HVAC reviews in Missouri Valley, Iowa

We had an issue come up after hours and weren’t sure what to do, but Guinan Heating and Air answered our call right away. They were incredibly kind, patient, and knowledgeable, and took the time to walk us through exactly what we needed to do to keep our family safe until service could be done.

It meant so much to us to have someone respond so quickly and genuinely care about helping in that moment. You don’t always expect that level of service after hours, but they went above and beyond.

We are so grateful and would absolutely recommend Guinan Heating and Air to anyone looking for a company that truly cares about their customers!
