"Muirfield did a great job at a reasonable price. The Tech was thorough and explained the issue in detail and although I had to order a special part for my Hydroair system, they got it in and installed it ahead of schedule. I’m 100% happy!"
Robert Canarri
"Fixed a complex problem on my Goodman Furnace. They stayed on it until they determined the problem and implement the fix. There is nothing more important than good service when you have issues with an HVAC system where its dependability is critical to your comfort. Nice going Muirfield!"
Steve Maislin
"Just installed central heating and ac. I highly recommend this company. They did excellent job under harsh condition (over 100 degree in the attic). Service crews are very nice answering all the questions and showing high quality of technical skills."
