We called these guys after our A/C stopped cooling, and I saw a recommendation for them on our local NextDoor website. We had a system that was 11 years old, but aside from being a Bryant (bottom-end of Carrier) was otherwise working except that it gradually stopped blowing cold air.I called them at 7:30 in the morning, and they promised someone would be there between 4 and 6pm. Joe called me to say he was running a bit late, but they still showed up within the window they gave me.They told me that they don't charge a different price for different days of the week or times of the day. A service call is a service call and I could have called them the evening before.Turned out to be a coolant leak, and rather than spend lots of time trying to figure out which coil was leaking, and then spend nearly half of what a new system would cost - we invited them to give us a quote. In the meantime, they put in enough refrigerant to get our system cooling again, and told us to call if we noticed it starting to be ineffective again.They gave us an extremely reasonable quote for a 4-ton replacement system, with an upgrade on equipment from Bryant to Rheem (Ruud).They showed up when they said they would, and in about 4 hours we had a brand new system up and cooling the house.They cleaned up every mess they made so that you couldn't tell they had been there.This is a two-man company that seems to stand by their work. They are honest and forthright and most importantly in today's world, their word appears to be their bond. If you aren't happy, they aren't happy.I've used one of the big names in the area and these guys beat the pants off of them for service.Chuck and Joe will fix your system and charge you a fair price and they will do it today, or at the latest, tomorrow. If they can't fix it, they will quote you the best possible replacement they can give you at the fairest price they can offer. They will show up when they said they will, and they'll do an honest days work for an honest dollar.You can't get any better than that.If you have HVAC issues. Call these guys.

Great company, I would never call any of the bigger named companies when these guys give personalized service. The owners of the company do the work so they have their reputations on the line. You won''t get an hourly worker who doesn't care about quality. Fast... fairly priced... got my job done without a long wait. Thanks!

Joe Grocki saves the day! ...We had a terrific experience with Joe Grocki as well - would highly recommend him!

We can’t recommend Joe from Cooling Dynamics Inc. enough. My husband had been using him for years on a previous house he owned. We called him to replace a 16 year old air conditioning system in our new home. Not only did Joe come in $2000 cheaper than a competitor, but is extremely honest, has excellent customer service and is quick/efficient. He came out to our house an hour after we called him, itemized the costs, explained our options and gave us an honest professional opinion on what we needed and what we didn’t. We had our new AC installed less than a week later and it looks so much cleaner than the old set up. He has saved us tons of money on our AC bill. We will continue to use him for maintenance on our. Thanks Joe!
