Amazing service after 7pm! Heater wasn't blowing out air from the vents. I called and spoke with John. We are a repeat customer. They had been out a few years back to replace a part on our older heating unit (that we didn't buy from them).
On our phone call he took the time to trouble shoot some things with me and eventually walked me through how to reach the filter for the unit. (Turns out, this was the problem.)
He could have easily made us schedule a service call, but helped us right over the phone. During Dinner! No charge. Told us exactly what kind of filter to buy (and what NOT to buy). Working great now!

Antonio came to service my heat pump system this morning. I am always pleased with the service I receive from DG. Antonio was on time answered all my questions checked and tested everything efficiently. I am super happy he is part of the amazing DG team.
Thank you again for all your help today

Excellent service from DG Heating and Air! Brandon was fantastic - he provided quick, efficient service and gave us straightforward, honest advice. Instead of trying to oversell us, he focused only on what actually needed to be fixed and took the time to explain how to properly maintain our systems for years to come. Really appreciated his transparency and expertise. Definitely gained a long-time customer - we'll be using DG Heating and Air for all our regular maintenance services going forward. Highly recommend!
