In this article, we'll show you how to clean and maintain your central air conditioner to keep it running efficiently. We won't demonstrate the maintenance steps for a window-mounted model here. Most central air conditioners have two basic parts: an outdoor unit (compressor/condenser) that sits next to your home and an indoor unit (evaporator) that's located in a central duct near your furnace (Fig. A). If you have a heat pump instead of a furnace, the indoor unit will be in the air handler. Use the same maintenance steps we show here. If your furnace looks different from the one in Fig. A, or you have a heat pump, use the owner's manual to find your way around it. The basic parts will be the same. The most important maintenance steps are fairly simple, but if this is the first time you've cleaned the unit, allow about a half day to carefully work through the steps. If you're not up to the task, call a pro (look under “Air Conditioning Contractors” in your Yellow Pages). Cleaning and servicing a central air conditioner costs $100 to $250.

Fig. A shows a typical central air conditioning/furnace setup. Two copper tubes connect the outdoor compressor and its condenser coil (a “coil” is a combination of fins and tubes) to the indoor evaporator coil that's located in the plenum (Fig. A) above the furnace blower. best value dyson vacuum cleanerOne tube is covered with foam insulation. best leather cleaner detailingIf you have a heat pump, both tubes will be insulated.best robot vacuum cleaner 2013 australia Outside, your main job is to clean the condenser coil (Photos 2 - 4). air duct cleaning consumer reports

The fan inside the condenser coil sucks air through the fins, and as a result, pulls dirt and debris with it. Dust, leaves, dead grass and anything else that collects on the fins will block airflow and reduce the unit's efficiency. best handheld vacuum cleaner good housekeepingGrass clippings thrown by the lawn mower and “cotton” from cottonwood trees and dandelions are particularly bad offenders. air duct cleaning organizationYou might have to clear the fins weekly or even daily during the spring “cotton” season! Always begin by shutting off the electrical power (Photo 1). Then proceed with the cleaning (Photos 2 - 4). If the fan motor (Photo 3) has lubrication ports, apply five drops of special oil for electric motors (not penetrating or all-purpose oil). You can find oil for electric motors at hardware stores.

Many fan motors are maintenance-free—they don't have oil ports (ours doesn't) and can't be lubricated. Check your owner's manual if unsure. The compressor and its motor sit inside the coil (Fig. A). They're usually sealed and won't need maintenance. However, if you have an older compressor that's belt-driven by a separate motor, lubricate the motor through its oil ports. In every case, keep an eye out for dark drip marks on the bottom of the compressor case or pad (Photo 5). This indicates an oil leak; the compressor or tubes might be leaking coolant (refrigerant) as well. If you find a leak, call in a pro to check the problem. Don't tighten joints to try to stop leaks yourself! Over-tightening can make the problem worse. And only a pro with proper equipment can recharge the system to the proper level of coolant.Air Conditioning Coil Cleaning Are you looking for superior coil cleaning services? Look no further as you have come to the best professionals for the job. Miami Cooling is your trusted partner to ensure your ac coils are cleaned in the best way possible for optimum performance.

Why do I need AC coil cleaning services you may ask? Over time the AC condition usually picks up dirt which might make it less efficient. A dirty coil normally restricts the airflow from the compressor which weakens it. This means that the hot hair will have a hard time escaping. In essence, dirty coils usually cause reduced airflow which makes it hard for the air condition system to remove humidity and heat from the house. Why Choose Us For Your Miami Coil Cleaning?
