Had this company over twice and the work was OK. Then the company salesperson Marc A arrived and asked all manner of inappropriate personal questions. He repeatedly asked me if I were married and repeatedly asked me about the ethnic origins of my last name. An independent third party who overheard the questions could not believe what was going on. The most invasive and privacy-violating sales presentation ever. Unacceptable! My advice to anyone who has this "salesperson" is to audiorecord and post it for all of the world to hear. On top of it all, the "salesperson" could not answer the one question I asked about furnaces air conditioners while he was busy interrogating me about matters totally unrelated to furnaces and air conditioners. I have since had two other contractors who actually talked to me about furnaces and air conditioners which was very refreshing plus I now see that the company "salesperson" has very little, if any, technical knowledge hence the need to create inappropriate and unacceptable distractions.
