Updating Your HVAC Unit

Preparing For An AC Installation

Proper installation of an AC system can mean the difference between a long and maintenance-free life and one that is plagued by problems and excessive energy costs. While performing the installation itself is important, there is a great deal of initial preparation that should be performed as well. These steps are necessary whether you are having an entirely new HVAC system installed or simply upgrading or replacing an old one.

Match Existing Equipment

If you are replacing an old or failed system, then it is important to match replacement equipment with any equipment that you are reusing. If the outdoor unit has failed, for example, then it may be difficult to replace it with another identical unit. It may sometimes be cost-effective to simply replace the compressor or other failed part, but a single failed unit is often enough justification for an entirely new system. This might seem excessive, but remember that the still-operating portions of your HVAC system have just as much wear as the failed component.

Closely Examine Reused Equipment

If some of your existing system will be used for the new installation, then it is important to carefully examine this old equipment. Old line sets are often kept if they meet the specifications required by the new units, but copper refrigerant lines can easily suffer damage from collisions or simply from corrosion over time. Many technicians will choose to replace line sets out of an abundance of caution, but if yours are being reused, then they must be thoroughly inspected for any signs of damage.

Inspect and Test Ductwork

Whether you have ductwork already installed from an old AC system or a forced-air heating system, it is important that the ductwork is inspected and tested before installing a new air conditioner. It's important that your ductwork is clean and in good condition, but it is vital that your existing ductwork is properly sized for the new system. The size of your ductwork is more important than you might expect, and improperly sized ducting can lead to your AC system overworking itself, running inefficiently, and wearing out faster. Ductwork should also be tested for leaks or other signs of damage.

Check the Electrical System

Your home's electrical system must be capable of handling the load of your new AC unit. Depending on your current service, it may be necessary to upgrade or to add an additional panel to your circuit breaker. An experienced contractor should be able to judge whether your current electrical system is sufficient for your new AC system and recommend upgrades as needed.

A good technician will perform all of these preparation steps and many more. Completing the proper prep work before beginning installation is the best way to guarantee that your AC installation is successful and hassle-free. To learn more, contact a company like Bergmann Heating & Air Conditioning.
