I was having trouble with my heat pump mini split units that had been installed by another company. I called Lawrence Air and they were able to send someone out the same day to diagnose the issues and also perform routine maintenance on the whole system. I worked with Brandon and he was very knowledgeable and explained everything to me along the way as he diagnosed and then resolved the issues. He was able to get everything up and running again that same day and I am so grateful to have a fully working system again. I will definitely be using Lawrence Air in the future for my HVAC needs!
