My 90 yr old uncles air conditioner went bad today. I called the after hours line.at 5:00and told them the issue. Wonderful Kevin was there by 5:30! He checked unit completely and even had to go back to shop for a part but problem was resolved by 6:45!. I am so grateful for such service! I also learned how to avoid the problem in the future. Thank you so much!

If you want to pay a few hundred dollars to still not have heat, this is your place! If you want your money to be spent getting things done, go somewhere else. Had issues with my furnace over the winter. Called to have them out to look at it. The guy was there about 15 minutes and just filled the water up a bit and left. Within a few hours our heat was out again. Had to call someone else to come and actually fix it.

They still charged me almost $200 for it. I called many times and left a voicemail about it. My husband finally called again and they said there is nothing they can do about the charges because "they didn't know about it" even though I had been trying to contact them.

I tried calling 3 businesses when my heat went out in frigid weather. Robert Gibb & Sons was the only one that responded. Work was explained along with the cost. Rob was my service person and was awesome! Service: Repair HVAC

Do you want to have them perform a service on your house or business and then five months later have them perform the same service? If you answered yes then hire this business! If you answered no then I would not recommend you call them. I had them come to my house because I had water in my basement and they fixed it and said you might have to have this done every year.

I said okay. Five months later. There is water in my basement. So they fixed it the first time why wouldn't they fix it again and they did fix it again however it was the same problem. So did they not completely fix it the first time? What's the issue? They don't care. I guess they're right I don't have water in my basement right now. but I know who I won't be calling in five months. This company.

Highly recommend! I live out of town and my furnace decided to stop working this evening. Cody tried to troubleshoot over the phone, but came right out when he realized I likely needed new parts. Would give 10 stars if I could, I'm so happy to have heat again. Honestly didn't even take 3hrs to go from calling them to having heat. Most places wouldn't even come out here.

They responded quickly after I called and told them my furnace was leaking water. Turned out to be a torn gasket that they damaged during a annual check up. They covered the service call and the repair under warranty. Very satisfied with their service. Service: Heating system maintenance

We love Robert Gibb & Sons for any plumbing needs. Their team is personable, skilled, and willing to take the extra step to provide education on plumbing systems. I'll always call them in the future!

Excellent work - installed new kitchen faucet. Arrived earlier than expected so I didn't have the sink cabinet cleaned out yet. No complaints from the plumber (and I'm sorry, I don't recall his name, but he was excellent! Very professional, friendly, knew his stuff!), he just got busy and handed me the items to stash - and he still finished in less than an hour!

I needed our gas fireplace looked at -- we hadn't used it in a while and were in the process of selling our house, when the real estate home insprctor indicated several issues -- so I called around. And around. And around. Home and Hearth where we'd originally bought it was very unhelpful, Laney's, Home Heating and Plumbing and others either couldn't do it or told me I'd have to wait a month or more before someone could come out to look at it.

In desperation I called Robert Gibb even though I didn't think they handled fireplaces. Two days later a great guy came out and thoroughly inspected everything and took care of all issues on the spot! He was also very friendly and fastidious, leaning the area cleaner than he found it. Then the bill was only about half the amount I had expected to be charged! I can't say enough about this great experience except. How Fargo of You! Or maybe: How Robert Gibb of You!

In 2019 we spent $3500 for Robert Gibb & Sons to install an Air Conditioning unit. We picked out a unit & upon installation we were told they gave us an "upgrade" because what we chose was not available. We have been calling the office repeatedly since the installation to get a copy of our purchase receipt, the warranty we also purchased & the owner's manual.

To this day we keep hearing promises but have received nothing. On 5/20/21 we had them come out to look at the unit as it was not cooling properly. We were informed that we needed to spray the unit with water about 2x a year, but very carefully or we would bend the delicate "fins" & void our warranty. How were we supposed to know that? Then we received a bill for $140! How dare they

None of the employees were wearing mask and they're all liars. They tell you one price and then hit you with another at the end. Would not use them ever again.
