To who ever reads this, I would like your opinion on a question that I have. I am thinking about installing a central ac system in my house. To start I have no duct work. Should I install a unit that consists of duct work? If so then I could include a gas fire furnance. Or I could go with the ductless units. I would like to know the pros and cons of both units. I would especially like to know the opinions of people who have installed and serviced both units. In the long run I would like to know what one would be most dorable and cost efficient. I appreciate anyones comments on the two systems and what my best route would be.
