Like any other equipment, HVAC systems can breakdown. When your home HVAC system needs a repair, it can be an inconvenience. But when your business HVAC system breaks down, it affects your productivity as well as your cash flow. At the least, it's a huge interruption to your work, and some repairs can shut down your business until they're fixed. That's why you need a commercial maintenance agreement.

A noisy commercial air conditioner is not something that should be ignored. Prompt attention may allow you to correct small issues before they become larger and more expensive ones. It is possible that the fan has become bent or has an obstruction which is causing the noise; loose screws and a motor in need of lubrication may also be the cause. Unfortunately, some loud banging or clanking noises indicate a worn out motor or shot bearings. If this is the case, it may be time to consider upgrading your older unit with a high efficiency modern air conditioner which will save you money on utility expenses.

Efficient modern air-conditioning home zoning procedures avoid the pitfalls of faulty methods associated with managed AC performance. Although rumors of old suggest closing AC registers in unused rooms, the power of modern home zoning follows a more efficient process. In fact, according to the HVAC discussion board at U.S. Home Energy Saving Pros, zoning via restricted air flow can result in an overheated heat exchanger. Effective home zoning requires balanced HVAC airflow.
