Don’t just take our word for it—hear what satisfied Hershey area residents have to say about their experience with LCS Heating and Cooling:

Jason and his team did a fabulous job converting my electric furnace to a dual fuel furnace. They did not miss a single detail, and swept and vacuumed upon completion. Jason walked me through what they had done and the operation of my new thermostat. They are absolutely great!!!

I recently was in the hospital getting ready for open heart surgery when my wife, who had stopped home to get things needed for a long hospital stay, called me and told me the water heater was leaking. It was later in the day but I called LCS to see what they might be able to do. They were closed but they texted me back anyway. I explained the situation to them and they were very accomodating. They said they could have a new water heater installed the next day. We made arrangements for our daughter to be there and they did in fact show up and install the water heater the next day. I was also able to wait until I got out of the hospital to pay the bill. These guys are just so nice to deal with. Instead of a headache on top of what I was dealing with I got a solution that took care of my problem. I would highly recommend LCS to anyone. You can't go wrong. They know what they're doing and they are very customer centric and just down to earth friendly people. I can't say enough about them.

What an awesome experience with LCS! Jason, Jon and Patrick replaced my new heat pump within a day. They are all very throughly, neat. They also explained all my concerns or questions patiently. This team is the best!

The best service and fair price. Another company tried to rip me off for almost double the price and Jason. Let me know what the price would be from the beginning with no runaround. He treated me like an intelligent human being and I would recommend them to anybody.

LCS did a fantastic job replacing our old oil furnace and central air HVAC systems. From the first visit I could tell Jason knows his stuff. He explained everything in layman’s terms and made sure I understood what was going to happen. After selecting LCS we were pleased in how quickly they were able to get the job scheduled and completed. Our new Heat pump system is so much better than the old oil system. It’s quiet, efficient, and does not have that smell. Jason, Pat, and John worked well as a team each getting their part done and letting me know along the way how the process was going. I am really happy with our choice to go with Legacy Comfort Systems and you will be too.
