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 decide 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 (more…)
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…)
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 between the air conditioner condenser to the heat pump condenser unless you looked inside the unit and were 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 that pumps the refrigerant through the HVAC air conditioning system. (more…)
Air Conditioner Sequence of Operation - When a technician is troubleshooting an air conditioner problem it is important that the technician understands the air conditioner sequence of operation for that equipment. When there is a problem with the equipment, including air conditioners, the technician will know the problem if the equipment or air conditioner does not follow the sequence of operation. Sometimes it is that easy, and other times it is not that easy when troubleshooting any HVAC equipment. However, it is important to understand the sequence of operation for air conditioning so the technician can troubleshoot the problem. (more…)
Home Humidity Control | Why Its Important for Comfort & Health - Humidity is important to our home and health and it is important to maintain the correct humidity in our homes and workplaces for our health. What is humidity? Humidity is simply little water droplets in the air. Cold air is nearly saturated with these little water droplets because the contents of cold air allow the air to hold more water droplets or humidity. As air is heated it expands and holds less humidity. (more…)
Home Humidity Problems - HIGH HUMIDITY 60 % +. Within the last month, I moved into a new house. It has drywall and not plaster walls. The furnace and hot water tank were installed a week or so before we moved into the house. Last week we determined that there is a humidity issue when the windows were sweating. We are trying to determine the source of the humidity. The contractor feels it may be the high-efficiency furnace. I have a Lennox g61mp. The combustion air is pulled from within the unfinished basement. Should the air be pulled from the outside? The gases are vented via PVC pipe which slopes back to the furnace. (more…)
Air Conditioner Condensation Water Dripping - It’s the heat of summer or even the beginning of the season. You turn on your air conditioner for the first time. Hopefully, you’ve already had all the preventive maintenance checks done, and there are no problems. Everything is working fine, at least for now. Suddenly you notice water around the air conditioner, and you know you have a problem. You have air conditioner condensation dripping water everywhere. (more…)
Air Conditioner Condensation Problems - It is important for air conditioning preventive maintenance to be performed on your system to avoid problems. Condensation water leaking near the air handling unit can be avoided with proper air conditioning repair and preventive maintenance. Normally this is a very simple problem that can be fixed in less than 30 minutes. Here is a list of what can cause water around the outside of the air conditioning air handler unit. (more…)
HVAC Tip - Some people refer to refrigerant as Freon. So when something is wrong with their HVAC system they say, “I have a Freon leak”. Freon is a name trademarked by Dupont for R-22. R-22 is being phased out because it contains chlorine. While Freon will soon be a thing of the past, the name Freon has found its way in our lexicon as a reference to refrigerant, any type of refrigerant.
