Frequently Asked Questions:
Air Conditioning Unit?
The Air Conditioning In My House Is Not Working I Went To Check The Unit Outside And There Was Ice On The Pipes That Connected My Air Conditioning Unit To My House On A 90 Degree Day Should I Call Somebody To Fix It Or Is This A Problem I Can Fix
I just hate it when armchair a/c techs automatically rattle off: "its low on freon!" Ugh....
OK,.. at the thermostat stop the cooling and run fan on only for a couple hours. The evaporator is a big block of ice if you can see it all the way back to the condenser.
Have you checked & changed your filter? There are 3 things that will freeze a system. Low air flow, metering device malfunction, and low refrigerant.
Note to the inexperienced: air conditioners do not use freon. They run refrigerant. Freon is (was) a trademarked name for a CFC refrigerant made by DuPont that is no longer used. There are currently over 350 refrigerants. None of them are freon.
OK, back to the issue. You may very well have a low refrigerant condition. The bad news? -if you do then it went somewhere; there's a leak. That leak must be found and fixed by an EPA certified tech. Its technically illegal for a tech to just shoot refrigerant into a system that has a proven leak. Thats the EPA 15% rule in section 608.
If you have a metering device malfunction, same thing. Thats not something you can do.
How about the cleanliness of the evaporator coil? Thats something you can certainly handle. Get the evaporator clean so the air will pass through it. Use something like a brand new dollar store toilet brush and Clorox Clean-up. Rinse well with a miscellaneous spray bottle of water & vinegar.
If the fan capsule (squirrel cage fan) is dirty and filthy that will not move alot of air. Take it out and clean it. Those small concave blades get caked with micro dust and stop moving air efficiently....
If you have not cleaned the condenser coil outside then how do you expect it to reject heat??
Look, if you have not had thing this serviced yearly, you are neglecting it.
This is why we preach and preach to have regular service & cleaning; its not just so we can find something to charge you for. Its so the system will run at peak efficiency and peak performance and be RELIABLE.
I don't understand why people think the HVAC system will maintain itself, fix itself and run forever with no help....
What you really need is a competent tech out there like right now.
Thats my 2 cents.
What Does &Quot;Change Of State&Quot; Mean? And Why Isit Important To Air-Conditioning Units?
When a refridgerant changes state;
From a higher pressure liquid to a lower pressure gas,
All heat is absorbed, and the result is coldness.
Sort of like when you spray deodorant on yourself, you can feel the coldness., refridgerant does this in a sealed systom, over and over resulting in a hot side and a cold side, changing state from liquid to gas, and back to liquid.
How Does Tonnage Of An Air Conditioning System Varies With Required Temperatures ?
I Want To Know That How The Tonnage Of An Air Conditioning System Changes With The Change In The Required Temperature ?
A good (not precise) rule of thumb is it takes 1 ton for each 1000 square feet of room space to cool a home to 75 degrees. of course, insulation of the home or business plays a big factor.
Obviously, if you are keeping a large freezer area (as a warehouse for frozen foods), the need of tonnage will be much greater.
Forgot to tell you why the need is greater at lower temperature.
The rate of heat transfer for a given substance (think wall) is determined by the heat differential between the inside and the outside. To maintain a lower temperature inside at lower temperature with the same wall, requires more cooling.
Why Is The Central Electric Air Conditioning Unit That Is In My Home Leaking Water When Its On???Help?
I Have An Electric Ac Unit, In A Door Of My Home, And I Just Noticed That I Heard Some Water Dropping And Looked In There To See That It Was Leaking A Pretty Big Amount..What Is Happening And Should I Be Worried....It Didnt Start Till It Got About 105 Outside Yesterday...Please Help!
The condensate goes to a plastic tube that should go to a place to dispose of the water. Each Spring, we put a cup of bleach in that drain hose because all kind of crud builds up in it. Good luck. This works for this house.
Where Is The Model Number On Indoor Coils Found. Heating And Air Conditioning. Central Air?
If it's not on a data plate on the front of the service panel, then locate the section of the indoor unit to which the copper lines are running, this is the evaporator coil, and maybe there is a number on this section.
