Sorry but the one star review is absolutely wrong. Grimley plumbing is a 5 star experience. He came…read moreright away on at least three occasions for me and my mom's estate in the last year. He only came and did what was needed and was extremely reasonable pricing. I would recommend Grimley plumbing to anyone and everyone. And I wouldn't trust a review that didn't even use the services but 'a neighbor told him.' Five stars from me for service, explanation of the problem, and pricing. And like I said, I've used them several times for two different houses.

They could have told us we needed a new well pump, but they didn't because they are an honest group and walk in integrity! They also are HVAC certified and install heaters, central air and mini-splits. I will never need to find another heating and plumbing company again because these men have earned my respect and business and I know I can trust them! Thank you so much for being so efficient and going above and beyond when answering questions that had nothing to do with the well pump! Jeanne Brewer, Elverson, PA

On Sunday, 2/8/26 during the extreme cold spell we experienced an issue with one of the units. Seemed that maybe Comfort Pro was having an issue for on-call tech. Tech showed up and checked our unit, advising that it was functioning properly and did readjust the gas valve, and departed. I had another HVAC company respond to check the unit. He said he smelled gas and found that gas line from gas valve to the line leading to the burners was leaking. I took picture of the fluid bubbling up after he sprayed it. Tech told me that the leak could have caused a terrible fire mishap, especially next to the burners. He corrected the issue and the furnace is presently back up to proper heating condition. He said the burners may not have been getting enough gas since it was leaking. We will be calling Comfort Pro on Monday! Should have techs better trained for these situations.
