Keeping your commercial space warm and comfortable isn’t just a seasonal concern—it’s vital to employee productivity, customer experience, and regulatory compliance. In Bluffton’s unpredictable winters, even brief heating disruptions can lead to downtime, safety risks, and lost revenue. At R.S. Andrews, we understand the urgency and complexity of commercial heating systems. Whether you need a fast repair, system replacement, or a new rooftop unit installation, our team delivers reliable, efficient solutions designed to keep your business running without interruption.

Signs Your Commercial Heating System Needs Attention

Heating issues in commercial buildings often go unnoticed—until they result in complaints, lost productivity, or unexpected downtime. Recognizing the early warning signs can help you take action before a minor problem becomes a major expense:

  • Uneven temperatures across your facility – If some areas are too cold while others are too warm, your system may have airflow or zoning imbalances.
  • Unusual noises from rooftop or mechanical units – Sounds like banging, clanking, or whistling can point to worn-out components or restricted airflow.
  • Higher energy bills without increased usage – A sudden spike in utility costs may signal inefficiencies caused by aging equipment or faulty thermostats.
  • Declining indoor air quality – Excess dust, humidity, or persistent odors could be linked to a poorly performing heating system or dirty components.
  • Recurring service calls or persistent issues – If you’re constantly scheduling repairs, it may be time to consider a system replacement.
Schedule today! We’re ready to deliver expert service and a smile to your door.

I called after hours because of a drip from our upstairs unit. A person called early the next day and scheduled a technician. Max did a great job in repairing our A/C unit upstairs in the attic, cleaning the pan and drip pipe. He was polite and knowledgeable. Your service and tech people are the best!! We do have a service contract and so worth it!

Nate was awesome! It was an after hours call. He is very knowledgeable and gave me a few things to try before arriving to see if I could fix it on my own. I wasn’t able to so he came over. He was thorough, although he figured out the issue immediately he still went through and checked everything to make sure it was running correctly. In addition to being knowledgeable he was friendly and kind. Even threw the ball for my dog.
