Keeping Warm and Cool: Commercial HVAC Systems

When working in an office, you want to be comfortable. One of the key components of comfort is being either warm during cold days or cool during hot ones. This is where having a commercial HVAC system installed in your building is useful.

The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has strict standards for the HVAC systems that ventilate buildings. It specifies the comfort zone of 68 degrees F to 75 degrees F for the winter season and 73 degrees F to 79 degrees F during summer. The humidity levels of the air should be at 50%, and the air should be moving at 30 feet per minute or slower. Continue reading

Tips in Choosing an HVAC Contractor: Pre-Search

There are numerous HVAC contractors with glowing ads about their service in the market, and it can get tough just trying to pick out the right one for the job. Here are simple tips to narrow down your list.

Don’t assume that all contractors are pretty much the same

Why? Because they simply aren’t. Variations do exist in heating and air contractor competence and ethics. While many of them are reputable in their own right, some simply may not have the business systems in place to properly serve a consumer’s specific needs or demands. Before choosing one out of many, find out first what you need and the job that needs immediate attention, then narrow down your choices to the contractors that specialize on the problem at hand.

The Benefits of HVAC Maintenance for Businesses

Almost every employee will tell their employers that they cannot─ and will not─ produce properly if they are not provided at least the most basic of comforts. These include a good chair, periods of rest, and good coffee among other things. Moreover, they cannot work properly if the air is too hot or humid, and that’s why a proper HVAC unit for the office will be important.

The HVAC will provide the ideal temperatures for employees to be able to work inside the building regardless of the weather outside. Machines are bound to break down, however, and so business owners will need to take regular HVAC maintenance seriously. Here’s a look at what employers can get out of doing so:

Financial Savings

A business owner who wants to make a profit will definitely want to have his HVAC systems regularly checked. A regularly maintained system means that there will be no immediate expenses to be made in replacing the unit. It will also make the HVAC system more efficient, which will surely bring down the company’s energy expenditures.

Peace of Mind

No one wants to constantly be thinking about when the HVAC unit will finally break. If the HVAC system uses a gas furnace, regular maintenance will ensure the safety of the unit since carbon monoxide will have exits to be directed through to. This protects the entire building and the people using it.

HVAC Retrofitting Helps Save Buildings Money

There’s no denying that heating and cooling a home is expensive. Now, imagine what it costs to keep a comfortable temperature inside government buildings, malls, high rises, and other commercial structures.

Indeed, all commercial property owners know that while HVAC systems are vital to maintaining ideal indoor temperature, they are also big consumers of electricity and, by extension, money. However, the Pacific Northwest National Laboratory, a government research laboratory overseen by the Department of Energy, notes that large buildings can save 25%-35% on their heating and cooling costs by retrofitting their current HVAC systems.

Variable Frequency Drives in Single Zone Rooftop HVAC Units as Installed by Commercial HVAC Contractors

As Variable Frequency Drives (VFDs) become more affordable, there are more applications where their energy savings make them economically viable. One relatively new use is the control of evaporator blowers in single zone rooftop units. The fan energy savings are obvious, especially if you are familiar with fan energy consumption (fan laws). A fan running at one-half speed uses one-eighth of the energy of a fan running at full speed. In addition, the lower air flow across the evaporator coil results in the air being cooled to a lower temperature, which in turn removes more moisture, lowering the humidity in the space. If you have commercial HVAC specialists add VFDs to your equipment, you can obtain additional savings by raising the cooling setpoint since the occupants may be just as comfortable at a slightly higher temperature with the lower humidity.

How to Find a Good HVAC Contractor

The eventual breakdown of a heater is an undeniable reality. Despite hard-nosed maintenance efforts, constant usage and unpredictable weather, like the cold wave North America has experienced over the past weeks, can wear any machine down.

Fortunately, there are HVAC repair services that can solve your heating problems and provide immediate warmth to those that need it immediately. However, there are a lot of services that promise high-quality HVAC work, so finding the right service can become a tedious search for anyone to do.

Dazed homeowners shouldn’t worry, as there are qualities that you can look for in a HVAC contractor that can help you find the best.

One way of finding out an HVAC contractor’s capabilities is through its other customers. If these customers are satisfied with the work the contractor has done, then you can be assured of the same quality of service.

Another thing to consider is the importance of diagnostics for the contractor. A good contractor will stress the importance of diagnostic testing, and will quote a price from the tests done by the contractor.

Finally, a trusted contractor will show customers how to take care of their HVAC systems. Good heating contractors do not simply repair heating systems; they help the homeowner maintain it for a long period of time.

Qualities of Commercial HVAC Contractors

There is no shortage of HVAC contractors, be it for residential or commercial purposes. However, it can be difficult to find contractors who will take into account both your needs and budget. You may have to spend a great deal of time and effort in searching for reputable HVAC companies that can provide you with exceptional work at a fair price. Aim for the following qualities when searching for HVAC contractors specializing in commercial systems to be assured of remarkable service:

Desire to Help

It may seem impossible to find contractors focusing on high-quality service rather than sales. However, there are those who exist for customer satisfaction through superior service and honest pricing. Do your research well, provide specific demands, and assess how you are treated.

Expert Guidance and Reasonable Options

Opt for commercial HVAC contractors willing to go the extra mile to fulfill your needs. The contractor should not insist on a full unit replacement without determining the exact causes of issues first. There should be a clear estimate and explanation of the problems and possible solutions instead of merely jumping into conclusions.

Look into the credentials and customer references of your prospective service provider. Ask for referrals from people you trust, particularly from those who have had similar HVAC concerns. Check licenses and bonds or insurance details including their brand affiliates.
