They did a very thorough air duct cleaning and a great job overall. Initially, they quoted $399 for 10 vents, but because I have a two-story home with separate air conditioning units, they ended up charging $399 per level. a bit pricey, but the quality of work was great.

Had a great experience with Lex from Cal Duct Cleaning. He arrived right on time, explained everything clearly before starting, and got right to work cleaning out our dryer duct. He even showed me how much lint and buildup came out, which was eye opening. On top of that, he replaced my old dryer hose with…
Lex and his team are fantastic. We had a cleaning service done and during it there was an accidental small dent made on the dryer. When we asked Lex about it, he came over personally and spent nearly an hour thoroughly addressing the issue and even made improvements to the work that was previously done. We felt that Lex and his team have a lot of integrity and look forward to continuing to work with them in the future.
