What Homeowners in South Brunswick Ask Us

Why do I have weak heat coming from my vents?
A heating system that is on but not warming the home properly may be dealing with airflow restrictions, thermostat calibration problems, dirty burners, or worn ignition parts. Across Middlesex County, weak heat often traces back to airflow restrictions, thermostat settings, or overdue maintenance. It is worth checking before cold weather puts more strain on the unit.

What causes an AC system to run without cooling properly?
If your AC is running but the house is still warm, the usual causes are a dirty filter, thermostat settings, low refrigerant, a frozen evaporator coil, a blocked outdoor unit, or a failing capacitor or compressor. In many Middlesex County homes, dirty filters, older ducts, and heavy summer runtime make cooling issues show up fast. A professional diagnosis is the fastest way to prevent more expensive damage.
