"Jeremy and his team did two jobs for us. HVAC for upstairs and later HVAC for downstairs. His pricing was very competitive to the other quotes we received. The upstairs system kept us at temp through the winter, but starts losing the set temp in the summer. He completed a warranty service which did not resolve the issue. The downstairs unit is two splits in two large rooms. We don?t need them to cool in the summer. In the winter one room is good, the other is incapable of getting to temp if it?s less than 40 outside. From 40 to 55 it requires going on full blast to barely reach 70 inside. I?m a bit shocked at how much electricity these two heats pumps consume in the winter, adding up to $800/month. He specced the system for both floors himself. The downstairs unit was contracted for smart controls, which has not been completed. I am overly patient. Many emails, texts, and calls. Latest job ?completed? in Nov 2024. I don?t believe Jeremy will finish or provide proper warranty support. "

"Amilcar was professional from the start to the finish. He was efficient too. He was very neat and kept the work area clean. I will certainly call on Diamond Plumbing and Heating again should I need service of the type they provide"
