Some Words From
Our Customers

Carrington came out today to service our furnace in Roswell. He was a very nice young man and he took pictures as he worked to show me and explained everything well. It was a pleasure to have him out to our home! I will tell all of my Horseshoe Bend neighbors about my great experience.

- Samuel P. 

“When we woke up to no hot water, I was in a panic getting ready for my day. Guardian was our first call. The plumber that came out was so very thorough in explanation, gave me a few options and the information needed to make our decision. We ended up with a tankless water heater and I love having hot water on demand!”

- Casey G.

"I never understood yearly maintenance on my home systems. When Guardian came out to my home to fix a problem, they explained the benefits to me and we chose to use them for our seasonal tune ups. They were right…I feel like we have less dust in the home and the air flow is better!"

- Adeline H.

Roswell, Ga's Frequently Asked Questions

How fast can you get to Horseshoe Bend or Martin's Landing? Because our trucks are frequently staged near the Holcomb Bridge Road and GA-400 corridors, we often offer same-day service for cooling and plumbing emergencies in East Roswell.

Do you have experience with historic homes near Canton Street? Yes! Historic Roswell homes require specialized knowledge of older ductwork and plumbing. We specialize in retrofitting high-efficiency systems (like Ductless Mini-Splits) without compromising your home's historic aesthetic.

Can I get a rebate for a new HVAC system in Roswell? Absolutely. We help Roswell residents secure Georgia Power rebates and navigate the 2025 Federal Tax Credits (up to $2,000) for high-efficiency heat pumps and furnaces.

What if I have a plumbing emergency near the River? High moisture levels near the Chattahoochee can lead to unique pipe and humidity issues. We offer 24/7 emergency response for burst pipes, sewer backups, and water heater failures.

How does the Chattahoochee River affect my home's HVAC system? Living near the river increases local humidity significantly, which can lead to mold in crawlspaces and "sticky" indoor air. We specialize in Whole-Home Dehumidification systems that work alongside your AC to pull moisture out of the air, protecting your hardwood floors and improving respiratory health for Roswell families.

Does Guardian handle commercial HVAC for businesses on Canton Street? Yes! We provide light commercial HVAC repair and maintenance for Roswell's local businesses, restaurants, and retail shops. We understand that a broken AC means lost revenue, so we prioritize rapid response for our local business partners in the Historic District.

Why is my water bill so high in Roswell? If you've noticed a spike in your water bill, you may have a hidden leak or a malfunctioning outdoor irrigation valve. Roswell's rolling terrain can sometimes cause pressure fluctuations. Our licensed plumbers will work diligently to find the source of the problem without tearing up your yard or floors.

My Roswell home has "hard water" spots on the fixtures. Can you help? Yes. Many neighborhoods in North Cobb and North Fulton experience mineral buildup. We install Whole-Home Water Softeners and carbon filtration systems that eliminate scale buildup, extending the life of your appliances (like your dishwasher and tankless water heater) and making your skin and hair feel better.

What makes your "Meet or Beat" guarantee different for Roswell homeowners? In a market where corporate HVAC companies often overcharge, our Meet or Beat Guarantee ensures you get the best value. If you receive a written estimate from any licensed Roswell contractor for a full system replacement, we will meet or beat that price while providing our superior "Knight Code" installation and a better warranty.
