I have been using Dean Mechanical Inc. for a while now and I have always been very pleased with them. They came out recently to clean the furnace for routine maintenance. The technicians who come out are always prompt, polite and professional. They arrive on time and get to work right away. If they find any problems they let me know what they have found and give me options of what we can do to fix it. They also take the time to answer my questions. They are respectful of my home and they are courteous. Their pricing is reasonable and I have found them all to be very knowledgeable and friendly. I highly recommend using Dean Mechanical Inc.!
