Great customer service. They were out in the afternoon servicing my account unit that wasn't…read moreworking. They diagnosed the problem and fixed what they thought was the problem. When I got home from work, the AC unit was still not working. I contacted them and the owner was at my house within 20 minutes. The problem was diagnosed and fixed. Upon packing up, he went and got the check my wife had written earlier in the day and told us because of the error, he was not charging us anything. We tried to argue that his time was valuable but he was hearing none of it and wouldn't accept anything for fixing our problem. I won't use anyone else from this point on. Honesty and integrity hard to find these days and when you run across them, you keep it close by.

This company is a joke! Our air conditioner stopped working so we called Valentine for an estimate…read morefor a full replacement.After spending a few minutes looking at the system, they proceeded to write a quote. For our relatively small, 3 bedroom house we were given a quote of $30,000!! After telling Valentine this is outrageous, they responded by saying the cost is so high because it includes their "premium service plan." On top of this outrageous quote, they tried to charge us $650 to come out for the estimate. We refused to pay. The technician then laughed and said "whoops, I think my math was wrong."We still ended up paying them $350 but it was worth it to get them out of our house. Had 2 other replacement estimates done by 2 other companies; both were less than $7,000. Not even sure if con artist is a strong enough term. This company is simply dishonest and will say anything to get as much money from you as they can. There are plenty of other HVAC services in the area. STAY AWAY FROM THIS ONE!

Let me start by saying that I have worked with Robinson Heating and Cooling for over forty years,…read morefor needs at my office and home. They also installed HVAC when I built a house. In 1986, Stuart Robinson came out on a cold January night. He got the emergency heat running until they could replace the unit. I have never had any issues or problems in the past. Recently, Jason came out for the annual Fall service. With his camera he located a crack (not a good thing in the heat exchanger) on the video. The initial reaction was to replace the furnace. So we had another bid and he inspected and he failed to find a crack in the heat exchanger. Obviously we were confused at this point. So we hired a third service company to evaluate the unit. Again they came back with a diagnosis of "no crack". I did not know what to do. Nate Robinson (Nate is a licensed Mechanical engineer. Not many service companies have such expertise.) volunteered to come out with the service technician and replace the heat exchanger. I was shown TWO cracks. I apologized immediately for casting doubt. TWO heat and air companies missed TWO cracks. Do not doubt Robinson Heat and Air. Call them You and your family and pets lives may depend on it. They put personal care first, while being right.

My mom is an elderly woman that lives alone and is disabled and has been without heating for a week. Robinson not only charged her a 95 dollar service fee, which okay I completely understand for coming out. Hooked up a new thermostat which are typically builders series junk, showed her that the heat was now working. Then told her it would be FOUR HUNDRED DOLLARS TO INSTALL. The irony it was already installed, when she said that was outrageous he uninstalled it and left. No heat, in December for an elderly disabled member of the community who has spent who whole life doing incredible things locally for those in need. This is the most ridiculous thing I've ever head and I've worked in the home improvement industry for 10 years. Middletown you have a choice of which small business you choose, Robinson heating and air does not care about their customers nor community. The icing on the cake was I spoke with whichever supervisor was on duty WHICH NEVER RETURNED MY CALL, and he told me a completely different price (300) and then basically said screw off and hung up. The two prices aren't even the same!

The annual service for my A/C was very thorough, and during the technician's visit, they checked…read morethe furnace and discovered a cracked heat exchanger that might have existed since the severe winter of 2025-26. I promptly arranged for repairs, as I occasionally use the furnace on cooler nights, even when daytime temperatures don't require it. Unfortunately, the first appointment was canceled at the last minute, and the second appointment couldn't be completed because the new heat exchanger arrived damaged, necessitating a reorder. Additionally, I was overcharged for cleaning the blower, which wasn't performed due to the heat exchanger issue. I'm still awaiting a refund and am uncertain about when the furnace repairs will be finished. This situation could have been managed more effectively, and I hope everything gets resolved soon. I will post an update when everything is completed as requested.
