One Guy Plus II Heating & Cooling

We had him put in a new furance two years ago. Then last summer I had to call him back out cause of our a/c unit he had to disconnect to put furance in wasn't working. Then he charged me for that cause he had to recharge my a/c. Then this summer my a/c wasn't working again. So I called out another company and they told me whoever put my furance in is the one who damanged my a/c coil. So $2545 later I have to have a new unit put in. I wouldn't ever recommend this company. I have xalled him and left messages and he hasn't returned my call at all.
