We Install The Highest Quality Equipment

Five Star Charleston Heating & Air is proud to be partnered with Lennox, one of the most trusted HVAC dealers in the industry. Lennox offers high quality air conditioning equipment at a variety of price points to accommodate to every home and budget.

You’ll enjoy these benefits when you upgrade to a properly sized, efficient Lennox system:

  • Improved home comfort. Newer air conditioner models provide most consistent cool air throughout your entire home, and operate more quietly.
  • Increased energy efficiency. The Seasonal Energy Efficiency Ration (SEER) rating measures the cooling your air conditioner generates compared to the amount of energy it uses. When you upgrade to a new system, you are likely to noticed greater efficiency.
  • Lower energy costs. Since you will see greater energy efficiency from your new system, you will naturally utilize less energy and as a result, pay less on your monthly bills!
