Normally, when the coil absorbs heat and warms up, the refrigerant molecules shrink. However, because there is no heat to absorb, the refrigerant in the coil will not warm up. The coil will continue to cool (and expand) with each AC cycle, until freezing. If water is present in the system, then the frozen droplets will block the airflow through the coil, preventing further cooling.
The best way to avoid a frozen air conditioner is by keeping an eye on your bills- if you notice that it's getting colder outside but your bill isn't dropping, call us at (908) 643-2220. We can check on you while you're out and about so you don't have to worry about missing any bad stuff.
The next time you see ice building up on your AC unit during the winter, this means that moisture is making its way into your system. This could be due to leaky pipes or insufficient drainage around your AC unit. Try putting a few drops of oil on the screws that hold the unit to the house. This will help prevent corrosion and make sure it's still moving freely after being shut off for several months. During the spring cleaning season, make sure to clean the exterior unit too - this will help remove any dirt or debris that may have made its way into the opening of the unit.
When the refrigerant in your air conditioner runs low, the pressure lowers, causing the evaporator coil to become excessively chilly. As a result, when returning air meets the coil, humidity or moisture from the air beads up and immediately freezes. When this happens, the ice can break off and block the airflow channel, preventing heat transfer and further lowering the refrigerant charge. This can cause permanent damage to the system.
The first thing you should do is check the owner's manual for your air conditioner to make sure that it does not have a memory function that will keep it turned on even after the vehicle comes off of the stand. If it does, then turn it off before removing the unit for service work.
If the unit was running when you removed it, then stop it from re-starting by placing a piece of tape over the switch that controls its power. This will prevent it from turning back on when the machine is replaced back into its box. You should also check all of the cables connecting the unit to the chassis for any damage. If any are frayed, then they could be the cause of your problem. Have a professional technician examine your unit to ensure that there are no other causes for your issue. He or she may also suggest replacing any worn parts of the system such as the compressor, evaporator fan, or ductwork.
The expansion of refrigerant in the interior coils causes them to become extremely chilly. The heat is subsequently transferred between the refrigerant and the circulating air. The temperature of the air drops as the refrigerant takes heat from it. Dirt and dirt on your coils might prevent this heat exchange from working properly. Dust particles trapped in the coil when you change the filter can cause poor airflow and increased energy usage.
To keep your AC running efficiently, you need to clean the coils on a regular basis. This will help remove any debris that could be blocking the flow of cool air through the unit. Also, make sure the ventilation slats on the sides of the box are not blocked by furniture or other objects. This could cause your AC to work harder than necessary.
If you're having trouble cooling off your home in the summer, there are several things you should check. Make sure all windows and doors are opened for a free flow of air through the house. If you have central air conditioning, make sure the thermostat is set at a comfortable level. You may want to consider installing ceiling fans to bring in more air during hot days. They'll also help reduce your electricity bill.
AC repair professionals recommend cleaning your air filters at least once every three months. This will help improve the efficiency of your system and allow it to operate at its best. If your filters are clogged up, you won't be able to use all of your available air flow.
