the cooling season begins. The room air will not cool in the absence of refrigerant. In addition, ice may build up in the A/C unit. When this happens, cold air does not circulate in the targeted space. Generally, build up of ice means the unit is low on refrigerant. Consult a professional HVAC technician to change out this important chemical or to recharge the system.

Both window air conditioner and split AC units use a similar amount of electricity with the split air conditioner costing perhaps a bit more due to its extra motor. The split unit is more expensive at the outset, too, but has the great advantage of having a silence feature. In either case, the owner can defray the cost of operating A/C with regular maintenance.
