I want to thank you for the opportunity to prove the worth in the quality, care, attention to detail and professional work ethic AVAC can provide to your facility in regards to your HVAC units and overall comfort within your walls. To demonstrate our appreciation for choosing AVAC we offer 15% off our already low labor rates for the term of your maintenance agreement, this includes the labor of your maintenance agreement and any additional issues that may occur during the term of the agreement. Furthermore, our preferred customers take priority in dispatching should problems arise in the heat of the summer or a cold winter snap. However, expediting dispatch is rarely necessary as our comprehensive inspections on your units will usually catch and bring to your attention any issues before they compound into a large and costly problem. I look forward to hearing from you to discuss in further detail the benefits in choosing AVAC to service your facility. In addition I am eager to remedy any unresolved issues you may be having with your air conditioning and heating units.
