I had Abacus Plumbing, Air Conditioning & Electrical out to just to do a plumbing inspection and to service my AC. In my opinion they were great, they were on time, I got a phone call saying they were on the way, they were very professional with what they did they were very knowledgeable in both areas. They also didn't make recommendations that weren't necessary, so they didn't try to sell me on anything I didn't need. I would recommend them.
