Summertime means a lot of fun. However, at the same time, it’s when you need relief from the searing heat. A working HVAC system helps you get the comfort you need, so it’s important you maintain or replace it when needed. Here are 5 signs that you’re in need of a new HVAC system:

The system can’t maintain the temperature

An older system can find it difficult to keep the cooling consistent. And, this inconsistency creates cold and hot spots around the house. The loss of cooling power of an air conditioner can be from fluid loss, thermostat issues, blocked ducts, etc. Here’s a helpful blog about the main reasons for airflow loss in air conditioners. Another factor is the size of the unit. If the system is too large for the space, then it’ll switch on and off too often. If the problems with the system persist after repairs, then it may be time to think about a replacement.         

The system has been in use for a decade

Or, the rattling may be because of a stone stuck in the outdoor duct. 

Odors coming from the duct

Like noises, there can be different sources for the smell as well. It can indicate a serious problem with the wiring or mold from the condensation from the air conditioner.
