Description of Work: We have a boiler and radiant heat. Some of the thermostat controlled zone valves were not working properly, causing the house to drastically vary from hot to cold from day to day. They got everything working perfectly, reconfigured the thermostats (they were never programmed for radiant heat), and flushed the lines the ensure no air was present (which reduces efficiency).

Had to redo all of the ductwork that my contractor had done during a basement remodel. That contractor's work was so poor that under threat of legal recourse, he hired Markgraf to reduct everything. They were very professional, very thorough and righted a big wrong.
Description of Work: Ductwork in a basement ceiling, borrowing from 1st and 2nd floor existing ductwork.

They had installed our air conditioning unit, that's why we had called them back. Our unit wasn't working, they needed to fix a small hole in one of the coils. I thought that they did a good job when they got here. Sometimes they can be a little slow getting out here but once they do come they handle the problem well.
Description of Work: I last used Markgraf's Heating & Air Conditioning about a month ago.

After calling Markgraf's, a salesman came out to give me an estimate. I called the company at least 4 times afterwards to ask some questions before I contracted the job. A month or two went by and no one EVER called me back even though each time the receptionist told me someone would call me back by the end of the business day. I waited another couple months and decided to try them again. This time I talked to the owner of the company who sent out someone else to reestimate the job (since the first one was not thorough). He told me I would have the proposal in a couple days. I waited over a month and then called to ask where it was. I then receive an proposal which was the least professional I have ever seen. I tried to call AGAIN to go over it and AGAIN no one EVER returned the call. I would highly recommend NOT using Markgraf's.
Description of Work: I called Markgraf's for a proposal to replace my entire HVAC system.

The experiences went well---we have many different types of heating and ac units(from steam to water to electric) and they do a great job maintaining all of them.
Description of Work: We have used Markgrafs for the past 4 years to install 2 airconditioning units and 3 heating units as we have an old house with many different systems. They also do our biannual maintenance. They are extremely competent and are always prompt and professional. We would highly recommend.

We have used Markgraf often, so they are familiar with our layout. Dave was here about an hour, working on two furnaces in the basement and one in the attic. They set the humidity to 35% and checked all cycles. They always arrive promptly and they warranty their work.
Description of Work: Annual Heating maintenance and cleaning for 3 furnaces ($210), 3 humidifiers + #35 pads ($105); changed filters (20 x 26 x 5) ($135)

When our existing furnace gave out on one of the coldest days of the year I called three companies for estimates to repair and/or replace what we had. Markgraf came recommended from a co-worker. All three recommended the same equipment and Markgraf was $2000 lower than the highest quote, $1000 less than the middle quote. Because they were recommended by someone we knew we happily took the least expensive route. The representative was helpful, knowledgeable and spent his time answering all of my questions. (I'm a tough customer because I work in the commercial building controls field and know more about how buildings are controlled). Because of the amount of snow on the ground, we agreed to do the furnace work immediately but hold off on the A/C work until spring. They were good about not charging me for the A/C work until it was completed. Both installations were scheduled and handled very professionally. Time estimates were good and all of the work was done and cleaned up appropriately. I'm very happy with this company.
Description of Work: Replaced furnace and A/C.
