"Grove Heating & Cooling came to the rescue 5/17 after another local company couldn't complete the job. We needed our heat pump/compressor moved for the installation of a patio then reconnected. The "other" company disconnected then couldn't schedule to finish even after giving them a months notice ahead of time. We found Grove and gave them a call. It was after hours and the on-call tech returned the call. He wasn't able to come out that night but made sure to call to schedule the very next morning. By noon we had service to reconnect the heat pump and 3 hours later we were up and running. Everyone at Grove were so responsive and went out of their way to make sure we felt like a priority. You can really tell why they have been in business as long as they have been with how well they treat their customers on top of being technically proficient. Our family is now a super fan and advocate for Grove. Highly Recommended! Mike"

"Continental's technicians were highly experienced, professional, considerate, respectful, hard working, and neat.  They arrived on-time when scheduled.  Allied's drilling and trenching crews were excellent also.  This was a big messy job that took about a week and we are very happy with the work that they did.  The owner of Continental, Frank Jackson, sold us the system.  He provided an extensive reference list that went back at least 15 years.  He was on-site for most of the job providing hands-on supervision of his technicians.  His technicians are so experienced that he didn't have to be there to supervise them.  Rather, I believe he was there to make sure that the job was finished on time because they are so busy.  Allied had an on-site supervisor at the start of the drilling process to finalize the location of the loop bores, but their drilling crew was highly experienced and needed no supervision.
Installing geothermal is a messy job.  The vertical bores and horizontal trenching for the ground loop makes a muddy mess.  The drillers from Allied were very respectful to the property, much more than I expected.  I expected that the drilling process would make "a mess and a half" but it only made a mess!  At the end of the job the ground was re-leveled and ready for seed, which has already popped and growing grass.  As one of the drillers said "the mess only takes grass seed to fix".
The HVAC technicians from Continental left the spaces where  they worked in "broom-clean" condition.  We had to do some "deep cleaning" afterwards, but this was completely reasonable.
We expressed our concerns about the job to the technicians before they started work because we do not know much about HVAC or geothermal.  They took the time to explain what they were going to do and how they were going to do it.  They kept us fully informed about their progress and included us in the decision making process when they had more than one way of running a pipe or duct.  They made us feel really comfortable and that we were getting a top-notch job.
While the cost for the system from Continental was a little bit higher than their competitors I think we got value for money.  In addition to the reference list we received during the sale process, we also know two families that used Continental in the recent past and they are very happy with the work that was performed.
We would use Continental again and would recommend them to others.
If you go with the option to integrate your hot water heater with the geothermal system (which is supposed to reduce the cost of the hot water that you use) I would reccommend that you bite the bullet and have a preheat tank installed at additional cost.  We didn't do that and in retrospect we should have based on some further reading that we did about how to get the most bang for the buck from geothermal.  It would be easy to install the preheat tank during a new construction project.  It would be harder to install the preheat tank during a replacement project (like ours was).

"It was great. I have a very old boiler and they send out knowledgeable mechanic to to the check up for it. And once the worker didn't know, another came in and fixed it. They deliver my oil and are very efficient."

"I hired someone so that it could be done correctly. I have a 3 level townhome and wanted the 3rd level pressure washed from a ladder, downward. The pressure washer did the whole house from the ground. I am aware of the potential damage pressure washing siding from the ground above the 2nd level can cause. Also they used the pressure washer on the window and water got into the home. For the price it was ok, but I wouldn't hire them again."

"Technicians were very professional and polite did the installation the same day
"

"Great job. Quick, thorough and effective. All done remotely...
Would recommend and use again.

"There was only one hang up. When I contacted them through e-mail I indicated that I wanted to talk about installing an antique wood burning stove in addition to the chimney inspection and cleaning. The appointment was made for the afternoon on a certain day. But, the guys called that morning and left a message on my voicemail saying they could come early. I did not get the voicemail and they showed up early anyway. I was not home but my mother was there. Unfortunately, these guys did not get the word from the scheduler in the office that I wanted to talk about the installation of the wood burning stove in addition to having the chimney cleaned. So they came did they work and left. I called the workers back (since I had their phone number from the voicemail) and communicated my annoyance at the schedule change. The guy was very apologetic and offered to come back though he was no longer available at the scheduled time which I had blocked off on my calendar.
However, we ended up talking about the project over the phone and he was able to give me all the information I needed about the potential installation over the phone. He was very knowledgable and helpful. So, I'd like to give them a "B" for punctuality though that doesn't seem to really fit the situation. So they get all As despite this little hitch.
