Steve came out to clean our dryer vent and it turned into a much bigger job (broken vent pipes and clogs) than a simple cleaning. Steve was willing to come back to fix the pipes and make sure the dryer vents were in 100% working order before he considered the job done. Awesome Job!

Very easy to deal with and transparent on pricing and timeline. 2 years later, the unit is performing like new. I will hire again as I have 2 other units that will need to be replaced soon.

I love the fact that Steve Wilson uses an all-natural, plant-based cleaner when performing the maintenance on our HVAC systems. He is responsive, efficient and very knowledgeable about HVAC systems. If you want a clean system without the toxic chemicals used by others, Steve's the man to call!
