What Our Customers Are Saying

Wow!! We are so happy we called Hammond Air!! They called me right back! Our unit was freezing up not a great time to be without air conditioning since I have asthma too. Jim came out on time and was super nice and so professional!! He checked everything and was so honest. We highly recommend Hammond Heating & Air Conditioning..


I had my AC drain flushed and the air balanced, as some rooms in my home were much cooler than others. Clayton was very professional, explained what was going on and how to keep up with my air maintenance to keep my electric bill down.


These guys are awesome! Very quick, very friendly. Dave & Ron are great guys, very nice and patient with all of our questions!!! Realistic and affordable pricing. Very informational estimate experience from Clayton too. No pushing on the sales prior to our decision, either. (Which we allll know is ideal) Great experience all around.
