I will divulge that I have gone a bit hog wild when it comes to updating our house.
When I first bought our house I figured I would only add a fresh coat of paint, but then I started looking around and realized it would be smart to get the big, messy projects done before I moved all our stuff in.
I ended up ripping all the flooring out. The seasoned carpet went out and the brand new brick went in. I am so thankful that I decided to add heated flooring down in the process. It about doubled the cost of the project however now I have a floor gas furnace. The heat never rises to the ceiling and gets wasted. There are no hot and chilly spots. It is much more energy efficient so I can set the control component a little lower. What is also nice is that the gas furnace is hidden under the floorboards; Nobody is getting burned on it and there are no eye sores in the home. When our main Heating and A/C plan breaks I am only going to worry about an cooling system. That way I can have the best of both worlds. Another replace I did was get the air duct cleaned, add a new control component and an media air cleaner to our return ducts. All of these Heating and A/C additions were rough however totally worth it at the end of the day. The house feels cleaner and looks more modern. I also was able to transport into a perfectly cleaned house after I was all done.
