Last week I had a Buderus high-efficiency propane Heating system with Hot Water hookup installed in a house I rent to my Brother-In-Law. I had confidence in Mark Derix, the sales manager, from the moment I met him. His son, Mark Jr., and Dean were the installers and they both did a wonderful job installing the equipment and disposing of the old oil tank, leaving the place in a proper, orderly, clean, and workmanlike condition. We were both extremely pleased with the care they took of my house and property. We look forward to having Oehlert Brothers as our heating providers for many years to come. Sincerely, Dr. Paul C.

Markie and Kevin we’re replacing my chimney liner. They ran into a problem with the terra cotta liner. It had shifted and cracked over the decades we’ve lived in our house. They both went above and beyond when faced with this dilemma. The solution was probably the only one possible without incurring additional expense. But the solution was not an easy one. It turned out that the fix involved a “spearing” operation that required strength and stamina. Needless to say, a normal job was magnified. It required additional materials and probably three times the labor. Oehlert Brothers stood behind their original estimate. They analyzed the situation, made the best of a bad situation, and yet they still honored their stated cost. It is people like Markie, Kevin, and Mark Deris (sales manager) who have made Oehlert Brothers the company they are today. We’ve been an Oehlert customer for 45 years and have had them do everything for our house (obviously oil delivery, replacement of our air conditioner and heater, and other odd jobs ) for a reason!

I would recommend Oehlert for Heating and AC. They also check your chimney and do attic fan installs. I'm sure they do more. (See More)

I just wanted to say "thank you" to the employees and owner Steve Oehlert. From the emergency service call last week at 1:00 AM and the response from the technicians that handled our leaking oil tank to the technicians that came out for the install yesterday (Mike D. & Mark D.). They all did an excellent job, were truly professional, cleaned up great, and were courteous and nice to speak with. And please give an extra "thanks" to Mike D. as he really did an awesome installation yesterday!! Oehlert Brothers should be very proud to have such excellent employees working for them. Thank you!

Mark D. and Kevin D. were respectful, courteous and knowledgeable. They both took great pride in their work and are valuable assets to Oehlert Bros whose pricing was fair and quality of service is second to none. The company took the time to understand our needs and any concerns and then make quality recommendations to suit our needs and budget. I'll definitely be calling on them in the future. (See More)
