HVAC
The first time I heard someone say, “Just check the LRA and estimate the tonnage,” I honestly had no idea what they meant. I was helping a local HVAC technician inspect an old outdoor AC unit with a faded nameplate. The cooling capacity label was unreadable, but the compressor sticker still showed one thing clearly: … Read more
In an HVAC system, the expansion valve plays a small but very important role in the cooling process. After the refrigerant leaves the condenser as a high-pressure liquid, it passes through the expansion valve, where its pressure suddenly drops. This drop in pressure causes the refrigerant to cool quickly and partially turn into a low-temperature … Read more
I still remember the first time I helped install a split air conditioner at a friend’s house. Honestly, I thought it would be simple after watching a few online videos. “Just mount the indoor unit and connect some pipes,” I told myself. But after drilling a slightly crooked hole in the wall, forgetting to check … Read more
A couple of summers ago, my air conditioner stopped working right in the middle of a heatwave. At first, I thought it was a small issue. I lowered the thermostat temperature, cleaned the remote, and even restarted the breaker. Nothing worked. The room still felt hot and humid, and the fan was only pushing warm … Read more
Once I made the classic mistake almost everyone makes when buying an air conditioner for the first time. I walked into a store thinking, “An AC is just an AC.” I picked the cheapest one that looked decent, brought it home, and within a week I realized I had chosen the completely wrong type for … Read more
Cleaning the coils of your air conditioner is among the best ways to improve cooling efficiency and save on electricity. When the coils of an air conditioning unit are dirty (i.e. when dirt has accumulated on the coils). The coils will become very hot while trying to cool down your house i.e. the coils will … Read more
It is necessary to have the right amount of refrigerant in your air conditioner (AC) in order to maximize efficiency, lower energy costs, and prolong the overall life of the system. If the refrigerant level is too low or not appropriate, you may experience poor cooling performance, excessive electricity bills, and a compressor failure. This … Read more
The compressor is the heart of an air conditioner. Without it, an air conditioner cannot provide cooling. Essentially, the compressor circulates the refrigerant, compresses low-pressure gas into high-pressure gas, and thereby helps remove heat from the air inside the building. what are the types of Air Conditioners Compressors. Therefore, manufacturers equip different air conditioners with … Read more
Capacitors, although they are small in size, are very important components providing electrical energy for many types of equipment or circuits. The use of capacitors can be found in air conditioning units, refrigerators, washing machines, and power supplies. And are used to provide starting power and run motors efficiently. When a capacitor fails, a device … Read more
