Client Testimonials


For nearly 50 years IHS has helped customers harness the power of information to improve their business results.

HVAC service is a very critical aspect of Property and Facilities management. When choosing an HVAC company it is of course important to make sure they are qualified to handle your mechanical needs. However, it is also critical that the company have a top to bottom philosophy of delivering outstanding value and customer service. With Haynes Mechanical Systems you not only receive the finest possible service but an overall company commitment to keep your systems in peak operating condition at all times.

I have been associated with the Haynes team of professionals for over 25 years and recommend their services to anyone looking for a quality HVAC service provider.
