Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. (Minisplit ductless systems are used in these situations.) Outside of North America, packaged systems are only used in limited applications involving large indoor space such as stadiums, theatres or exhibition halls.
I have a recurring problem of having to have freon added to my A/C system. I have even replaced both units inside and outside but seem to have the same problem. I believe that it must be in the lines between the outside and inside. Is there anything that can be put into the lines to seal any leaks if this is the problem? If not is it advised that the lines be replaced?

The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%.
You haven’t had a ductwork inspection in years: According to PG&E, the average home’s ductwork leaks up to 30 percent of its air before it actually reaches your living space. That means you’re still paying for the energy used to cool the air—without getting the relief of a cool home. Hire a technician to come take a look at your system; they can perform what’s called a duct-leakage test, which measures how much air is escaping the system. If it turns out your ducts are faulty or have significant gaps, a technician should be able to seal them up or replace your pipes—meaning you might not need a complete system overhaul. However, keep in mind that modern HVAC units are almost always more efficient thanks to technology advancements. In the end, you have to weigh your options: will you need to perform repairs each month?
Here’s a simple test to try on your own: When it’s hotter than 80 degrees outside, turn on your AC unit, and set it to well below room temperature. Let it run for 15 minutes, then use a thermometer to check just outside the return duct (the area where air flows in to be cooled). Now take a temperature reading just outside the strongest, most easily accessible vent (where cool air should be flowing out). Subtract the second reading from the first. If the difference between these two is fewer than 14 degrees, your HVAC unit might need work. 
Tony from HVAC came out on Sunday morning and did a fantastic job of immediately diagnosing the issue, quickly fixing the problem, and honoring the coupons I had.  When I initially called on Saturday morning, I had a lot of trouble with their answering service getting their wires crossed with their technicians.  However, Tony called me back and made it right.  He even pointed out an issue that is in the horizon that I should look at (without charging me extra or telling me I had to fix it right now). Great service!
Before selecting the installation location of air conditioner, several main factors need to be considered. First of all, the direction of air flow from the indoor units should not fall on the place of rest or work area. Secondly, there should not be any obstacles on the way of the airflow that might prevent it from covering the space of the premises as much as possible. The outdoor unit must also be located in an open space, otherwise the heat from the house will not be effectively discharged outside and the productivity of the entire system will drop sharply. It is highly advisable to install the air conditioner units in easily accessible places, for further maintenance during operation.

In hot weather, air conditioning can prevent heat stroke, dehydration from excessive sweating and other problems related to hyperthermia. Heat waves are the most lethal type of weather phenomenon in developed countries. Air conditioning (including filtration, humidification, cooling and disinfection) can be used to provide a clean, safe, hypoallergenic atmosphere in hospital operating rooms and other environments where proper atmosphere is critical to patient safety and well-being. It is sometimes recommended for home use by people with allergies.
In the United States, HVAC engineers generally are members of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), EPA Universal CFC certified (for installation and service of CFC HVAC devices), or locally engineer certified such as a Special to Chief Boilers License issued by the state or, in some jurisdictions, the city. ASHRAE is an international technical society for all individuals and organizations interested in HVAC. The Society, organized into regions, chapters, and student branches, allows exchange of HVAC knowledge and experiences for the benefit of the field's practitioners and the public. ASHRAE provides many opportunities to participate in the development of new knowledge via, for example, research and its many technical committees. These committees typically meet twice per year at the ASHRAE Annual and Winter Meetings. A popular product show, the AHR Expo, is held in conjunction with each winter meeting. The Society has approximately 50,000 members and has headquarters in Atlanta, Georgia.
The first air conditioners and refrigerators employed toxic or flammable gases, such as ammonia, methyl chloride, or propane, that could result in fatal accidents when they leaked. Thomas Midgley, Jr. created the first non-flammable, non-toxic chlorofluorocarbon gas, Freon, in 1928. The name is a trademark name owned by DuPont for any chlorofluorocarbon (CFC), hydrochlorofluorocarbon (HCFC), or hydrofluorocarbon (HFC) refrigerant. The refrigerant names include a number indicating the molecular composition (e.g., R-11, R-12, R-22, R-134A). The blend most used in direct-expansion home and building comfort cooling is an HCFC known as chlorodifluoromethane (R-22).
"Customer service was great, and the price was in-line with other places, and fast service. We had a whole replacement of the outside and inside. I would have liked to see a better install for the furnace and new thermostat - the new thermostat should have gone where the old one was, and even tho the new furnace was a tight fit, they didn't offer to come back and repair the case molding, or give me a discount on the damage done, and I believe they should have put a disconnect box on the outside of the home, to make it easier for any future repairs needed. Other than that, am very happy with the cooling and heating!"
Stay away front his company!!! In 2008 I had the company send Rick a technician to do warranty work on my new house. I complained about my house being hot in the summer. Tech said that I had a delta t of 14 degrees (the difference of temp coming into the return and out the supply) and that system was functioning properly. Unfortunately I took their word. After 8 years of being hot I called a reputable company to come and check my system again. The HVAC system still operating with a delta t of 14 degrees. The new company looked at my HVAC system owner manual. They calculated my dry bulb temp and wet bulb temp and used the chart in the owners manual to determine that the system wasn't functioning properly. After the new company came a put two pounds of freon into my HVAC system I now have a 20 degree Delta t. Do not do business with this company not trust worthy!

When central air conditioning service fails during a heat spell, you may have to wait days for an HVAC repair technician or a ac contractor to show up, and you’ll probably pay at least several hundred for the repair. But if you’re comfortable working around electricity and are willing to spend about $50 on parts, you can probably repair your air conditioning service yourself in about two hours and save about $225 on parts markup and labor.
