    Do not recommend unless you want to pay top dollar for bottom barrel install. We moved into a home…read morewith a Shaw's 2016 heat pump install and will be spending ~5k to address the poor quality of the air handler install. The previous owners of my home were quoted 13k for this install. Code violations, did not follow manufacturer's instructions and no permits pulled. Permits have been required for changeouts in Talbot County since 2012. Shaws declined to view the install and consider making things right. Another local HVAC company saw this install and said "holy shit I wouldn't have put a sticker on this." - Our unit is only ~ 1 inch above grade and is supported by patio pavers. Both unit, ductwork and condensate pump are sinking into mud causing moisture and mildew problems. - Manager said he has never heard of codes requiring mechanical equipment to be at least 3 inches above grade. Attached is a screenshot of the 2018 international mechanical code (current building code for town of Easton, MD) regulation for clearances above grade. - Manufacturer's instructions included 4 inch condensate p trap, due to unit being installed only 1 inch above grade they installed a shallow trap (~ 1 inch) which manual says explicitly not to do. Picture attached. - No permits pulled. I believe that the unit would not have passed an inspection. - Duct work is touching dirt. - A crawlspace company that had no skin in this game noted our install is "in the bottom 10% of installs they've EVER seen in this area." - Our condensate pump was buried in mud despite unit saying "Indoor Only". Shaw's manager said that our crawlspace should be considered indoor, but at the same time also said that there was no secondary condensate system because it was not considered an indoor environment. Be prepared to get the angle that least benefits you if you use this company. - No secondary condensate drainage, secondary pan or no overflow detector which goes against manufacturers recommendations. The real kicker in this situation is that Shaw's refused to come out and view this install and to consider making the situation right. There was one other company that we had questions for after we moved in and they came out, assessed the situation and made it right. I would not recommend an expensive install with this company.

    This company did a GREAT job replacing my boiler that had failed. They responded promptly, worked…read moretirelessly, and resolved a few performance issues that arose during the installation, and the owner was directly involved from start to finish. Cannot recommend them more highly!
