"This is the 2nd or 3rd time that we used Jimmy and couldn't have been more pleased. My house felt like a sauna and we were desperate for Jimmy to come over. He was extremely busy however he found time to stop by. We were told that we needed a new unit and by 3:30 the following day, we had a new unit installed. Can't get better service than that!!!"

"GAC came to our house, and in these trying times, face masks, gloves to evaluate our home and provide three options. And their proposal was the best we saw since we sought more than one. Their team came on time, and removed old system. Installed new system, and re routed system lines better than previous installer at no cost. Even insulated exterior lines and added additional protection for them. Leveled the compressor. And installed a better humidifier. All while in these trying times? Social distancing was maintained even when they walked me through the set up my Nest Thermostat, and system training. Face masks and gloves. Work area was clean and neat after they were done. We are so pleased with how GAC handled our job. Oh, and all the extra work they did? No additional cost for me. Part of the contract they offered me."

"I had a plumbing issue that I thought would turn into a major headache, but Mahon Plumbing made the whole process smooth and stress-free. They arrived on time, quickly diagnosed the problem, and had it fixed before I could even make a second cup of coffee. They were professional, knowledgeable, and even gave me a few tips to avoid future issues. The pricing was fair, and there were no surprises on the bill—just great service from start to finish. If you need a plumber who knows what they’re doing and won’t leave you with a mess, I highly recommend Mahon Plumbing. I’ll definitely call them again for any future plumbing needs!"

"On time, in fact earlier than expected. Courteous technicians. Provided options for repair or replacement and was forthcoming about what he saw. Recommended a highly reviewed water heater. All around excellent."

"Markool was super professional, kind, and skillful. A few things really stood out. 1) He did a furnace flue piper install that he could have charged us much more for if he had wanted to take advantage of us - but he was honest and we paid less than we feared. He also went the extra mile helping my wife and I through a warranty claim with the furnace company so that we did not have to pay extra part costs. It was an unexpected need, but he was prepared with the part and worked with the manufacturer to get us covered. He was even able to better a previous repair. 2) On a home humidifier install, he made himself available on short notice, took time to answer our questions, and then showed us how to maintain the equipment ourselves so we wouldn't need to shelve out more for additional contracting work - even from him. Grateful!"

"Great! I have used Furr Plumbing many times so I was not surprised that they quickly located and fixed the problem however I was surprised when I received a NO CHARGE INVOICE! Thank you Furr Plumbing!"

"Easy to communicate with, very efficient, timely, and the most affordable for great work and quality items. Rob installed and removed a water heater, replaced two faucets, and replaced rusted bolts and handle on the two toilets. Will be keeping Rob as a trusted plumber for any future jobs."

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

"Family Fire Service did a great job replacing my water heater! They were quick, attentive, and thorough. Excellent work!"
