A line or coil freezing is a sign of restricted air flow or low on freon. Make sure the fan that circulates the cold air is working and the filter and coil at the filter are clean. A dirty coil can be cleaned with coil cleaner and a water hose. You will need to remove the unit and take it outside. (window units only) You can buy a bottle of coil cleaner at any hardware store. Follow the instructions on the bottle but basically you spray the coil until soaked wait 5 minutes and flush it clean with water from a hose. Repeat if necessary. Try not to get water and cleaner on the controls. Be careful water will be trapped in the unit you may want to tip it toword the back for 10 minutes or so and if possible let it set outside to dry. Reinstall the unit and put a clean filter on it and give it a try. If ice forms again it is low on freon and will require a repairman to fix it. Freon is a restricted item and you have to have a license to buy it. good luck..

My wall split a/c 24000 btu work about 1 hours or more after no cooling and u can see frost in the indoor coil and on the coppers on out door unit and i have low pressure 40


Low pressure and frost on your indoor coil with the copper pipe to your outdoor unit is almost guaranteed a low refrigerant charge. It can also be a bad metering device. You will need to check you high and low side pressures to be sure and make sure you let the frost thaw before checking pressures.

What size gas line for 400,000 btu water heater


Thank you for posting your question here on Fixya.com.


Is it Natural gas or LP gas?
What pressure does your gas provider supply it with? (It will usually be low pressure, ~14"WC if NG)
How far from the access point you will get gas from to the heater?

Once you have answers for these three questions use the installation guide found on pages 13-14 of this manual to determine the proper gas line size. Be sure if you use a different material pipe, like CSST, you adjust the pipe size based on manufacturer's recommendations. 1" copper and 1" CSST are NOT equivalent!

Freezing up TD-64-24 beverage cooler


Some of this TRUE don't have service valves, but you can put a tapping valve (A1) in the appendix (small piece of pipe comming out of the compresor and seal on the other end).To check the pressure you need to know what type of refrigerant is in the system .If is 134a the low side should be about 24psi and the high around 160 it could vary depends how hot is inside the place and the fridge but not much more than 200.If you working with R22 pressures be around 60 low and 250 high side.
