"On 7/6/20, James Sweitzer of Grove H&C arrived promptly at my home in Crofton. He politely explained to me what he was going to do to determine the problem. He determined the problem (Capicitor) and informed me of the the steps needed to correct. He then quoted me the price (Very Fair}. i gave him the OK to proceed. Problem corrected. I would highly recommend Grove H&C. Their technician was most competent and courteous. Estimate is provided prior to work and the price is very reasonable. Could not be happier with Grove H&C and its technician, James Sweitzer!!"

"They were by far the best salesman. They did use and leave the manufactures sales aids. Also the only contractor to leave a complete check list of everything that would be done. Andrew was the only one out of four to point out the fact that the old furnace was installed in a non serviceable position for removal of the circulation fan. Extra work was done to correct this problem. Next day instillation was just as impressive. I met four people from the company, and all were professional. All of the above came with the best price.

"We were very happy with them. I think, they were very punctual, I would probably remember if they weren’t. I think, it took one day to install the system. They left the area cleaned and took away the other unit."

"Project: Move our Heat Pump location. Very professional, courteous, respectful of our home and work area. Great people to work with. Will be my "Go To" for future HVAC needs."

"The plumber that came out was professional and knowledgeable. Talk me through the process before starting and after installation cleaned up well, then tested everything to make sure there was no leaks in the system."

"Excellent. The estimator, Shane, quickly responded to request for a quote and was the most thorough and knowledgeable of all the estimates I received. He was very open about different options, benefits and costs. He thought job would take 1.5-2 days but texted me a few days before install and said that they could possibly do job in 1 day if started early. I said that was fine but asked them to not come into house before 8. Installers showed up before 7am, started working outside and did not ring the door bell until 8:02 that morning. Not only did I get the two AC and one furnace, but they also installed Nest thermostats and helped me program them. All in all, excellent experience from beginning to end."

"I couldn?t be happier with the experience. Graham Solution handled the entire installation from start to finish, and the quality of the work was outstanding. He was professional, knowledgeable, punctual, and paid close attention to every detail. The installation was completed efficiently, everything was left clean when the job was finished, and the system works perfectly. It?s hard to find someone who takes this much pride in their work, and it definitely shows. I highly recommend him to anyone looking for reliable, high-quality HVAC installation. Excellent workmanship and great customer service from start to finish!"
