See What Our Clients Have to Say

  • We have lived near the beach for 25 years with central heat, but no a/c. With the number of uncomfortable hot days increasing every year, we finally decided to add a/c. We considered adding a/c to our existing duct system as well as a new ductless system. We got three bids from contractors recommended by YELP. We chose Liberty Mechanical and are very pleased with the result. The owner, Jake, provided the clearest explanation of our options and the lowest price for the Mitsubishi ductless system we selected. His team, which he supervised, installed the system on time, on budget, and accommodated our schedule constraints. The crew were professional, courteous, and respectful of our home. They system works great. From Loni, the office manager, to Jake and his crew, we highly recommend Liberty Mechanical. Ann

  • Simply the best at what they do. Professional, courteous, respectful and hard working! Would HIGHLY recommend to anyone who needs AC and or Furnace installation or service. No other words to describe the field and office team...Loni, Cory and Randy are the BEST! Luna

  • I was referred to Liberty Mechanical from a friend who recently added an extension to their home. They said the company did solid work and had competitive prices. I had 5 different bids on my home already before contacting Liberty Mechanical, and I ended up selecting them due to the quick responsiveness and great pricing. The process began with Loni in the office who was outstanding throughout it all. She is very friendly and very communicative. Jake came out to bid my home, and he was very thorough and described the job well to me. Randy & Cory were the installers and they showed up on time and were very respectful of my home throughout the 2 1/2 day install. Their installation was only slowed by about a 1/2 day due to steady rain one day, which made the electrical part of the job a tricky one. I had a 1,300 square foot home built in 1947 that only had a floor furnace. Liberty Mechanical installed a new furnace in the attic space, ran all the duct work to 8 different registers they cut throughout, and installed an A/C unit along the side of my home. My new forced air system is amazing and extremely quiet. I highly recommend Liberty Mechanical. Eric

  • Jake and his team at Liberty Mechanical are great!! After my recent tuneup my air conditioner is working fabulous and is quieter too! Jake set me up for a maintenance plan which will help keep it operating efficiently all year long! And the best part is I don't have to keep track of when I need to follow up, they do it all for you! Thanks Jake and Liberty Mechanical for making my life easier and more comfortable in the heat! Stephanie

  • These people are pros! Their customer service is best. Their attention to details is the best. Their work ethic is the best. I worked with Loni , Jake, Chris, and Ryan and am delighted with them all. Everyone was a pleasure to work with and they did an excellent job. I can recommend them without any hesitations. Diane

  • We have had central heating and air conditioning installed by Liberty Mechanical in in three houses. Their work is excellent and the prices are great. The staff are professional and friendly and the owner, Jake, follows up to make sure all of the work is done correctly. They are fast and neat. George

  • Jake and team have been servicing my real estate clients for over 10 years. He brings terrific knowledge, value and the ability to communicate well. Haven't seen a project he couldn't solve yet. I'm so grateful to have him on my vendor team. Julie

  • The Team from Liberty Mechanical did a fantastic job on the replacement of our 30 year old furnace and AC. They were on time to every appointment, clean, and cared about the quality of their work and the final product. They treated my house like it was theirs. Great job! Paul

  • Jake and his team were exceptional. They removed and replaced our old duct with new R-8 duct work, upgraded our old registers and installed a whole house fan that we purchased directly from another source. Their pricing was fair and their service was excellent. I really appreciated Jake's knowledge and attention to detail. When he came out to quote the project he thoroughly reviewed our existing system and found some additional flaws that weren't point out by other bidders. He included these other repairs in the scope of work. Going with the absolute lowest price is not always the best value. I value quality service at a reasonable price and would not hesitate to use Liberty again or recommend them to anyone looking for a great Hvac contractor. BTW, they initially indicated the job would take a day and a half, but got it done in one day which was a real plus for us. Craig
