Gary Markgraf is a great guy to know when you need advice on furnace and air. He came out at our convenience, and gave a very fair quote. So, we had him install a new furnace and air conditioning unit. He did a great job and we would highly recommend him.

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.

We have been customers of Markgraf Mechanical for over eight years and have always been very pleased with their services. We have had them install an air exchanger, a dryer booster fan and a programmable thermostat. Additionally, we have had them service our furnace and our air conditioner. In all cases they have provided quality workmanship and fast friendly service.
