Had ducts cleaned by Safety King (Bill T. and Vernon G.). Very professional from office call(Kerry P.) to the time they left my house. They were extra clean and did what they said was going to be done. The guys were at my house for 7 straight hours. They took pictures of before and after cleaning. I had cleaning done at my last house and it was cheaper than Safety King. The last company took 2 hours and it was 2 guys and oversized shop vac. They did not do a good job, did not access duct work and left basement dirty and dusty. Safety King went above and beyond what I expected and I will use them again in the future. Kevin T.
