I contacted them by email and they replied back within 24 hours. 2 days later, Marnie visited us. She was on time for the appointment, checked out old furnace, central AC and the townhouse layout. She was friendly and answered all our questions regarding equipment options and costs associated with the installations. As my husband was planning to repair the interlock in the backyard, Marnie was able to schedule the removal of the old AC unit the next day. Our old furnace was replaced with a high efficiency one by Kamil and Steven, both whom were friendly and precise and quick in their work. They managed to install the 2 vent pipes required by the new furnace on a short and clean route, changing the air supply grill position. The ductless system was installed by Roop and Josh one week later, who were also very quick and efficient, and worked with our wishes in the placement of the units. Overall, the work and service was wonderful and quick, and we were very happy to work with the team at Convertible Heating and Air Conditioning.
