"I was extremely pleased with the work Ductz of Mid-Michigan did for me this past week. They cleaned and sanitized my HVAC ducts as well as my dryer vent. The owner, Doug, thoroughly explained the process, provided me with a quote and scheduled the work for the following week. Jonna arrived on time and professionally completed the work as scheduled despite not having his partner not being available."

Heating and Air Conditioning questions, answered by experts

While most air conditioners can last between 10 and 20 years, they will only last this long (or longer) if properly taken care of. Routine maintenance and inspections help keep your AC unit running in tip-top shape but understanding what factors will decrease its lifespan will also help keep your unit running cool.

Some things that shorten your AC’s lifespan include:

  • Extreme outdoor conditions, like high humidity or extensive salt spray 

  • Improper installation

  • Extended run times, either by the unit being too small or the thermostat setting too low

  • Not performing required maintenance

At a minimum, an HVAC system should be serviced once per year. However, a twice-a-year service schedule—once in the spring for the cooling system and once in the fall for the heating system—is often recommended, especially for older systems, heat pumps, or in climates with extreme temperatures. Regular service, which includes inspection, cleaning, and maintenance, ensures the system runs efficiently, helps prevent costly breakdowns during peak seasons, and can extend the unit's lifespan. You can also schedule a service if you notice issues like poor performance or strange noises.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

The standard rule for return duct sizing is that the return vent should be the same size or larger than the supply vent. This will ensure balanced airflow in your home and reduce strain on your HVAC system.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.
