They didn’t change my filter which is what I thought was part of the maintenance cost. Now I gotta go buy one and do it myself. Attention to detail lacking.

Exceptional Service ! Southwest Heating & cooling recently installed a new central A/C unit at mother’s home. She is 92 y/o with compromised health. Mike & Lisa went above and beyond in securing the AC unit & getting it installed promptly. They were thorough and timely. They were extremely kind and gentle with Mom. All communications were clear, concise and timely. 5 stars. Best of the Best ⭐️⭐️⭐️⭐️⭐️

Jonas and Joey did a great job installing a heat pump with backup furnace. The installation took two full days, in part because we didn't already have an air conditioner. Throughout the process, they worked hard without breaks while being extremely courteous. They took the time to answer all my "stupid user" questions, and also answered many questions I didn't think to ask. My basement and garage are cleaner now than before they came.

Joe was able to diagnose our problem and fix our AC. We previously had another company tell us our unit was not the correct size. And should be replaced.

Amazingly fast response to a big weekend problem I discovered. Can't thank Joseph Winberg and the scheduling team enough. Everywhere else I called failed to schedule or was 3 weeks+ out... Southwest had great rates, took their time, and fixed it all within 24 hours.

Joseph was extremely knowledgeable and have me many insights to my HVAC system. Unfortunately we were not able to install a humidifier due to lack of space in the utility room. I would surely call him again for any other HAVE service needed.
