Dependable and professional. Extremely happy with the work!
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 company! We had some kinks to work out between our old house and new system. This is a company that cares!
LCS has been great! The communication on all levels has been excellent. The technician, Sam P. was wonderful- great communication, very personable, explained things great!
It was time for a check up on my air conditioning. I carry the yearly maintenance. The technician that came out was actually a woman which is absolutely awesome. She Did a great job.
Great communicators Always on time Strong product knowledge Sam was customer focused, efficient and thorough
Technician was very knowledgeable and very professional… He was very respectful of the interior of the house by wearing his booties… And we went ahead and scheduled our next two check ups for the furnace this fall and AC for next spring of 2027
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…
Update for 22 July, 2026: Hector and Christian did our seasonal cooling system maintenance. They did a wonderful job. They walked us through the status of the system, and what they found that needed work clearly and knowledgeably. They were super friendly, too. It’s clear they care about the work that they do…
LCS has an amazing team! They are always up in the latest technology for you ultimate home comfort. Communication from the office to the field is the best I’ve ever encountered, keep up the great work.
The technician was on time, friendly and efficient. She explained everything that I needed to do for future maintenance, which was super helpful!

Hector came out and was professional and fantastic to work with! He answered questions and handled everything just great!
LOVE LCS! An incredible company who provides an exceptional customer experience! Professional technicians who are timely and take pride in their work! TJ showed up on time, was thorough, professional & genuinely kind! Thank you for continuing to provide exceptional service!
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…
We've used LCS for 15+ years and have appreciated their service. We subscribe to their twice annual tune ups, and have never had any issues. Highly recommend them!
The LCS Team are always professional from scheduling the appointment to completing the work. We’ve used LCS for 5 years and they always provide great service!!
Our tech that came out, Hector Castillo, was fantastic! Extremely accommodating and explained everything to us before, during, and after the maintenance visit. Highly recommend!
Sam did a great job and explained everything. No pressure, just helpful! Thank you. I renewed my service and couldn’t be happier with my experience. The ladies did a great job and explained everything. Thanks again
I received training from the LCS owners Renee and Travis. They provided exceptional instruction, and real-world stories that directly apply to running a better business, especially when it comes to furnace repair and heating system replacement. They took time to answer questions and share insights. I left feeling…
We have used other companies in the past that have sold us things we didn't need. LCS is very honest and they do a great Job of explaining any problems as well as the work required to fix it, without talking over your head.
Always a great experience with LCS!!
Sam did our tune up today and was great! Nikita helped us out 2 weeks ago and was stellar as well!
Nothing but wonderful, personalized, professional service for many years.
Just had TJ out to make sure we’re ready for the winter. Been using LCS for five years now and I’m very happy with the techs that take care of me and the friendly phone staff there.
We have had such a wonderful experience with LCS! We purchased our unit last year and just had our first service done. We've been nothing but thrilled by the customer service and equipment. Today our technician Hector was incredibly knowledgeable and so very kind! Great start to our day 🙌🏽
LCS tech was on time, efficient, courteous and knowledgeable.
AC unit went out on a 83 degree plus day. LCS was out in the morning with standby units and repairs to be done within 48 hours on complete replacement unit! Great response and professional service!
Technician, Jerome, was professional, helpful, reliable, and friendly.
We were behind on maintenance so Sam did both today and found some minor issues that needed addressed. He fixed everything and did a great job! Highly recommend Sam and LCS.
Nikita was very thorough and great to work with! We’ve been very happy with LCS
As always showed up as promised and on time. Super professional and explain things thoroughly. Very happy with the service they have provided me over the years.
T'Shayla did a great job! She explained everything she was doing.
Called LCS HVAC for a long over due check up and tune up. Work was completed satisfactory and on time, giving me much needed peace of mind. Thanks LCS!!
My experience with LCS was fantastic. They were punctual, professional and knowledgeable, not to mention reasonable.
Purchased HVAC system 11 years ago. We have two tune-ups every year. No issues in that time. Very nice and knowledgeable technicians and customer service.
Technician Nikita was friendly and knowledgeable...very quality service oriented!
Sam did a very thorough job on my A/c checkup! Also he was extremely personable and knowledgeable about the system, and I'm sure I will request him for future hvac needs.
My technician, Sam, was very personable and knowledgeable. I would definitely recommend him and LCS.
Was able to come out next business day.
We have used LCS for years and have always been treated fairly. Over the years they’ve installed a new HVAC system, timely serviced the very few problems we’ve had, and are just good people. We have recommended LCS to many people and would recommend them to you too.
LCS has provided excellent service/maintenance for both our AC/Heating units for years. Always professional, knowledgeable, and friendly. Mark, especially, has been a technician I can always count on for his years of service experience. Highly recommend LCS for all your heating/cooling needs.
LCS replaced my HVAC and do regular maintenance. The pricing was competitive and their work was stellar. Would absolutely hire again!
I went with LCS Heating and Cooling and I couldn’t be happier. They sent someone the day after I called (they offered to send the emergency technician immediately but I didn’t want to make someone come out on Memorial Day), Travis was able to identify the issue and fix it immediately for way less cost than I…
Great service. Have been a customer for years and always extremely impressed and pleased.
always a good job, explain things well. Timely.
Absolute professionals in every way.
Updating Jan 2025: The entire recommendation below still stands. I genuinely wish I had an LCS for every type of service my home uses. Original: Incredible service! I've used LCS for years (through two houses) and there is no one else I trust more to service my a/c and furnace. The front office staff is responsive,…
Always kind and respectful.
Our furnace died and we needed a new one. LCS helped us in the past with other work and did a great job. We went back to them and could not be happier. Super friendly and helpful and great attention to detail. Highly recommended using them. We just used them again and did another great job! Brandon and his crew…
They've always been professional, same tech for years! Good work at a fair value!!! Nikita was, again, professional and friendly!
Great response time. Would have given them 5 stars but they never followed up a quote to fix what is causing issues with our system.
Mark is the best! Always reliable and knowledgeable. Highly recommended.
Great Service! Everyone we were in contact with; Nikita ,Jeff & Luis were very knowledgeable and friendly
Always courteous and professional technicians. They always do a fantastic job and make sure that you're totally happy before they leave. I would recommend them and have recommended them to everybody that I talk to.
Excellent customer support! Technicians are very friendly and professional . Mark H and Mike were awesome! They went above and beyond.
Always a great experience. Proactive, prompt, and friendly. Always feel like they are doing what’s needed and not just trying to sell additional parts and services.
Always on time, professional, and trustworthy.
Jason and Gary were awesome! Efficient and knowledgeable
Friendly, knowledgeable & I've never had any issues.
Always a pleasure to work with and very professional. Have been using them since 2018 and still happy with their work. Thanks LCS!

I recommend LCS to anyone who needs HVAC services. They offer great customer service, are reliable, efficient and honest.
Always a good experience with LCS. On time, pleasant, and no what you’re getting.
LCS honored weekday pricing when their schedule was too full to come out for my service. Nikita came out on Saturday morning to get my AC running in tip top shape. I am never sold products I don’t need. The technicians - especially Nikita-are very thorough and professional! Thank you LCS! See you again in the…
We have used a few other HVAC companies in the past, but once we tried LCS we knew we'd found the best! Always very professional and the techs explain every step of what they are doing. Previous services discovered a problem other companies missed, and this time was just as great. Our tech, Logan, noticed the amount…
