Comments: Five years ago we had a new furnace and an air filter installed. The furnace is working great and the air filter failed just days prior to the 5 year warranty date. Luke ordered a replacement and installed it the very next day at no charge. Courteous and friendly service and he stands behind his work and the products he installs.

Comments: Mr. Luke Nemesh and his assistant called us just before their visit, were very cordial and professional when they came over and started on the work almost immediately. Their quote was very reasonable and when they finished their work, they left the work place in immaculate condition. We would recommend them to anybody who wishes to contract with them.

Comments: Luke was knowledgeable,responsive and came up with less expensive and invasive install. He even fixed a couple of other minor issues without charge. I'll beusing them again for yearly maintenance.

Comments: Luke arrived on time to perform a gas furnace periodic service. His work was thorough, professional, and he was patient with all my questions. He did not pressure me to pay for things I did not need nor did he rush through the job.

Comments: Luke arrived on time to perform a gas furnace periodic service. His work was thorough and professional. He explained his findings without trying to upsell me on unnecessary work.

Comments: This team is great. They answered all my questions. They did several extras for me which i really needed done and even went and got supplies to do an extra repair job of some of the rotten old stuff that needed to be replaced. It looks and feels like the winter will be warmer this year.

Review Date: 05/11/2015 | Author: Ron I.

Comments: Very Prompted and Courteous. He explained everything that was wrong with my system to me and even gave me some great recommendations on how to maintain my system.

Review Date: 04/28/2015 | Author: Dan Y.

Comments: Luke is great!! We had planed to replace and install a new furnace, because another contractor (Bel Red) told me that my furnace is not worth fixing. When Luke came over, instead of giving me a multi-thousand quote for a new furnace he bluntly told me that it can be fixed. And, he did fix it and only costed me a couple of hundreds dollars. Big saving, top quality and really caring his customers. I would definitely recommend Luke and his company to my friends.

Review Date: 02/28/2015 | Author: Ivan M.

Comments: Iim so glad Luke came on time and fixed the furnace, very efficient and reliable. I most defenetly highly recommend him.

Review Date: 02/27/2015 | Author: Joanne H.

Comments: They were here before the time line he said he would be. I appreciate that very much. He told me the estimate first and he went right to it when I approved it. The only thing is that the part that he replaced is now PLASTIC and not cast iron like original.

Comments: Very curtious, professional and affordable

Comments: I was very impressed and happy with Luke. It was late on a Friday when he took my call and was out the next day to bid my job. I'm having a deck built and the gas company I had previously received a bid from wasn't available so I was in a tight spot to coordinate the gas line install before the decking went on. Luke was out the following Tuesday and knocked it out! His price was higher than the other bids I received but his ability to get the job done with little notice, his professionalism, and quality work made it a great value!

Comments: I received a couple bids and selected Heat Flow Mechanical. Luke came when he promised, provided several options to replace my water heater and completed on time. I would definitely recommend them.

Comments: Luke came when he promised to and completed the work in a timely manner. He altered the gas piping and electrical outlet for new gas range so it would fit flush against the wall. Great experience.

Review Date: 04/28/2014 | Author: David D.

Comments: I got several bids to have my heat pump replaced and selected Heat Flow Mechanical because they were the only company willing to work with me to install a quality product on a budget. I could not be happier with the installation and the end product. Luke did a professional job and handled a few curve balls that were thrown his way. The project took him longer then expected through no fault of his own but he got it done. I will use this company in the future for any of my heating needs.

Comments: Went out of their way to make sure I had heat over night before the replacement part could be installed.

Comments: Luke did a great job repairing the leak in my furnace. He was on time and very efficient. I marked him down 1/2 star because when I set up the appointment, he told me he would match the diagnostic fee expense of another company I was going to go with, but when he looked over the job, he said that he couldn't match it because the total repair was less than $200 (which that detail was not discussed when he told me he would match the other company). Overall though, I'm very pleased with the end result.

Comments: Luke was very professional, knowledgeable, and easy to work with. I'm very impressed on how well he was able to educate without trying to "sell" me. Made the whole experience low pressure. He even wore booties when he came inside. Very considerate. I've never reviewed anyone or anything online but was very happy with the service he gave that I feel the need to tell other people! :)

Comments: They did everything I wanted. They were easy to work with. Their pricing was competitive

Review Date: 08/30/2013 | Author: Dorothy H.

Comments: During the consultation, Luke was very knowledgable and courteous. He helped us pick equipment that best suits our needs. During the installation, Luke, Andrew and their preferred electrician did excellent work in a timely manner even after encountering road blocks in our house (it was built in the 50s). I would recommend them to a friend and definitely give them a call if I should need their services in the future.

Review Date: 01/26/2013 | Author: Jeff N.

Comments: My 20 year old furnace went out in the middle of an extended freezing spell January 2013. Heat Flow came to the house to diagnose the problem the same day I called them. Luke provided a repair estimate and 3 options to replace the furnace. He explained each thoroughly with pros / cons. I decided to replace the unit and he returned the next day to complete the job. It was done very professionally. He arrived on time and finished the installation in the time he had estimated. I'd highly recommend Heat Flow to others needing furnace repair or replacement.

Comments: Job is complete. Heat Flow Mechanical did a great job....

Review Date: 06/29/2012 | Author: Pav M.

Comments: Luke from Heat Flow Mechanical, LLC did an outstanding job for us. What is remarkable about him is that he is focused on doing the job right rather 'wrapping' it up. We were adding an additional A/C unit and he went above and beyond to complete extra maintenance items with the furnace that were outside the scope of the project in order to make the A/C install right. His bid was most reasonable and did not haggle for the extra time spent to make the install right. For the customer service and the follow-ups he get a perfect 10 score from me. He is very knowledgeable and would definitely use him again. Thanks, Pav
