We had our old duct system torn out and Casey replaced it. We had all the insulation had duct system remove due to pest infestation. We had to coordinate with Casey and with the other companies and Casey was very flexible so that we weren’t out of heat for very long. Jim Spencer-Kenwood CA

Went up and beyond my expectations. Super nice guy also.

Very knowledgeable; did a great job.

Casey at Larsen Energy systems is very reliable and helpful. He was able to come out to fix our Greer mini split units heater on a Saturday to accommodate us. Highly recommend his services.

Larsen Energy installed a heat pump on my fire rebuild. Casey was very knowledgeable and did excellent work. I got bids from 3 companies and recommend these guys without hesitation. Competitive pricing and high quality work.

My mother needed work done on her house. He easily accommodated a busy schedule. Was thorough and efficient. Stayed after hours to complete the job. Thank you for all your help!
