Have new HVAC and Plumbing contracts with Sherman. Vincent and Brian and John came today and reviewed everything and did not try to sell me anything. They clearly wanted to save me $$$. I switched to Sherman because I learned that their techs do not work on sales commissions. They did everything great and did not try to sell me anything! Rosie worked efficiently with me to schedule visits. I am so glad that I switched to Sherman. read more

Terrible and irresponsible service. Asked to see 2 units that stopped working, they looked at one and had to call again for the second, charged 2 emergency visits for $450. Then they send me a bill for another visit for $579 and a proposed replacement of the condenser coil for over $2,000. Unnecessary! Another company repaired a small leak near copper ending for under $100. Looks like Sherman Tech had no idea what to do. Of course, never communicated with the owner. They just sending us bills! We terminated the contract, and hope no one gets stuck with this group of expensive and unreliable service. Good luck! read more

Been using them for 15 years and they have just gone down hill! Called about problem with AC unit June 2nd that they installed 11 years ago, took them 2 weeks to look at it charged me $350 to come out and tell me it was dead. We authorized them to repair or replace for just under $4k 2 weeks go by and I have to call to find out whats up, only to tell me rebuild kit parts were on back order. I suggested we just replace the outside unit and I got oh it will be a miss match, then follow up next day saying parts had shipped that day (June 31) and due to 4th holiday they would not get till next week. OK parts come in and they install and find (Oh we need a new outside fan motor another $650), but they will get it next day and if it comes in early we have it done same day (Thursday) otherwise Friday. And of course it's Sat now and no one came or called. So now my rental unit has been without AC in heat of summer for 6 weeks, and given Sherman's initial delay of 2 weeks to just look at it. Clients are upset that I tell them work will be done by time they check in only to find not done. I look bad, get bad reviews so I am sharing my pain. It is time to find a reliable vendor!! Not these guys read more

Charles was VERY thorough and VERY helpful! Answered all my questions and showed me some maintenance techniques! He was fantastic!!

We have used Sherman for years. Christos was great. Solved our plumbing problem promptly at a reasonable cost.

Iam writing to express my disappointment with Sherman. Have used this company for years and needed a new HVAC system. The price at 17,000$ was so overpriced! So disappointed in the direction this company has taken. read more

I am writing to express my disappointment in the service received from George Sherman Plumbing. I own a condo in Dewey Beach, De. My condo board requested a plumber check the crawlspace under my building for a possible leak. The condo board paid Sherman $571 for a repair to a leaking tub drain that allegedly belonged to my unit. Then billed my account for reimbursement. For 4 months we have tried to locate the origins of the leak by speaking with the Sherman plumber, office staff and the field supervisor. We have received 4 amended invoices and one amended "work order" from Sherman as well as emails from our association board that has changed what was repaired (tub drain or faucet), where it was repaired (in the unit or the crawl space) and in which of our 2 bathrooms the leak supposedly originated. The plumber took a picture of the repair in the crawl space that showed white PCV pipes. Both of our bathrooms have old, black metal pipes. On January 13, 2023 my husband dropped light-sticks from our tub pipes (through wall hatches) into the crawlspace to provide a reference point for the location of our 2 tubs to assist finding the PVC piping of the repair. (It had already been stablished we did not have PVC pipes as shown in the picture.) Upon entering the crawlspace with my husband, the plumber went straight to the light-stick of our guest bathroom (which we had identified), took a NEW picture and said he had originally taken the wrong picture of the repair (white PVC vs metal pipes?) It should also be noted that the latest invoice states the repair was to the master bath while this "new" picture taken by the plumber was of the guest bath plumbing. I believe Sherman Plumbing has played a "bait and switch" game for 4 months and has lost my trust and any credibility in identifying the leaking pipe. While the bill was reduced by $149 due to their "confusion", I believe the bill should be waived by Sherman. My husband has made 4 trips from Virginia to Delaware and back to inspect the latest so-called location of the leak, each time proving the plumber wrong. Our condo association has used Sherman Plumbing exclusively for winterization, boiler maintenance, and plumbing repairs for years. Based on this lengthy relationship with the company, numerous emails, phone conversations, changing photos and modified invoices from George Sherman the charge of $422 should have been removed. I would not recommend George Sherman Plumbing based on their lack of integrity, professionalism, the questionable quality of their work and poor documentation. read more

I have used George Sherman Corp. for many years. Because of the new EPA Freon requirements, I needed a new HVAC system. Elias, the project manager, arranged for the installation flawlessly. Not only was the installation immediate, the tech, Eric, who did the installation, was simply outstanding. He was thorough and efficient with a patient and friendly demeanor but, other than a brand new system that was installed in less than 48 hours, you would never know he was here. It was a huge undertaking that I was resolved to have to clean up afterward, but Eric belied my expectation by cleaning so thoroughly that it only added to my complete satisfaction. Thank you Eric, Elias and George Sherman Corp. Julianne Waesche Rehoboth Beach read more

I'd give a zero if I could. Came out, found no leak, and still charged a repair fee. They did nothing!

Always had a good experience with this company. Especially with one of their employees Skip always polite shows up on time cleans up after his work and thank you for your business. read more

Bad experience with one plumber from Sherman. Didn't wear shoe coverings so he tracked wet dirt onto my floors. He clearly did not want to be there. The bathroom faucet was not centered, the left handle was loose and a portion of the black gasket is showing. So buyer beware when it comes to Sherman! read more

Christmas weekend, pipes froze in my mobile home. Woke up Christmas Eve morning to no water. Called, they came, spent about hour and half defrosting my pipes. Luckily the pipes did not burst. They charges me almost $1400.00. Yes, I could have declined the service, but I felt like I was in a bind. I really feel like I was taken advantage of. After it was fixed, I called out of curiosity, five other plumbers companies. They would have charged me about half of what these guys charged me. NEVER AGAIN! And I will not recommend at all. BTW, they don't charge an hourly rate like the others. read more

Had a new HVAC system installed and I could not be happier with the results. Not only were the installers polite, but, they were efficient and quick. Ran into a problem with a circuit breaker from the old system that was partially melted. Thankfully, the installers found it and they took a picture to make sure I was informed regarding the problem. The new Honeywell thermostat can be controlled through WiFi, a great plus for anyone with a second home! Sherman, thanks for the great job! read more

Today we were 1st-time customers. Because it's plumbing, we're hoping not to need the service often, but will not hesitate to call if there is need. The receptionist was very pleasant at before 8 a.m., the service person (a very cordial gentleman) arrived within minutes, and our problem was quickly corrected at a reasonable cost. We're happy with this company. read more

Professional from start to finish -- and we presented them with some problems that weren't immediately evident. They were knowledgeable and did great work. read more

I had some pipes freeze up during the recent cold snap. Sherman was the only company I called that could get out to see me the same day. They arrived within about 90 minutes, and had the problem solved quickly. Charged me for an hour, which included travel time. I really didn't have any issues with the work or the charge for the work. I would use them again. read more

I was billed $357 for a after hours service call that nothing was repaired and Shermans diagnosis was incorrect. I asked why wasn't the issue ( something wrong with heat system making an odor of gas,) wasnt fixed, and was told that I called the wrong entity of shermans and that I needed to call the repair department. When I asked who came out, they said it was only to check for leaks. Duh, that's stating the obvious. The "tech" said that it was a leaky valve. The next day I had an HVAC tech come out to address the issue. Because there was still an odor in the house, the first thing he said was "this isn't a raw propane gas odor, it's an exhaust odor", he checked the exhaust pipe for the furnace which ran under the house in the crawl space and exited out through the foundation under our back porch. He immediately saw the pipe had separated at a coupling and determined that was the source of the burnt propane gas odor. So he reglued the coupling, checked the other connections and all was repaired, no more problems. There were no problems with the gas valve at the furnace as reported by the Sherman's leak testers. After going back and forth with shermans they adjusted the bill to $200 and wouldn't take any responsibility for their lack of and incorrect service, when I offered $100 they said they would terminate my propane service. IS THIS A COMPANY THAT YOU WOULD WANT TO BUSINESS WITH? THEY TAKE NO RESPONSIBILITY FOR THEIR MISTAKES AND PASS THE CHARGES ONTO THEIR CUSTOMERS! read more
