His Heating And Cooling: Licensed HVAC Services Serving Irmo 29063

Common signs include warm air blowing from vents, ice forming on refrigerant lines or the outdoor unit, a noticeable hissing sound, and a sudden spike in your energy bill. If you notice these, it's a repair that should be addressed promptly by a professional like us to prevent compressor failure and restore cooling efficiency.

We generally recommend checking your filter monthly and replacing it every 1-3 months. In Irmo, with our pollen seasons and typical household dust, a more frequent schedule (every 30-60 days) is often best. A clogged filter restricts airflow, strains your system, and reduces indoor air quality. Our maintenance plans include reminders and filter checks.

Consider replacement if your system is over 10-15 years old, requires frequent repairs, causes uneven temperatures in your home, or leads to consistently high energy bills. For Irmo homeowners, upgrading to a modern, energy-efficient system can provide better humidity control, significant cost savings, and greater reliability, which we can assess during a consultation.
