I appreciate any help in diagnosing my issue. Here're the details. [B]The Unit[/B] Goodman Model GSZ130421AE 3.5 Ton [B]Yesterday's Problem[/B] Yesterday we came home to 88 degree F temperature inside our home (Florida). The heat pump inside was running and blowing warmish air out of the vents. The thermostat was showing the unit set to cooling mode and showed a temp of 88 degrees F. The condenser fan was NOT running and there was no sound coming from the condenser/compressor system. I switched off all breakers and then switched them back on and went back outside. There was a humming noise coming from the outside unit, but the fan was still not running. After about 60 seconds of the breaker being switched back on the noise stopped completely and the fan never started after several minutes. I replaced the capacitor and the fan began working as normally. The fan did make a loud noise when running (see The Current Situation below) but everything else seemed to be working correctly and the house cooled down to the desired temp (72) within about an hour. [B]The Current Situation[/B] As noted above, the condenser fan outside makes a screeching sound while it runs. The sound starts as soon as the fan starts up and stays on as long as the fan runs. The fan seems to start up and shut off when it should, and the system seems to be cooling the house as it should, maintaining the temperature set by the thermostat (72).

I have an A/C company that we have used for a while now coming out next Thursday (September 6th) for an annual maintenance (cleaning coils, inspecting system, etc). My first, very uneducated guess is that the issue is with the condenser fan motor. What I'm trying to figure out is: [LIST] [*]What is the problem causing this noise? [*]Is it DIY? [*]If not, is it safe to wait until next Thursday (10 days from today) to have addressed, or should I call for emergency service (which is likely going to double the costs) [/LIST]I'm new here, and I read the posting rules, so hopefully I've posted correctly, but please let me know if any different information is needed. Again, thanks so much in advance for the time you take to review my issue and help me figure it out.

Hi, I own a 11 years old HiSeer (I think that's cheap Chinese company) A/C unit. Model: SHCR-24K-31B Cooling Capacity: 24 000BTU I have been trying to take care of it by changing the filter on a semi regular basis (4-6 months, whenever it would seem clogged) and did a regular broom-wipe on the aluminium fins to remove the dandelion seeds when it is the season. Today I received a notice from my thermostat that it had been trying to cool for a few hours but the temperature has been going up. The filter was mildly clogged and I changed it, and I see that the big fan on the unit is turning, but clearly there is no cold air coming through. In the past, I've seen my neighbor had to change the capacitor, but could it be that if the fan is turning? The proper way to check the capacitor is to check if there is a short between each "leg", correct? I know that another issue could be related to the pressure of the gas inside the circuit, and I read the sticky stating that if this is the case I need to ask for a professional. 1- Is there anything else I should check before I make a service call? 2- With the above information, apart from adding gas, what else could be the issue that the technician would diagnose? 3- When is it better to change the whole unit instead of adding more gas/making a call? Thanks
