“Our AC started making a terrible grinding noise late Friday afternoon before a holiday weekend. I was certain we’d be sweltering for days, but Blanton & Sons had a technician at our Charleston home within two hours. He identified a failing fan motor, had the part on his truck, and had us cooling again before dinner. Their emergency service saved our weekend!”

When to call for HVAC services in Charleston
Strange Noises
Grinding, squealing, or banging sounds from your HVAC system indicate worn components that could cause expensive damage if ignored. Early repairs cost much less than emergency replacements.
Uneven Temperatures
Hot and cold spots throughout your home suggest ductwork problems, failing equipment, or airflow issues that waste energy and reduce comfort in your living spaces.
Rising Energy Bills
Sudden increases in electricity costs without changing usage patterns often mean your HVAC system is working harder due to failing components or efficiency problems.
Poor Air Quality
Excessive dust, musty odors, or family members experiencing more allergies can indicate ductwork contamination or inadequate filtration that affects your health and comfort.
Frequent Cycling
Systems that turn on and off constantly struggle to maintain temperature, indicating thermostat issues, refrigerant problems, or equipment sizing problems that need professional attention immediately.
