MASSMANN GEOTHERMAL & MECHANICAL LLC

We were very pleased with the work Jason and his team did for us. His pricing was very competitive and he did a thoughtful design of our system. He had very professional workers and left our mechanical room looking pristine, well organized, and meticulously labeled. He ensured our rebates were processed and did a great job explaining the complex system. We moved into our home in late January 2015. We have 6000 square feet + large garage -- our gas bills thus far have been $0 for heating. Our electricity bills for Jan and Feb were a couple hundred bucks, but went back down to sub-$100 for the whole house beginning in March. We are delighted with our quiet, toasty home and the crazy low bills! I would recommend Massmann without any hesitation!

Jason and his team were amazing! Jason was on site for most of the install and available for the multitude of questions that I had before, during and after the project was completed. His office staff was responsive when I had questions about the types of filters and how to get them. Jason even made himself available when there were issues with the dual fuel meter and even went above and beyond to get those issues resolved even though they weren't his to solve. I would highly recommend Massman Geothermal!

They were A-1.

Massmann was the low bidder, they got the work done on time and within budget but the system is not performing to spec. Every time they come out to try to get the system to run within specification, they send a bill even though it should still be covered under warranty. It is near impossible to get them to come out to do service work and they charge an arm and a leg for anything after the original install. I would not recommend.

Communication, responsiveness, and willingness to work with my particular situation was very good initially. I had a few breaks in timeline where I needed to wait until the next phase was to be completed, so the scheduling was more difficult than normal. There was an issue with a subcontractor nicking one of the loop lines which caused some issues with the system later, but there have been other issues unrelated to the loop field such as improper condensation drain installation, and a circuit board failing in the heat pump. Ductwork installers were also very friendly and did a good job at execution, but the planning was sorely lacking. There are two main trunk lines coming off the air handler, but one of them is straight out the top (more direct pressure) and the other off the side. That would be fine in itself, if the supply lines were balanced off of this concept (more connected to the one with higher pressure), but that's not the case, resulting in very imbalanced pressure at various supply runs throughout the house. In fact, I needed to request that the installers make it less out of balance than it already was. The best thing to say about this company is their repair person, Jon. He's exceptional, albeit busy - Jason needs to clone him for the installations. He's always responsive, explains everything, and bottom line - gets it fixed. This is more of an indictment on geothermal, but the savings have not been nearly as good as anticipated (or advertised - Jason said it'd be a 10 yr breakeven point, which won't be even close to happening). The compressor is a power hog and comes on quite often. Granted, I have a leaky house built in the 60s, but I have the same utility bills as I did with gas (with the same lack of insulation).

I called Massmann Geothermal after hearing their ads on the radio. I left a message for Jason. He didn't return the call so after a few days I sent an email. No response. I waited another few days and called again. I left a message inquiring about geothermal heating to be installed. No call was returned.

Jason is reliable,prompt,professional, and I would recommend him to others.
