You know how when you change the filter in your air conditioner, it has a little arrow on the edge showing which way the air is supposed to flow through it? What do you think happens if you put it in with the arrow in the wrong direction? And then let it get too dirty? That's what happened with the filter below. Notice that it's dirty. Notice also that it seems to be a bit lighter in color in the center. Looking at it from the side (above), you can see that the filter material is blown out. The blower in the air conditioner was trying really hard to pull air through the filter but the static pressure across it was high because of the dirt. Looking at the other side of the filter, you can see the wire mesh is now separated from the filter fabric. Of course, now it's clear why that wire mesh is there in the first place. It holds the filter fabric in place to keep it from getting sucked into the blower.

What happened here is that the air conditioner pulled so hard on that filter that it sucked big chunks of the dirt and fabric off of the filter. Then it deposited them on the evaporator coil. 2 ton ac unit price installedA while back I wrote about a dirty evaporator coil, and that one had a large accumulation of small stuff.thru the wall air conditioners with heat In either case, the result is that air can't move through the coil very well. thru-the-wall air conditioner best buyThe coil gets colder and colder because it's not picking up heat from the house. There's some water there because of the air that does get there. Then the coil turns into a block of ice. The photo above is not from the house where I took those filter photos because I didn't open up the unit.

It was definitely frozen up, though, because the ice was even coming out of the housing. The photo here does show what happens, and you can see that when a coil freezes up, no air will move through it. This picture is from one of my favorite Facebook pages, HVAC hacks and other screwups.) The Sludge That Kills — Post Mortem of an Air ConditionerDo you have any questions about our services? Read our privcy policy Air Conditioner is Freezing Freezing of your AC coil occurs when the refrigerant inside a central air conditioning unit falls below 32 degrees Fahrenheit, Canadians would measure it as 0 degrees Celcius. What is actually happening is the humidity that surrounds the coils is freezing up. Running the unit with the coils iced over can strain the compressor and cause major damage to the unit. Usually Coils freezing up means low air flow or a slight undercharge of refrigerant. Low air flow is the most common. It could be a result of a dirty filter, dirty ductwork, damaged evaporator coil, restrictions in the ductwork or even a mismatched system where the outside unit is to large for the evaporator coil inside the furnace.

Thawing the AC Coil Don’t be tempted to help the thawing process by removing chunks of ice by hand, resist that temptation. The coils and cooling fins in the evaporator portion of the central air conditioner can be easily damaged. Ice clings tightly to these components, and forcefully removing it can bend fins or rupture the coolant lines. It is a good idea to turn off the power to the the air conditioner and the fan on the furance. You do not want water to drip down into the furnace and possibly damage electrical component boards inside the furane . Thawing may still take several hours. One of the first things to check is the filter. Check all the rooms in the house and make sure the supply registers are open. If outside air temperatures fall below 60 degrees Fahrenheit, 16 degrees Celsius most central air conditioners do not work properly. Consider shutting the system off when temperatures fall below 60 degrees. This is not a Do It Your Self Job. Call your local qualified service technician to check and refill refrigerant.

Air conditioning repair people understand how to work with the pressurized refrigerant system and will be able to quickly determine which type of refrigerant your system needs. Frequently when Power Vac is cleaning ductwork we do find blockages in the evaporator coils inside the furnace. Blocked coils are a result of the fins of the evaporator coil getting plugged up . The close spacing of the aluminum fins on an evaporator coil makes it easy for dirt, dust and other debris to stick. Lodged debris causes blockages, affecting the overall performance and efficiency of your air conditioning. Air flow across the coil becomes blocked, degrading heat transfer. Blockages come in the form of build-up from skin cells, fabric fibers, pet hair, grass clippings, tobacco smoke, pollen, mud, rust and bacteria. Is Your Heat Pump Freezing Up? There are several factors that can lead to your heat pump freezing up during the summer cooling season or the winter heating season. You can fix some of the simple problems that lead to freezing yourself, while it will be necessary to call an HVAC expert for more technical repairs.

It’s normal for heat pump coils to have a light coating of frost on them, but a thick ice buildup is a sign of operating problems that will prevent your system from heating and cooling properly and can lead to your heat pump freezing up. A heat pump has automatic controls that should send the unit into defrost mode to prevent ice buildup during normal operation. An HVAC technician can check to be sure those controls are operating correctly. Ice can build up on the coils if the airflow across them is restricted. This could be caused by clogged filters, blocked ducts or by blockage of the outdoor unit by leaves, grass or snow. Be sure your supply and return ducts are unobstructed by furniture, carpeting or closed doors; clean or replace the air filter regularly and keep your outdoor unit free of debris. Conditions unrelated to the mechanical integrity of your system can lead to a heat pump freezing up. Freezing rain or leaking gutters can let ice accumulate on your outdoor unit and block airflow.
