Need to charge unit

Hello my name is Heath it will be my pleasure to assist you. The first thing to check is the filter in the furnace or air handler. Also check the inside coil to be sure its not frozen up. Does the air coming out feel cold? It sounds like the unit could be low on charge which means it has a leak and should be leak checked repaired and properly charged. You would need refrigeration gauges to put on the system in order to properly check the refrigerant charge in the system. One other thing could be a dirty condenser coil. Turn the power off to the unit and use a garden hose with a strong nozzle and spray water through the whole coil to try and blow any dirt or debris through the condenser coil in the outside unit.

Hello, the coil will freeze either due to low airflow or a low refrigerant charge. Many times a dirty air filter or dirty evaporator coil will cause ice to form and cleaning both will fix the problem, however if the unit appears clean then a low refrigerant charge is the problem and the unit will need to be recharged.

The temperature outside and pressure chart are needed to accurately determine the proper charge. (temperature pressure charts to calculate heat gain) However the low side of the unit should read around 70 and the high around 210. This is a really broad generalization and I do not recommend you charge your unit just on this info. It will get you close if you are using R-22 and the unit is properly cleaned. A dirty evaporator coil will cause a severe low pressure reading on the low pressure side.

It all depends which coil you are speaking of, Evaporator or condenser if you are lucky to find a used match which is highly unlikely. newer units have has their seer rating changed substansually causing both coils to be replced at the same time and by the time that is done a new lineset is required to elliminate cross contamination so its not good news depending on required tonage 3000 to 5000 dollars installed sorry wish it was better news

I would highly recommend that you get a friend or hire a pro, to deal with this. You dont just add freon, is it -R22 or the new 410A type? You always charge a system from the outdoor unit! If this is a new outdoor condensor, it will be pre charged for the unit, indoor coil and roughly 15 to 25 foot of line set. But after the brazing is done,,, NEVER SOLDERING! You need to use a Vac-Pump and pull the indoor coil and lineset down to 500 microns, before you open the king valves.
If this outdoor unit was used, then does i match the indoor coil? In sizing and type of refrigerant? Need to reclaim the existig refrigerant, pull a deep vacummn on the whole system and then weigh the charge in, according to the tag on the outdoor unit. You should have a CFC license t work with any type of refrigerant, if someone turned you in, it starts with a $ 10,000.00 fine for a start, You need allof the right type of tools and knowlege, save time and money,,,, get a CFC licensed tech,he will know all of this.
Sincerely,
Paul
