On a quarterly basis, we evaluate the future deployment of our idle fleet assets under current market conditions.
For the three and six months ended June 30, 2025, we retired four and 21 compression units representing approximately 5,900 and 16,100 of aggregate horsepower, respectively, that previously were used to provide compression services in our business. As a result, we recorded an impairment of compression equipment of $3.0 million and $6.8 million for the three and six months ended June 30, 2025, respectively.
For the three and six months ended June 30, 2024, we retired two compression units representing approximately 1,300 of aggregate horsepower that previously were used to provide compression services in our business. As a result, we recorded an impairment of compression equipment of $0.3 million for the three and six months ended June 30, 2024.
The primary circumstances supporting these impairments were: (i) unmarketability of certain compression units into the foreseeable future, (ii) excessive maintenance costs associated with certain fleet assets, and (iii) prohibitive retrofitting costs that likely would prevent certain compression units from securing customer acceptance. These compression units were written down to their estimated salvage values, if any.
