I can’t say enough about how pleased I am with the work Alpha Tech Mechanical has completed on my home. They performed a full system replacement including the duct work for my upstairs HVAC system. I work in the software technology field that helps supports many aspects of Facility Maintenance and have extensive knowledge of this industry. Alpha Tech Mechanical fully understands HVAC and building science in every detail and applies industry best practices in their work. In my experience with other HVAC companies they simply do «break-fix» repair but never try to or want to address overall system issues. This is in part because it may not be the most profitable approach for their business or lack on industry knowledge. Additionally, many other HVAC companies either don’t care or don’t know how ensure your HVAC system is performing to optimal efficiency and capacity. Jack and his team truly understand all of this and therefore can take a completely different approach. Alpha Tech Mechanical took their time and walked me through their thorough diagnosis they performed on my new system during the commissioning process. This ensured me that the system they installed was performing to desired specification. After all was said and done the results showed that the system was performing well beyond the manufacturer specifications. I fully accredit this to Jack and his team doing what I would consider the best quality work I have ever seen in residential HVAC. Here’s to Building Science and Thank You Alpha Tech Mechanical
