7 Considerations for Choosing a Commercial HVAC System

Office buildings, warehouses, factories, medical centers and other businesses need to have an adequate commercial HVAC system. Making the right choices while planning for a system’s installation can lead to an improved comfort level within the space and lower monthly utility bills. The following considerations will help you choose a commercial HVAC system in Walnut, CA:


Commercial HVAC systems can get large, but that doesn’t mean picking the biggest option available is best. You’ll need to choose a unit that fits in the utility room or on the roof of the building, depending on where you plan to have it installed. Based on the type of system, commercial units also require space for ductwork and drainage systems.

It’s essential to choose a unit that’s the appropriate size for the needs of the building. Commercial HVAC systems produce a certain number of British Thermal Units (BTUs) that indicate their power. The higher the BTUs, the better the system can be for a large space.

There are a number of factors, including square footage, that determine the appropriate size for a commercial HVAC unit. A split system can allow different tenants to control the temperature within their space, even if they have different preferences.


HVAC systems have an efficiency rating known as SEER (Seasonal Energy Efficiency Ratio) that indicates how efficiently the system operates. A higher SEER rating means higher efficiency.

A ductless mini-split system is one of the most efficient HVAC options. It’s not only an effective way to heat and cool a building, but there’s also no need to lay out and install ductwork. The system helps provide good air quality, and it’s usually easy to maintain since there’s no ductwork involved.


HVAC systems can last up to 25 years when adequately maintained. The longer the unit operates properly, the longer the business can put off paying for a replacement. High-efficiency units tend to last the longest, as they put less strain on the device by using less energy.

Indoor Air Quality

Poor indoor air quality (IAQ) could lead to unwell employees who call out of work. Employees who feel good tend to show up for work and be more productive. Choose a system with a high-quality air filter or a ductless system to promote healthy air in the office.


Every business operates on a budget. The price of the new commercial HVAC unit can play a big part in which one is best for the company. Comparing features with costs and getting recommendations from a certified HVAC comfort advisor can help with the process.


Ideally, your HVAC system will last as long as expected, but that’s not always the case. Due to various preventable and unpreventable circumstances, there’s no telling how long its lifespan will be. Having a good warranty may help cover the cost of repairs.

All HVAC manufacturers provide a warranty, but some are better than others. Additionally, some manufacturers have a better reputation for honoring claims.

Doing research can help you determine which company could be a viable option for your business. Keep in mind that the HVAC unit needs a licensed HVAC comfort advisor to install it properly for the warranty to remain valid.


Gather detailed, itemized quotes from each HVAC company you speak to. Prioritize value over savings, and be wary of companies who underquote to earn your business only to add to the bill later or who tell you they can’t give you itemized quotes.

You’ll also want to pick a company that aligns with your time frame. Some can offer quicker results, while others will have you waiting a while for your commercial HVAC unit.

The size, efficiency and cost of a new commercial HVAC unit are only some of the considerations to think about. Contact Metz Air Control when you need commercial HVAC services in Walnut, CA. We can help you choose the best option for your business.
