This is my 3rd time using Cosmopolitan. In 2009 they installed a new furnace, tankless water heater and A/C in my old house. In 2015 they repaired and eventually replaced the A/C in my current house. This March they replaced my furnace and water heater. Ejaz from sales was very knowledgeable and was able to answer all my questions. He was very responsive and provided appropriate solutions based on my house size. Fred completed the latest furnace and water heater install. He did an amazing job routing the furnace pipes and ensured everything was working properly upon completion.
