The service request was for you to come out and see why both units are running louder than usual. Juan found nothing wrong that would contribute to the louder vent noise but did discover that something called a capacitor in the attack was low, so he replaced them. The A/C still cools, but the blower now no longer shuts off and has been running since Juan left. This Phillip person, told us he's been doing this for 45 years and he knows that's our units have always done this and we're trying to get you to perform a service that was not reported and we would need to open two more service requests to fix what wasn't wrong before. Phillip would not listen to me and would continually talk over me. This was never an issue before. This is something your company caused. We do not want new A/C units, and again, our units are both still running. I will call the warranty company, but will also report your company and whatever else I need to do to get this resolved. Phillip said because we've only lived here for 2 years, we just never noticed that it never shut off, which is just plain ridiculous. I am beyond frustrated...

We had a couple of companies come out, but Cosmo's Heating and Air Conditioning was the one we went with, and I'm glad we did. From start to finish, the experience was great!! Communication was a plus... they stayed in touch throughout the job, showed up when expected, and even worked around our busy schedule. Ben was professional, respectful, and took real pride in his work. He made sure everything was done right and cleaned up thoroughly, inside and out, before leaving. It's not always easy to find a company that delivers both quality work and honesty, but Ben and his team did just that. If you want the job done right without the runaround and stress, they're a solid choice.

He had to get some parts and come back, and we replaced the motor on our AC. A lot of companies would probably have tried to just install a whole new unit, but Chris is always trying to fix what we have. I really trust him and his advice. He has always been more than fair price, sometimes I feel like we underpay him! He explains everything in-depth before he does it and is willing to do the most to save the unit you have. If you have some company trying to tell you that you need a new unit, have Chris come out before you invest thousands. You won't regret it!

First, I saved a ton of money, I got four estimates and Roberts AC was absolutely the best by far. I only got estimates from places rated five stars on yelp. He was also willing to come out and do the estimate in the evening, and his crew completed the work on a Saturday, which was awesome. The Icing, maybe the whole cake, was how much care they showed for my garage. I have a bunch of projects out there, and they could have just installed the unit and called it a day. Nope. They tented everything *LOVINGLY* with plastic. My garage was immaculate when they were done. It looked like a Dexter room out there. I have had other installers out there doing drywall and electrical and ended up with drywall dust all over everything. Not Roberts! I wanted a Unit that would get my partially insulated two car garage to 72 degrees in a timely fashion, and told Robert this. He said not only would this not be a problem, but the garage would be the nicest room in the house. I assumed this was just showmanship salesman BS. MY GARAGE HAS THE BEST CLIMATE IN THE HOUSE.
