Just so we are on the same page, this is about how to clean ac evaporator coils inside house. The blower motor forces air upward (recall my air handler is an “updraft” or “upflow” type) through the furnace and air conditioner evaporator coils. The Heat and Cool functions of the thermostat ensure that either the furnace or the air conditioner operate, but never both at the same time. The supply air plenum box sits on evaporator coil sheet metal cabinet. The large trunk flex ducts connect to rigid duct board distribution trunk ducts that lay on the attic joists. Several smaller flexible duct branch lines are taken off the rigid trunk duct to supply air to vents throughout the house.
Cleaning AC coils: A simple step-by-step guide
When it's time to clean the AC condenser coils in your outdoor HVAC unit, hosing them down with water is an ideal cleaning method. If you've already switched off the electrical current to the HVAC system, it's safe to spray water from a garden hose onto the condenser coils. However, Provincial Heating & Cooling Inc. warns that you should affix plastic wrap securely around the motor and electrical wires to avoid water damage. Although moderate pressure from a garden hose is recommended, the intense water pressure from a power washer may damage the condenser coils and fins.
Locate the A/C Condenser Unit
Additionally, a furnace typically lasts about 15 to 20 years, while a heat pump lasts about 10 to 15 years. The two main types of heat pumps commonly used for residential homes are air-source and geothermal heat pumps.

The refrigerant fluid becomes a hot vapor; the outside air absorbs the heat, lowers the temperature, and changes the fluid from gas to liquid. The liquid travels back to the evaporator, which is then blown through your air ducts as nice cool air. Once the coils are clean and soap-free, let the unit air dry for a bit. Then, replace the fan, reattach the side cover, screw everything in place, and turn the power back on to the AC unit. Using a screwdriver or a cordless drill, remove the fan from the condenser unit.
I like the Nu-Calgon Evap Foam because the manufacturer’s page (previous link) includes directions and literature. I used a similar Nu-Calgon coil cleaner in the Heavy Duty AC Evaporator Coil Cleaning project. The evaporator coils are a vital component of your air conditioning system, responsible for absorbing heat from the indoor air.

How Long Before I Can Turn on my AC After Coil Cleaning?
The process starts when your AC unit pulls in warm air from your home through a return duct. The air then passes over the evaporator coils, which are filled with a refrigerant that absorbs heat. The now-cool air is then blown back into your home through the supply ducts. How to clean AC evaporator coils with no-rinse spray foam cleaner for routine seasonal maintenance. If you’re not comfortable cleaning the AC evaporator coils yourself at least you’ll what’s needed when calling a Heating, Ventilation and Air Conditioning (HVAC) professional.
Keep it clean and you’ll get a nice, tight seal, keeping the cool air where it belongs, in the fridge. You can eliminate more than 70 percent of refrigerator repair and service calls with this simple cleaning step.Do it twice a year or more often if you have shedding pets. After investing in a heat pump system, regular maintenance is necessary to ensure that it lasts as long as possible and operates efficiently.
The greenish/whitish discoloration on the copper refrigerant lines is from dissolved copper deposits that have dried. The plastic drain pan looks in good condition with no cracking or leaks. I should expect to replace the coil and/or air handler in a season or two as it approaches the end of its expected life. Air conditioning systems play an important role in keeping your home cool in the hot summer months. The first thing you need to do when cleaning your evaporator coils is to gather the proper tools for the job.
This will give you better access to the coils, and make cleaning them much easier. As AC coils are typically made from copper or aluminum, they can be cleaned with water. Rinse the coils on any outdoor central AC unit by spraying with water from your garden hose on a low setting. Meanwhile, there are number of design and manufacturing techniques available that either reduce or prevent formicary corrosion. For example, coils made with aluminum, tin plate, or polymer sealed copper are more effective against formulary corrosion than copper.
Furthermore, this metal casing carrying the unit’s evaporator coils is usually hidden in a closet, loft, or other out-of-the-way location.
