Zack HVAC Services

can’t say enough great things about Zack Services. They are reliable, communicate exceptionally well, and price their services very reasonably. I work with them often, and they are consistently wonderful to partner with. Zack, the owner, is fantastic—always willing to take the time to discuss project needs and explain the best approach to get the job done right. Zack Services is my absolute go-to for retail clients throughout DC, VA, and MD. Their team is extremely detail-oriented, which gives me complete confidence that the work will be done well—and done right the first time. I highly recommend Zack and his team at Zack Services!

We called Zack HVAC Services when our heat pump started to malfunction. Our previous HVAC company had recently been acquired by a larger firm, and the earliest appointment available was the following week. Zack HVAC was nearby, so we took a chance and called them at 7:30 AM on Saturday. To our surprise, the call was answered immediately, not by a call service but by a technician who asked that we text our details, including the furnace's serial number, so they could ensure they brought parts that could work based on the symptoms we described. By 8:30 AM, we had a same-day appointment for between 4-5 PM. We got a text at 3:30 PM telling us the technician was on the way. He arrived at 4 PM, quickly diagnosed the issue, and recommended the fix with additional options to prevent the issue in

As a homeowner you a need a group of honest professionals who are honest and priced fairly. Zack Hvac Service is one of those professionals in my book. Zack came on time to diagnose my Hvac issue and sincerely explained the issue I was experiencing. Zack also took the time to explain to me in layman terms a couple of soultions options. This made me feel much more comfortable asking him to do the work as his solutions entailed expectations and not just a price tag for repair.

I am beyond pleased with this company. We had a tricky problem and it took some time to find a company who was able to fix a drip in my humidifier.. My daughter recommended their service, based on her experience. I contacted them and right away they were able to squeeze us in and fix our leak. We are beyond thankful and will continue to get the yearly maintenance plan! Great work Zack!

Zack was very courteous and respectful of me and my home. I was already aware of my system issues and remedy through personal research. Zack verified the problem that a previous technician had diagnosed and fixed the problem at a significant cost reduction from that of the previous company. I will call Zach's HVAC first in the future.
