Gas Heating and Furnace Service
$8,000
I couldn't be more thrilled with the service I received from Mark at Fabtek! From the very first consultation to the final installation of my new AC unit and furnace, Mark delivered top-tier professionalism, craftsmanship, and care. He took the time to walk me through all my options, answered every question patiently, and made sure I felt confident in my choices. The installation itself was smooth, efficient, and done to perfection. You can tell Mark takes great pride in his work—everything looks clean, functions flawlessly, and was completed right on schedule. He even went above and beyond to ensure the space was tidy when he finished. And the pricing? Incredibly affordable, especially considering the quality of work and equipment. No hidden fees, no surprises—just honest, excellent service. If you're looking for someone dependable, skilled, and fairly priced, look no further than Mark at Fabtek. Highly recommended!

Mark did an excellent job on my basement. He installed all the duct work and separately zoned it so my soon-to-be finished basement has its own zone. He is also a great guy to work with.

Fabtek provided fast service when my furnace went out and had it replaced in 2 business days after coming out to inspect my 25 year old furnace. Very respectful of property bringing drop cloth and sweeping work area (left it cleaner than it was before work started). Competitive pricing and had estimate to me the same day if inspection. Would definitely use again in future!

Mark was, professional, friendly, and got the job done. He cleaned everything up when he was done, which really impressed me as I have some messy projects of my own going on. I would hire him again and would recommend him.

Fab Tek installed both a heating and air conditioning unit in our Summer home. Very happy with the work, finally had a chance to test both the heat and air conditioning and they are working great! Would recommend Fab Tek to anyone needing HVAC work done. The customer service was top notch.
