I think integrity and honesty is one of the most important attributes I look for when looking for someone to do work in my home. I need to trust what the specialist is telling me and that they will fulfill their promises they give when they are first trying to get your business. Mark London has displayed integrity, honesty and an obvious knowledge of what is needed. He gave us an estimate and kept within the estimate he gave. His workmanship was excellent and he has followed up with us to make sure everything was working correctly. I would highly recommend London Mechanical!

I highly recommend London Mechanical. He came out within a few hours of me contacting him about my broken furnace and had it fixed very quickly and economically. He was very knowledgeable about fixing some of the strange duct work I have in my older home and adding a future A/C unit as well as the costs of replacing my 30 year old furnace soon. Very happy that I found someone local, dependable and affordable!
