FAQ’s

Maintaining unrestricted airflow is the most crucial aspect of HVAC maintenance. Dust, dirt, and debris can significantly hinder your system’s efficiency and lead to costly repairs. It’s essential to keep filters clean and ensure that both indoor and outdoor units, including heat exchangers and coils, remain free of obstructions.

To keep your system running smoothly, we recommend having your heating and cooling equipment inspected and serviced twice a year—ideally in the spring and autumn. Additionally, changing your filter regularly, based on the type you use, can prevent many common issues and significantly lower the risk of major system failures.

Replacing your filters regularly is essential to keep your heating and cooling system running efficiently and to maintain good indoor air quality. Clean filters help ensure proper airflow and reduce the presence of dust, allergens, and germs in your home. Depending on the type of filter, replacements may be needed on a weekly or monthly basis. At National Refrigeration LLC, our technicians will provide expert recommendations on the best filters and replacement schedules to suit your system’s needs, ensuring peak performance year-round.

To determine if your system is functioning as it should, ask yourself the following questions: Is it making strange noises? Is it cooling or heating your home evenly? Has it started taking longer to reach the desired temperature? Have you noticed an unexpected increase in your utility bills? These are all signs that your HVAC system may need servicing. Addressing issues promptly can prevent them from escalating into more costly problems. If you notice anything unusual, be sure to contact National Refrigeration LLC for a thorough system check.

Excessive humidity in the summer or dryness in the winter can often be traced back to poor equipment performance, improper installation, incorrectly sized units, or leaky ductwork. If you’re experiencing uncomfortable humidity levels, National Refrigeration LLC can conduct a Complete Home Evaluation to identify and address the root cause, helping you maintain a comfortable indoor environment year-round.

Generally, National Refrigeration LLC recommends replacing disposable filters at least once a month. If you have washable filters, they should be cleaned monthly. Our service technician can recommend the ideal replacement schedule to ensure optimal efficiency and filtration for your specific system.

While most maintenance tasks should be handled by a qualified technician, there are a few things you can do to help keep your system running smoothly:

• Keep outdoor units clear of debris, clutter, and weeds to ensure proper airflow.
• Be cautious when using weed trimmers near the unit to avoid damaging control wiring.
• Keep pets away from the unit, as pet urine can lead to costly damage.

Taking these simple steps can help maintain optimal performance for your HVAC system.

 It’s recommended to have your air conditioning system professionally serviced at least once a year, ideally in the spring or early summer. Regular maintenance ensures your system runs at peak efficiency and allows technicians to identify potential issues before they become major problems, helping to prevent unexpected breakdowns during the hottest months.
