The straightforward answer to this question is “no.” Modern central air conditioning systems are complex refrigeration devices, and to work on them requires special training as well as tools not easily available to the consumer.
The biggest obstacle against trying to do DIY work on an AC is the difficulty in diagnosing what’s causing a malfunction in the first place. For example, if an air conditioner keeps shutting down early (short-cycling), it could be due to a miscalibrated thermostat, leaking refrigerant, a reduction in airflow, dirty condenser coils, etc. Trying to repair a problem yourself will involve too much guesswork and too much that can go wrong.
Springtime! The weather is already warmer, and you may have even turned on your air conditioning system for a few hours to cool down. That’s great because it means we’re nearing the relaxing days of summer.
You could call this post “Summer Thermostat Best Practices,” although maybe that sounds a bit too business-like. Just think of this post as your short, simple guide to undo some bad habits many homeowners get into when it comes to setting the thermostat.
If we could choose one component of an air conditioning system as the most important, it would be the compressor. All parts of an air conditioner are vital for it to operate well, and malfunctions in any of them are a reason to call for 
If you’re asking this question, you may be on the verge of making a big mistake: hiring a non-professional to fix your AC or install a new one rather than calling a 
When you listen closely to the sound your central air conditioner makes while it runs, you’ll occasionally catch the noise of water dripping. Your AC doesn’t use water to provide cooling (that’s how evaporative coolers work, an entirely different type of cooling system), but water is a byproduct of how it operates.
You’ve turned on your air conditioner at least once this season, and you can expect it to remain running during most days for the near future. That can make it extra worrying if the AC already appears to be having problems. This happens sometimes: an air conditioner begins the summer seasons a few steps behind. It may be a minor issue—or the air conditioning system may soon be many steps behind and in danger of failing when you need it the most. 
Spring starts in late March, although that doesn’t mean we automatically receive warmer weather. This is a fickle month where temperatures can swing from extremes, and the heating system warming your home will still need to run on the regular.
The whole point of using a whole-house cooling system is to cool your whole house with just one cooling system, right? That means cooling the entire house evenly. If your air conditioner is failing to do this, then it is failing in one of the most basic areas of its expectations. Do not allow your AC to come up short, and do not settle for anything less than a great performance from your system throughout your entire home.
A heating system like a gas furnace or an old oil boiler creates new heat by combusting fuel. An air conditioner, on the other hand, doesn’t create new “coolness”. That coolness that you feel as the AC circulates cooled air throughout your home is actually the lack of heat. How does an air conditioner remove heat from the air in your home? Through the evaporation of refrigerant.
