"Everything went extremely well. I found Grove a completely professional organization with highly skilled workers. Their plumber subcontractor handled the installation of all gas piping in my house, oversaw the hookup with BGE's gas line and installed the hot water heater. Grove provided a skilled crew of 5, with 2 working outside and 3 inside to remove all old equipment, do some duct repair and install the new air conditioner, gas furnace, humidifier and thermostat in 2 days. They also removed all debris from the worksite and swept it clean. Their work proposal included a year's maintenance, which I feel sure will be equally satisfactory. This was a big project (3 days including the plumber), but I am confident they would handle both small and large jobs with the same competence and professionalism. I highly recommend them."

"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."
