Your heating and air conditioning system is one of the most expensive and complex parts of your home. Keeping it running smoothly and repairing it when there are problems is important. Finding the right HVAC contractor is one of the best ways to ensure that your HVAC system operates at peak efficiency for the longest time possible.  An experienced and certified technician is an invaluable resource, and the person you’ll count on to keep you and your family comfortable in your home year round.

Qualifications are a key factor when choosing an HVAC contractor. They should have more than the bare minimum of  expertise.  Your contractor should be fully licensed and have experience.  He or she should be a member of industry organizations that set standards for licensing and best practices.

Additional third-party certifications are also available that HVAC technicians can earn.   Being certified by NATE is one of most prestigious in the industry, and the only one accepted by the entire HVAC industry. At Ohio Heating and Air Conditioning, we’re proud of the fact that we only employ NATE certified technicians. But, what does this designation mean for you as the homeowner?   NATE-3-1

What does NATE Certified mean?

North American Technicians Excellence, Inc. (NATE) develops and promotes excellence in the installation and service of heating, ventilation, air-conditioning, and refrigeration (HVAC/R) equipment by recognizing high-quality industry technicians through voluntary testing and certification. NATE is supported by a broad spectrum of industry representatives including contractors, distributors, educators, manufacturers, technicians and utilities.

What does employing NATE certified technicians mean to you?

NATE certified technicians are recognized as meeting the highest industry standards for knowledgeable installation and services of HVAC equipment and systems. This level of expertise means they are more likely to install and service systems right the first time. As a homeowner, this translates into better customer service, fewer callbacks and better word of mouth.

By hiring NATE-certified technicians, customers know they are getting employees who know what they are doing and who are serious about customer service.

Manufacturers and distributors of HVAC equipment endorse NATE certification because it encourages proper installation and service of equipment, which ultimately means fewer service calls and warranty returns later on.  

Other advantages for homeowners and the HVAC industry include:

  • Certified techs stay in the industry longer and are more productive than non-certified techs.
  • NATE provides a uniform standard of knowledge that trainers can use to prepare the future HVAC workforce.
  • Properly trained and tested technicians can assure the correct installation and servicing of HVAC equipment, which saves homeowners on their energy bills over time.

NATE certified technicians will size and install your system so that it operates at peak efficiency, saving you money and energy.  This is significant because, according to www.energystar.gov, improper installation of your HVAC equipment can reduce its efficiency by up to 30 percent! No one wants higher utility bills and a shorter life for their equipment.

What Type of Chiller is Right for Your Application?

Posted by Ohio Heating

Feb 23, 2021 1:19:15 PM

Chiller units are refrigerant systems that help cool commercial spaces, machinery,air cooled chillers_s industrial operations, and industrial chemicals. Two of their biggest advantages are that they are energy and cost-efficient.

Chillers provide a continuous flow of coolant to the cold side of a process water system at the desired temperature of 50°F. The refrigerant is then pumped through the process pulling the heat out of one area of a facility.

Chillers are categorized by types. The two main types are vapor compression and vapor absorption chillers.

Vapor compression chillers use an electrically driven mechanical compressor to force a refrigerant around the system while vapor absorption chillers use heat to move the refrigerant around the system.

Vapor compression chillers are the most common and fall into two subcategories: air-cooled chillers and water-cooled chillers.

Water-cooled chillers tend to be more efficient than air-cooled chillers. When water evaporation is used to dissipate heat, less energy is used versus blowing air across a hot surface. Water has a higher heat capacity than air so it is much easier to remove the heat. Water chillers when properly maintained will tend to last a lot longer than air-cooled chillers.

Air-cooled chillers cost less to install as they have less equipment and require less space. Rooftop installation negates the need for a mechanical room and frees up more space within the building. Typically, they do not have as long a service life as water-cooled chillers due to exposure to the outside elements.

Chillers are further categorized by the type of compressor used: centrifugal, screw, reciprocating, and scroll chillers.

A centrifugal chiller uses rotating impellers to compress the refrigerant and move it around the chiller. The majority of centrifugal chillers are water chillers. These are used for medium to large cooling loads and offer high cooling capacity in a compact design.

Centrifugal compressors have better full-load efficiency, and screw compressors can achieve comparable part-load efficiencies.

Screw chillers are also used in both water and air chillers and are ideal for small to medium cooling loads. They use two interlocking rotating helical rotors to compress the refrigerant and capacity is controlled via speed control or slider.

Screw compressors work by using two interlocking rotating helical rotors to compress the refrigerant and they are preferred for part-load applications. These are stable down to about 10% capacity, where centrifugal compressors begin to surge at around 20% to 40% capacity.

Reciprocating compressors have two types: air-cooled or water-cooled. They use cylinders with pistons acting as pumps to increase coolant pressure, much like a car engine. Reciprocating chillers are smaller than centrifugal chillers and can cope with the specific demands from load on the system.

Scroll compressors are most often used for small buildings with cooling loads under 200 tons or 700 kW. A scroll compressor works by using two interleaving scrolls (one scroll within the other) to compress the refrigerant. Usually self-contained, scroll compressors are used in both air and water coolers. They are known for quiet operation and their dependability.

Whether it's for rooftop chillers, light commercial or industrial applications, Ohio Heating & Refrigeration has solutions for air conditioning and heating that are designed to meet a wide range of building and application regulations. Call us at 614-863-6666 to learn more.

Do You Have a Leak in Your Commercial Refrigeration Unit?

Posted by Ohio Heating

Jul 5, 2017 11:00:00 AM

Do you think you may have a  Freon leak in your refrigeration equipment?

Commercial and industrial refrigeration systems can leak up to 30% of the charge during a year. Leak rates can be dramatically reduced with adherence to best practices in service, maintenance leak testing and repair.chiller-955192-edited

Detecting Freon leaks is very important.  These leaks can cause serious health issues if they are not repaired.

Freon poisoning happens when someone is exposed to the chemicals used to cool appliances such as refrigerators and air conditioners. Freon is a tasteless, mostly odorless gas. When it is deeply inhaled, it may cut off vital oxygen to your lungs and cells.

Limited exposure from a spill on your skin or breathing near an open container is only mildly harmful. However, care should be taken to avoid contact with these types of chemicals. According to the California Office of Environmental Health Hazard Assessment (OEHHA), even small amounts can cause symptoms.

Symptoms of Freon poisoning:

  • dizziness
  • headaches
  • irritation to the eyes, nose, and throat
  • heart palpitations

Inhaling these fumes on purpose to “get high” poses a dangerous health risk. Regularly inhaling high concentrations of Freon can cause breathing problems, fluid buildup in the lungs, organ damage, and sudden death (OEHHA, 2003).

if you think you have noticed commercial refrigeration leaks, call us. Our trained technicians can help you detect the source and repair your cooling equipment.
