1 year agoExceptional Service and Unmatched Professionalism!! I recently had the most outstanding experience with Hennessy Hvac and I am compelled to share just how incredible their service truly is. After just giving birth, my air conditioning unit suddenly went out, leaving me in an urgent and stressful situation. In the middle of the summer heat, with a newborn at home, the situation felt dire. However, Hennessy came to our rescue in a way that surpassed all expectations. Within just 30 minutes of my call, one of their technicians arrived at my door. I was immediately impressed by his promptness and the level of professionalism he demonstrated from the moment he arrived. He quickly assessed the issue, clearly explained the necessary repairs, and provided me with an incredibly fair and honest estimate. It was clear that he was not just trying to make a sale but genuinely cared about providing the best possible service. What truly stood out to me was the level of care! Given my situation, he prioritized my service and ensured that everything was handled swiftly and efficiently. The price I was quoted was more than fair-especially given the urgency of the situation. In fact, it was the most reasonable price I've ever encountered for such high-quality work. The repair was done quickly and effectively, and my home was cool and comfortable again in no time. But beyond the technical expertise, it was the customer service that left the greatest impression on me. Hennessy HVAC is without a doubt, the best service provider I have ever encountered. The combination of promptness, professionalism, fairness, and genuine care for their customers is truly rare. If you're looking for an HVAC company that goes above and beyond, provides exceptional service, and treats you with respect and honesty, look no further than Hennessy Hvac! I cannot recommend them highly enough and will be relying on them for all future HVAC needs. I can't thank you enough!! -

1 year agoHennessy HVAC is a man of the people! He came out on short notice on a Sunday to troubleshoot and repair my AC unit. He was great with explaining everything in detail and checking for other issues in the house. A great troubleshooting plumber as well as HVAC. I highly recommend his services. His quality of work and pricing will not be beat.

FAQ
How does Hennessy HVAC determine pricing for HVAC repairs and replacements?
We provide detailed written estimates that break down all costs, including equipment, labor, permits, and materials so you understand exactly where your money goes. Our pricing reflects the specific needs of your home-factors like system size, ductwork condition, and any necessary upgrades are evaluated during an in-home assessment. We're transparent about what's included in the estimate and what isn't, so there are no surprises when the work is complete.
Are you licensed and insured to perform HVAC work?
Hennessy HVAC maintains the proper licensing and insurance required to perform HVAC repairs, replacements, and related work in Georgia. This protects you from liability in case of accidents or property damage during the job. We handle all necessary permits and inspections on your behalf, so you can have confidence that the work meets local codes and standards.
What services does Hennessy HVAC offer beyond standard air conditioning and heating?
In addition to HVAC repairs and full system replacements, we handle water heater installations and plumbing work to address multiple home comfort needs. This means you can rely on us for heating, cooling, hot water, and related plumbing issues without coordinating with multiple contractors. Our team's broad expertise allows us to spot and address issues that might affect your overall home systems.
What should I expect for scheduling and response times when I call for service?
You can count on quick response times, including availability late on weekends when many other contractors aren't available. We provide accurate time estimates so you know when to expect us and can plan accordingly. Our goal is to minimize disruption to your home while getting your system back to working order as quickly as possible.
How does Hennessy HVAC handle cleanup and debris removal after installation or repair work?
We leave your home in clean condition after every job, removing debris and materials associated with the work. Since we also offer junk removal services, we have the expertise to handle waste disposal properly and efficiently. You won't be left dealing with old equipment, packaging, or mess-we take care of that as part of our service.
Why should I hire a professional instead of attempting HVAC work myself?
HVAC systems are complex and require specialized knowledge to install or repair safely and correctly. Improper installation can reduce efficiency, shorten equipment life, and void warranties, ultimately costing you more money. Our technicians have the tools and training to perform load calculations, verify proper refrigerant charge, inspect ductwork, and ensure your system operates at peak performance-work that protects your investment and keeps your home comfortable year-round.
