Things to consider before retrofitting

Decreasing both the operating and maintenance costs, is the main reason for retrofitting and ultimately improe the current HVAC system. When we increase the energy-saving efficiency, we are mainly reducing the costs involved with respect to operation and maintenance.

You should evaluate beforehand whether to go ahead and upgrade or replace parts of an HVAC system, because these mechanical systems are quite large and are almost at times instegrated with the building's structure. Therefore, the owners and property managers should look to external sources for assistance when determining retrofitting decisions because it could be a complex procedure and also look for guidence while coming up with a retrofit design.

You should evaluate your current HVAC system before determining whether a restrofit will be the best course of action and also identify the bad performing components before implementing a retrofit. You can do a baseline assessment in order to measure the system's performance against desired performance rates. But, for more difficult parts of the HVAC, you may need a specialist engineer.

Another very important thing to consider is the size of the system since it relates to its effectiveness when managing temperature. A smaller unit will use less energy but may not be suitable in regulating tempreture levels for a large area. In order to get this resolved, you may want to go ahead with a larger system which in turn would be more effective in controlling tempreture but it will use more energy. You should always consider the sizes which will be suitable for corresponding areas.

When HVAC service providers calculate the estimate, they would take into account the technical requirements for a system to function depending on the size of the area it's meant to regulate. You may consider contacting the service provider who installed your current system in order to check whether or not they have that information available. If the building where the system is installed has gone through any architectural changes, new estimate would be calculated since the change will affect the system's coverage.

You would also need to consider the operating conditions of the builing at the time of choosing a replacement system or even for the parts. Whenever there's more people occupying a space, the system has to deal with the extra heat. Hence, the compressor which is in the HVAC system must be be suited to the changeability of the HVAC system’s operating conditions. You would also need to install a correct compressor based on the changes in conditions in the affected area.
