Heating and Air Conditioning questions, answered by experts

They can, but it’s not as common. Window AC units are much smaller than whole-house systems and less likely to develop refrigerant leaks or similar issues. As a result, you will rarely need to add a new refrigerant, limiting overcharging problems. However, it’s still important to leave refrigerant management in the hands of professionals when window units need work.

While many states do not have specific licensing requirements for HVAC companies, your local city or county might. It's always a good idea to check local requirements online and use a tool like Angi’s contractor license lookup to confirm that the company you’re considering is licensed. Regardless of licensing, you should always ensure the company you hire is fully insured to avoid potential lawsuits if a technician is injured on your property. Additionally, it is recommended to check if the company holds third-party certifications, such as North American Technician Excellence (NATE) certification or R-410A certification, which qualifies them to work with HVAC refrigerants.

A damper motor can last up to 15 years, but it can wear out more quickly than that if you run your HVAC unit a lot. So you might expect a longer life in a colder climate than if you live in a warmer climate.

Evaporator coils in HVAC systems typically last around 10 to 15 years. However, their life span can be longer or shorter based on factors like the frequency of your HVAC system usage, whether regular maintenance is performed, and environmental conditions. Regular maintenance, such as HVAC system cleaning and coil inspection, can extend the durability and efficiency of your evaporator coil.

Yes, mini-split systems are generally less expensive to run than central air conditioners and are significantly more energy-efficient. Because mini-splits do not rely on ductwork, they avoid the energy loss associated with ducted systems, allowing cooled or heated air to reach its destination more efficiently. Additionally, they offer zoned control, meaning you can run units in individual rooms and turn them off in unoccupied areas. This capability can lead to energy savings of about 30% compared to a central air system, resulting in a lower monthly energy bill.
