![]() ![]() Screw CompressorĪ screw compressor is a rotary compressor that features a spiral screw action that helps keep the cooling process quieter, making this type of compressor more desirable in many home settings. This is a relatively efficient way to cool the air, and replacing this compressor runs about the same as other types, typically between $800 and $2,800, depending on the above factors. Rotary CompressorĪ roller inside a cylinder rotates to compress the liquid refrigerant in a rotary compressor. These units can be pretty loud when they’re running. A reciprocating compressor is generally limited to commercial AC units and employed in large buildings. Reciprocating CompressorĪlso known as a piston compressor, a reciprocating compressor compresses air via one or more moving pistons. Expect to pay $400 to $800 for compressor replacement in one of these small scroll units. ![]() This compressor has its limits and is typically found in small spaces (such as apartments). Scroll compressors feature spirals that do not come into contact, so no friction is created, and no lubrication is necessary. Many compressors require lubrication to operate smoothly, but a scroll compressor does not. A new central AC unit costs about $4,000 to $7,500, and replacing a complete HVAC system can cost between $1,000 and $10,000. However, these systems may not be suitable for everyone’s homes, so some homeowners will want to upgrade their standard HVAC system. If so, this may be the time to change to a more efficient unit, such as a heat pump or a mini-split. When an AC compressor starts having trouble, it may be around the end of the AC unit’s useful life, which averages 15 to 20 years. Typical warranties run from 5 to 10 years, but they don’t always cover all costs, so read the fine print to see if you can benefit from the compressor still being under warranty. If the AC or HVAC compressor is still under warranty, the manufacturer may pay most or all of the cost to replace the compressor-depending on why it went on the fritz. Only a professional HVAC technician can determine whether it’s better to try to fix the compressor rather than replace it based on the cause and extent of the damage. While replacing a standard AC compressor runs $1,200 nationally, repairing a compressor could run between $100 and $250. If the problem is minor, repairing the compressor is often less expensive than replacing it. Here are some more considerations when searching online for “air compressor repair near me.” Replacement vs. While most air conditioning compressor repair costs are straightforward, a few additional cost factors are also worth considering, depending on the unit’s brand and size. Photo: Additional Costs and Considerations Larger units: Bigger homes and high-end AC units feature pricier compressors that could run as much as $2,800 to replace.Central HVAC: This is the average type of AC unit found in many HVAC systems for small to medium-size homes, and the cost to replace a compressor for this type of unit is right around the national average of about $1,200.Mini-split: Homeowners can expect to pay around $800 or more to replace the compressor in a mini-split AC unit.Small central AC: Replacing a compressor in a small central AC, like one that may be found in an apartment, could run as little as $400.Window unit: A small compressor in a window unit could cost as little as $100 to replace.The type of compressor in the AC unit will also impact replacement cost. A 3-ton AC compressor would run somewhere in between. In a larger 5-ton unit, the cost to replace the compressor is closer to $0.03 to $0.05 per BTU. ![]() For example, the cost to replace a compressor in a 1.5-ton AC unit ranges from $0.04 to $0.08 per BTU. The larger the unit, the less (per BTU) the new compressor will cost. ![]() So, while the larger compressor has a higher overall replacement cost, it costs less per ton than the smaller compressor.Ī compressor’s BTU rating denotes how much energy the AC unit uses to cool the home within 1 hour. A 1.5-ton compressor may cost $500 to $950 per ton to replace, while a 5-ton compressor would cost $300 to $550 per ton. The larger the compressor, the higher the initial replacement cost. Compressor Size and SpeedīTU and tonnage determine an AC compressor’s size. However, the final cost will depend on the size of the system, the type and brand, and the going rate of labor in the community. The cost to replace the compressor in an HVAC system generally runs a national average of $1,200. ![]()
