In a previous article, we discussed the cost to recharge a home air conditioner or heat pump on your Charlotte area central HVAC system, and in this Charlotte HVAC Guide, we are going to look at how many pounds of freon or refrigerant a system can hold. The general rule amount that can be estimated is in the 2-4 pounds per ton of cooling for your system.

Disclaimer: This rule of thumb is VERY general and there are several variables that come into play. My Carrier 3-ton system may use 4-5 pounds, while your Goodman heat pump may use 5-6. The ONLY way to know for sure is to read the label on the side of the unit, and have your installer or service company provide the info for you. As always, we recommend comparison shopping for installation and repairs as often as you can. Just like any other factor in pricing, you may find that 3 Charlotte AC repair contractors have 3 completely different prices for the same product or service. Take a look at the important variables that can affect how many pounds of freon your AC or Heat Pump may need. Probably one of the biggest factors, the size of your home AC or heat pump is going to have a significant effect on the amount of freon it uses on its own, but it will also have a downwind effect on several of the other factors listed below. For example, a larger condensing unit, needs a larger liquid line on the lineset… which also means more capacity.

Length and Size of Copper Lineset The farther distance between the condensing unit and the evaporator coil, means a longer lineset is used to connect the two. Most AC units come from the factory with enough of a charge for the unit, and 15 feet of lineset. Longer distances require additional freon. Larger capacity units also use a larger diameter tubing on the lineset, which will require more freon. SEER Rating, or Operating Efficiency If you have seen a 10 SEER system, you know they are roughly 20-30 inches tall with a 24 inch base. Essentially, a nice, small footprint. A comparable 15 SEER condensing unit may be 4 feet tall, with a 36 inch base, and be 2-3 times the size of the lower efficiency unit. This is due to all the extra coil surface required to generate the higher efficiency cooling, and thus… more freon is needed to fully charge the coil. It’s common to use a larger evaporator coil with an AC unit. In most cases, it can provide higher efficiency due to the larger coil area.

Along with the added coil surface, you may need additional freon capacity to fill it. A split system, where the condensing unit is outside and the air handler, furnace and coil are inside (aka Split) is going to have to accommodate for different coils, linesets, and several other factors that were determined by the installer when the unit was first put into use.ac unit side panels A Packaged HVAC System, or “All in One” has everything in one cabinet outside the home. classic car ac unitsThere are no different coil sizes to deal with and the lines connecting everything are self-contained in the same box.single room ac and heating units Fortunately, most Charlotte AC Contractors are honest and treat customers fairly. If you think you may have been taken advantage of during a recent home ac recharge, make sure you ask them about it and give them a fair chance to explain their pricing and reasons for using the amount of refrigerant they did.

Refrigeration tubing and electrical circuitry will pass through the building envelope.

You will find that the cost of average central A/C varies by type of unit, its cooling capacity and efficiency rating, preparation and special needs, and the labor rate.In the following tables the Labor Cost figure is what the able DIY person should expect to save by performing the corresponding tasks.Central A/C: central unit added to existing furnace ducts to cool 1,000 sq.ft.; include delivery, all material, equipment, and waste.ItemUnit CostA/C unit: 24000 BTU (2 ton) cooling only, 230 VAC, pad mount; include plenum, piping, pad, and connections; with all trim, weather stripping, hardware, and touch-up.$2,990each1$2,990Upgrade: install new circuit; 30 feet of #10/3 wire in EMT exterior conduit; 30 amp breaker into existing space; wired into unit box.$2.16per foot32$68Material Cost$3,058each1$3,058+ Labor Cost (install AC unit)$38per hour16$608+ Labor Cost (upgrade circuit)$42per hour5$210Total Cost$3,876$3,876Central A/C: central unit added to existing furnace ducts to cool more than 2,000 sq.ft.;
