"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.

"Brian and Ray H. arrived at 8:00 a.m. and started working immediately and they both worked very late to ensure that everything had been installed correctly. They had a lot of work to do in order to install more modern equipment. Both Brian and Ray H. were very professional and kept us informed on what they were doing. We really appreciate both of them because they made sure that these two old people had heat once again. We would hire McCrea again."

"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!"
