CPR Mechanical Guarantees

Performance Guarantee

CPR Mechanical guarantees that when the equipment we have installed is maintained and operated in accordance with the manufacturer's operating and maintenance manuals, the system will perform as we have stated and agreed upon. This guarantee is meant to guarantee that the equipment we install is sized accurately for the home at the time of installation. It does not cover situations where the home does not maintain proper temperature caused by a component or part failure.

Satisfaction Guarantee

CPR Mechanical's installation technicians are the best in skill, attitude and workmanship. They will care for your home and complete the job with speed and precision. They will not wear shoes on your carpets. They will clean up when they are finished and take personal responsibility for your satisfaction. They will not smoke or swear in your home and they are drug-free. If, when they have finished in your home, they have not performed in accordance with these high standards, we won't consider the job done until you are satisfied with the results.
