MD Repair - Do not use them! We had a new furnace/air conditioning installed in June of 09 and they have been out here 4 times for repairs. They do not care about you once they have your money. There is no excuse that when you spend over $9000. for a product that anyone should have to come out 4 times in 20 months for repairs. They act like you are bothering them when you call. Their business cards offer 24 hour emergency service, but they do not provide it. Just didn't want anybody to go through what we did.
