No matter the problem you may experience with your heating and cooling system, you can rest assured that we take great pride in our work and it is all guaranteed, 100%. We can work on any equipment, whether it’s air conditioning, heating, or refrigeration; residential or commercial. We can even help you improve your Indoor Air Quality. We have a full-service staff that includes: NATE certified technicians, Precision Tune-up Specialists, Comfort Advisors, installation crews, and an office staff.

Customer Satisfaction & Community Involvement

There is no other company that cares as much about customer satisfaction as Lang’s 72 Degrees. Just ask any of our customers about our Incentive Programs and Customer Appreciation Days. With our involvement in community programs, such as Christmas for our Soldiers, and our commitment to customer care, you will see that we do much more than just heating and air.

If you reside in Beaufort, Jasper, or Chatham County, we can be there, with our exclusive same day service. We have 20 fully stocked trucks ready to go. Best of all, we are opened 24 hours a day, 7 days a week. Unlike other HVAC companies who only advertise the concept, we offer true 24-hour service.

On Mother’s Day our air conditioning system went out. After calling around to three other heating and air companies we found out that none of them offer true 24-hour service as they advertise. Our fourth call was made to Lang 72 Degrees and a live person actually answered the phone! Your service technician came out and had our air conditioning system back up and running within 45 minutes of our phone call! Great job, thank you Lang 72 Degrees. – Philip & Karen Messina
