What We Do

Complete HVAC Service

From a single capacitor replacement to a full system installation, Bob and his team bring factory-level training and small-shop honesty to every job.

Air Conditioning

AC installation, repair, and maintenance on all brands. Same-day service during Atlanta summers. Mini-split options for sun rooms and basements.

Heating & Furnace

Furnace installation, repair, and annual tune-ups. Gas and electric systems. We diagnose before we prescribe, so you don't pay for parts you don't need.

Mini-Splits & Ductless

Ductless systems for sun rooms, basements, additions, and rooms that never get enough comfort. Zone your home instead of blasting the whole house.

Duct Design & Repair

One customer was told they needed a new system. We found a large duct gap instead and saved them thousands. Proper duct work is half the system.

Tune-Ups & Maintenance

Seasonal tune-ups and maintenance plans. Catch small issues before they become emergencies. Keep your system efficient and your energy bills down.

Second Opinions

Got a quote to replace your entire system? Call Bob before you sign anything. Multiple customers have avoided unnecessary replacements because Bob found the real issue.

Real Estate Inspections

Buying or selling? We perform HVAC inspections for real estate transactions so you know exactly what you're getting or what needs disclosure.

Air Quality

Humidifiers, dehumidifiers, air purifiers, and crawl space sealing. Atlanta weather is hard on indoor air. We make it better.

Our Story

35 Years of Factory-Level Expertise

Bob Trained the Trainers

Before Bob Roy started his own company, he worked on the manufacturer side. Corporate sales. Technical training. He's the guy who taught other HVAC technicians how to work on the systems you have in your home. More than 10,000 hours of formal training, multiple NATE certifications, and three decades of field experience.

He took all that and opened Bob's Heating and Air in 1990 with a simple promise: the big companies push replacements because that's where the margin is. He'd do it differently. Diagnose accurately. Fix what can be fixed. Replace only when replacement actually makes sense. And answer the phone himself when you call.

Thirty-five years later, that promise is still how he runs the business. It's why he has won Nextdoor Neighborhood Favorite four years running. It's why customers call him after other companies have quoted them thousands in unnecessary work. And it's why North Atlanta homeowners trust Bob, Josh, and Shawn with their comfort.

Common Questions

HVAC FAQ

Absolutely call us first. This is one of our most common service calls. Multiple customers have come to us after being told they needed a full system replacement, and we found the real issue was something much smaller: a failed capacitor, a leaking duct, a dirty condenser coil. Bob's factory training helps him see past the easy "replace everything" answer.
All brands. Trane, Carrier, Lennox, Goodman, Rheem, Amana, Bryant, York, American Standard, Mitsubishi, Fujitsu, Daikin, and more. Bob's background as a manufacturer trainer means he knows the differences between brands inside and out.
Yes. Mini-splits and ductless systems are one of our specialties. They're perfect for sun rooms, basements, garage conversions, additions, and any space that your central system struggles to reach. We design the right configuration for your home and install it cleanly.
Same-day service is our norm during Atlanta summers and winters. Our regular hours are 8 AM to 9 PM Monday through Saturday and 9 AM to 4 PM Sunday, which covers most emergencies. Multiple customers mention us showing up within 30 minutes of calling.
Yes. We perform HVAC inspections for real estate transactions so buyers know exactly what they're inheriting and sellers know what to disclose. Our inspection report is detailed and honest, not a template.
NATE stands for North American Technician Excellence. It's the industry's gold-standard certification program, requiring rigorous testing of real-world HVAC knowledge. Bob holds multiple NATE certifications plus over 10,000 hours of training. When you hire a NATE-certified technician, you're hiring someone who has proven their competence, not just their willingness to show up.
