Methods for Avoiding Problems with HVAC Upgrades

Being a facility manager is hard enough without having to repair or replace a building’s HVAC system. While many HVAC upgrades go smoothly, there is always the chance that upgrading the building’s system will be riddled with issues. While there is no way to predict the outcome of a project, paying attention to all the details can help to avoid some of the major problems that may arise.

Understand the Cause of the Problem

When the building’s heating and cooling system aren’t functioning properly, there may be pressure to simply replace the malfunctioning system. While a complete system replacement is an option, it is important to know why the system isn’t working properly. Once you know what is causing the HVAC system’s performance issues will you be able to know if the entire system needs to be replaced or if repairs can fix the issue.

Get it in Writing

One problem that can cost you is a lack of or conflicting documentation. In order to review problems later on, change orders, design alterations, equipment substitutions, and programming revisions need to be put into writing. This is the only way to keep everyone involved in the HVAC upgrades process accountable.

Get the Proper Plans and Specifications for HVAC Upgrades

When working on upgrading a building’s HVAC system you need to make sure you have the proper plans and specifications for the system you are installing. You want to ensure that the system you have chosen meets the requirements and specifications that you have laid out for the building. By having the plans and system specifications in writing you will know what should be happening and which items should be included in the install.

Planning HVAC upgrades for a building takes a lot of forethought and attention to detail. While there is no guarantee the upgrade process will run smoothly, there are a few things you can do to help avoid some of the more common problems that may arise during the process.

New Technologies for HVAC Systems

Commercial HVAC systems are expensive to run. Critical to keeping the occupants of a building comfortable, they have become unavoidable. The older heating and air conditioning units use a considerable amount of energy to operate. In fact, they account for more than half of the entire energy consumption of a commercial building. The good news is there are a number of energy saving technologies on the market today to help cut the costs associated with the use of commercial HVAC systems.

New Technologies

  • Demand Control Ventilation – this technology combines carbon dioxide sensors with economizers in order to sustain air levels within a suitable range while preventing over ventilation.
  • Dedicated Outdoor Air Systems – conditions outdoor makeup air, or the outdoor air that hasn’t been recirculated, independently from indoor return air improving humidity control.
  • Displacement Ventilation – improves indoor air quality by using a low speed stream of cold, fresh outdoor air that is supplied at the floor level of the building. This action displaces the stale air that accumulates at ceiling height which is vented from the building. The continued circulation keeps the air clean.
  • Micro Environments – creates a virtual zone for occupant environmental control. Using an online interface, each occupant within the building is able to control the temperatures within their own areas increasing staff comfort and productivity.
  • Variable Flow Volume Systems – a ductless system that is flexible in capacity and design. They use multiple compressors and provide partial-load performance as well as zoned temperature control.

These new technologies can provide a significant reduction in energy used, which will result in cost savings. They are not appropriate for all situations. The best things to do is talk to a knowledgeable contractor to find out if any of these solutions would be right for you.

HVAC Efficiency: Systems for Better Cost Savings

HVAC Efficiency is key for saving money on your heating and cooling costs.

HVAC Efficiency: Systems for Better Cost Savings


When temperatures begin to soar, your HVAC efficiency is put to the test. As the system works to keep your house cool, it can begin to wear down and need repairs. The harder your HVAC system has to work, the less efficient it becomes and the more energy it needs to operate. When your HVAC system becomes less efficient and it starts costing you more money to keep your house cool, it may be time to start looking at some options.

HVAC systems are expensive, complicated and aren’t immune to wear and tear. If you’ve noticed an increase in your energy bill, you may need to call a technician and have your HVAC system serviced. By servicing your HVAC and taking care of any minor repairs that may arise, you can cut your energy costs by up to 20 percent, according to the EPA.

There are times however, when repairing the system isn’t an option.

HVAC Efficiency Considerations when Buying a New System

If you find yourself needing to purchase a new HVAC system, keep the following in mind:

  • Find a system with the USEPA’s Energy Star Seal.
  • Purchase the model with the best HVAC efficiency for your needs if the Energy Star doesn’t rate an option you require.
  • Look for other energy-saving features such as a programmable thermostat and power-saving functions.
  • Look for equipment that uses as little energy as possible while in the “off” mode.

When the temperatures are scorching and you want to cool your house down in a hurry, you want a HVAC system that is operating at top performance. If you are not able to keep your house cool or you notice your energy bill is rising, it may be time to make repairs or replace your system all together.
