“We’ve had MPS out a couple of times now, and each time they’ve been great to work with. The first time was during the summer when one of our smaller units needed to be replaced. They were quick to get this done and it’s been running great since. They also came out to work on our chiller system recently and again the whole process was smooth even though we had another company try and fail to fix our problem. Their team is always professional, polite, and easy to talk to. They explain what’s going on without making it confusing. Since their last visit, the building has stayed comfortable and we haven’t had any more issues. We’re really happy with their service and would definitely recommend them to anyone needing help with chillers or HVAC systems.”
