Frank Gay Commercial has been in the HVAC-R industry for years but what exactly is HVAC-R? Read our FAQs here!

What is HVAC-R?

HVAC-R stands for heating, ventilation, air conditioning, and refrigeration. While HVAC and refrigeration are two different systems, they are grouped together since both regulate temperature and control humidity. Both systems also use similar parts such as condensers, evaporators, and compressors to work with changing temperatures.

What are some different types of HVAC-R equipment?

  • Single Split- Heating and cooling system with an indoor and outdoor unit. Each part of this system is not centralized and can function if another part stops working.
  • Multi-Split- Similar to a single split system but it includes heat pumps which saves money on energy. Multi split systems also have sensors to sense temperature changes.
  • VRF- VRF systems are better for larger spaces as some can heat and cool different rooms at the same time. They are easy to install and reliable.
  • Walk-In Cooler/ Freezer- Both units store and keep food cool but walk-in freezers operate below 0 degrees Celsius and have heated doors to keep the unit from freezing shut.

How are commercial and residential systems different?

Commercial units tend to be larger in size. In terms of HVAC, commercial units are placed in different locations and can be placed on top of the property. Commercial refrigerators usually do not have many shelves or cabinets like home refrigerators do.

Commercial units also have more complex functions and demands placed on them. Due to these differences, it is best to call a licensed technician to maintenance your system.

When should you service HVAC-R equipment?

Frank Gay Commercial recommends that your unit should undergo preventative maintenance at least twice a year. The age and size of your unit may influence how often service should be done. Here at Frank Gay Commercial, we have an operation checklist to ensure the protection of your system. If you are unsure about how often your unit should be serviced, give us a call!

Customer Reviews
Sienna Wheeler

I used Frank Gay for electrical services. I wanted to have my outdated light fixture upgraded to something more modern and classy. My technician was Mario and he was incredible! Very fast and efficient service. He was also very friendly and knowledgeable. I highly recommend this company!

Justin Collins

Michael Gilbert was very knowledgeable and helpful with the repair process. He also made recommendations for repairs that we didn’t know were issues until he showed us the problems. He provided us pricing for the repairs itemized and combined. He is an all around good guy to talk to while he was getting the job done. In the end everything came out just right. Thanks Michael take care!
