Are you happy with your Central A/C? Who makes it?

Wow 38 years!! Mine is about 15-16 years and the tech said we are on borrowed time.  I bet your electric bill will go down with a new unit.

We have a Trane as well. It is 27 years old.

Ours isn't that old but I have a bad feeling about it. I have gotten a bid for a new one, but it is hard to figure out what we need. I'm frugal, but I really want my house to be cooler.

We just replaced our A/C unit yesterday. It was 15+ years old and definitely on it's last leg. It couldn't cool the house lower than 80 degrees. Our bedroom was the worst. It was the hottest in the house. I was against spending so much money on something we only use a few months per year. But dh had too many positive reasons to invest.

He got a few quotes from some companies and we ended up going with who his co-workers referred. Our house is 2500 sq ft. We went with an American Standard unit. It's a bit quieter than what we had and definitely more powerful. Now our bedroom is one of the coldest!

My advice is to shop around before spending this big chunk of change. Do research on unit sizes and differences in types and brands. Familiarize yourself with how it works so you can ask important questions. Dh asked some tough questions and some obvious ones and the way the salesmen answered them made a big difference in our decision making.

Same size as our house and same problem with one side cooler than the other.  When you have the unit replaced, have them evaluate the number and placement of air returns.  They added 2 on the hot side of the house and it has made a world of difference!  We also added a couple more vents due to changing the floor plan.  Surprisingly, it didn't add much to the overall cost.

We installed a Trane 3 years ago and have been very pleased with it.  No problems and it keeps the house cold.  Prior to that we had a Lennox for about 15 years.  While it did cool, we had many problems starting about 1 year into it.  The Trane has been better in that respect.

I can get all of you info from a trusted pro in the business tomorrow.  It's too late for me to get the info from them tonight.

Oh I'm sure it will. And it will be quieter and just so much nicer. My place is very small so the quote I got for a new system of central heat and air with install was only $4200. Very, very reasonable. I just have to have $4200.

We just got a Lennox installed this summer. It's been wonderful.

I think ours was installed in 1986, so 30 years old. We only have AC on the 1st floor. It works great, I'm not sure of the brand. Upstairs we use window units in the bedrooms. We have original radiant heat. The joys of an old house (1922).

I think ours is Trane as well. We had to replace our old one after 8 years. The builder didn't put a large enough one in our house either, or enough vents. I'm so much happier with our new one and our house can keep up with the heat. It was expensive, but worth it. It'd better last.

The thermostat they installed didn't last though and I think they installed it incorrectly. When we replaced it, our bill went way down.

Oh yes, very quiet and works like a charm, I have never had any problems with it.

We have a 1600 sq foot home in Florida and had to have our unit replaced 18 months ago.

We used a local guy and he put in a Goodman 4 ton unit....which is the same size we had. The one that came with the house when we purchased it was 21 years old at that time.

Our installer told us that a lot of people do not put the right size unit for their sq footage with shortens the life of the unit.

He recommended 1 ton per 400-500 sq foot of space being cooled/heated.

We have no complaints with the Goodman unit or their service, in fact they come out annually to service it which was part of their package when you buy from them.

Edited to add that our power bill has been reduced by about 40% since we installed this new unit too, so it's a win, win all around...and it's also very quiet....the only time you can hear it is if your are outside near the unit when it kicks on.
