Paying it Forward

We’ve included a space on our web site entitled After Work.  It doesn’t have much to do with business. But, as you know, most of us have a life outside of work.  After Work is our way of sharing some of our interests with you.  Many of our customers and close friends have partnered with us and we want to say a big thanks!  Perhaps you know of needs in our community that we can help address.  We care about our community. Bring them to our attention – maybe we can help. Perhaps you would be interested in working with us on some of our “extra curricular projects”.  We would love to have you involved. Feel free to call us for more information.    Read more…

Helping Communities In Need

ACS Mechanical is appreciative of the many opportunities to serve our clients and friends however we also subscribe to the philosophy of community involvement. We believe there is great value and fulfillment in offering a helping hand to others whenever possible. We’d like to take this opportunity to share some of our “extra-curricular” activities with you!

Back in 1998 Hurricane Mitch stormed through Honduras and left a trail of devastation and destruction behind. A unique situation presented itself in which our organization was able to provide services to help in the development and creation of a children’s orphanage. Over the years, significant progress has been made in Southern Honduras and we continue to provide as much support as possible. If you’re interested in the full story, please visit

We would like to extend a special thanks to Aries Freight for their participation.

Increased Value through HVAC Improvements

The technology of a modern HVAC system has existed for some time, therefore the technology is well known. More recent advancements have been driven by change in consumer requirements or federal regulations. New refrigerants have been developed to protect our environment and reduce energy consumption. Improvements in materials and manufacturing have reduced relative costs while significantly improving quality. Modern systems, when properly installed and integrated deliver a great deal of value for the cost.

Our Service is Founded on Quality and Integrity

What then, differentiates each vendor when we all have equal access to the same technologies? The answer of course, is craftsmanship and integrity. Poor craftsmanship will always trump good technology. It becomes a slippery slope when a quality system is poorly installed, improperly integrated or badly maintained. Faulty design, misapplication or leaky ducts to name a few, quickly erase the advantages that new technology promises when costs begin driving up your energy bill.

Below we have showcased a few of the recent projects we have done in past years.

Personally Invested

ACS first opened our doors in 1977 and has maintained the same high standard of ethics and ownership ever since. Our personal investment into your HVAC needs is a guarantee that you’ll never be “lost in the system.” We strive for flexibility, understanding and ease to ensure overall satisfaction from our clients.

NATE_logoLet’s consider the benefits of a homeowner using a contractor who employs certified technicians. Ask yourself – is it important that the technician working on your heater or air conditioner:

  • Knowledgeable in heating and cooling technologies and systems
  • Has licensed documentation of his/her knowledge
  • Is proficient in diagnostics and repair
  • Conducts repairs to manufacturer’s standards
  • Provides quality parts and efficiency

*If your answer is “no” to any of the above specifications, please exit this web page. We will not lower our standards to help you.

Certified Technicians

A certified technician means you are confident that you’re receiving the best experience for your hard earned money. NATE certified technicians are proficient in heating and cooling. Certification does not ensure that a technician is more advanced than an individual who lacks certification however anyone is capable of claiming knowledge, experience and qualification. The key difference accompanied by a NATE certified technician is that the technician has been tested, approved and certified by a knowledgeable, impartial third party. North American Technician Excellence or NATE is the nation’s largest non-profit certification organization for heating, ventilation, air conditioning and refrigeration technicians. The U.S. Department of Energy endorses NATE.
