"Sales rep measured rooms and windows to perform a load cal'n. Proposed a quality Carrier system at a reasonable price. The installation took a little longer than expected due to use of an inexperienced helper, but eventually it appeared to be a quality installation. They met my requests for minor modifications/enhancements to allow easier maintenance. Workers wore masks at all times, used drop cloths along walking paths and shoe covers, so the job was kept clean. Took time to explain system, installation and maintenance points. Were honest about risk of condensate pipe freeze-up and potential remedies, and "orphaned" water heater. Overall, quite satisfied with the equipment and installation. Awaiting finalization of punch list paperwork items."

"The employees were all informative, answered all my questions and were able to install a new A/C unit the next day. They were on time for both the check and the install. They were respectful and completed the install earlier than expected. I would highly recommend Rohrerâ s!"
