I could not get ahold of my previous air conditioner guy after 3 tries (guess they were busy), so called Titan since they were listed as working on ductless air conditioners. Should have waited for first company to come!!! I will say Titan responded quickly. Previously, I needed coolant added and it would run fine for a year. So, that was what I wanted done. He tried repeatedly to convince me to "fix" the unit, since he felt there were leaks in the system. Long story short, he charged me 98.00 for 15 minute service call and 75.00 a pound for the coolant, compared to $35.00 May heating and air charged me exactly one year ago. He said I needed 3 pounds, when last year it was just one. I'm not saying he was wrong about the amount I needed, as that could have changed from last year, but by then I was already feeling ripped off. So including labor, price was $358.00 versus $165.00 last year. Will not be calling them again.
