Things You Need To Know About Recharging the AC System Gas

The air conditioning unit like the central air conditioners has a prime duty to keep the temperature of the place cool, and if it is not working well, perhaps it was due to the size of the place or some defects. We heard advises on proper maintenance and cleaning of the vital parts of the air conditioner but did you know that the refrigerant also needs to be recharged?

In a real sense, when we talk about recharging the air conditioning gas system we mean refilling the system with refrigerant. This happens. The air conditioning unit utilizes refrigerant to sip out the warmth of the air and transmit the air to the compressor but if the level of refrigerant is very low then transferring of heat is not possible and it needs a professional HVAC technician to do this as this can be dangerous if not properly done.

Questions Regarding The Recharge Of AC System Gas:

Below are some questions you might have in your mind. We did you some effort to clear those queries and doubts, so check them out:

  1. Do I need to recharge the air conditioning system gas?

Apparently, the air conditioning unit was created with refrigerant that could last its lifetime or more, but sometimes, leaks will make it insufficient. That is why when an air conditioning technician inspects the system and would tell that there are leaks, then possibly some of the refrigerants of the air conditioning unit had already leaked out.

  1. What are the signs that your air conditioning unit needs a recharge?

If you notice that the vents of the AC are fanning room air temperature, then there is a big potential that you need to recharge it. The main reason for this might be a damaged thermostat where one can feel humidity even if the air conditioning unit is working.

  1. My air conditioning unit builds ice on it; do you think I need to recharge the AC system gas?

Definitely. The answer to this question is yes. One of the reasons why there is frost on the air conditioning unit is when the refrigerant is already at a low level due to some leak, and the pipe could not transmit the air to the system, and it will form ice or frost around the system.

  1. How did that happen if I regularly call for maintenance and inspection for my air conditioner?

The regular check-ups and maintenance will only detect the early signs or symptoms of the air conditioner, but there are instances that worn out and damage is brought by some other factors so you should not be skeptical when an HVAC technician tells that your AC needs a recharge.

  1. Is the leaks only reason for the air conditioning unit to be recharged?

No, though leaks can be the number one reason why air conditioners need recharge there are certain instances that an air conditioner needs recharge because of the manufacturing quality. If your air conditioning unit is still new and you already had seen leaks, you can call the dealer or makers of the AC and report them the problem of the system. Leaks are most likely to happen only with AC unit that aged between ten to twenty years old.

  1. Is recharging the gas system of the air conditioning unit a prudent decision? Or it is wiser to replace the AC unit?

Whatever the causes of the leaks, you need replacement either for some parts of the air conditioning unit or the whole unit itself. The answer to that will depend whether how big is the damage and the cost of expenses to get it fixed again. Sometimes it is good to recharge the gas system of the air conditioning unit, and sometimes it is best to buy new AC unit.

It might be difficult to trust the words or advise of the HVAC technician alone because at the back of our minds we knew that they are also protecting their interests. But the best advice we can give you in deciding whether to replace or recharge the AC system gas is to check if the leak is small. Is it is just small then it is wise to have it recharge as the damage may just cost little for repair? Otherwise, you need to ask estimated cost so that you get clear calculations on how much you have to spend to fix your AC. Find our more at aircon spare part singapore.


Little History and Background of Rusq

Reference & User Services Quarterly is the official journal of the Reference and User Services Association of the American Library Association. Its purpose is to disseminate information of interest to reference librarians, information specialists, and other professionals involved in user-oriented library services. This Web site serves as an online companion to the print edition.

Manuscript Preparation

Please follow these procedures when preparing manuscripts to be submitted to RUSQ. Manuscripts that fail to comply with RUSQ style may be returned without evaluation.


Submit only original, unpublished articles on subjects within RUSQ‘s scope. Manuscripts based on the work of RUSA committees will only be considered for the columns sections of RUSQ. Articles of four thousand to seven thousand words are preferred.


Write the article in a grammatically correct, simple, readable style. Remember that the author is responsible for the accuracy of all statements in the article, including the accuracy of references and quotations.

Consult the Merriam-Webster’s Collegiate Dictionary, 11th ed., or the Merriam-Webster Online Dictionary ( for questions relating to spelling and word division.

As the authority for punctuation, capitalization, abbreviations, note forms, etc., consult The Chicago Manual of Style (CMOS), 15th ed. (Univ. of Chicago Pr., 2003). CMOS has a companion website (

Give the article a brief title; if the title is not descriptive of content, add a brief subtitle. On a separate page give the title, the name(s) of the author(s), and the title and affiliation of each. Manuscripts based on conference presentations should identify the conference by name and date on this page.

On a separate page, type the title and subtitle, followed by a brief abstract typed double-spaced. Do not identify the author(s) here or elsewhere in the manuscript.

Prepare tables, figures, illustrations, and photographs. Each table should be provided as a separate word processing or MS Excel file. It should be given an Arabic number and a title and cited in the text. Tables, figures, illustrations, and photographs should be numbered in the order in which they are first referenced in the text. Each column in a table should have a heading. Table footnotes and sources, if any, should be typed double-spaced beneath the table.

Each figure should be provided as an individual file, given an Arabic number and a title, and be cited by number in the text. Computer-generated figures should be embedded in Word files or provided as Excel files; Excel files are preferred. Resolution for all figures must be at least 300 dots per inch.

Screen captures, such as those of Web sites, must be at high resolution (300 dpi) and formatted for black-and-white or grayscale reproduction. URLs for screen captures must be provided.

When selecting or preparing drawings or photographs, keep in mind that they should be large enough and clear enough to permit a reduction of one-half to one-third.

Avoid referring to tables and figures with phrases such as “the following,” “above,” or “below”; it may be impossible to place the tables or figures to correspond. Refer always to “table 2,” “figure 6,” and so on.

RUSQ uses the numbered endnote style described in chapter 16 of CMOS. Endnote numbers should appear in the text as superscripts at the ends of sentences. When more than one item is referenced in a sentence, a single endnote number should be used and the items included in the endnote as in example 13 below. Automatic embedded footnote or embedded endnote features of word processors should not be used.
