"WARNING - make sure you get a fully price estimate up front before they begin to do work. I brought them in to work on furnace/AC unit/split AC unit servicing garage (based on a promotional price for the first two). It was found my split unit needed a recharge for coolant and I was told that it'd only be 5 lbs of coolant and that this would be priced by the pound (which was reasonable). The bill came and they tacked on a flat charge of $219 for the coolant (this is in addition to the $129 charge to look over the split unit). I felt baited-and-switched. I also contacted them about this, and the answer came down to "This is additional profit for us added onto your bill." Not pleased. At all. Particularly since the coolant in question costs approximately $6 per pound and they only used 5 lbs (one would assume that the $129 charge built in enough profit for labor/licenses/equipment due to the limited time spent working on the split unit. Apparently not). Comfort By Design does excellent work, and they do stand by their work, but just be VERY CAREFUL in finding out what they're going to charge you, particularly if something extra comes up when they're doing a job."

Most standard ductwork rerouting projects require between one and three days for completion, though complex installations may extend to a week. Factors affecting the timeline include accessibility of work areas, whether walls need opening, and the discovery of unexpected issues like asbestos or mold.
Projects involving multiple rooms or requiring extensive modifications naturally take longer. Scheduling during moderate weather seasons minimizes comfort disruptions while your system is temporarily offline.
Properly redesigned ductwork can significantly improve energy efficiency in many homes. Inefficient duct layouts may waste 20% to 30% of conditioned air through excessive length, leaky connections, or poor insulation.
Professional rerouting creates more direct airflow paths, eliminates leakage points, and often includes improved insulation. These enhancements allow your HVAC system to operate more efficiently, potentially reducing energy consumption while improving overall comfort throughout your home.
If you suspect asbestos in your ductwork or surrounding materials, immediately stop any work and contact a certified asbestos inspector. Asbestos testing services cost between $250 and $700 to confirm the presence of this hazardous material. Professional removal, if necessary, ranges from $700 to $2,200 depending on the affected area. Never attempt to remove or disturb potential asbestos materials yourself, as improper handling creates serious health risks through airborne fiber release.
Permit requirements for ductwork modifications vary by location. Many municipalities require permits for significant HVAC system changes, especially those involving structural modifications. Consulting your local building department before beginning work ensures compliance with regulations.
Working without required permits can lead to complications, including potential fines, insurance coverage issues, and disclosure requirements when selling your property. Professional HVAC contractors can handle permit applications as part of their service.
