Manny, from Thunder Ducts. is a safe and sure choice when choosing a company for your home. From the start - he was professional but his compassion for my predicament was what really impressed me. Manny, who already admitted that they were booked solid for two weeks, promised me he could fit me in. You see, I had sold my home and had to make this one repair before closing on the house. I had one window or opportunity to make this happen. He not only came to scope my ducts immediately the next day - but promised to get me taken care of. Although my AC has to be off for four days to let this rubberized spray to cure, it's something I'm more than happy to do (even in the hottest summer temps) because I know the best of the best is taking care of me. My favorite part? Watching the spray being applied across the affected areas. It was the coolest thing ever! And it comes with a 15 year warranty. I highly recommend Manny and his company. On a side note - Thunder Ducts only repairs your ductwork. You'll need a separate AC company to pull the coils from your furnace so Manny's company can access the ductwork. read more
