Mill Air Mechanical came out today to fix my heater. My central heat and air went out over the summer; and tomorrow we are supposed to have freezing temperatures. I was worried I wasn't going to find a company that offers same day service. They had a fast response time and got here same day. He was very knowledgeable about my heater. Just by explaining a few things, he knew exactly what was wrong. He had my heat up in running within 5 minutes. I would most definitely recommend this company for any of your ac/furnace needs. Customer for life.

My a/c was on the fritz and it was 90 in my house. If that wasn't bad enough, I'm also going through menopause. Thankfully they were able to fix it quickly and offer me some much needed relief. They're knowledgeable, friendly, reasonable and family owned. FIVE stars all the way!

THEY ACTUALLY SHOWED UP WHEN THEY SAID THEY WOULD. i have had a terrible time getting anyone out to my house, they say they will, and they never do. When my AC went out a couple of weeks ago, I called them and she is amazing and he is awesome, I have an old AC unit, and since he came out, it actually gets cold in my house. They came out after hours, which was great for us, and took care of our AC problem. I also got set up on their yearly maintenance, I am so excited to have someone who actually wants our business and will take care of us. The experience was great, they are wonderful people, so

Mill Air Mechanical A/C And Heating LLC is the best! I was introduced to the company through my home warranty. Long story short, there was a lot of miscommunication and lack of communication on the part of my home warranty company. Mill Air was constantly in contact with them in order to move the process forward smoothly.
John was courteous, professional, and knowledgeable during the entire process. He told me what needed to be done and answered any questions I had for him.
Mill Air both displayed exemplary patience and professional behavior throughout the process. What should have been a 2 to
