Being a Mechanical Engineer, I can understand how Air conditioner works. There is no need to charge gas or refrigerant (which can be R-22,R-12 or R-134-a (Latest)) if your AC works well or even at lower performance level. There are many components in AC which might degrade the performance such as compressor, condenser and capillary tube. You should first consult technician of refrigeration and air conditioner. So, do not simply blame gas when your AC's performance is down.Second thing, never try to fill or charge gas/refrigerant on your own. It is very RISKY. Some refrigerants are very toxic. It may harm to your health too. And also you cannot always get 100% pure refrigerant/gas once your AC is depleted with gas.Now coming to the procedure, You should do the followings to charge the gas in AC.1. First find out the outlet with valve where we can exhaust the gas from AC. 2. You need to evacuate the system by vacuum pump. This involves removal of moisture and air entrapped during exhaust process.3.

Get mass flow meter ready and connect it in line between compressor and charging cylinder. Start the charging process initially slowly and then at required rate. You cannot fill more than recommended quantity as pressure-volume relation might change the phase change process for refrigerant. This is what you should know.Before refilling the gas in the air conditioner check the air pressure there. If pressure of gas inside your A.C. is less than 65 PSI - 70 PSI then go for refilling other wise not.I would suggest you to call the brand engineer because in case local mechanic fails to solve your problem or if the problem persists after refilling then time as well as money goes waste. Call the brand engineer and ask him for proper analysis. Process:-They have a small pressure checking metre which when attached to the highlighted vent shows the pressure of the A.C. If the pressure shows there less than 60 then the mechanic would connect a small cylinder to that vent and refill the gas in you A.C. hence you can't fill the gas yourself.

Without central air conditioning running throughout the home, residents may get uncomfortably hot and sticky during the warmer summer months. While fans can be a temporary solution, they won't do much to combat particularly high temperatures or humidity. how much for a 4 ton ac unitInstalling a window AC unit can be a smart choice for homeowners who are on a limited budget. replacing a central air conditioning unit costUse this guide to learn more about the pros and cons of window AC units as well as the various costs associated with buying and installing them.window ac unit capacity Average Minimum Cost of Window AC Units: $150 per unit Average Maximum Cost of Window AC Units: $750 per unit Advantages of a Window AC Unit

The major advantages of having a window AC unit as the primary means of cooling a space include localized cooling, low costs and simple installation. Rather than paying to cool an entire home whenever the resident feels warm, they can turn on a window AC unit and enjoy rapid cooling when and where it is needed. In addition, installing a window AC unit is straightforward, and most homeowners are able to do it themselves or with the help of a friend. Not needing professional installation can keep costs low. Finally, the expense of buying a window AC unit is marginal compared to the cost of installing an entire whole-home split-system or ductwork to run cool air. Disadvantages of a Window AC Unit While there are advantages to have a window AC unit, homeowners should also be aware of the potential drawbacks. These include noise, uneven cooling in the home, reduced curb appeal and limited views from inside the house. The noise of a window AC unit can be frustrating, especially when used in bedrooms, as it can make it hard to sleep.

Unless there are window units in every room of the house, they can also result in uneven cooling. Since window units are visible from inside the home as well as from the exterior of the home, they reduce curb appeal and limit interior views, which can both reduce the total value of the home. Choosing the Right BTU for the Space A primary factor that will influence the cost of the window AC unit will be BTU, or British Thermal Unit, that dictates how much energy is used. To cool a small 200 square-foot room, for example, a window AC unit with just 6,000 BTUs may be sufficient. For a larger space, such as a 900 square-foot room, homeowners will need closer to 15,000 BTUs, which will increase the price of the unit and the user's monthly energy bill. Factors that Affect the Cost of Window AC Units Additional elements that might influence the total cost of a window AC unit could include the following: Size of the window AC unit Quality of the unit Whether the window AC unit is new or used

Higher EER, or Energy Efficiency Ratings, increase purchase cost Multiple settings for cooling and fan function Manual vs electronic control can affect price Top Articles on AC Window UnitOrder before the summer rush and save up to 20%! 1.
