This was my first time using Sanford. Derek was amazing. He diagnosed the problem quickly, showed me the problem, and then quoted me a price which was very reasonable. He had the part on the truck and had the problem fixed within a half hour. From the person I made the appointment with, Irish, to the dispatcher I spoke with for an estimated time of arrival, to Derek, my experience was nothing but positive. I had such a great experience that I will always use Sanford for my heating, cooling, and plumbing needs. Highly recommended!

After Sanford did such an impressive job installing our new Bosch furnace last winter, it was a no brainer as to who we wanted to add a central air conditioner to our house.
They gave us two options and we chose to go with a heat pump. Jason and his team did an incredible job installing the system in just a single day. The quality of their workmanship is second to none and he couldn’t be a nicer person to work with.
Another great job by Sanford !

We had Brian B come to our home to conduct a follow up visit to evaluate our Carrier AC that was installed in February. Just like the three-man crew who did the installation, Brian B did an outstanding job of making sure that everything was working just fine. He answered all our questions and made sure we were confident that our AC would be working fine this summer. Great job.
