M&K Heating and Cooling Services are great, I have only good things to say about them. I've been using their company for awhile and continue to use them because they do everything with professionalism and care. They are always on time, showing up when they're scheduled and do the job they're hired to do whether it's maintenance or repair of my HVAC systems. MK have been very fair to me, they never try to sell me junk that I don't need, or charge me too much for the work.
