Commercial AC Services Houston

Commercial and residential HVAC systems work toward the same goal, keeping business and homes comfortable, regardless of the conditions outside. While the concept of central heating has existed since the days of the Roman empire, it has only been a little over a century since the first commercial air conditioning system was installed. 

In 1902, Willis Carrier designed the first commercial air conditioning system for use in a book printing plant. This early system aimed to keep humidity from damaging the books, not necessarily for the comfort of the occupants. It wouldn’t become an option for residential use until the invention of the in-window air conditioner in 1931.  

Since then, air conditioning systems have allowed areas of the country that were considered too hot to live comfortably to swell in population. Imagine how unforgiving summer in Houston would be without the modern comfort and convenience of air conditioning.


Most of the differences between these two types of systems arise from the simple fact that commercial HVAC systems are much larger than residential HVAC systems. Commercial HVAC systems are designed to serve sizable buildings and significant numbers of people, which requires extensive and complex system architecture compared to the relative simplicity and small size of residential systems. As a result, technicians who perform work on commercial HVAC systems need to have training and experience specific to commercial work.


Commercial HVAC units are almost always installed on the building roof for a couple of reasons. The first reason is the amount of real estate that an AC system can occupy, as the largest HVAC units can be a small house. By installing AC units on the roof, businesses can free up more parking, warehousing, or office space. A bonus to rooftop HVAC installation is that the unit’s noise is isolated to the roof, and not next to a conference room window. 


Residential HVAC systems need to cool much smaller areas that are designed and insulated with comfort in mind. Many commercial HVAC systems will consist of multiple AC units to cool specific areas of the building. Additionally, the various parts and components used in commercial HVAC are larger than those used in residential units. 


Apart from their size, residential and commercial HVAC systems also vary in structure. Commercial systems need to be more adaptable depending on the type of building where they are being installed, the number of occupants, and the building’s use, whether it is periodic or constant. 

Other factors that determine the complexity of commercial HVAC systems are the end-use of the structure and the things manufactured or sold in the building. These are the significant reasons commercial systems feature a more complicated mechanism than residential units that require less power to alleviate exhaust.


Commercial HVAC systems require more frequent and consistent maintenance than residential units. Filters require changing, refrigerant levels need to be monitored and adjusted, and the system needs to be checked out for wear and tear of mechanical parts. Performing regular maintenance can alert the business owner to potential issues with their HVAC systems that may result in a unit’s complete failure. 

For buildings with large HVAC systems with multiple zones, blowers, and chillers, keeping up with HVAC maintenance can seem like a full-time job. Commercial HVAC companies, like Nick’s Plumbing & Air Conditioning, offer customers a regular maintenance schedule that covers your system year-round. 


Having an HVAC system that is adequately sized to your commercial building is essential to provide your business’s comfort and efficiency. HVAC systems that are too small will struggle to keep up with the demand for cooling, running for extended cycles, yet never getting the temperature down sufficiently. Too small of a unit can also leave the building overly humid, as there is too much moisture for the system to remove efficiently. 

This might lead you to think that installing an over-sized HVAC system would be a good thing, and you would be wrong. HVAC systems that are too big for their own good will cause your system to cycle off and on frequently, wasting energy and causing moving parts to wear out sooner. 


If lowering energy costs, helping to prevent excessive wear and tear, and extending your commercial HVAC system’s lifespan is your goal, regular maintenance is essential. Nick’s Plumbing & Air Conditioning technicians can work with you to create and implement an HVAC maintenance schedule that works best for you. 


Heating, ventilation, and air conditioning systems need to be in peak mechanical shape to answer the demand on them. It can’t be stressed enough to make sure you’re installing the properly sized system into your commercial building. 

Modify the HVAC ductwork in your building to eliminate 45-and 90-degree angles and to cut-off the flow of treated air from unused rooms. Have the entire span of your ductwork checked for any air leaks that could draw in warm air, requiring the system to work harder. Check all windows and door jambs for drafts and seal any existing leaks. 

When choosing a commercial HVAC company, it’s essential to work with a service provider with experience and industry longevity. Look for a contractor that emphasizes customer satisfaction by delivering exceptional HVAC performance and efficiency every time. That’s the goal of Nick’s Plumbing & Air Conditioning Services.

I called Nick’s Plumbing to complete a natural gas line replace and repair job after being frustrated with the incompetence of the supposed “expert” plumbers in West University Place. Nick’s employees were knowledgeable, friendly, and professional. They finished a job in a day that the prior company could not complete in a week – and at a much lower cost. Many thanks!

Called on Saturday around 11 am and they were onsite within an hour to help get our domestic pumps up and running for 200+ apartment homes. Fantastic service, communication, and personnel. Pricing was very reasonable too.
