Things are going well so far. I haven’t had any trouble with the Ruud AC
Things are going well so far. I haven’t had any trouble with the Ruud AC I bought. I got it 5 months ago to replace the old one which couldn’t cool the house anymore. Thanks to Ruud and a nice dealer here, I can enjoy the comfort of my home.

Hurray for Ruud. I’m so happy this turned out great. I was skeptical about replacing my air conditioner because the online reviews gave me the impression that there is nothing really worth the trouble out there. I got this Ruud because a friend of mine reassured me of its excellent services. For 7 months now the unit hasn’t given me any problems. Only had to fix it once and that was covered by the warranty.

The temperatures can really go high in the summer days. You can’t imagine my frustration when my AC broke last summer. For about 2 weeks we had to go without any air conditioning. I was in a rush to get the problem fixed so I got this Ruud but I didn’t know much about the unit. Finally, the problem was solved but then I wasn’t sure the unit would hold up without breaking down. So far so good, haven’t had to do anything except routine maintenance.

We have had the same ac unit for the last 18 years. After such a long time
We have had the same ac unit for the last 18 years. After such a long time a replacement is usually a better bargain than repairing. So we went ahead and bought this Ruud. I like how quiet it runs. It functions perfectly and does take much to run so the utility bill is low. This is what good manufacturing is all about.

Features that make an air conditioner perform well and last long are in eac
Features that make an air conditioner perform well and last long are in each unit that Ruud makes, no matter the level. Quality matters to Ruud, so every system has optimized access ports for servicing, powder coated paint and rust-resistant screws. They also have an excellent SEER rating, and no unit is below 15.5.
