We are so happy to have learned about local contractor, Markgraf Mechanical, Inc. a couple of years ago when we had an emergency. Gary was prompt with his response, checked our heating, air conditioning and water heater and repaired what was necessary. He has been our 'guy' ever since. Gary & Tammy are so nice to work with; listen to us and advise what's needed.

Markgraf Mechanical installed and has maintained my high efficiency natural gas boiler. This was installed in 2004 and is still saving me money! It does in floor heating for my kitchen and lower level family room, also an 8' cast iron radiant heat for the basement, and my hot water! He also has installed an A/C unit which is now over 20 years old. They stand behind their work! I highly recommend their services!
