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.
