Review by Richard, D

My wife and I both have noted how much easier it is to heat our house, and how much more comfortable it is. She also noted that the house feels more ‘solid’ after the work done by Abacus.

Solar Review by R. Rahman

Abacus worked with me from beginning to end to get my solar installation project done on time and budget. Peter has been very responsive to my query and answered any question that came up. Great job guys!

Review by Teresa H.

Peter Tofalvi and Abacus were considerate, reliable and thorough. So glad they were available to work with us and did such a great job. Easy to work with and always great to talk to and answer questions. We highly recommend Abacus for earthquake retrofitting.
