Durham Heating & Cooling

It’s recommended to schedule HVAC maintenance twice a year, ideally in the spring for cooling systems and fall for heating systems. Regular tune-ups ensure your system runs efficiently, reduces the risk of breakdowns, and extends its lifespan. Routine maintenance can also improve air quality and lower energy bills.

If you notice weak airflow, unusual noises, frequent cycling, or higher energy bills, your HVAC system may need repairs. Other signs include uneven temperatures or a system that struggles to maintain comfort levels. Addressing minor issues early can prevent costly breakdowns.

A system blowing warm air could be caused by a dirty air filter, refrigerant leaks, or a malfunctioning thermostat. A clogged filter restricts airflow, while low refrigerant levels prevent the system from cooling properly. Scheduling a professional inspection can help diagnose and resolve the issue.

To improve energy efficiency, replace air filters regularly, seal duct leaks, and install a programmable thermostat. Keeping your system well-maintained and ensuring proper insulation also helps reduce energy consumption. Upgrading to an ENERGY STAR®-rated system can further enhance efficiency.

Strange noises like banging, rattling, or screeching can indicate loose parts, motor issues, or a failing blower fan. Ignoring these sounds may lead to more serious damage over time. A professional technician can identify the source and prevent further complications.

Most HVAC systems last 10 to 15 years, depending on maintenance, usage, and the quality of the unit. Regular maintenance and timely repairs can extend the lifespan and keep it running efficiently. If your system is over a decade old and frequently breaking down, it may be time for a replacement.

First, check the thermostat settings, replace the air filter, and inspect the circuit breaker to ensure the system is receiving power. If the problem persists, it’s best to call a professional technician to diagnose the issue. Attempting DIY repairs on HVAC systems can lead to further damage or safety hazards.

Improving indoor air quality starts with regular filter changes, duct cleaning, and using an air purifier. High-efficiency filters and UV light systems can help remove allergens, dust, and bacteria. Keeping humidity levels balanced with a humidifier or dehumidifier also enhances air quality.
