Window AC with replacement windows

18 years ago

I have been looking at replacement windows and had pretty much decided to go with the Pella replacements. When I was looking at the contract, it states that the windows are not designed to suppor air conditioners. Is this contract speak or would I truely have a problem using a window AC unit with a replacement window. Central AC isn't in the budget for a few years.

I am not sure what type of windows they are (are they double hung?) but I am guessing they are saying this because they have had issues with people damaging the windows with air conditioner units or they do not want to be held liable for units that fall out of a window.
I have never seen a window "Designed" to hold an AC unit they are designed to be good windows and nothing else. Just because you ac unit fits in the window perfectly doesn't mean they designed it for that reason (if you get my drift)
I believe they are saying the same thing as "add an AC unit at your own risk" The window won't be falling out of your house and you really can't break the glass because the glass is above the unit. The only think you could damage is the window frame where the unit rests.
However, some windows simply can't hold a unit so it depends on the type and style of window you are getting also.

The key word is "support". Windows are not designed to support an A/C unit. A wall mounted bracket and shelf should support the unit so that no weight is on the bottom sash.

I've been on service calls for some window companies and you wouldn't believe some of the haphazard designs some homeowners have come up with. Some were using the sash to support the total weight of the A/C unit. Not good!

If you mount the A/C unit according to unit directions, the window won't be supporting it.

Make sure that no condensation leaks on the sill. That will cause water damage and eventual rotting the sill and jambs.

as long as you can drain the condensation and adequately vent the discharge heat away.....it should work. Take a look at a ductless mini-split. Quiet, energy efficient, and a fairly easy install....but you still have to drain.

The proper way would be to measure the new windows to fit inside the existing frame. Sounds like you already ordered them to replace the whole frame though. Theres no way of getting around it you'll need to use the flange. If you have casings around the windows or vinyl siding it will be a pretty easy job.

Our home was built in 2001. We used Marvin Integrity windows throughout, except for three 12' wide patio sliders. Those are the high end Marvin. I would not buy Marvin windows again. We need to replace those sliders and I'm starting to look around. Friends of ours had a factory built home, called a Wick Home, made by a housing manufacturer in the '70's out of Mazomanie, WI. They had to replace windows and were getting all these very expensive bids because none of their windows were standard sizes. The wife is from Monroe, WI area, where there is an Amish community. They redid their windows with the Amish for a very large savings. She had to go and pick them up and take them home for 3 days, while they did the work but it was about 15,000$ cheaper than the other quotes they were getting. I'm also going to look into that. I haven't been happy with our windows. They get mold and peel paint along the inside casement frame, the big patio doors ice up in the winter along the bottom. The weatherstripping is brittle and breaks off in huge runs. The glass is cold in the winter and I don't think it reflects enough heat in the summer. We had 2 seals break. The Marvin rep came and they covered one, we are working on the other now. But we had to pay for the labor to uninstall the old one and put the new one in. It was at that point they learned that our patio fixed door was assembled backwards. Meaning the outside part of the glass was supposed to be inside. I just think all of this is enough to advise avoiding Marvin.

Sophie, the OP didn't say why he wanted to install a room air conditioner, and I think it's a stretch to assume it's because his home HVAC system isn't doing its job. Not everyone has or wants central air conditioning. As it happens, for example, I have 2 rooms with air conditioners in my house. That's intentional. One gets used regularly, the other only a few times per year. This setup works for me. And if someone (say, a guest in my home) tried to tell me that I should upgrade my HVAC system because my room air conditioners didn't meet his standards, he probably wouldn't get invited back. For the record, I agree that a mini-split would do the OP well. One of my air conditioners is a mini-split, and I like it. But it was outrageously expensive. I bit the bullet because I needed an especially quiet system. I hope installers have come to their senses since I had mine installed, but at the time, the installation cost over $1000. I had other quotations in the $2000 range. From what I could tell, they wanted about the same fee as they charged for a central air conditioner. In many other places I know of where mini-splits are popular -- Asia, South America, the Middle East, even Puerto Rico -- getting one installed usually costs around $100-300. I don't know about the EU.

The Pella contract is specific on the fact that you are liable for any damage created from an AC unit. There are a lot of companies that offer special sills that are made to support a window AC unit. I know Schuco offers them and also offer a small sash that goes in so you can lock it down to the AC unit. Kind of a mini sash to make your window look normal. I would ask your salesman if they offer a special sill for the AC window. See what he comes up with. Post back when you find out.
