Choosing New HVAC Equipment and Getting It Installed Properly
How well a new HVAC system performs, and how much it costs, depends heavily on its design and the quality of installation. It’s important to make the right decisions—and there are many to make. You also must make sure to get a fair contract.

If you are installing new equipment, in addition to making choices about energy efficiency, you will need to decide whether to pay extra for various features. Here is a summary of the types of add-ons.
Maintaining Your HVAC Equipment
The most important maintenance task for HVAC systems is something you can do yourself—replacing the air filter. Check your filter monthly. When a filter has a matting of dirt—i.e., it’s difficult to see through when you hold it up to a light—it’s time to replace it.
HVAC Maintenance Contracts Are Usually Bad Buys
Rather than paying for individual maintenance visits and repair jobs, you might consider getting a service contract for air-conditioning and/or heating equipment. Many companies try to persuade customers to enter into such contracts.
