Customers frequently highlight punctual arrival, clear communication of options, and fair pricing for furnace and AC repairs or installations. Recurring themes include professional conduct, efficient service, and helpful explanations of system performance. One critical review notes a missed coolant leak diagnosis and unhelpful customer support when the issue persisted, citing a lack of service warranty.

Once again, Larry's Heating and Cooling came through from the initial service calls with Brody, to meeting with Tom the Project Manager, to installers Nick and Collin and also the office manager...they are quick to respond, call to give a heads up they are on the way, explain the options, and fix the problem! This time it ended up being a new furnace at my son's house. Professional, polite, respectful and personable. Thank you once again!

I had them out for AC repair in the spring. They told me I was low on coolant. I asked if they had checked for leaks and they assured me they had. 60 days later..... no coolant again. When I called, they were super unhelpful and offered no kind of warranty on their services. Kalin's came right out and found a large leak that nobody who checked could have missed. If I could leave zero stars, I would.

Wow...I don't live in Vermillion but as a realtor, I needed someone to check in on a gas leak for my sellers. They responded quickly, and took care of my clients. Will definitely recommend them to my future clients and friends that live in or around Vermillion.

My furnace wouldn't turn on. The company that installed my furnace charges $180 for a service call on top of whatever the cost of the problem is. I called around for a more reasonable price. Larry's Heating charged only $60 for a service call and the technician arrived within minutes. Larry's service tech Matt checked to make sure my furnace was running properly. It turned out to be a broken thermostat. Matt installed a new thermostat in minutes and we had a fun conversation all the while. I highly recommend Larry's Heating and Cooling and they are my go-to company now. : )

We have been a Larry's customer since 2007. They have done numerous repairs, leak finding missions, and general check-ups of our AC and furnace. When it came time to replace our HVAC system this year, we didn't even look at other companies. Larry's has always treated us fairly, explained things in terms we can understand, and been available during times of crisis when the heat went out in the dead of winter. They are punctual, friendly, clean up their workspace, and willing to accommodate requests that are specific to our home/family. We will continue to be a loyal Larry's customer. Even though we hope not to need a repair for a LONG time, we know we can count on them if we need anything.
Positive: Quality

We recently did new HVAC project with Larry's and I would highly recommend them. They were especially good at communicating project details, timeline, and options. They also did a great job working around the oddities of our old system. Heating bills went down drastically. Thanks for all of the work!

I have the comfort care program for my heating and cooling. Roger the technician showed up on time for my appointment. He was very polite and explained everything he was doing and how my furnace should perform. It is nice to have the peace of mind knowing my furnace is ready for winter. I highly recommend Larry’s Heating and Cooling.
