First - the work they did was excellent. This review will refer to the sales management customer follow up. Read the following for why I’m rating only 3 stars.

I got a quote from another local company which was expensive for a job on my personal home. So I called Grassi to get a second quote. I told them the amount the other company was going to charge. Grassi explained that amount seemed WAY too much and that they could fit me in and would be much cheaper! They offered me a quote but said that would slow down the process and recommended I just go straight ahead in order to not waste time as I was hoping to get this job down before the freezing temperatures hit and they had an opening.

Given the assurance - I told them to go ahead and install. Work was completed - and they did a good job.

However, when I got the bill - it was even more expensive than the original company whom I had switched from to save money. I called to ask for an explanation on the discrepancy between what was spoken of on the phone and them now being even more expensive than the original company who had given me a quote. They told me that the bill would not be altered and that I should have obtained a quote - but that I declined the quote. This obviously rubbed me very much the wrong way. I informed them I would pay/ be sending in the bill in full - but that my right as a customer was to leave appropriate feedback on google reviews based on my experience with Grassi Management. Management then told me I was threatening there business and would be pursuing legal action. He told me to send in whatever amount I wanted but that he wouldn’t be cashing the check - because he would pursue legal action for the “threat of a bad review on google.” I explained that leaving a negative review is a customer right based on their experience with a company. It felt very inappropriate for the management there to jump to threats of legal action against a customer for negative reviews. All this over a very small quote discrepancy. The money didn’t matter as much to me as company integrity.

Would I use them again? No - given the negative customer relationship. However, they did complete the job on time and did a good job.

If management would like to reach out to me and smooth this over…I would be happy to change my opinion as the work itself was excellent.

In looking for ways to decrease our energy use, Grassi installed a make-up-air unit over our commercial grill so that we would not be pulling conditioned air out of our building. I was told this would make a significant reduction in our heating and cooling load. I spent $23,000 with Grassi on a new hood and make-up-air unit. We immediately saw an increase in our electricity bill and our natural gas bill doubled. Upon asking about the new equipment having the exact opposite effect of its intent, Grassi's response was "Someone who shops there said your thermostat was set to 75 degrees." One, we have our thermostats at 68 and two, responding with that kind of remark is extremely poor customer service and does not address the underlying issue. Nor did Grassi ever address my concerns.

When hiring a contractor, you are also hiring an advisor who is an expert in their field. You expect good advice on the most appropriate course of action. I went to Grassi asking for ways to reduce our utility bills and was sold an expensive make-up-air unit that had the exact opposite effect of our goal. To say the least, I was not happy with the purchase or the customer service.

The unit has broke down pretty much every winter since being installed, increasing both our operating costs with increased electricity use and natural gas use, but adding additional maintenance costs each year.

The latest; this winter the unit broke down once again. Grassi came to fix it. I get an $815 bill to replace a $9 sensor. Gee thanks for taking care of your customers who bought systems from you.

So now we have a very expensive hood that has significantly increased our operating costs and breaks down every winter increasing our yearly maintenance costs. What a poor investment.
