I had a great experience with Green Comfort. Spenser did an excellent job — he was knowledgeable and very professional. He arrived fully prepared with the necessary part and completed the work efficiently without any delays. He answered all of my questions clearly and made sure everything was working perfectly before leaving. Highly recommend Green Comfort and especially Spenser for outstanding service!

This is a top-notch company to deal with: from the staff who answers the phone and makes the appointments. To the techs and mechanics who come and do the work. They are knowledgeable and courteous. They are willing to work after hours and have a tech on call. I would recommend anyone to use their service. Thank you for you great work.

I had Dave come out for an emergency visit today, my heat pump has been having issues and today just completely was shut off - leaving me with no heat running. He was extremely responsive, arrived on time, and quickly diagnose the issue and resolve it. He stayed to ensure everything worked properly AND even caught another issue with our unit that we had thought was fixed prior to buying the home, but was not. He was extremely thorough and friendly. I signed up for their maintenance service on the spot and will be having Dave come do work on my boiler to get that running next too! Cannot say enough good things, and they saved me right before this crazy weather this weekend. Highly recommend!!

I apologize in advance for the super long story lol I really never write reviews but I felt like it was a must I write about my experience with Green Comfort Systems. My HVAC was failing, furnace from 2009 frankensteined together and and ac unit that was just put in the worst possible way. I reached out to Green Comfort Systems and spoke to Rhonda who was so prompt and understood my frustrations and urgency to get this done and scheduled Kyle to come out to take a look at my system and quote me a new one the next day. Kyle arrived and we had a great conversation on my options, never at any moment felt pressured or like he was swaying me to go with a certain option he gave me my choices told me what he thought about each and that was it. After doing research I settled on the new Variable Speed inverter system and it couldn't have been a better choice. Rob and Chase came to install the system and their work looks phenomenal they kept me updated every step of the way and their teamwork made the job go by super quick. they also walked me through the completed job and assisted with setting up the thermostat on my phone. I can't begin to say how grateful I am for the entire team that assisted in this process Green Comfort has a customer for life THANK YOU Kyle, Rhonda, Rob & Chase!!

I recently had my HVAC system replaced by Green Comfort Systems, and the entire experience was outstanding. Kyle, the president, personally came to my home for the free estimate and took the time to go over all my options. He was incredibly knowledgeable, honest, and made sure I got the best system for my home at a super fair price. Ron, the installation manager, and his team did an amazing job with the installation. Everything was done efficiently and professionally, and Ron took the time to explain how the new system works. Rhonda, the office manager, was also fantastic—super helpful and made the whole process smooth and stress-free. Not only did they provide top-tier service, but they also worked with me to match a financing offer I had from another company, which made a huge difference. As this was my first time handling a major home replacement, I wasn’t sure what to expect, but Green Comfort Systems knocked it out of the park. If I could give them a 10 out of 5, I absolutely would. Honest, professional, and truly looking out for their customers—highly recommend!
