No complaints whatsoever.
Description of Work: Jim McDonnell bid on a boiler/heat install at my home. He is thorough, professional and punctual. He answered all of my questions quickly and precisely. He even went as far as to discuss his plans for the new system with a relative of mine that is also in the business. Jim's design skills are precise and there is little if anything he does not catch during the planning process. The only reason I did not work with Jim was that he was out-bid by another fully qualified bidder. I definitely would recommend his services to anyone.
