Dependable and professional. Extremely happy with the work!
Jerome was knowledgeable, courteous and professional.
Great, knowledgeable team to help anyway they can! Hector came for the annual furnace check up. Did all the tests to make sure everything was working properly and even talked me through some things to look for early signs of something was wrong. Which I really appreciate and think is interesting to know. Thank you!
The ac technician was very efficient, friendly and did not try to sell me anything. I will use LCS again.
We had LCS service our furnace for the winter and couldn’t be more pleased with their services provided by their Technician Ryan. He was very professional and offered several helpful tips. We highly recommend them John Powell Carmel IN
Sam was great. Did a very thorough job and explained everything well. Even had pictures
Nikita was amazing! She came to our appointment on time, came back with a part we needed same day, and stayed late! She explained everything and was very personable! Give her a raise!
Nikita is an expert tech. Answered all our questions during the service inspection on October 19, 2026.
Nikita came out to do the furnace inspection today with Brayton. They both did an excellent and thorough job. Nikita explained things thoroughly to me and gave me some very valuable tips to keep the HVAC system running efficiently. I can highly recommend LCS and these two incredible technicians!! Thank you.
I have been using LCS for years! It is a family owned company that truly invests in their technicians. I have never felt like the suggestions their technicians made weren’t necessary. They are the only HVAC company that I have truly trusted. The technicians that have serviced my homes have been pretty consistent…
Great service. The technician did a thorough job and the price was reasonable. They even submitted a request for me to receive a rebate for the air-conditioning service. Great company. Would highly recommend.
Great company! We had some kinks to work out between our old house and new system. This is a company that cares!
The technician was on time, courteous, and efficient.
Great experience
Sam’s darn good.
9/25/26. Nikita from LCS, was my service tech for maintenance on my hvac. She did a greatjob, was very nice and very efficient. Very happy with her work.
Excellent and immediate service. The Technician was incredibly knowledgeable and informative for my needed service.
The 20 year old water heater failed and LCS replaced it and the bad gate valves with better ball valves.
This was my first time using LCS and I was very satisfied of the services performed. The technician was courteous and professional and had knowledge of my unit. He took time to check everything to make sure my unit was functioning the way it should be. From scheduling to services performed, I am very satisfied. I will definitely use LCS again. Thank you

Prompt, professional, knowledgeable service.
After getting several quotes around downtown Indy area for a full furnace and AC replacement, I ended up landing on LCS for a number of reasons. Everybody was a pleasure to work with from the top down - especially appreciate O’Neil who originally came out, and then Mariano and Felipe from the install crew. Pricing…
Technician was friendly, helpful and knowledgeable. I will definitely ask for him again.
Fast service. Made it easy
Staff is great. Techs are knowledgeable, straight forward and have great communications. When it was time to replace our HVAC system, Travis was great. Took the time to listen to our concerns, explain everything and then let us make the decisions. I want to say that his advice was spot on. Maybe a little…
Jerome did a good job fixing my a/c. Very professional.
Hector from LCS performed preventative maintenance on our Daikin unit. Hector was thorough and efficient. He communicated throughout the process and provided a summary at the end of the service call. Through out the years we’ve worked with LCS, they have always provided high quality and superior service. Highly recommend.

Great job as always. Such nice employees. So glad we found your company!
Thorough service. All issues explained in detail. Friendly, courteous and skilled staff.
I’m a customer with a service contract with these guys - they frequently call and reschedule, slow to answer after hours calls (through a service) and don’t have parts (eg filters) when they do show up to service equipment THEY INSTALLED!!! What am I missing. Useless.
My first routine maintenance from this team, Sam was professional, courteous and knowledgeable. Pleasure to do business with this team
Everything was great. We bought another year. They are very professional. The service was excellent. I highly recommend them.
Jose provided the LCS 7 STAR service today! I have been fighting humidity in the house and he listened to my concerns. Then did the scheduled maintenance and took the time to go thru the thermostat settings with me. I thought that I had been over ridding the system settings and I wasn’t. I also thought I was helping…
Sam was friendly and efficient!
T'Shayla did a Great Job. She was very Professional & Knowledgeable. She quickly identified the issue,cand let me know the cost. The House was cool again in no time. I highly recommend LCS & T'Shayla!
Mark was our technician and he did a super job on his visit to our home for AC maintenance. Not only was he prompt and professional, he detected that we didn’t have the proper fuse for our unit. He didn’t have what we needed with him, so he returned by the end of the week to complete the installation. We continue…
Great service, as usual!
The technician came out to see if they could repair duct work for our dryer. She went above and beyond in assessing the issue. She also cleaned the lent in the wall.
As a first time homeowner, I am so grateful for Nikita’s kindness, patience and expertise. She went above and beyond to help me understand my heating and air conditioning system. “Highly recommended!”
From proposal to installation, LCS provided a high level of service, timeliness and disclosure and at a fair price. I used them for service on my old HVAC system and when I moved, they followed me across town to continue our relationship at our new home. So, when I was ready to replace the existing system, my…
TJ was very good. Prompt and polite. She knew what she was doing. I had concerns about insulation that our handy man wrapped around a pipe to furnace. She quickly recognized it wasn’t code and ask me if it was ok to remove.
11/24 -Furnace. Once again, Nakita came for our furnace tune-up. She is always upbeat and friendly. She got straight to it and everything checked out fine. Thanks for being a great local choice! 4/25 -Cooling UPDATE: Technician T’Shayla sent a note that she was on her way and showed up at the scheduled time. She…
Hector serviced our system today. He always did an excellent job, was pleasant, and communicated very well. He gave great feedback on his observations. We are happy with the outcome.
Kelly was very professional and courteous technician. Felt very comfortable that the work was done correctly. Kelly explained what was done and things I should watch for in the future. Job well done!

Excellent service Very pleasant and professional person.
LCS installed an energy efficient HVAC system in March 2023. When I had an issue with the AC, they sent Nikita out to service my system. I have never had such good customer service and a technician as knowledgeable and communicative as Nikita. I received a follow up call to make sure my system was in working…
Sam was awesome! On time and very respectful. He thoroughly cleaned both our furnace and A/C and they’ve not run smoother. He told us about their membership program and WHAT A DEAL! For the cost of a lunch combo per month, we get a dedicated team to keep our system sharp and on the double when emergencies happen.…
Hector came out and was professional and fantastic to work with! He answered questions and handled everything just great!
These guys are really good! I’ve used them on multiple projects and they are always super professional, clean installs, and get the job done quick.
Sam was great! He was on-time and got things fixed quickly.
Mike with LCS did a great job with the installation of our new heat pump. Good communication on what he was doing throughout the day. Clean up and reorganized the area at completion. Meet all expectations.
This company is top notch. Very professional, very communicative, honest, reasonably priced, and is paperless which I really like. Very kind staff when I call. Great customer service. I had Hector today and he was great. I would highly recommend.
Their technicians are informative, friendly, and efficient!
Excellent service and knowledge of HVAC!
We had LCS Heating and Cooling come out to fix some major issues with our HVAC system, and they ended up doing a pretty significant amount of rework to get everything right. The original installation had the unit set up in a way that made it nearly impossible to service, so their team actually flipped the system and…
Excellent people and company! Their technicians are knowledge, their pricing fair, and their customer service top-notch!
Technician was out for routine furnace maintenance. As is always the case with LCS employees, he was friendly, knowledgeable, respectful of our home, and explained what he was doing. I always learn something new about our system from them. Prices and different plans were also explained so we could make the best…
They were helpful and compassionate. Despite some issue due to a break during inspection, they worked hard in fixing the problem and also helped with a problem unrelated to their service. I would recommend.
Extremely informative and friendly!
As many people probably experience in the winter, our electric bill at our home was over double what it typically is. My thought process was “ehh it’s winter, it will do back down.” My fiancé however thinks very differently than I do. She checked our thermostat and found that our emergency/auxiliary heat was…
LCS has always done good work for us and have beaten competitors on work we’ve done with them. Sam spent extra time with us outside typical maintenance protocol to help us with checking for growth or moisture concerns as we have recently dealt with a leaking shower that created mold spores. Update: Had a bathroom…
I’ve been using LCS for many years. I’ve come to know many of the people who work on the equipment. Great people. If you haven’t used LCS before you must give them a try.
I couldn’t be happier with the service we’ve received over the years from LCS. Everyone is always prompt, polite and very efficient. Very happy to be a customer of theirs!
The service tech, Sam, was fantastic. He explained everything that he was looking to check on the furnace and took the time to make sure that I understood his findings at the end. He was knowledgeable, friendly, and courteous during the visit. After several bad HVAC experiences, it was encouraging to have a positive one with the LCS team.
Jason was very pleasant and did a good job on the maintenance and repair. I would recommend your services.
Sam was very friendly and explained possible issues to keep an eye out for with my furnace. I appreciated his thoroughness!

LCS always does a great job of communicating regarding appointments and are always on time. Kelly came out today to do our routine maintenance plan, found an a small issue, and was able to get us taken care right away under warranty. Kelly was very professional and super nice. I’m hoping to request her every time!
We've used LCS for years for our HVAC service. Always get a text when they're coming, with a picture of the technician. We recently needed to replace our furnace, so we did a new AC unit too (was the same age). The staff explained all our options very carefully and even helped with the financing! It was an…
Always friendly, considerate, on time service technicians. I mean, ON TIME! The office staff is also very friendly and helpful. Highly recommend this company.
We love LCS. We found them when we moved into our first home and needed a new furnace installed 3 years ago and they have been nothing but fantastic since. They are never late, always communicate well, and are nothing but pleasant. 100% recommend working with LCS and we plan to be long term customers
Sam from LCS came out, and quickly and efficiently diagnosed the main issue with my system. He walked me through everything, and got right into resolving the issue. Had an noticeable difference in my system immediately. Sam is a great, professional, and thorough guy. LCS is my new go to heating and cooling company.…
We’ve been using LCS for many years. Every time they come out they are professional and efficient. Their pricing is affordable and the work is quality. We are part of the service plan, so today’s trip cost $0.00
Knowledgeable and took reasonable time to complete
I've had LCS maintain my heating and cooling equipment since I've lived in my current house (14 years!). They've always done a great job, been timely, reasonable, and recommend only needed changes/repairs. I really appreciate knowing things are done right every time.
LCS is probably the best HVAC company in Indianapolis. I have found that they are responsive to my needs and keep me posted on their arrival time. Their technicians are knowledgeable and explain what is going on with my system in a way that I can understand. Excellent service!
This is my first time using LCS. My technician, Nikita Jenkins, was extremely personable, professional and knowledgeable. She’s pretty much diagnosed the problem in just a few minutes and then confirmed with her diagnostic equipment. I signed up for the maintenance plan and I’m looking forward to great, friendly, and professional service for years to come.
Absolutely fantastic experience with LCS Heating & Cooling! Kelly was amazing, friendly, professional, and knowledgeable. She explained everything clearly and made the entire process smooth and stress free. You can tell she truly cares about providing top-notch service. Highly recommend LCS, and definitely Kelly!

Semi-annual planned maintenance. As always LCS did a fantastic job. Great job by the technician T’Shayla Jones! She was thorough, efficient an pleasant to work with.
Sam was friendly, professional, and knowledgeable. We felt like he really listened to what we had going on, and was able to explain how he needed to troubleshoot the issue. We were very impressed that he was able to come out the same day, especially when the weather was so terrible and our furnace was out.
Nikita was very good at what she does. Found the problem and fixed it. Very professional and Very informative on what the problem was and on the work she was doing. Very pleased Thank you Nikita and LCS for your services.
Sam was outstanding. Between the level of professionalism, detailed insights, recommendations, and focus on balancing cost to return on investment, he was the epitome of service excellence. If the balance of their organization is even 1/2 as professional as Sam, I’ve found the HVAC team I’ll be turning to for years…
