Customer Reviews

Jeff Sample

Graham was incredibly personable and always was honest in his assessments of the work done. Had his guys come out a second time when insufficient insulation had been blown in and had them get it up to code. Highly recommend

Katie Smith

Jeffrey’s service was 100% what you want from a home service company!!!! He sets the bar high for others. I was completely impressed with how he took care of our home and am so grateful to know I have a trusted company to call on in the future. A Kudos to the incredibly kind and knowledgeable CSR who took my call, I wish I remembered her name, but that’s on me, not her. She was professional and empathetic when handling my call. I felt reassured from the very first moment that Anchor was going to take care of me and my home.

Rainer Shea

Rick was very professional and knowledgeable. He was at my house within an hour of calling to request help. His diagnostic and explanation was extremely clear and helpful. The quote was very reasonable and he provided good tips for how to keep our system running well. I will be switching to Anchor for ongoing maintenance/support.

Brendan D'Andrea

Jack was terrific. He arrived on time and was courteous and personable. He was not in a hurry and took the time to explain things. He showed me pictures of his meter readings of my equipment and reassured me that all were very good. He explained what the settings should be when my system is on “auto” and why they were important. I would highly recommend Jack and Anchor Heating and Air and give him 5 stars.

Joel Mensonides

I had an excellent experience with Anchor Heating & Air from start to finish. The level of professionalism demonstrated by both their technicians and leadership team truly sets them apart in an industry where reliability and accountability matter. The technicians were punctual, knowledgeable, and respectful of my home. They took the time to clearly explain what they were seeing, walked through options without pressure, and completed the work efficiently and to a high standard. It was evident they take pride in their craft and are well-trained, not just technically, but in customer service. Equally impressive was the leadership behind the operation. Communication was clear, expectations were managed honestly, and follow-through was exactly as promised. That kind of operational discipline and integrity reflects a company that is well-run and committed to long-term relationships, not quick transactions. If you are looking for a heating and air company you can trust—one that combines technical expertise, professionalism, and strong leadership—I would confidently recommend Anchor Heating & Air.
