Ductwork is a pain and not necessary anymore. Most people have homes with ductwork because they own a central HVAC system. The point of central HVAC is making the whole home one temperature. Every room in the house gets heating and air because the ductwork stretches in the walls of the home. The air vent then releases the air in each room. In theory, ductwork sounds great. Every room is cooled and heated the same quite easily. The problem is that ductwork is just not that good. The air ducts are quite delicate. The seams frequently get tears in them and a crack can form within the air ducts too. If there is even a small hole, the energy bills go up. While the HVAC works, the air goes right outside through the hole. The HVAC continues to keep working in order to achieve the temperature on the thermostat. It never can since most of the air is leaving the home. The HVAC will eventually burn itself out and either need a large HVAC repair or just turn off. The house won’t be the right temperature and the bills will be higher. Finding the hole is not easy either. It can be as small as a pea and really mess up the home. The HVAC professional can’t really see the air ducts either. For ductwork sealing, he blows air through the air vent with sealant particles. It is a lot of guesswork on something very major. Why go with ductwork and central HVAC then? There are ductless options out there that take away these problems.
