Jeff Doom installed a gas furnace and air conditioner in our home. He came to our house and assessed the situation, summarized our options, and provided a very competitive bid. Once hired, he secured the necessary permits and reported to the job at the agreed upon time. The project took a couple of days longer than expected due to some issues with a parts supplier that wasn't Jeff's fault; however, this did not present a problem since he worked during the evenings in order to accommodate our schedule. He was polite and professional and kept us informed as to his progress and the status of the work. The equipment was installed neatly, and he cleaned up the worksite thoroughly upon completion. He gave us a demonstration of how the equipment works, instructional guides, and maintenance tips. Jeff was also willing to be flexible with financing the project. JDM Services is highly recommended and I plan to hire them again for additional work.
