Hot2Cold is an awesome company. The person they sent to check on our system named James was supposed to give us an estimate for our AC duct cleaning which I thought we needed because some rooms were much hotter than others. James checked our entire system and found that it settings the installation company left for our units are not proper for our house. He put proper settings and adjusted all of the vents in the house which made it feel much better. On top of that he didn’t charge us anything! I haven’t seen this level of honesty and professionalism in a long time. Recommend this company to anyone who needs their AC serviced.
