Proper heating maintenance will ensure your heating systems’ longevity and keep the air quality clean. In addition to clearing out contaminants, periodic maintenance will help you determine your heater’s age and overall performance before you need to replace it.

On average, an AC conditioner will last between 10-15 years. However, if properly maintained and with regular check-ups, some can even last up to 30 years.

Your air filters should be cleaned and inspected every 3 months to ensure proper performance.
