HVAC work needed
 

Hello all,

Is anyone in the AC trade?

Need servicing of current system or estimate to replace.

give me a call after 5 if you want. 813-393-6302

thanks man, i found out what the issue was. :banghead:

edit: scratch that, if it's ok i will call you tomorrow.


i'll post the problem i'm having; the coil in my air handler is icing over. the filter is new not sure what the problem is... anyone got a clue?

low freon

ice forming on the air handler coil could be caused be a number of things. air blowing across the coil at a reduced rate, enough so that an optimal heat exchange rate is not met (not correct volume of air blowing across coil leads to the coil operating at a temperature much lower then design intent) causing the coils to super cool and freeze the condensation that constantly forms on the coils. this could be caused by a clogged filter, dirty coils, failing blower motor, damage to the fan, or low freon. the air handler at your house operates similiar to the one in your vehicle. if youve ever been low on freon in your car you will hear your compressor cycle on and off. this is because the compressor will not engage unless it has sufficient freon. when the correct amount of freon is on the suction side of the compresor, the compressor will engage and continue as long as a sufficient freon is fed to it. as soon as the compressor engages, in a vehicle low in freon, the freon pressure will drop resulting in the compressor kicking off again. your residential unit does the same thing. so it will super cool the coils in spurts, causing icing of the coil. check to ensure that your compressor (outdoor unit) is engaging and consitant to start ruling out some things. but most likely you have a freon leak. tracing the leake can be difficult and time consuming, however many times the leak is as simple as the test ports for the freon lines leaking. if the unit has been serviced for this in the past the service tech would add a green dye to trace the leak. if not, just look for a dirty part in the lines. a leak will leak freon into the atmosphere, but leave behind the compressor oil. this remains on the pipe and attracts dirt and grime. if you find something like this, clean it, and check after a day. hope this helps. let me know if you have any further problems or questions.

WoW, great explanation! Thanks!

Man, if it's low on freon that means i have a leak somewhere... :banghead:
which sucks because when I moved in here '09; I had the coil replaced cause it was leaking or so the tech said.

I guess that wasn't the only leak. :ack2:

chances are the leak is in a joint, or in the coil. easy to find. the copper that runs from your air handler (inside) to the compressor (outside) is typically a single piece of spooled copper. this means that a leak somewhere burried in the house is relatively rare. check the fittings around each unit. the last house i was in, the leaks where in the test ports. these are located just outside the compressor and have caps on them. alot of times these are not properly tightened and the valve eventually slowly leaks. any service tech can come out, locate the leak, remedy and refill your system for less then $100. your best bet is to find a small, one man residential company. this way your not paying for the overhead of a big office, advertising, ect. i found a guy that i have used a few times, and did a great job. same problem your describing cost $80. come out, locate, fix and refill system. check online for local listings. the guy ive used in the past name is bob. 813-317-8628. letme know if theres anything else i can help you with.

Thanks man, you've been a big help! :thumbsup:

you got it. anything to help. let me know how you make out, what the problem was and the fix. if you dont call bob hopefully you find another great service tech. post up becuase as summer is quickly upon us, im sure your not the only one who will have problems with their ac.

tiny leak at the unit outside, 3lbs of freon added! :thumbsup:
