They accommodated our toddler’s antics at the same time! We are grateful for their hard work and professionalism. They explain things well and put their customers first. You can’t go wrong with LCS!Posted on Google Vanessa BatzelTrustindex verifies that the original source of the review is Google. We had a fantastic experience with Legacy Comfort Systems installing our mini splits. Jason was incredibly responsive, answered all of our questions thoroughly, and followed through on everything he promised. Patrick and Johnny handled the installation and were punctual, professional, and very considerate—especially with keeping noise levels down while I was on work calls. Patrick also took the time to walk us through how to use the mini splits, which we really appreciated. The pricing was very reasonable in comparison to other quotes we received. I would highly recommend Legacy Comfort Systems.Posted on Google James WeilerTrustindex verifies that the original source of the review is Google. Legacy Comfort Systems was a pleasure to work with. Jason was very knowledgeable and listened to what I wanted in a HVAC system. He took the time to make sure that I was getting a properly sized unit. The system was reasonably priced compared to other units of the same features. After installation of the system Jason went over the system with me, especially the smart thermostat. The job was done professionally and was cleaned up after. I was provided with spare air filters and humidifier pads. Jason was quick and efficient in getting me the paperwork needed for the energy rebates. I would highly recommend using Legacy Comfort Systems for any needed HVAC work. Update: In February I noticed some water on the basement floor coming from the HVAC unit. I emailed Jason on a Sunday and shortly received a reply from him. I was told to shut off the Humdifier unit. This stopped the water issue. Since the heat was working I talked to Jason about coming out on Tuesday. Jason fixed the problem by putting a trap in the Humidifiers drain line. This prevented air and water from being drawn back into the Air Handler when the variable blower motor went into high speed. As an extra precaution Jason added a water sensor that would shut down the Humidifier if water was to get on the basement floor. This was all done at no charge.Posted on Google Andrew LuderitzTrustindex verifies that the original source of the review is Google. Highly recommend LCS! During our initial estimate, Jason was forthcoming, respectful, and knowledgeable. We are pleased with the finished product and would certainly use LCS again for our heating and cooling needs.Posted on Google Jonathan RogalskiTrustindex verifies that the original source of the review is Google. Legacy Comfort Systems recently installed a new heat pump in my attic to replace my old system and I couldn’t be happier with how everything turned out. Jason and his team were friendly, professional, and clearly knew what they were doing. They repaired some damaged duct work, set up multiple zones so the temperature stays even throughout the house, and made sure everything was running perfectly before they left. The difference in comfort and efficiency is night and day compared to my old setup. I also really appreciated how they helped me apply for rebates — they handled the details and made the whole process simple and stress-free. It’s rare to find a company that’s this responsive and takes so much pride in their work. I highly recommend Legacy Comfort Systems to anyone needing HVAC replacement or upgrades.Posted on Google Denise TiffanyTrustindex verifies that the original source of the review is Google. Working with Jason and Patrick from Legacy Comfort Systems for our Mitsubishi mini-split installation was truly a remarkable experience. From start to finish, their professionalism and expertise shone through. The pricing they offered was very competitive compared to other companies we considered, but it was their exceptional customer service that really set them apart. Jason came to our home to assess our needs and provided a thorough explanation of the pricing and what to expect. His attention to detail gave us confidence in our decision. The team was punctual and completed the installation within the promised timeframe, which we greatly appreciated. Patrick walked us through the system’s operation from start to finish, ensuring we understood everything we needed to know. Overall, Legacy Comfort Systems has proven to be the best HVAC company I have ever worked with. I highly recommend them to anyone looking for reliable and top-notch service!Posted on Google Lorraine StittTrustindex verifies that the original source of the review is Google. Wonderful experience having a house wide mini split installation done by Jason and his crew at Legacy Comfort Systems. From our initial meeting where Jason explained our options in great detail; to the multiple day installation process; to educating us on our new system, everyone involved was a true professional.. always pleasant, knowledgeable and showing great attention to detail. We couldn’t be more thrilled with our system and secure in our decision to go with Legacy, as they will service any future need and provide maintenance. Highly recommend!Posted on Google Rhonda SaylorTrustindex verifies that the original source of the review is Google. The entire team has been a pleasure to work with from start to finish. They are very professional and skilled at their work, and their customer service is excellent!Posted on Google Joanne EndersTrustindex verifies that the original source of the review is Google. We love our new mini splits! Our house is so cool now, but these mini splits can be used to heat our home during the winter too! Each of the guys who came to our home to complete the installation were reliable, friendly, knowledgeable, professional, and hard-working! Everything went just the way that it should, and we couldn’t be more pleased! If you are interested in installing mini splits, choose Legacy Comfort Systems!Posted on Google Som TimsinaTrustindex verifies that the original source of the review is Google.

Upgrading to a high-efficiency gas boiler offers numerous advantages for homeowners in Harrisburg:
Condensing boilers are designed to capture and reuse heat that traditional systems waste. This means you use less fuel to achieve the same level of warmth, leading to significant reductions in energy costs over time.
Navien boilers are built to provide even, steady heating throughout your home, eliminating the cold spots and inconsistent temperatures that older systems often cause.
By using less fuel and producing fewer emissions, high-efficiency gas boilers are a greener choice, helping you reduce your carbon footprint while enjoying superior comfort.
Navien combi boilers combine space heating and on-demand hot water in one compact unit. This eliminates the need for a separate water heater, saving space while delivering consistent hot water for showers, faucets, and appliances.
At LCS Heating and Cooling, we exclusively install Navien high-efficiency condensing boilers because they are the gold standard for performance, reliability, and efficiency.
Upgrading to a high-efficiency gas boiler isn’t just good for your home—it’s also a smart financial move. With rebates from UGI and federal tax incentives, you can significantly lower the upfront cost of installation. At LCS Comfort, we ensure you take full advantage of these savings opportunities.
UGI, the natural gas utility provider in our area, offers exclusive rebates for homeowners installing high-efficiency gas boilers. These rebates make upgrading to a modern system more affordable:
