We had an older furnace which we attempted to have serviced annually but unfortunately the services were not performed properly and we finally had to replace it. We emailed CoreTemp and had a call within 30 minutes asking if our furnace was working and to set up time for a quote. The passion, knowledge, thoroughness of describing our options and the professional follow-up with available installation dates and willingness to install in a low space led us to choose Richard and his team. The installation was professionally done, around our schedule and needs, and executed with friendly and knowledgeable staff. The unit is perfect for our home and is working like a charm, we are thrilled with the product and installation. We have also engaged them to install our new A/C unit this spring for which the pre-work is already done. We would, without hesitation, recommend Richard and his team.
