Minor Issues

We have had our two units for nearly twelve years. And in all that time, We have only had very few minor issues. One was just that a bug got into the wiring. They came and cleaned it out and it started working just fine.

Going Strong

It’s been a very reliable system that I use for heat and air conditioning and has been going strong for a lot of years and I’ve only had one repair on it. I would recommend in putting a system in your home as I’ve had good luck with it.

No Problems

Okay, I read a lot of the posts on this site. I have a Carrier and I have no problems. From reading the posts there is one thing that a lot of people overlooked that can be the cause of most of these problems. The duct work, if it is under-sized, broken, leaking can cause all of these problems. It may not be the system at all. Look at the duct work. In my area 90 percent of the duct work is way under-sized.
