Commercial building HVAC is one of, if not the, largest consumer of energy in just about every commercial building. As a result the commercial building HVAC system is a big part of helping designers and architects meet net zero energy goals.

Commercial building HVAC and lighting at typically responsible for most of the energy costs in running a building, so when technological improvements can be made it’s a big deal. While many in the public view green buildings and net zero buildings as an environmentally responsible choice, building owners also see it as a good business decision.

Approximately 40% of the energy in commercial buildings is allocated to HVAC equipment, so it’s easy to see that finding efficiencies in the mechanical systems of the boilers, air conditioners and other components is beneficial. In terms of achieving any sort of LEED or net zero status finding these efficiencies is essential.

A high-efficiency commercial building HVAC system uses innovative technologies, such as inverters that drive the compressor and smart controls to manage time and usage. Essentially, every watt that can be saved in HVAC, lighting and other areas that doesn’t have to be generated by renewable energy makes achieving designations easier. Many net-zero-energy buildings avoid the direct usage of fossil fuels and install heat pumps when applicable. The electrification of heating through via heat pumps and the electrification of transportation via electric vehicles are common net-zero-energy building components.

The size and energy consumption of the HVAC systems also directly relate to key building design features such as orientation, building envelope, lighting system, and appliances. By starting with the HVAC system, since it’s the largest energy hog, it’s easier to configure other systems in order to minimize overall energy consumption.

Much of this is done prior to construction in the planning stages, but it’s also important to properly maintain and repair commercial building HVAC components regularly.

We hope you liked Part 1 of our commercial HVAC FAQs. Some of our customers have found them very useful in understanding their commercial HVAC system. Here’s part 2:

Q: Is it safe to run the commercial HVAC with contractors working on the finishings?

A: It depends on which finishings are being installed. If a drywall contractor is working in the building they will be producing an exceptional amount of dust that could be drawn into the duct system. Overall, construction sites have lots of airborne dust and debris. If you turn on your commercial HVAC system while contractors who make lots of dust are still working you will have problems that can be costly. Use a temporary heating and cooling option while construction is taking place.

 

Q: I’ve just bought a building and the HVAC system is noisy. What’s the problem?

A: If the commercial HVAC system in your building hasn’t been properly installed there can be a number of reasons for the noise. Most glaringly building ductwork is one of the most common places where noise originates from. Ductwork has the ability to function like large speaker tubes that allow noise to travel throughout the building. Airflow doesn’t have an impact on the sound so shutting your system off might not have any affect. Holes in your ductwork might also be the reason for the noise. The easiest way to find the source of the problem is to contact a reputable and professional commercial HVAC technician from Commercial HVAC. With over 30 years of experience in the commercial HVAC industry they’ll easily find the source of the noise in your building’s HVAC system.

Q: I’m worried about mold in my building. How can it be avoided?

A: Moisture is the source of mold, so controlling moisture in your building is the best way to prevent mold. One of the primary functions of your commercial HVAC system is to control moisture in the air and effectively remove it to help prevent mold from forming. Keeping your system properly maintained is ideal and will ensure that moisture is controlled, but if there is excess water in your building it needs to be manually removed. Your commercial HVAC system can only do so much and if your roof is leaking or water is entering your building from somewhere else then you may need to take other measures.

The solution to mold isn’t replacing your ductwork or rooftop HVAC unit. Contact a HVAC technician if you suspect you have a mold problem. They’re the best people to help you understand if your system is part of the problem.

We get lots of questions from our commercial HVAC customers every time we visit for a HVAC maintenance or a HVAC repair appointment. Here are some of the most common questions with answers that we hope are helpful to our customers.

Q: How does my commercial HVAC system move air through my building?

A: There are fans that draw air in through returns, which look like grilles. This air is then forced through ductwork in your building that fills the building with conditioned air through the registers in the various rooms on all floors. This process is continuous and helps regulate the temperature and moisture levels in your building.

Q: How is the commercial HVAC duct system built and installed?

A: The duct system is most buildings is installed when the building is first constructed. It’s designed and installed by commercial HVAC professionals like Commercial HVAC that have years of experience and know the rules and regulations of the commercial HVAC industry. The ducts are made of sheet metal and installed by sheet metal workers and HVAC technicians.

Q: What should I be weary of when it comes to the design and installation of ductwork?

A: When ductwork isn’t installed, sealed, or built properly it can leak and divert excessive amounts of air to the wrong places. This can not only reduce the efficiency of a system, but also create necessary and excessive noise throughout the building. If ductwork is installed to soon during construction it can be much dirtier than it should be and can be expensive to clean out once construction is finished.

Q: How can duct leakage be reduced?

A: If a building is being constructed then it’s important for the builder to adhere to the provincial rules and regulations surrounding commercial HVAC installation to ensure your ductwork is built, installed and sealed correctly.

Q: Who can help me evaluate, adjust and inform me of the condition of my ductwork?

A: At Commercial HVAC we regularly work on commercial HVAC projects with a number of customers in Toronto, York Region and throughout the GTA. We have over 30 years of experience working with commercial HVAC and ductwork. We’ll be happy to help you understand your duct system and help you ensure its serving your building to the best of its ability.

Q: The energy bills are high in my building and tenants are uncomfortable. Is there a HVAC problem?

A: There are a number of things that could be causing these issues. There could be problems with your duct system, your rooftop unit might be rapidly aging, you boiler might need maintenance or replacing, or any number of other problems. The best way to find out what’s wrong and to get it fixed quickly is to call Commercial HVAC: 416-727-5016.

A commercial HVAC system is a very large long-term investment and in order to remain a good investment it requires proper maintenance and repairs. Without proper servicing on a regular basis a commercial HVAC system can slowly cost more and more and ultimately small problems will become large problems and large expenses. Here are 5 tips to keep your commercial HVAC system running properly and efficiently.

  1. Cooling Maintenance Scheduling: When hot weather is waning and cold weather is on the horizon it’s the best time to take are of your commercial HVAC system cooling components. Scheduling commercial air conditioner system maintenance during the fall winter or spring, off-peak times, ensures that HVAC technicians will have no problems taking care of and maintenance and repairs. Additionally, if they need to order parts and wait a day or two for them to arrive it won’t be a major issue as the cooling system isn’t being relied on during colder weather. Winter maintenance of the cooling system also means that it will be ready to go when the warm weather arrives, so there is a lower chance of a breakdown during the summer months.
  2. Preventative Maintenance of a Commercial HVAC System: Preventative maintenance is one of the best ways to save money when it comes to a commercial HVAC system. Routine maintenance is essential to ensuring the efficiency and reliability of all commercial HVAC system components. It’s also a great way to discover small issues that can be repaired before they become larger problems. Regular maintenance also allows building owners and property managers the ability to budget for upcoming repairs and defer any repairs that can wait in order to stay on budget.
  3. Don’t Put Off A Full Replacement: While replacing a rooftop commercial HVAC system is a big initial expense it’s important to weigh the expense of ongoing repairs and maintenance of an older system against it. A new Energy Star commercial HVAC system will not only save you money with better performance than an older system, but also on maintenance and repair bills. Retrofitting an existing system is also an option in terms of improving efficiency and reducing maintenance and repair costs.
  4. Clean Condenser Coils: Dirty condenser coils are a major contributor to rooftop commercial HVAC system damage. Regular cleaning prevents the degradation of the cooling system and can save up to 30% on energy bills and repair costs over a 20 year period. Simple power washing is the best way to clear any debris or dirt off of the condenser coils.
  5. Change Filters: Manufacturer recommendations about how often commercial HVAC system filters should be changed is the best guide to know how often this action should be taken. In the spring and fall filters should be changed more often than usual as there is more dust, debris and other particles in the air that can quickly clog filters and affect performance.

The newer your boiler is the easier it is to properly maintain. Newer designs take into account years of research and experience in order to provide better boilers to commercial buildings, but that doesn’t mean they don’t require winter commercial boiler maintenance. Commercial boilers are an important part of the proper operation of your building and as a result they need to be professionally maintained. When winter arrives you will be relying on your boiler for everyday heat in addition to hot water services, which puts additional pressure on your boiler to perform. A properly working boiler is one that operates effectively, safely, and efficiently.

Why Perform Commercial Boiler Maintenance?

Any mechanical system in your building will wear down over time and in order to prevent a serious breakdown or replacement it’s important to perform regular maintenance. When your boiler starts wearing down you’ll notice a significant drop in performance and even an increase in your energy bills as your boiler works harder to do the same job it did a few months ago. If boiler components aren’t working properly or configured to be as efficient as possible they may be sustaining damage or causing damage to other components.

Winter Commercial Boiler Maintenance by Commercial HVAC

There are certain low-level fixes and maintenance tasks that can be and should be taken care of on a regular basis by a building maintenance team or building manager. These tasks are typically not too technical and don’t require any certifications outside of what building maintenance personnel already have. Aside from these general tasks any winter commercial boiler maintenance should be conducted by a reputable and properly trained HVAC technician like the ones at Commercial HVAC. Commercial HVAC technicians are trained and licensed professionals who regularly maintain commercial boilers and are very familiar with their proper operation. Additionally, a Commercial HVAC technician can identify existing and potential problems and make recommendations for servicing, configurations, repairs, and replacements.

What Takes Place During Winter Commercial Boiler Maintenance?

A professional boiler maintenance inspection ensures the proper functioning of your boiler. A Commercial HVAC technician will find all problems with your commercial boiler, adjust all the working components for efficiency, and provide you with a report surrounding the short-term and long-term maintenance requirements of your boiler. At the very least boiler maintenance should be done at least once each year. We recommend winter commercial boiler maintenance because the timing ensure your boiler is ready to perform when you need it most.
