I moved into my house about 15 years ago and the furnace had been in the house for at least another 10 years before that. Even though the furnace was old, it has always been reliable. For years, it was efficient and effective. I made sure to take good care of it to keep it up and running for as long as possible. I made sure I had an HVAC technician do an annual service check. I also did small maintenance and repairs myself, such as changing and cleaning air filters and limiting the number of times a year that I turned it on and off. However, it was inevitable that the furnace would eventually fail. Last week, the furnace began making some weird noises and the temperature in the house was dropping rapidly. I contacted my usual HVAC company, and they told me it would be best to replace the furnace. I decided I want to try a new heating method, but I’m not sure what will work best for me. I don’t think the gas furnace is the best option because it gets extremely hot to the touch and it can be dangerous. I’ve heard of gas furnaces leaking carbon monoxide into the air. While we’ve never had an issue with ours, I figure that it can’t hurt to try out some newer technology. I’ve considered radiant heated floors because they come with strong recommendations from anyone that has them. My only concern is that there is no paired air conditioning system to go along with radiant floors. I am thinking it would be best to get a unit installed that can regulate both heating and cooling in the house. Right now, I am leaning toward a split duct system, but I still need to do some more research.
