"I would give Guardian Heating and Cooling 10 stars if there were a way to do that! These guys are outstanding! They showed up, after hours, to determine exactly what was causing our problem. We had already suspected it was time to replace our boiler since it had been more than 25 years old. Steve confirmed our thoughts about replacement. He quoted a fair price and scheduled a time to come back. He showed up early with the new boiler and within hours after their arrival, we were up and running. We had a little hiccup the next day, as things seemed to be working too well. We called Steve and he was at our house in minutes. We already wondered if the thermostat wasn't able to keep up with the new boiler set up. 30 minutes later, we had a new thermostat and everything was working properly. Steve and Adam were friendly and professional. Our basement was cleaner when they left than before they arrived. Their prices were reasonable and there were no surprises, price wise. We were given a quote and that was what we paid. It's refreshing to find people like these guys!"

"Colton installed a 10x12 gravel base pad for a shed we bought. He did an excellent job! His bid was very competitive with other landscapers in the area and the quality of work was on point. He was on time, respectful, and made sure we were happy with the job prior to him completing the job. I would definitely recommend him!"

"We hired On Board Landscaping LLC to help us with our patio and other areas in our yard that needed updating. The patio turned out quite well and the stones used for the patio were called Bluestone and they are a very pretty blue color and natural stone and greatly add to the beauty of the patio. They also used edging brick called carnelian pairing that complement the main stones nicely. Then he used another stone called Chilton Full Color Flagstone on another area at the back of our house and those stones are equally attractive. We appreciate his expertise in selecting all these stones and we highly recommend his company for any landscaping and patio work needed. He also added Mississippi River stones around the house and that greatly added to the house. His team is very hard working and courteous and helpful. We can now admire how beautiful our patio looks and feel grateful to have it. They also cleaned up the yard after they were done so it all looks tidy and neat."
