“Hello online community I wanted to express my complete satisfaction about the service that was rendered to me . The ordeal occurred July 3 2026 my Heating/ AC unit took a dirt nap ! We were experiencing the one of many heatwaves for this area in the tri state area. Needless to say it was very bad very overwhelming conditions for anyone caught without cooling capabilities. I place a call to Moon HVAC and the a gentleman named Jason came out to Newcastle de and sold me an entire unit . He was fair and knowledgeable about his craft , I liked him a great deal , a professional and good dude all around . The techs were equally impressive Dom and Cameron were spot on and took care of my crisis and need . I sincerely thank them . If you need honest and fair installation look no further than them!”

“Matt cleaned my furnace system this morning. He was extremely professional, informative and personable. Matt explained everything he was doing and even gave me tips on upkeep of the system. He showed me my options for a possible repair I may need and he never was pushy as sometimes repair people can be. He gave my advice on getting it done and was very understanding of my situation. I would recommend Moon and Matt to anyone looking to have your furnace serviced.”

“This was our first experience with Moon Air and we were so impressed from the intake call all the way through the service call. Chris came and spent a good amount of time assessing our AC unit and was very careful to fully diagnose our issue. He was polite, kept the area clean while he worked and explained every thing he was doing. Thank you for such great service!”

“I hired Moon Air for air duct cleaning at my house on 8/15/25, and Nate and Adrian were assigned to the job. Unfortunately, my experience has been deeply disappointing, and I feel compelled to share a few SERIOUS issues. First, after the cleaning, my dryer—which has always worked flawlessly—suddenly malfunctioned. When I turned it on 8/16/25, it made a strange noise and shut off within a minute. The heat coming from inside was extreme (even though it was set to low), and there was a strong burning smell. I have never encountered this problem before, and I find it extremely unsettling that this would happen immediately after the cleaning. To add to this, when Jason, the Project Manager sold me this service, I was told that dryer vent cleaning was included, but Nate and Adrian were completely unaware of this detail. Secondly, while removing the registers, my recently spackled and painted bedroom walls sustained considerable damage. Their only solution was to caulk around the registers—without clearly explaining to me what had happened. I would NEVER have agreed to caulking as a fix, especially since I paid less than a week ago, $5,000 for the bedrooms to be freshly spackled and painted. Now, I have the added burden of removing the caulking and repairing the damage, which will cost even more money. Lastly, not all registers were cleaned as promised. One in particular, located in a bedroom, was completely missed. I sent photos to Jason that show what I was able to remove myself with a simple Q-tip for evidence. In summary, I am furious and devastated after paying $1,100 for a service that has led to damage and frustration in my home. At this point, I have zero confidence in the work that was done and would not recommend Moon Air to anyone considering their services. In sum, the cost for me to have air duct cleaning was $1,100 for air duct cleaning to Moon Air, plus $$$ to my contractor to repair walls, AND potentially the cost of a new dryer. PLEASE RUN from Moon Air. I feel as if I’ve literally been robbed…they’re a complete scam. I sent Jason an email and spoke with Tammy this morning. I have heard nothing…crickets, chirp, chirp… NOTE: Moon Air’s below response is completely inaccurate. They never spoke to me after their repairman came to my house. First, the repairman was very nice gentleman but the reality is when he looked at vents he stated it was obvious Moon Air just pulled them from walls which is what caused damage. The photos show the issues…had NOTHING to do with moving equipment through house?? Second, my house is now only repaired due to my hiring and paying my contractor to fix the walls and paint around my vents. The only truth in Moon Air’s response is they sent a repairman.”

“Moon Air responded quickly to my call and Adrian came right out, even though it was after hours. Adrian was courteous, efficient and very thorough and repaired my system while explaining the steps. Henis amazing and Moon is great.”
