Outstanding customer service. We have a maintenance contract with them for oil furnace and heat pump. Very quick response, knowledgeable, supportive, and reasonably priced service. Highly recommend this company. read more

I had a very difficult experience with ground loop and unfortunately can not recommend them. Although initially the project was going well, they did not fulfill the project as we discussed and did not install the proper equipment for functioning of the internet monitoring symphony system for the water furnace geothermal in our main house and did not setup the symphony system in our secondary structure system. In addition, it was very difficult to schedule work with them and the project took much longer than expected to complete.They only came out to finish the work properly when we withheld their final payment for incomplete work. Then after completing the work I promptly provided the payment only for them to refuse to provide the final rebate documents needed for the tax credits for state and federal and my state renewable energy credits filing in an attempt to extort me for additional money beyond what we agreed for the project. They have also refused to provide appropriate warranty/maintenance services related to their installation which does not appear to be cooling properly in the main house just months after installation. Needless to say, this was a horrible experience and although they seem to be skilled professionals I do not view them as honest business people and therefore would recommend to stay away. I myself will not be doing additional business with them. read more

We used Ground Loop with great results to service the geothermal system in our previous home. We moved to a different place with oil heat that went through a $500 tank every 6 weeks this past winter. I contacted Ground Loop to help figure out why, as this was an open-ended task that required an experienced technician. They identified a laundry list of items, including some big ones: A large gap in some hidden ductwork that was dumping much of the air into the crawl space, undersized returns and too many closed registers that cause the burner to overheat and cycle off to cool down, they fixed a clogged condensate drain that would likely leak water to the ceiling below, and that the previous owners made the penny-wise decision to install air conditioning instead of a heat pump, so oil is used for all heating. These defects have been present for decades, and probably cost the previous owners a mint. A $297 investment in their thorough HVAC inspection was well worth it. We will definitely be contacting them when we go geothermal in a year or two. read more

We looked into a geothermal heat pump system several months back and Group Loop Heating and Air Condition was one of the companies that responded to our queries. Fast forward to today, and they have just finished up the installation of our new system. These guys were really professional through the whole process. Out of the 4 contractors we contacted they were the only ones who actually showed up in a timely manner, their bid was on par with the other ones we received but it was their professionalism that really got them our business. This was a complicated project and there have been a few bumps in the road, but the reason these guys get 5 stars is how they responded to them. Once all of the county paperwork was in these guys came out and cranked out the system installation and their finishing work is really impeccable. I am super happy with the system and the service I received from Ground Loop and I feel very comfortable recommending them to anybody! read more

Overall I am extremely happy with the services offered by Ground Loop Heating and Air Conditioning. I have an older home (built in 1928) and it still had steam radiators and no air conditioning besides window units. This was a very large job, involving retrofitting the home with ductwork to heat and cool every room, remove the old boiler unit, and install the geothermal unit and ground loops. To complicate matters, the home has a completely fenced yard that limited grounds access to dig the loops, and the city permit office has constrictive rules on where you can dig the holes in reference to other properties. The estimator/project manager, Jason, was very easy to communicate with and I always felt he was being upfront with me on the status of the project. His office staff was also very communicative and even helped with the rebate process to ensure I received all the possible rebates. Great Stuff! The installers were professional and did extremely quality work. The city inspector even commented on how well the ductwork was installed. There was an electrical sub-contractor (I didn't catch the name), but they were efficient and professional. There was also a sub-contractor that dug the wells, Allied well drilling. Their employees were professional and courteous, but it did not seem that the on-site personnel were empowered to make decisions. This did lengthen the timeline of the project. That is not to say this was a perfect project, but I can say empathically that Ground Loop went above and beyond to complete the project with no increase in price, despite several unforeseen issues.. All in all I was very happy, but I do have some things to consider if you are considering a geo-thermal system : The project went well over the projected timeline. While this was not an issue for me (if a bit frustrating), if that is an issue for you, you may want to negotiate some timeline penalties with them before you sign a contract. Most of the delays came from changes in the layout of where the wells were supposed to go. It went from 02 wells to 08 wells, dramatically increasing the time required. You may want to consider having the sub-contractor confirm your local regulations and placement of the wells prior to signing a contract. If you have not had a core sample done (who has?) be aware that there is no way to predict the material makeup of the ground 300 feet down. This may necessitate a change in equipment or drilling method which will add time. It is a necessary evil, and can't be avoided unless they can use their full size well rig on your property. They couldn't on mine, and it caused issues. In retrospect, if I could have moved a shed or some fencing, I should have. Be flexible. Lastly, be prepared to have your yard torn up. It rained a lot during the install, and they needed water in the drilling process, so my yard is beat up, but again, this is the nature of the work. If this is an issue for you, they offer hand raking and restoration at additional cost. If you don't want to put in some work after they are done, you should opt for that option. The end result however is fully functioning system that is very inexpensive to run (the other day it never got above 35 and it only cost $3.89 to operate). I am very happy, and could not recommend these folks more highly. If I had to choose again, I would make the same call. read more

We have been using Ground Loop for our yearly maintenance on our geo thermal system for 6 years. They are thorough and very courteous. Last month we had a ductless a.c. unit installed above our garage in a storage room turned office. They were great to work with! We highly recommend them! read more
