Air Conditioner Breaker Trips
I’ve been on several service calls where the problem was a tripped breaker. Of course, this causes the air conditioner to not function properly. Sometimes the problem with the air conditioner breaker trips are simple. However other times they are complex and result in a major repair. Here we’ll describe the two separate line voltage circuits for your split system air conditioner. We will also describe the possible causes that will make your air conditioner trip the breaker. If you have a package unit then you will have a single circuit for your air conditioner. A package unit is an air conditioner or heat pump in one package (all in one air conditioner). (more…)
Air Conditioner Circuit Board Troubleshooting Question - Hello, my name is Calvin and I am an HVAC Technician that graduated from a community college 2 years ago and I am still learning and know I have much more to learn before I think of myself as an expert. I have been running into a lot of circuit boards in air conditioners and heat pumps and I simply want to know what is the best way to troubleshoot and air conditioner circuit board? It seems like a lot of electronics and they never covered electronics too much in school.
I do understand basic electrical circuits and how circuits work in the air conditioners and heat pumps I work on but more and more systems are getting electronic circuit boards and I would like to know the best way to troubleshoot these air conditioner circuit boards so I can make the repair.Thanks for your help and I have learned a lot from your website. I look forward to your answer! (more…)
How Much Refrigerant for the Air Conditioner Question: What amount of Freon would it take to service a unit that services a 1200 square foot residential house if it were completely depleted?
How Much Refrigerant for the Air Conditioner
Answer: We get questions like this a lot in our email and this is not easily answered especially when we are talking about charging an air conditioner or heat system. No matter how the system lost its charge of refrigerant (many people refer to it as Freon which is technically incorrect) there are many things you need to know before attempting to charge the air conditioner or heat pump with refrigerant (or Freon is you prefer).

Air Conditioner Causes Water Damage Question - Hello, We need to ask you about water damage and how an air conditioner can cause this kind of damage. The whole ceiling in one of the rental properties just fell into the living room. All the drywall and insulation from the attic fell and caused damage to our tenants furniture. Thank God the tenants were not at home and injured when the ceiling fell in. The insurance adjuster came out and looked at it and said the problem was because the filter was clogged and air conditioner froze up inside the air handler.
Replace HVAC Compressor for Air Conditioner Repair - Question - Richard - I am an HVAC technician and have read all of your articles on refrigeration and compressors. Great information and it has helped to hone my skills and offer better service for my customers. Thanks! I was wondering what your experience is with replacing compressors. How do you arrive at the decision to replace a compressor technically speaking of course? Do you recommend repairing the air conditioner by replacing the compressor or replacing the central air conditioner? I look forward to reading your answer. Brett Des Moines, WA
Air Conditioner Condensing Unit Frozen - Richard - Early last month we turned our air conditioner on and it worked fine for a few days. Then I noticed it was getting a little warm in the house so I went around and checked the Air Conditioner. (more…)
Air Conditioner Components - There are big differences between heat pumps and air conditioners. While the air conditioner provides cooling the heat pump will provide heating and cooling so the components inside the air conditioner differ from the components inside the heat pump system. I constantly get emails from people asking if they can convert their air conditioner to a heat pump and of course they can but it is not recommended. I have even devoted an article to it for those who are considering converting their air conditioner to a heat pump. After all, if you sit a heat pump next to a condenser it would be impossible to tell the difference from the air conditioner condenser to the heat pump condenser unless you looked inside the unit and was able to identify the different components from a heat pump to an air conditioner. Here are the basic components of an air conditioner that make the air conditioner cool your home or business. (more…)
Delay Timers and the Air Conditioner Condenser - Air Conditioners are big HVAC refrigerators. Air Conditioners and Heat Pumps use the HVAC refrigeration cycle to transfer heat from a place where it is not wanted (inside absorbing heat with the evaporator coil) to a place that makes no difference (outside using the condensing unit)(in the cooling cycle). The heart of any HVAC air conditioning, heat pump, or refrigeration system is the compressor which pumps the refrigerant through the HVAC air conditioning system. (more…)
