So, who does this? This is not typically a task you would ask a heating and air conditioning professional simply because to the cost benefit. The cost to hire a HVAC guy will run you about $95 an hour versus hiring a house cleaner for $25 an hour. We called a local house cleaning company, Naperville House Cleaning Service, to ask how they do it and this is what they said:
Step 1: Sweep the floor in the front of the refrigerator and remove anything in the way. Carefully pull out the refrigerator, using both hands. A refrigerator is on wheels so it should come out easily. After the fridge is pulled out unplug it. Try not to disturb the water lines to the ice maker. Rupturing one of those could cause a nasty water leak.
Step 2: Clean the back side of the refrigerator with soap and water. Sweep and wash the floor where the unit was standing.
Step 3: The coils are usually behind or under the refrigerator, accessible through and access panel. Once you can access the coils carefully use a vacuum to clean the coils. It’s not necessary to use soap and water.
Step 4. Replace the access panel, plug the refrigerator back into the electrical cycle, then push the refrigerator back into place.
Checking The Air Conditioner Capacitor, Air Conditioner Outdoor Fan and Air Conditioner Condenser Unit.
It’s important to share any information that we can provide when it comes to the DIY diagnostics of your central air system. A homeowner can save hundreds if not thousands of dollars in home improvements if done themselves. I found this little gem of a video on YouTube that is the first part in a series of videos that is a good example of a step-by-step process of diagnosing.
The air conditing repair technician goes over a few simple repairs that can save you hundreds of dollars if you are handy around the home.
Capacitor Repair: Not a lot to replace. Just take the wires off the old capacitor and place the wires on the new one.
Fan Motor Repair for the Condensing Unit: Most of the motors are universal in mounts and are versatile.
If the unit has been running turn it off for 2-hours and wait for the heat to dissipate.
Remove the fuse block
Turn the Thermostat on.
Put the fuse block back in (prior to testing take the fuse block out as explained).
When the unit starts running you should hear the compressor running and the outdoor fan unit. If one or the other does not run then you have an idea which part is not working. This is the diagnostic described in the video.
If neither work then most likely the capacitor is faulty.
If the condenser is running & fan not working, it will increase in noise as it reaches higher temperatures. If this is the case then you just need to replace the outdoor fan motor.
If the fan is running but you do not hear the compressor running, after the fuse block is put back in, then most likely it’s the capacitor in need of replacement. Sixty percent of the time the problem with the unit is the capacitor or fan.
If neither the outdoor fan motor or the compressor start then you will need to diagnose the power going to the capacitor. Is there power going to the capacitor?
If you have no voltage then you will need to check the disconnect box.

It’s not that easy to spot problems in most AC units. If the problem is noise, for instance, it often ranges from a steady low humming sound, a rattling noise and to a more pronounced one that could become an obvious nuisance. Most of the time, even such a seemingly simple problem as air conditioner noise could be hard to diagnose. It would require opening the actual unit and testing its various parts just to find out the culprit behind the noise. In short, it’s never really recommended to solve most AC problems yourself. With that said, one of the best AC repair tips is to let the experts handle it.
However, we are not completely excising the possibility of users being able to troubleshoot common problems that plague air conditioning units, though. We just have to stress that you would have to take the time to learn how to pinpoint the exact cause. As for the actual solution to very technical problems, it’s always best to leave it to trained technicians. What’s good is that you can use the list of common air conditioner problems as a reference below.
Troubleshooting Common Air Conditioning Problems
1.) Failure to Clean the Filters
The importance of cleaning the filters could not be stressed more. Without adequate regular maintenance of filters, dirt that has accumulated on them would take its toll on the entire functionality of the unit, leading to decreased room cooling, increased power consumption and, of course, more expenses for you.
The good thing is that this problem can be easily addressed from active cleaning and replacing of filters alone. Of the number of AC repair tips out there, this is certainly the one that is highly encouraged. It promotes optimal functionality and longevity of your AC unit, after all. Additionally, there are certain units that could do with a reusable filter while there are others that could not. You have to keep this important pointer in mind as well.
2.) Leaking Refrigerant
This is a problem that should be taken care of as soon as possible as it has been proven to be hazardous to the environment. Refrigerant leaks are issues that only expert technicians can handle. After all, simply adding more refrigerant doesn’t take care of the root problem. The charging of the refrigerant is a delicate procedure as well. With a refrigerant that is properly charged, you can always be sure that your AC would always function at its best capacity.
3.) AC Unit is Leaking Water
This issue is common in countries where there are very humid climates. As for the actual leaking problem itself, there are a number of causes behind it. If the water is dripping and is concentrated on the air handler, for instance, the leak could be coming from the plastic pipes that transport water. One other cause is a defective condensate pump. Whatever the cause of the leak is, it’s best to call your local servicing company to fix it as soon as possible.
4.) AC Unit is Noisy
Air conditioner noise is attributed to a variety of factors based on the type of noise produced. For instance, if you start noticing a squealing sound, then it’s most probably an issue with a belt-driven air handler. It could that the belt is not aligned correctly. A grinding noise, on the other hand, is a telling sign that there is a problem with your direct-drive blower. Lastly, if your unit has a furnace and is emitting a vibrating type of noise, one of the simplest AC repair tips that you can do is to make sure that the lid is properly screwed shut.
5.) Thermostat Sensor Issues
The thermostat sensor plays an important role in determining the temperature of the air that blows into the coil. Most room air conditioners have such sensors, and you have to make sure that it is in the proper position. It has to be next to the coil but is not in direct contact with it. A thermostat that is not installed properly or in the correct position could cause the entire unit to not function based on the settings that you gave it. Some units may even begin to behave erratically because of it, so this is certainly an issue that needs to be addressed as soon as it manifests itself.
