Jul came to the house on time and he cleaned up an incredible amount of debris from the duct work and inside the furnace due to a major remodel being done; lots of drywall and plaster dust. He showed me before and after pictures; I really appreciated seeing the pictures, a drastic improvement for sure. Jul is a hard worker and I was impressed with his knowledge of HVAC systems. He cleaned the furnace and showed me how clogged up the filter and the blower were. He gave me excellent professional advice on how to maintain my furnace. I highly recommend Ductworks!
