Why Proper AC Installation Matters in Charleston
Proper installation is critical to the performance and lifespan of your air conditioning system—especially in a climate like Charleston, SC, where systems run frequently due to heat and humidity.
The U.S. Department of Energy notes that improper installation is a leading factor in poor performance, increased repairs and early system failure.
Undersized units run for long periods. Oversized units reach the set temperature quickly and switch off without removing humidity, leaving rooms feeling clammy. Both oversized and undersized units break down more often and can reduce efficiency by up to 30%.
M&B Heating and Air uses industry standards for each new AC installation. Several factors affect the size of the system to install including:
- Square footage.
- Building orientation and local climate.
- How rooms are used.
- Number of doors and windows.
- Amount of insulation.
- Landscaping and shade.
Whether you are building a new home and need a new AC installation or require an upgrade or replacement, we tailor each installation to your needs. We properly size the HVAC unit for optimal comfort.
