Elliot did a great job fixing our furnace. He was able to locate the problem in a timely manner. Will definitely recommend him to my friends and family.

Great customer service since 2008. I have never been disappointed or had concerns with work provided. I recommend for HVAC issues or questions give Greenwood Heating & Air a call.

Always a pleasure working with Greenwood! My system was installed in 2022 and this was my first experience with a minor problem. Quick to respond and schedule for my convenience. Today’s service call was an education for me luckily and not a major repair.
