Best Heating Tune Ups in Baltimore MD

Had an estimate for electrical upgrade and he was fantastic explaining everything and was very professional

I will never use horizon again. They wanted to charge me 400.00 dollars for a 30.00 part. Plus the 98.00 for coming out. Once I spoke with the technician about the outrageous cost for the part, he asked what I thought I should be paying. As I told him I have no problem paying but it should be a fair and honest price.My bill went from $500.00 to 200.00. How many more people are they ripping off?
