If yours struggles to keep up, makes strange noises, or causes dry air and high energy bills, it might be time to call in the pros. At R.S. Andrews, we specialize in full-service furnace care, including repairs, replacements, and routine maintenance. Our technicians work with both gas and electric models, making sure each system is safe, clean, and running at its best. Homeowners across the Atlanta Metro Area count on us for dependable service and lasting comfort, year after year.

Noticing Furnace Problems? Let’s Catch Them Early

Furnace issues often start small, but they rarely fix themselves. If you’ve spotted any of these warning signs, it’s a good idea to have a professional take a look before things get worse—or more expensive.

  • Cold Air Instead of Heat: This may point to a faulty igniter, pilot light issue, or thermostat miscommunication.

  • Unusual Smells: A burning odor could mean dust buildup or something more serious like an electrical problem.

  • Frequent Cycling: Constant starting and stopping strains your system and wastes energy.

  • Noisy Operation: Rattling, banging, or whistling sounds often signal loose parts or airflow problems.

  • Weak or Uneven Airflow: Your furnace might be struggling with a clogged filter, failing blower motor, or blocked ducts.

  • Higher Utility Bills: If your usage hasn’t changed but your bills have, your furnace could be losing efficiency.

Schedule today! We’re ready to deliver expert service and a smile to your door.

My water heater broke unexpectedly and I called RS Andrews for a quote. Due to some faulty valves in the house I had to turn the water off at the street. Their plumber, Eric Sanchez, came as soon as possible and stayed until the job was done even though it was well after working hours on a holiday weekend. The price was very reasonable. Will definitely recommend this company in the future. Eric, thank you for working late to get the water back on for my family!

I had my annual AC maintenance completed by Calvin Russell from RS Andrews, and I couldn’t be more pleased with the service! Calvin was professional, knowledgeable, and took the time to clearly explain everything he was doing. He identified that my capacitors needed replacing and handled it quickly and efficiently, making sure my system will run smoothly through the season. What really stood out was his friendly attitude and attention to detail—he made sure all my questions were answered and gave me peace of mind about the condition of my AC unit. It’s not every day you find a technician who combines skill with such great customer service. If you’re looking for a reliable, courteous, and thorough technician, I highly recommend asking for Calvin Russell at RS Andrews.

Awesome service. James May was service man and he did an excellent job. He explained what was wrong (I had low water pressure but didn't understand how that happens) and what the cost would be. He worked until it was fixed properly.

"Our technician(Charlie McQueen III),was a lifesaver! We had a confusing A107 error code on our new Rheem hybrid water heater after it was installed because the leak sensor got wet. Charlie diagnosed the issue immediately, and was incredibly patient and knowledgeable. He thoroughly explained how the system works and what we needed to do to get the sensor completely dry. Thanks to his help, we were able to clear the error code and get our unit running perfectly. Highly recommend!

Smelled a slight gas leak and repairman Ivan Medina performed leak search on gas line connected and discovered leak at the flare on flex line. He replaced flex gas line and rechecked for gas leak. No gas was detected after replacing line. Repaired under warranty so no charge. Many Thanks, James ( a very satisfied customer).

Had a tremendous experience with RS Andrews and Keyshawn J. We had another company out to check a problem after a leak and they reported back "nothing wrong except your system is old and needs a replacement". Then 24 hours later the system stopped working. Called RS Andrews...they sent Keyshawn the same day...then he proceeded to not only diagnose & fix the problem, but assured us our unit still has a little life left. AND RS Andrews didn't even charge us for the visit because they have a "free second opinion" policy. Will definitely be contacting RS Andrews when it's time for a new system. Appreciate the great service and Keyshawn was helpful, polite, explained everything in detail & earned our trust.

RS Andrews sent their HVAC Technician Jonathan Balom who did an amazing job of serving our A/C unit that was blowing hot air on short notice. He replaced the worn out capacitor with a new one, so we didn't have to replace our old A/C unit. RS Andrews is a trustworthy company that I would recommend for Heating, Cooling, Plumbing and Electrical issues. Thank God I heard about these guys from the radio ads because what they say delivering smiles is true. They definitely delivered a smile for us.

RS Andrews has surpassed all my expectations for quality work, experienced team members, and prompt attention to my requests. Amber Magnus, my sales rep, was personable, efficient, and professional. She took the time to answer all my questions and to help me understand what work needed to be done to install a new HVAC and why. The installation crew was just as knowledgeable, personable, and worked together efficiently, with great attention to protecting my home. I commend this company for their focus on customer service. It is becoming more and more rare in today's environment.

Excellent! Jose was our technician and he was GREAT. Very personable, knowledgeable, and hardworking. It was clear he knew exactly what he was doing. His assistant, Justin, was also great. They replaced the booster fan and other piping in our laundry room. They left the laundry room very clean and then took time to answer our questions and review their work. Highly recommend.

Since the first day I contacted RS Andrews, the service has been top notch! From the attentiveness of the customer service person responding to the calls, to Thomas who came out for the repairs. Thomas was such a breath of fresh air! He was kind, knowledgeable, informative and did an absolutely amazing job identifying where the plumbing issue came from, to the actual repair. I was bracing for an astronomical price, but GOD!! Thank you RS Andrews for who you are and how you care for your customer base🙏🏽.

Paul Creel is a great representative of your company. Paul did a repair of the main water line coming into my residence. He explained the work process and provided me with an estimate. The work was completed in a timely and professional manner. I am very satisfied with the work and clean up of the area. I will recommend your company to friends and family. WT 8/14/2025
