Letters of Recommendations

What some of our clients say about NKS Mechanical Contracting, Inc.

Please accept this letter of recommendation for NKS Mechanical, Inc. on behalf of the Laguna Beach Unified School District. Our district was introduced to NKS by way of a large mechanical replacement project we had at El Morro Elementary School in the summer of 2015. NKS was our lowest responsive and responsible bidder for the project, which included replacing nearly all HVAC units at El Morro.


NKS was highly responsive throughout the entire bidding and construction process. Their team was highly professional and delivered the project well within the required timeline. In addition, their technicians kept the construction site very clean and the finished product was excellent. We had multiple construction projects occurring al El Morro beyond what NKS was completing for us and they were able to successfully coordinate all work to not interfere with other contractors on site throughout the entire project.

Our district was so pleased with the quality and value that NKS demonstrated on the project at El Morro that we have since relied on them to provide additional maintenance and repairs on HVAC units at all of our sites. It is without hesitation that I highly recommend NKS to any organization looking to repair, replace, or service their mechanical systems.

I would like to take this opportunity to convey my pleasure in working with NKS Mechanical and everyone associated with the company.

Initially, we were concerned with the project schedule and performing the working during school time. But as the project progressed, these concerns erased. The detailed schedule you provided made it perfectly clear which path and date the other trades schedule had to be met. This type of scheduling actually enhanced the performance of all the trades.


The scheduling of the air conditioning installation for the entire project was very precise and executed exactly. Everyone on the jobsite was informed as to what was needed prior to the installation and when it should be done by. This allowed us a unique opportunity to pressure the other trades to get their work completed or move on because the floor was coming.

In closing, as NKS Mechanical Contracting Inc. strives to deliver the highest quality projects, we rely on highly qualified subcontractors like SJL Piping and Plumbing. At times we didn't even know you were on the jobsite. If we wanted to know when a certain area was to be installed or ready for traffic, we just looked at the schedule. Your scheduling and working together as a team member is commendable.

We have recommended NKS Mechanical as a General and mechanical contractor. it would be a pleasure to have NKS Mechanical on the team in the future.

I am writing this letter of recommendation for NKS Mechanical, Inc. (NKS) on behalf of AECOM Energy. Working with NKS was a pleasure as they are very knowledgeable about the HVAC systems that they installed. Their professionalism and great ability to communicate exactly what they project needs to be a success.


NKS worked on our Huntington Beach Unified High School HVAC project which consisted of replacing (9) existing Air Handler Units (AHU) with new custom AHUs. The project consisted of replacing 9 units on the roof of an active high school. NKS arranged to have 3 cranes operating simultaneously to remove the old units while installing the new units. This resulted in only using one day to accomplish this task which made the Client happy as it did not disrupt ongoing school operations.

I could not be happier with NKS and all of their personnel. The client was thoroughly pleased and has already started talking about a Phase 2 project. I would definitely use NKS again in the future.

NKS Mechanical was the low bidder on the HVAC Replacement Buildings B&C at Diamond Bar High School. The project presented NKS Mechanical with two main challenges. The first was the unit replacement required a risky helicopter lift of very large custom built Seasons Four package units. The second was a very demanding schedule requiring close coordination between all of the subcontractors working under the pricing contract issued to NKS Mechanical Contracting, Inc.


The scope of the 2 month project involved HVAC, building controls, plumbing, electrical, roofing, and framing in addition to equipment and material. The total cost of the job was $990,000. NKS was able to meet and exceed the project challenges by providing close pre-construction services. They provided excellent subcontractor coordination and selected a subcontractor team that was responsive and provided high quality installation. During the job, they recommended an alternate safer method of lifting the units using a crane that enabled them to complete the job on time and with one change order added to the scope of the District.

NKS Mechanical did an outstanding job in providing a high quality installation along with beating our highest expectations. From our experience with NKS Mechanical, I am sure that they can meet and exceed the needs of any difficult project. We would use NKS Mechanical in any future projects and we would highly recommend them for any other agencies taking on such a difficult job.

NKS and their crew were very good to work with. They were very responsive to the needs of staff and made reasonable accommodations with employees when working in their areas. They kept areas clean after they completed each step of the installation.


They were very responsive to our needs and made every effort to resolve differences between the architectural plans and the actual building construction. They were very innovative and made changes with least amount of impact on completion time and budget.

The project is on schedule and is 90% complete. The project is on budget and the only extras were the addition of a unit not part of the project and an improvement in the design based on request from the District.

Their workmanship and accuracy is exceptional. They take pride in their work and strive for perfection.

There were some discrepancies between the plans and what was actually behind the walls, but NKS worked to accommodate all of them with minimal impact to costs or delays.

We are 90% complete and we are very satisfied at this point. All the units have been installed and all piping has been vacuum and pressure tested. We are looking at total completion in about 2 weeks.

We would use NKS again and we feel very comfortable about recommending them to others.

As the owner of CJK Construction and the Capistrano Unified School District Owner's Representative for construction, it was a pleasure working with NKS Mechanical Contracting Incorporated. The heating ventilating and air conditioning (HVAC) system replacement at Newhart Middle School was done in a timely manner and met all of the specifications at or above satisfactory level.


Throughout the entire course of the project, NKS maintained a respectable and professional level of communication that retained our high level of confidence in their quality of work. The worksite was well-kept and sustained a high level cleanliness throughout the entire course of work that propagated a safe environment for all to be around. As well, we were consistently included on any and all issues that may have arose and NKS provided an essential role in reaching workable solutions.

Following the completion of the project, we were happy to confirm the highly regarded reputation that NKS has built for themselves and would gladly recommend them for any project that you may have. Their team minded approach creates a positive atmosphere and we look forward to potentially working with them again.

If you have any questions regarding this recommendation, please do not hesitate to contact me.

Please accept this letter of support for NKS Mechanical. This HVAC contractor has recently completed a multi-site rehabilitation project for the City of San Dimas.


This project included replacement of rooftop packaged units on five facilities and a new VRF system for our Senior Center. Several of the sites received new condensing units, upgraded electrical, new programmable thermostats and minor ducting work. NKS Mechanical completed the work as directed and provided a complete project at the conclusion of the contract.
