"I had an issue with my furnace, so I requested help through Angi. Miki called me within 10 min and offered to come straight out to my house to diagnose the problem. After stopping at the store to pickup a new furnace filter for me, he showed up and got to work. I was very impressed with how fast he addressed the problem and fixed it. He then went on and showed me the type of filters to buy and what to stay away from. My furnace is very old and as a result will need to be replaced sometime in the next couple years. So when I change the filter he showed me what to look for so I know when the furnace needs to be replaced. I really liked this guy he came out right away, fixed furnace, offered me free professional advice and charged me next to nothing. He is very honest and reliable. I would and will highly recommend to anyone who seeks a heating/AC professional to work on their project!"
