Installation & Replacement

It’s time for that new heating system! Lang 72 Degrees is a family-owned heating installation and replacement company, located in Hilton Head since 1976.

We know how difficult it can be to determine the proper heating system for your home. What are the goals?: Energy-efficiency? Zoned air systems for multiple levels and comfort preferences? Heat pump alternatives? A modern design with the latest heating technology? The most cost-effective central heating?

These are all valid questions that should be asked when researching heating installation and replacement services. The system you install should have the greatest comfort support with the lowest possible utility bill. The trained and knowledgeable staff at Lang 72 Degrees can help with all of the above and more. We’ll let you know your available options and consult your property before making a professional evaluation.


Heating repair is one of the main reasons homeowners need to call an HVAC contractor. Any repair on any make and model; we work on all heating systems and furnace types. If you pick up on any of these repair signals, call Lang 72 Degrees for an inspection.

Common Signals for Heating Repair:

  • Lack of TLC – It’s been a year (or years!) since a trained HVAC technician checked your HVAC system.
  • Age – You will begin to experience a reduction in heating performance if your HVAC system is 10 years or older. Proper maintenance only prolongs a system’s lifespan, however repair and replacement services are inevitable with older units.
  • Water – Water leakage around your furnace is indicative of a clogged condensate line and requires professional attention.
  • Gas – A gas leak is dangerous! If you smell gas in the home, turn off the furnace immediately and call your local Hilton Head HVAC company.
  • Strange noises – If you hear noises coming from your system that weren’t there before, then your furnace is trying to talk to you. Find out why with heating repair services.
  • Inadequate airflow – Your heater may be struggling to blow any heat at all. If you are experiencing weak airflow, there is potentially a major issue with the motor. We can diagnose any issue with any make and model of heating system or furnace type.
  • Thermostat – If your heating system is frequently cycling or producing hot/cold spots in the home, we look at how well your thermostat is communicating with your HVAC unit. It could be broken and need upgrade or replacement services.

With Same-Day Service, we come to your home with a fully stocked vehicle ready to tackle most any heating issue on the spot. All of our repairs come with a Two-Year Warranty and a Moneyback Guarantee.


It is recommended that maintenance be done on your home’s HVAC equipment twice a year — heating maintenance comes up in the fall before winter hits. Not every piece of the maintenance checklist has to be completed by a professional technician. Changing your filter is a DIY job with big impact. Switch out your filter every 30-60 days, or as needed based on system use. Changing your filter clears debris from the system and improves indoor air quality.
