Prices were in line with other quotes I received. They reviewed and explained each line item on the quote so I fully understood what was being done. The install team showed up on time and actually finished earlier than I expected. They were extremely professional and courteous. I would 100% recommend Guardian.

Quick response, accurate diagnosis, courteous and respectful technicians (2). My only complaint is that it took two weeks for the part to arrive and to be installed. (Notice this had to be claim to the manufacturer insurance) so it probably not on the company (guardian) fault. I am super pleased with both technicians, both did a great job, organized and clean afterwards.

Leo arrived promptly and installed new 4" duct work for all 3 of my bathroom exhaust fans. Next Leo made 4" exhaust ports with one way valves on soffit to ensure the hot and humid air flowed outside of my house. Great work in a very hot attic! Highly recommend Guardian Heating and Air.
