I found The Heating Specialist to be absolutely great with their service. I had installed a heating and air conditioning system several years ago and it had some serious engineering issues. Once I contacted The Heating Specialist they were able to figure out those issues and resolve them. This was not a minor task and they really stepped up and did the work to resolve it. I have been using them since. They are due to install a new HVAC system for me in the near future. I trust that will go as smoothly as the fix for the previous system. I do recommend them, they know their business!
