"?I couldn't be happier with my new water heater installation. The team was professional, punctual, and incredibly efficient. They took the time to explain the new unit's features and ensured the workspace was spotless before leaving. ?It?s a relief to have hot water back with zero stress. If you need a reliable install, I highly recommend Expedition!"

"Keith did a great job. Very professional, right on time, got the job done fast and done right at a very competitive price. Took the time after installation to show me the job and explain the features of the water heater, and also gave me information on how to properly maintain the unit and other services he offers. I would strongly recommend anyone consider Keith's services."

"They did a wonderful job. They explained everything step by step. They had to remove an old boiler to properly install water heater. They ran new lines and insulation."

"Jake answered the phone when I called the first time, he came out to assess what was needed, he provided the estimate, and then proceeded to do the work - all the same day! He replaced our 15 yr old water heater, including a new pressure expansion tank, piping, fittings and valves. The price was very fair and the work was very good. Jake was friendly, informative, and professional, we will use him again for future work."

"Walley's called me back within an hour of placing the request for a quote. It turned out they had someone finishing a job in my neighborhood and was willing to come by and take a look at the situation. Bryan, the technician, was very professional, courteous, and friendly. It was late afternoon when he came by, and he gave the office the information for a quote, and agreed to stay that evening until the job was done. He arranged for another technician to bring a replacement water heater over so he could continue the prep work while waiting for the new heater. There was no wasted time on the job - Bryan stayed at it until about 9:00 pm when he finished explaining to me how to adjust the water temperature after it heated up. He did beautiful work and cleaned up afterward even though I told him I would take care of it. I would absolutely hire Walley's again for plumbing, heating or air conditioning work!"

"Sila Heating and Air Conditioning is the only service I found that can service my Buderus oil burner. John was the tech this time and he did an excellent job of taking care of the burner and then explaining the problem that arose with my chimney liner. Since I didn't have heat or hot water until the liner was fixed, I had to use a company I didn't know as an emergency repair. I was able to speak with their tech using the information provided by John and therefore felt comfortable with the costly repair. John even came back after his last call to turn the burner back on. I have the warranty on my burner so I pay a discounted price and have the coverage if I need it."
