How to Keep Mold out of Your Workplace HVAC System

Mold is a dreaded contaminant for home and business alike. Just the hint of mold in your HVAC system probably makes you nervous. Clean up requires skilled professionals and it can cost a lot to make sure every last bit is gone. Instead of facing that situation, you can take preventative steps to keep mold out of your HVAC and out of the air you and your employees breathe.

Rely on Professional HVAC Installation and Maintenance

If an HVAC system is not installed well, if corners are cut, you could be facing a situation in which mold-growth is inevitable. Poor installation can mean leaks and misuse of insulation and sealants to keep moisture out of the system. The equipment that gets installed can also be a source of mold, so be sure a professional is taking care of your installation and inspects every piece before it goes in.

Keep an Eye on Ducts

No matter where the mold may be growing within your HVAC system, it is the ducts that spread it around and make your workplace dangerous for you and your workers. It’s important to check the ducts and vents regularly to be sure there is no mold growth. You want to catch it early if it happens.

Mold Loves Moisture, So Keep it Dry

Keeping your HVAC system and surrounding environment dry is so important in keeping mold at bay. It thrives in warm, wet places. Have someone inspect your building for cracks and gaps in sealants or insulation. These are places where outdoors moisture could be getting into the system. If you do have excess moisture, consider using a dehumidifier to pull that water out of the air.

Rely on Professional Remediation Sooner Rather than Later

If it happens, if you find mold somewhere in your workplace HVAC system, don’t ignore it. You will need to have it professionally remediated and the sooner you do it the better. A small mess is easier and cheaper to clean up than a big one, so meet it head on, take care of it, and then be sure you eliminate any problems, like leaks, that led to the mold growth in the first place.

Mold can be a serious problem, which is why it’s better to head it off with prevention rather than cleaning it up after it has gotten out of control. You can take some very simple steps to prevent mold growth in your workplace HVAC, but if it does show up, be sure to get it removed as soon as possible. If you don’t feel comfortable taking some of these steps by yourself, contact our experts at Canoga Park Heating and Air Conditioning to get you started.

The Major Differences Between Commercial and Residential HVAC Systems

While residential and commercial HVAC systems have similar methods of heating and cooling, there are significant differences between the two types of systems. Therefore, when you need to get your HVAC system repaired, you’ll want to choose a technician who specializes in the type of service you need.


Residential HVAC systems are located on the ground near the home. Commercial systems, on the other hand, generally reside on the roof of the commercial building. Commercial HVAC systems are usually quite larger than residential ones, and the rooftop provides ample space for each part of the unit. The rooftop location also allows technicians to work on these systems without disrupting those inside the building, and it keeps the system safe from interference and vandalism.

Packaged vs. Splits

Residential HVAC systems are generally in splits. The unit inside the home houses the blower, evaporator and condensate drainage, while the unit outside the home houses the compressor, condenser and condenser fan. Commercial systems, by comparison, are in one complete package inside of a single cabinet. Only the ducts and zone dampers are inside the building, while the rest of the system remains outside.

Modular vs. Standalone

Units installed in a residential space are standalone and can’t be built upon. Both the outdoor and indoor units need to work together, and the entire system must be replaced if significant changes need to be made to the heating and cooling. Commercial systems are modular, which means they can be altered as needed. Technicians can add onto the modular units, and they can also transport these smaller segments more easily, as the system itself is quite a bit larger than a residential unit.


Unsurprisingly, commercial HVAC systems are much more complex. They heat and cool larger indoor areas, and as a result, the drainage system requires more parts than that of a residential system. Residential units generally only have one condensation pan that drains to the outside, and they have windows to alleviate exhaust. Commercial systems have detailed drainage systems, as well as additional components to help with exhaust functions.

When you need to get your HVAC system repaired or serviced, choose the appropriate type of company and technician. While HVAC systems in both residential and commercial spaces perform the same functions, they do so in different ways.

How Can You Control Your Business HVAC Costs?

HVAC costs can be a huge expense for businesses and large facilities, but there are many no-cost and low cost ways to increase HVAC efficiency and lower your energy bills. Some may require a bit of effort, but all of them should help you to save money in the long run.

Ways To Control Your HVAC Costs

Programmable Thermostats Help Avoid Wasted Energy

If your building’s HVAC system is connected to a standard thermostat, upgrading to a programmable thermostat can make a huge difference. These thermostats allow you to program temperature setbacks so that your system is not operating during off-hours. They may also allow you to program a wider range of allowable temperatures, so that areas where climate control is not so important may grow warmer or cooler than other areas without engaging the HVAC system.

Avoid Heating Or Cooling Loss Through Pipes, Ducts And Dampers

Another inexpensive—although potentially labor-intensive way to increase your HVAC efficiency, is to make sure pipes and ducts are well-insulated where necessary. Replace damaged insulation with higher efficiency material, and make sure all ducts and pipes that pass through unheated areas are all covered with high-quality insulation.

Heated or cooled air can also escape through dampers that are left open or do not seal properly. Inexpensive edge seals made from flexible plastic can help dampers to regain their air-tightness if dampers have begun to wear down with age.

Make Outside Air Work For You

In areas with the right climate, taking advantage of outside air to help cool a facility is a great way to reduce energy costs. Night cooling is often an economical choice in places where off-peak energy rates are very cheap and where the nighttime air is cool and dry. Economizer cycles can also take advantage of a favorable climate by replacing recirculating air with outside air whenever the outside air is significantly cooler and drier than the return air.

When using outside air, facilities may waste money by over-conditioning. To avoid this, keep humidity settings relatively low in winter and relatively high in summer. This way, you keep your HVAC system from having to work overtime to add moisture to dry air and remove it from humid air. The air should still be comfortable for its occupants at these wider ranges of humidity; in fact, you may find that you are able to turn off winter humidification entirely without anyone noticing or caring.

The most efficient ways to control HVAC costs can vary depending on the type of facility you manage and the climate in which you operate.

What Are The Different Types Of Commercial Heating Systems?

If you are preparing to install a new or replacement commercial heating system, there are several important factors to keep in mind. Cost is always important, but savvy business owners will consider the cost of use and repair in addition to the installation price tag. The efficiency and environmental impact of differing commercial HVAC systems may also influence your decision.

Different Types Of Commercial Heating Systems

To help you get started, we have provided a brief introduction to the different types of commercial heating systems available to you.

Oil Or Gas Steam Heating Systems

The oil or gas steam heating system is one of the oldest ways to provide central heating to a commercial property. These systems use oil or gas fuel to boil and condense steam and then pass it through pipes. While it may be the elder statesman of commercial heating systems, this type of system hasn’t aged particularly well. Not only is it relatively inefficient in its use of energy, but it works slowly to heat a property because the steam has to boil and condense before heat can begin to circulate.

Gas Or Oil Water Heating Systems

Like steam heating systems, water heating systems rely on a boiler powered by oil or gas. The similarities don’t end there: like steam heating systems, water heating systems are relatively inefficient and slow compared to other commercial heating options. In water heating systems, the boiler heats the water, which is then passed through radiators located throughout the building. The air in the system has to clear each time you turn on the heat, which wastes energy and adds time to the heating process.

Natural Energy Systems

Natural energy systems that use solar power, geothermal energy or other sustainable resources are great environmentally-friendly options. In addition, these systems are often more cost-efficient over a long period of time than oil or gas powered systems. Unfortunately, natural energy heating systems have a relatively high cost of installation, and are often reserved for larger businesses.

Heat Pump Systems

Heat pump systems essentially work like a refrigerator in reverse, extracting heat from the air and circulating it throughout a property. Since these systems don’t rely on a fuel source, they are extremely energy efficient and usually very cost efficient as well. Heat pumps require electric back-up heaters in case the temperature gets too cold to extract heat, and these systems may become uneconomic in places with below-average winter temperatures.

Myths About Commercial HVAC Companies

There are various misconceptions that some people hold about heating and cooling companies. Such include the assumption that a large commercial HVAC company would provide better services and is therefore better. Those who’ve had sour experiences with larger firms will know that this isn’t necessarily true. However, it may be difficult for one to understand why. There are also other things that need to be noted.

The Bigger The Company; the Better The Service

One may be tempted into thinking that big companies do everything right. This could be due to the idea advertised by such firms that they offer better service because they have more technicians. This means more hands on the clients’ equipment.

Typically, expertise about HVAC systems doesn’t flow freely in larger firms. The best firms are those that offer the same service each time they handle a client’s equipment, regardless of their company size. This means that an experienced professional assumes long-term personal responsibility for the particular unit.

All Commercial HVAC Companies Perform Tune Ups The Same Way

Most firms view a tune-up as an opportunity to look for other issues to address as they replace the filter, so that they can bill the client more. The key is finding a firm that views tune-up as precautionary maintenance, which means proactively dealing with issues before they can happen. Though this may cost more in the short term, it will be worthwhile as time goes by.

All Commercial HVAC Firms Generate Income Similarly

A typical HVAC company makes most of its money on replacements and repairs, with maintenance being a supplementary source. A good idea is to find a firm whose structure is different. A company whose business model is focused on profitable maintenance calls will actually need its maintenance to work. As such, it would make sense if the client’s equipment is maintained often.

New Equipment Doesn’t Need Maintenance

Every manufacturer asserts that maintenance is necessary to preserve the equipment’s warranty. If the client fails to schedule maintenance properly and some parts fail within the warranty period, they’ll end up paying for replacements and labor to fix the unit. Proper maintenance could also extend the unit’s life by about 30%.

Keep Your Commercial HVAC System Running Properly

A Commercial HVAC system is a huge investment that require proper care in order to work efficiently. Neglecting your HVAC system will increase your energy cost and reduce your unit’s life span. Here are some tips on how to take care of your commercial HVAC system.

Take Advantage of Off-peak Season

Most people wait until peak season to perform maintenance on their HVAC units. During this time, there is a higher demand for technicians, and the cost for this service tends to go up. A good way to go about this would be scheduling your cooling maintenance during winter. This way, when summer sets in, you won’t have much to worry about as far as emergency repair is concerned.

Preventive Commercial HVAC System Maintenance

Most people neglect servicing their units simply because it still “runs”. However, waiting until your unit breaks down to take action can be costly in more ways than one. For starters, worn out components in your system will not only increase energy cost but also interfere with indoor air quality. Regular maintenance ensures your unit continues cleaning your air, while reducing energy costs.

Replacement Vs Repair

In some cases, replacing a worn out HVAC system is the best option. If you feel like you are spending more money than you should on HVAC repairs, then you might want to consider upgrading your system. Newer systems are more energy efficient and come with state-of-the-art features that make your life more comfortable.

Clean Condenser Coils

Dirt and debris will accumulate inside your system as time goes by. Dirty coils will not only interfere with regular performance, but will also reduce the life of the unit. You will save yourself a lot of money and trouble by simply cleaning your condenser coils every few months. The process is fairly easy and won’t take much of your time.

Replace Air Filter

Air filters are responsible for catching dust and other debris present in your air. Depending on the type of air filter you are using, you’ll need to replace them every few weeks or months. Going for the high quality filters might cost you more to purchase, but will save you a lot of money on maintenance in the long run.

Tips For Hiring A Commercial HVAC Contractor

Whether you want an HVAC system designed for your commercial establishment or an existing system repaired, it is crucial you hire the best HVAC contractor you can afford. Hiring a commercial HVAC contractor can be challenging since there are many service providers in the industry. At Canoga Park Heating and Air Conditioning, we understand that you may have a hard time hiring a contractor, so here are some tips to help you out.

Before You Hire a Commercial HVAC Contractor:

Ask friends, colleagues, relatives and neighbors to give you referrals to contractors they have worked with in the past. If they had a great experience with the HVAC contractor, chances are high you will have a similar experience. This is the quickest and most convenient way of finding a great commercial heating, ventilation and cooling contractor. You can use these referrals to make a shortlist.

Next, ask for references from the contractors on your shortlist. These are simply names and contact details of previous clients. Be sure to call them to learn about the quality of service offered by the contractor. A long list of satisfied customers shows the contractor is able to meet or even exceed customer expectations.

Ask the contractor to provide proof of insurance and bonding as well as their license to find out if they are a licensed contractor. Be sure to check with both state and local authorities for the minimum requirements regarding these issues.

Get quotes from several contractors and compare the estimates. Ideally, those estimates should be in writing. While some contractors many not be willing to offer free estimates, serious contractors are always willing to do so.

Ask for onsite inspection of the project. This will help the contractor to prepare a more accurate bid, which is backed by accurate information.

Negotiate project timelines. Be sure to have all the details you have agreed on with the contractor written on paper and signed by both parties.

We recommend you invest in high performance HVAC equipment after getting the necessary paperwork signed. The equipment should also be sized appropriately; it should not be too large or too small for the commercial space.

Energy Saving Technologies For Your Business

Energy Saving Technologies

Canoga Park Heating and Air Conditioning appreciates the fact that heating, ventilation and air conditioning accounts for over 50 percent of your energy bill. In a bid to help businesses to minimize their energy consumption and increase their energy savings, we can implement any of the following energy saving technologies:

Thermal Energy Storage

In commercial establishments, the electricity tariff is designed in such a way that the cost per unit during peak hours (normal working hours) is much higher than off-peak rates. We can help you implement a thermal energy storage technology that makes use of affordable electricity at night and stores the cooling energy for use during peak hours, when the unit cost of electricity is highest. This is done by freezing water at night. During normal working hours, the chilled water or ice is used to cool the business premise. The energy savings attributed to thermal energy storage can be quite significant, so every business owner needs to consider implementing the technology.

Adjustable Speed Drives (ASD)

Speed drives are sophisticated electronic devices designed to control the speed of motors based on user settings, programmed instructions or demand. When your HVAC needs are minimal, the ASD can reduce the speed of blower and fan motors. The latest HVAC systems come with ASD technology. If you have an older system, however, we can help you install ASD’s.

Desiccant Dehumidification

We know that cooling humid air is an energy-intensive process that can increase your utility bills. Dehumidification is therefore required. Energy savings from this technology can be attributed to the removal of excess moisture from air circulating in the business premise. A liquid desiccant solution simply absorbs excess moisture from air, making it easier for the A/C to cool the building energy efficiently.

Demand Controlled Ventilation

As the name suggests, the technology ensures that fans in the ventilation system only work when ventilation is needed. The technology uses carbon dioxide sensors fitted with economizers to turn the ventilation system on and off with the aim of maintaining appropriate air levels in the building. This technology basically prevents over-ventilation, which can lead to huge energy loses.

At Canoga Park Heating and Air Conditioning, we can assess your needs and propose the most suitable energy saving technologies.

Stop Mold Growth In Your Office's HVAC

Stop Mold Growth In Your Office's HVAC

Most of today’s businesses have an HVAC system which is harboring some level of mold growth. Mold cannot be avoided, but it is possible to keep its growth under control. The more mold, the more likely your employees will suffer from respiratory problems aggravated by the mold growth. Mold can be unnoticeable, but it could also be indicated by employees suffering from respiratory problems. This is especially probable if they already suffer from asthma, allergies or other respiratory illnesses. The best way to tackle this problem is to stop mold growth from growing to an excessive level.

How To Effectively Stop Mold Growth

The most effective way to control mold growth is to clean the HVAC system regularly. First turn the HVAC system off before you begin cleaning it. Clean the entire system with a disinfectant and apply a mold inhibitor. Your cleaning efforts should include the ductwork, filters and fan blades. Use a wet vacuum to clean up any standing water as mold needs water to grow. After cleaning the ductwork, filters and fan blades, you must allow them to dry thoroughly before turning the system back on.

It’s important to clean and or replace the HVAC filters regularly to ensure proper ventilation. Proper air flow is essential for keeping your HVAC system dry and less conducive for the growth of mold. As long as the system is cleaned regularly and kept as dry as possible, mold growth should be limited.

Regular Maintenance Is Important

To stop mold growth, you simply have to be aware of the fact that it is always growing somewhere in your space. The important thing is that it not be allowed to grow unchecked. Your company may already be hearing complaints from employees about their health. Uncontrolled mold growth could already be responsible for encouraging illnesses. This could be tested by evaluating whether or not the complaints are mostly coming from one particular area of your work premises. Hiring an HVAC professional to clean your system will help identify excessive mold growth in any specific area.

Our HVAC professionals will start looking for mold in the area where most of the complaining employees work. Then we can clean your whole system and keep it cleaned regularly to prevent a recurrence of the same health problems.  Click Here to read more about our Commercial HVAC Services.
