I am extremely impressed with this company. My wall heater wasn’t working and it has been so freaked cold!! I requested a quote conveniently on the Yelp app and this company respond quickly and was available to come out today between 5 pm-7 pm. Not only was Mike early but he fixed our issue at no cost to us. My 5-month-old pit bull accidentally pulled some wires out of my wall heater lol regardless Mike immediately found the issue and fixed it. I now know who to call to help me in the future if another issue occurs. Thanks, Comfort Air Conditioning and Heating. I highly recommend this company in San Diego!!
