Accurate Charging Methods of Central Air Conditioners


The charging (of an air conditioning system) alone can have a substantial impact on system operation costs. A few percentage points of over-or undercharge can raise electricity consumption significantly and shorten the life of the compressor." <span style="font-weight: bold;">You must invest in the proper tools, training and methodology to accurately charge an Air Conditioning system so that it works at maximum efficiency. Using the Thermocharge method to charge your air conditioning systems to the exact charge needed will save hundreds to thousands of dollars in electricity and maintenance costs over the years! </span><br /> Thermocharging method<span style="font-weight: bold;"> </span> <p style="font-weight: bold;">Skilled technicians will <b>"Thermocharge"</b> your air conditioning system with an exact refrigerant charge. This procedure produces an exact charge . . .not approximate, but exact. The Thermocharge method requires special equipment and training to use. Your installer uses the following instruments:<br /> <p style="font-weight: bold;"><br /> <ul> <li>1. An electronic thermometer</li> <li>2. Sling psychrometer or electronic humidity measuring device</li> <li>3. Refrigerant pressure gauges</li> <li>4. Accucharge slide rule calculator</li></ul> <p style="font-weight: bold;"> Here the tech is using the sling psychrometer to obtain the indoor humidity and indoor air temperature. He will double-check his figures with the electronic thermometer laying on the table. He will also verify the readings with an electronic psychrometer. <br /> <p style="font-weight: bold;"> After recording the indoor humidity and temperature the tech will go to the outside condensing unit to take additional readings. These are the following: <br /> <br /> <ul> <li>1. Outdoor temperature</li> <li>2. Indoor humidity</li> <li>3. Temperature difference, between air entering the evaporator coil, and the air leaving the evaporator coil</li> <li>4. Suction line temperature</li> <li>5. Suction line pressure</li> <li>6. Liquid line pressure (smaller copper line)</li></ul> <p style="font-weight: bold;">Enter this information into his special slide rule calculator to determine the exact amount of refrigerant to put into your air conditioner. <br /> <p style="font-weight: bold;">Let it run for about ten minutes to verify his figures. If there are any discrepancies, start the procedure all over again from the beginning. <br /> <p style="font-weight: bold;"> This Thermocharging method of charging an air conditioning system takes time and patience, but it guarantees that theair conditioning system will operate at peak efficiency all season long. <br /> How does accurate refrigerant charging help? <span style="font-weight: bold;"> </span> <ul> <li><b>Improved comfort</b> - A improperly charged air conditioner will not dehumidify properly.<br /><br /></li> <li><b>Lower maintenance costs </b> - A poorly charged system will not properly cool or lubricate the compressor . . .significantly shortening its life.<br /><br /></li> <li><b>Better cooling and efficiency</b> - Improper charging means that the air conditioner will not provide enough cooling on hot days, causing the system to run longer.<br /><br /> </li> <li><b>Improved efficiency and lower electric bills</b> - Poor heat transfer from improper charging results in increased power consumption. A 15% undercharge or overcharge can result in a 25% decrease in efficiency. This means that the homeowner's electric bill will be 25% higher than necessary. As the charge drops farther, efficiency decreases faster to 50% or more.<br /><br /></li> <li><b>Increased reliability</b> - A poorly charged system will not properly cool or lubricate the compressor . . . significantly shortening its life. Even if you have extended warranty by a heating company, you will either be greatly inconvenienced or even end up paying for the repair if the company stalls and you end up paying another company for the work . . .a $300-$700 repair that will void the warranty. </li></ul>

Air Conditioning Tips & Tricks You Must Know!


  • Try setting your thermostat between 72°F and 78°F. Each degree setting below 78°F will increase your energy consumption by approximately 8%. As you can see, that can add up to a lot of money over a year.
  • Inspect and clean both the indoor and outdoor AC/Heating coils. The indoor coil in your air conditioner acts as a magnet for dust because it is constantly wetted during the cooling season. Dirt build-up on the indoor coil is the single most common cause of poor efficiency. The outdoor coil must also be checked periodically for dirt build-up and cleaned if necessary.
  • Check the refrigerant charge. The circulating fluid in your air conditioner is a special refrigerant gas that is put in when the system is installed. If the system is overcharged or undercharged with refrigerant, it will not work properly. You may need a service contractorto check the fluid and adjust it appropriately.
  • Use bath and kitchen fans sparsely when you are running the air conditioning system.
  • Reduce the cooling load by using cost-effective conservation measures. For example, effectively shade east and west windows. When possible, delay heat-generating activities, such as dishwashing or baking, until the evening on hot days.
  • Try to not use a dehumidifier at the same time your air conditioner is operating. The dehumidifier will increase the cooling load and force the air conditioner to work harder, which in turn increases your utility bill.
  • Over most of the cooling season, keep the house closed tight during the day. Don’t let in unwanted heat and humidity. If practical, ventilate at night either naturally or with fans.
Room Air Conditioning Units
  • The unit should be level when installed, so that the inside drainage system and other mechanisms operate efficiently. If possible, install the unit in a shaded spot on your home’s north or east side. Direct sunshine on the unit’s outdoor heat exchanger decreases efficiency by as much as 10%. You can plant trees and shrubs to shade the air conditioner, but do not block the airflow.
  • Set the fan speed on high, except on very humid days. When humidity is high, set the fan speed on low for more comfort. The low speed on humid days will cool your home better and will remove more moisture from the air because of slower air movement through the cooling equipment. Consider using an interior fan in conjunction with your window air conditioner to spread the cooled air more effectively through your home without greatly increasing electricity use.
  • Set your air conditioner’s thermostat as high as comfortably possible in the summer. The less difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be. And don’t set your thermostat at a slighter setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in excessive cooling and, therefore, unnecessary expense.
  • Don’t place lamps or televisions near your air-conditioner’s thermostat. The thermostat senses heat from these appliances, which can cause the air conditioner to run longer than necessary.
Proper maintenance of your air conditioner will also save energy. Be sure to do the following:
  • At the start of each cooling season, inspect the seal between the air conditioner and the window frame to ensure it makes contact with the unit’s metal case. Moisture can damage this seal, allowing cool air to escape from your house.
  • Check your unit’s air filter once a month and clean or replace filters as necessary. Keeping the filter clean can lower your air conditioner’s energy consumption by 5% to 15%.
  • Occasionally pass a stiff wire through the unit’s drain channels. Clogged drain channels prevent a unit from reducing humidity, and the resulting excess moisture may discolor walls or carpet.
  • *In the winter, either cover your room air conditioner or remove and store it.

To much humidity coming from unit into house


An air conditioner removes heat (cools), and removes humidity. Your unit is either undersized or there's a leakage of outdoor air entering the conditioned space.

What would be the reason it leaks water


Just as a cold can of soda condenses the moisture in the air as it contacts the cold surface, so does an Air conditioner, it is part of the "conditioning" not simply temperature reduction. As you may know in New York city for example 95F is a heat stroke warning temperature if the humidity is very high, Miami beach is also very humid, humidity affects the comfort level at a given temperature tremendously.

Save cost with some precautions


Precautions to be taken in air conditioners and to save cost.

These are some useful precautions to be taken in air conditioners (A/C).Improper refrigerant charge can damage your compressor, which is the heart of your air conditioning system; this is an expensive air conditioner repair. Systems improperly charged will cause increased electric bills because this will reduce the efficiency of your air conditioning system. The proper refrigerant charge will provide longer equipment life, lower your utility bills and reduce the need for air conditioning service.
A dirty condenser coil (outside unit) will reduce your air conditioning systems ability to remove and reject heat from your home. This will cause your system to run longer and increase your electric bills. The benefit of a clean condenser coil is proper heat rejection, reduced run time and lower energy bills. A dirty air conditioning condenser can lead to system failure and the need for you air conditioner to be repaired, dirt and house dust that escapes through your air conditioning filter can cling to the cold moist coil. This will restrict the air flow through the coil reducing your air conditioning system of performance and capacity. Maintaining the evaporator coil will ensure that proper air flow is delivered to all areas of your home, increase comfort levels, provide a cleaner healthier indoor environment. Inspecting and changing your air filter on a monthly basis will help prevent air conditioner repairs.
As your air conditioning system removes heat from your home, humidity is extracted from the air. The condensation created by warmer air passing over a cold coil must be drained from your system. This is done through a condensate drain line. The drain must be checked and cleared of algae build up or foreign particles clogging the drain, which could cause water damage to the ceiling or floors of your home. By keeping your air conditioner drain line clear you will reduce the need for air conditioning service and overflow problems which can result in water damage. Proper draining will also aid in maintaining indoor humidity levels.
Cause of air flow
Dirty blower wheels can affect the air flow to your home; limit your air conditioning system's capacity and your comfort. It can also spread dust particles which irritate sinus and allergies. A clean blower wheel and fan motor will provide maximum air flow, improved comfort levels and proper cooling. Most of air conditioner repairs are caused by dirt and the lack of maintenance.
Cause of electrical panel
Your thermostat should be properly calibrated. This will ensure accurate temperature control and operating cycle. This will save you on operating cost and assure your comfort level. Moving parts in need of lubrication can cause increased electrical consumption and air conditioner repairs. This is due to additional power required to overcome the resistance in motors and drive shafts that are not lubricated. Proper system lubrication will offer smooth motor and shaft operation, extended part life and less air conditioner repairs. The electrical components on your air conditioning system should be inspected regularly for signs of wear. Faulty electrical components can lead to very expensive air conditioning repairs. A thorough inspection will reduce the need for air conditioner service if the faulty or worn parts are replaced when found.
Carrying this tips help reduce the amount of air conditioner repairs you will encounter over your air conditioning systems lifespan. If you are in need of air conditioner service make sure the company you choose is licensed and insured to do the required repair work (warranty) .

Will you be able to give an easy index Ton/SQF for A/C capacity to be installed in South Florida? Thansks.


I have a couple of sites I can share with you. These are quick, easy, basic calculators to give you a general idea. Because of the conditions in South Florida - High Temperatures & High Humidity, you can expect better results from a professional analysis as proper sizing is critical for satisfactory operation.

This is for whole house air conditioning sizing:

Mitsubishi Through the Wall Unit Does Not Remove Humidity


You were told incorectly. From what you are describing the unit is oversized for your space.

All Air conditioners remove humidity. In fact the Air conditioner was invented by accedent by Mr carrier when he was trying to invent a machine to remove humidity. He discovered that by drawing air accross a cold coil the humidity drained off the coil. He also discovered that it was a mighty effective way to cool large quantities of air, and we then had "Carrier" air conditioning systems.

When a system is to large for the area it is to cool, it will cool the air in that small area so fast that the humidity starts to condense in the room before it can be pulled through the evaprator coil.

In this case, the solution would to be either replace the unit with a smaller one.
Increase the area to be cooled. (open doors to other rooms etc). or use the dehumidifier.

How many square foot is the space you are trying to cool?
What size is the AC unit? (in "tons")

WINDOW AIR CONDITIONER SHUT ITSELF OFF


Some units have a dehumidify setting to overcome this as they go through a defrost. You can either manually defrost running on heating for a few minutes, or have it defrost when it goes out on fault as happened.

I dont know if my new humidifier is working properly


Hello Mary, Where are you located at? if its cold outside? Then whats going on is that even though the outside humidity is say 80 percent humidity on the inside of oyur house even though oyu have the dehumidifier set at say 50 percent by the time the air is heated up there is not that much humidity in it because then the air heats up by the furnance it takes and dries the air out in the process. I know it sounds confusing but if you have ever had a humidifier in you house and it get real cold outside if oyu don't turn the humiditfier down to a lower setting then waht happens is that your windows will start to sweat and run water down to the sill because its condensing on the cold surface of the window. Hope that this helps you.
