"Outstanding customer service. Very professional, knowledgeable and courteous. They replaced an old AC and provided several options for purchasing and upgrading to new energy efficient unit tailored to my needs. I am enjoying my new smart thermostat that adds a new level of comfort, efficiency and ease of use. They went above and beyond to resolve an unexpected issue. Very pleased with service and results."

"Littleton Heating & Air did a fantastic job assisting us with our air conditioner. They were professional, fast, and friendly. Additionally, they were upfront and honest about what they were going to do and with any questions we had. Strongly recommend using them for any HVAC needs!"

"To say these folks are the best H&AC company I have ever worked with is no exaggeration. Derrick and Derek are the best and most knowledgeable professionals I have ever worked with. They executed one of the more complicated projects you could ever have with a full system tear out and rebuild. I will always use Littleton H&AC for my homes in Denver."

"We selected Littleton Heating and Air Conditioning after our AC went out. We also decided to replace our aging furnace and add a humidifier. While getting estimates, I noticed others only wanted to replace the AC and furnace with similar units and didn’t have options when it came to humidifiers. What stood out during the estimate with Littleton Heating & Air is you are meeting with an actual technician, not a sales person. They evaluated our ENTIRE system, including how air ducts from the utility room could be reconfigured to allow for better air flow. No one else bothered to consider that. They offered higher seer AC units with multiple speeds that are more energy efficient and quiet. I liked the fact they are a local company offering personalized service and not a big chain. Their reputation is important to them and they stand by their work. They focused on the job taking all the time needed to do a thorough install. I am pleased with the results and know if I ever have an issue, they will be quick to respond. Dave T."

"I was so impressed by Littleton Heating and Air. After receiving a few estimates for a new heat pump and furnace, not only did LH&A come in competitively, but they were patient, explained our options, and worked around my tricky schedule. The install process went very smooth for both units, and I'm blown away at how well both units are working, especially the heat pump. This summer I've saved over a hundred dollars a month on electricity bills, the house is noticeably more consistently comfortable, and the heat pump is small and so quiet. I highly recommend LH&A, I'm very happy with our decision to go with them."
