You don't really need a special machanism to check for air leaks in your house. The usual suspects are doors and windows. To check you can hold a candle near the door or window and if the flame flickers then you have a draft. You can also use incense to find leaks because the smoke will be pulled to the leak if the leak is from the house out, or pushed away from the leak if its air coming in from outside. All you have to do is follow the smoke.

WHAT IS THE BEST WAY TO DETECT THE REFRIGERANT LEAK BY THE SOAPY WATER OR LEAK DETECTOR?


a leak detector is by far the best method as the gas will show up under the light where it will not run with out gas so soapy water has a limited ability to show a leak

Best bet get a can of leak detector from the auto parts store. It will be a can of 134a with leak detector in it. you will run the AC as normal and the dye will show you where it is leaking at.

What are fiber-optic leak detectors?


These are leak detectors that fiber-optic cables that run the full length of the pipes that you want to check for leaks. They work by measuring the changes in temperature of the cable when it comes into contact with the substance that is in the pipe. This gives you a really acurate reading of where the leaks are.

Ac outside..copper tubes freeze up,not cooling well inside


No! Check the condenser isn't clogged up first. Then check all internal filters and fans. Check for leaks with an electronic detector and repair any leaks before vacuuming the system and maybe then replacing the refrigerant.

Every thing is working, but dont cool the house down. i check the pressure and can not get a reading


Seems you have a leak & lost your Freon Coolant! Have someone add some Freon with leak detector & look for a oiley color, usually purple die or red die! If their is any Freion in your system you should show some pressure readings!

Not cooling 110 sq ft room


The smallest retail AC unit will cool down a 110 sqft room if...
1. It is installed in a way as to dump heat outside... 2. There is actually cool air coming out of the AC (it is working)... 3. The windows and doors are tightly closed... 4. There are no major drafty leak issues (i.e. hole in a wall)... 5. You're not adding substantial heat energy into the room (such as having 10 sweaty fat men eating food while watching Super Bowl on a 56" LCD TV)... 6. The room has at least minimum insulation (the walls are not just plywood)... Seriously, if HEAT is leaving the room by way of the AC, the room temperature HAS to decrease, unless HEAT is being added back into the room in some way. This is basically the 1st law of thermodynamics.

The detector has gone off two times within the last week. The detector reads "GAS" when it goes off. THe number the first time was 199 and yesterday is was 235. The first time I got out of the...


Propane is heavier than air so if the detector is mounted ABOVE the appliances that use it (or any tubing that brings the propane into the house) it (the propane) will NOT be detected, even if there is a leak. That said, the PRODUCTS OF COMBUSTION of a propane appliance will still contain carbon monoxide (CO) which is lighter than air and will be detected by a properly installed detector. If you continue to get alarms and readings that differ from each other, along with no error codes on the display, it sounds like the detector is really detecting something. If the fire department cannot identify a source, try calling the Kidde "Hotline" at 1-800-880-6788 and ask if they can recommend another agency in your area to check your premises. I don't think these units detect Radon but am not sure. If your dwelling is of relatively new construction, the problem can be complicated by the fact that there is less outside air infiltration to disperse any build-up of gas/radon/CO/etc. than is typical in older construction. *Disclaimer: I am not a lawyer, despite the handle.

Unit not blowing cold air


you have a slow leak in your refrigerant and need to find the leak. you will have to get an AC repairman to come to your house and check it for leaks and fix the problem.

Short cycling air conditioner


depending onthe age of the unit it would be wise to have someone use a refrigerant leak detector to find the source of the problem. if it is over 15 years old i would probalby think about replacing the unit with a new 410A refrigerant unit due to the R-22 refrigerant getting phased out of production(the price is really going up) it sounds like the company you have might not know what they are doing i would look in the phone book and call another company and ask about doing a whole sytem leak search it might cost about $500 bucks to find the actual leak and repair it (have the guy physically show you where it is with his meter) but its a lot cheaper than adding refrigerant every year

Leak in air conditioner on 2000 town country


Dyes you can't usually see unless you take it apart. The easiest way i can think of is to use a leak detector that finds the leak by sniffing. Start the vehicle with a/c on place tip in the interior vent, if there is a leak it will detect it. Can be used to find any leak in the a/c system.
