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

A newer air conditioner may help you save 20% to 40% on cooling costs compared to units from 10 years ago, according to Energy.gov. Of course, all new units aren’t created equal. Invest in a model that’s EnergyStar certified, because these units provide 15% more energy efficiency compared to standard units, says Energy.gov.

You’re in constant need of repairs

Besides energy efficiency, the older unit may need frequent repairs to keep it in working condition. While some individual repairs aren’t that heavy on the pocket, others can be expensive. Replacing a compressor, for instance, is a costly option. However, If the system just needs an occasional repair, then don’t wait too long to call your repairman.

Unusual system noise

Like any system, your HVAC system also produces some noise at it operates. The hum, for instance, is a normal noise. But, if you start to hear unusual noises, like rattling or hissing sounds, then you should get the system checked. There can be multiple sources for the noises. For example, there can be rattling in an old system because the duct sealant between duct pipes has gone and the pipes are hitting each other. 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.
