"I used Regal Duct Cleaning today. Our home is 60+ years old. We have only lived in it for 20 months and there was more dust, dirt and webs than I had ever imagined. Julius and his crew arrived at the scheduled time. He was extremely professional. We went from room to room looking at every every vent, cold air return. His crew worked for five hours, cleaning the ducks, dryer vent and installed a UV light. I highly recommend Regal Duct Cleaning . I will definitely use them again! To see the before and after pictures was a real eye opener. Great Job!"

"They charged $98 to come give me an estimate for swapping our a shower valve cartridge, which was fine, but the pricing they provided was completely unreasonable, $1,000. They were unwilling to provide any detail for the price. I ended up buy the part myself for $30 and replaced it in 30 minutes."
