We just got our mini split A/C system installed by LCS. Jason was wonderful to work with - so responsive, professional, and knowledgeable. He did a great job installing the indoor and outdoor units on our very old house! Highly recommend Jason and LCS.

Great experience with LCS. Jason came out and explained the benefits up upgrading to Mitsubishi unit as well as the up front costs. They got the work done quickly. We've already noticed the temp is more steady and comfortable. Looking forward to seeing how savings stack up on our first bill next month. Strongly reccommend.

Google verified job · Great service! The tech was on time and ran further diagnostics once our problem was resolved to ensure everything was in good shape. The price was more than reasonable and same day part installation. I would definitely recommend them after having multiple other service providers in the area also service our system

Legacy Comfort Systems did a great job setting my folks up in their new home. Jason addressed all of my parents' concerns, fixed what needed fixing, and educated them about their system. He made them feel safe and comfortable, and they are super happy with the hot water that they now have. He was also incredibly kind and patient with them. Thanks, Jason!!

Jason at LCS was very knowledgeable and extremely detail oriented when installing our new mini splits in our old farmhouse. Everything looks incredibly clean and we have cut our heating bill in half. Can’t say enough good things about LCS!
