We own two properties, one we live in. We had new HVAC systems installed in both homes. Jesse was very thorough in his assessment of what we needed and gave us bids for each home with different levels of pricing options. We also got bids from two other companies and Gary Frank was within their range. Jesse spent a lot of time answering our questions, reviewing options, and explaining technology even before we committed to using their company. I felt very knowledgeable after my discussions with him, in addition to doing my own research. Jesse also was on site for the installation, overseeing all the work, which we appreciated. Most companies have a separate person who does the bid but does not participate on site for the work. The crew worked diligently and were very professional throughout their time at our home. Our new system is great too! I highly recommend Gary P. Frank. Our entire experience from start to finish was excellent and they were worth every penny.

What set Gary Frank HVAC apart right away was their customer service. Because it made sense to replace my entire HVAC system, their representative, Nick, sat down with me, walked through the proposal in detail, and patiently answered all of my questions. That level of clarity and follow-through continued throughout the project. After the full HVAC system replacement, the improvement has been significant, with more even heating and cooling between floors, excellent humidity control, and easy control of the system via an app. They were also the only company I spoke with that knew how to process the complex Pepco rebates and tax credits available for high efficiency systems at the time, which saved me thousands. The entire system was installed in one day, cleanup was excellent, and the system has performed beautifully through both summer and winter. Highly recommended.

No one ever calls an HVAC contractor because they like opening their checkbook. I’ve had occasion to use a number of local HVAC contractors over the years but I’ve used Gary P Frank to install a new zone of air conditioning, and recently repair another zone that had been installed by another company years ago.
I’ve worked both times with their tech “Nick”. Nick has been the epitome of professional, explaining everything like I’m 5, taking his time to give me all the options, including ones that are the least cost.
Once onsite, they are polite, efficient and leave the site as clean as they found it.
Full disclosure, they aren’t the cheapest (nor the most expensive), but are responsive and professional. Highly recommend.
