Happy Customers

We hired Dana from Brooklands Design to evaluate our prevented maintenance contracts for cost and accuracy. He did a great job and was on time and was cost effective. He pointed out some missing items, so we had an apple to apples comparison and brought some items to the table that were not on our radar screen and could of cause production down time.
It was well worth hiring Dana for his experience of mechanical systems.

The company I worked for was interested in adding new boiler and Chiller plant to back up the existing Equipment and add redundancy. Dana put together a layout and specification with a budget that we could have our board review and approve. We were so comfortable with Dana we hired him to oversee the project and managing the subcontractors until the job was complete. This allowed our company no interruption or shortage of staff.

My Husband and I were having a new house built we hired Brooklands Design to design a high efficiency heating system with radiant heat in some rooms and Panel radiator in others. We also wanted an area of snow melt for our front walk and in front of the garage doors to elevate shoveling in our later years. Dana work with our Heating Contractor and Builder to coordinate the design and installation. We would recommend him to anyone. Thank you for a great job!
