We called Quality Heating and Air when our electricity bill was very high 2 months in a row. They came out in March 2015, and looked at our system. Quickly Austin diagnosed our two problems, a bad thermostat, and the heat pump was not set up correctly. He installed a new Carrier Thermostat, and rewired our units. He stayed until everything was set up correctly, and showed me how to use the website to control the thermostat. He came back a few days later, when the weather was warmer, to check on the heat pump to make sure it was running correctly. We are very pleased with the work they did for us, and will only call them for our heating and air conditioning problems in the future. Austin went above and beyond to fix our problem, even consulting with the manufacturer of our unit. Best of all, his fix saved us $120 on our next electricity bill!
