We were very pleased with LSM when we needed to replace our furnace. The problem occurred late in the afternoon on a Friday and the after hours tech was there within an hour and diagnosed the problem. He said he would check my options and report back on Monday which he did. We elected to replace versus repair and they were ready to install within days with the details handled by Tina. The installers were very professional and careful when doing the installation of the furnace. I needed some final adjustments and tuning of the new unit and one call to Greg and he sent John over to make the required fine tuning. He was very knowledgeable and informative of the new unit. I have dealt with LSM in the past and would highly recommend them for your heating and cooling needs.
