Benefits Of An HVAC-R System

AC tune-ups are designed to ensure your system operates at maximum efficiency and reliability. To that end, our AC tune-up services include the following and more:


  • Flushing condensate drain
  • Calibrating your thermostat
  • Inspecting the system for refrigerant leaks
  • Examining and tightening of all electrical components
  • Inspecting the blower belt and fan motor for signs of damage
  • Inspecting for rust, bulges, and other damages
  • Inspecting and changing the oil filter
  • Checking return and supply air vents for damage and blockages

Installing an HVAC-R system promotes better efficiency of the heating, ventilation, air conditioning, and refrigeration appliances of your home or business. Improving these systems reduces the amount of energy needed, which in turn reduces your carbon footprint.

What’s Included In An HVAC-R System?


HVAC-R systems supply heating, cooling, and ventilation for indoor environments. They are comprised of many different parts that work to keep the system running:


  • A filtration system that cleans outside air.
  • One or more fans to circulate the supply and return air.
  • Ductwork to bring the circulated air around the building.
  • A device that draws in outside air.
  • A heat exchange system that warms or cools the air.
  • A heating component to heat the air.
  • Compressors and condensers that transport refrigerant through the air conditioning and refrigeration systems.
  • Fans to circulate air through an air conditioning system.
  • Water chillers and boilers for central systems.
  • Controls.


Sky HVAC technicians install, maintain, and repair climate-control devices like air conditioners, furnaces, refrigerators, and freezer units.

Why Is Refrigerant Important?

Refrigerant is the compound tasked with absorbing heat from its environment to provide adequate cooling to another. Refrigerant is a compound that can be used in either a fluid or gaseous state. When combined with compressors or evaporators, refrigerants can provide refrigeration or air conditioning. Refrigeration systems maintain temperatures needed to keep goods chilled and fresh for longer periods.

HVAC-R Frequently Asked Questions

Is refrigeration part of the HVAC-R system?

Yes. HVAC-R stands for heating, ventilation, air conditioning, and refrigeration.


What is the difference between HVAC and refrigeration?

A major difference between refrigeration and HVAC is the origin of the supply of gases. Air conditioners have circulation systems that project cool air away from the units. Refrigeration units have circulation systems that retain coolant to a confined area. Both air conditioning and refrigeration units depend on converting liquid to gas in the cooling process; however, the way they do this is different for each system.


Which refrigerant is used in HVAC systems?

Most new systems use hydrofluorocarbons (HFCs) because they have greater cooling properties than HCFCs and are also much better for the environment.


What is an HVAC system?

HVAC stands for “heating, ventilation, and air conditioning.” HVAC systems include a central heating unit as well as a central cooling system. HVAC systems control temperature, humidity levels, and indoor air quality through ventilation.

As the summer heats up, you’ll naturally be using your air conditioner more and more. This is an effective way to beat the heat, but extensive use of your AC unit can cause wear and tear, or reveal existing problems. We at Sky HVAC want to help you and your family stay comfortable this summer, and to help you do that, our team has put together a list of signs to watch for in order to tell if you need air conditioner repair. Blows Warm Air - One clear sign that something is up with your air conditioner is warm air coming from your vents. If you put your hand by a vent and feel warm air, you probably need air conditioner repair. Makes Loud Noises - Another sign you should be wary of is loud or unusual noises coming from your AC unit. All air conditioners will make some noise as they run, but if you hear grinding, screeching, or scraping sounds from your unit, you should call our team at Sky HVAC to find out if you need air conditioner repair. Smells Bad - Your air conditioner is not supposed to stink. If you notice a bad smell coming from your unit when you turn it on, it’s likely that you need air conditioner repair. A musty smell usually indicates mold somewhere in your system, while a burned smell is likely the result of wire insulation burning out. If you notice any of these signs in your home or find something else unusual happening in your air conditioner, call our team at Sky HVAC. We’ll identify the problem and get your AC running smoothly as soon as possible.

Here at Sky HVAC, we specialize in all things air conditioning, and we want to help you stay cool this summer. Our team believes that the best way to help you take care of your air conditioning unit is to help you understand how it works. Knowing the principles behind your air conditioning unit will help you spot potential problems early and take care of them before they can become serious—or expensive. From our experts at Sky HVAC, here is a brief overview of how air conditioning works. Despite its association with cooling, the principle behind air conditioning is the transfer of heat. The typical air conditioning unit consists of an evaporator, a compressor, a condenser coil, and a fan. The evaporator is located inside the home, and contains a refrigerant that absorbs the heat energy from your home; as this happens, the refrigerant evaporates, hence the name. From there, the heat absorbed in the evaporator is transferred to the condenser coil, located in the exterior half of your air conditioning system. Also located outside with the condenser are the compressor and the fan. The compressor keeps refrigerant circulating throughout your system so that heat can be continually absorbed. Similarly, the fan keeps hot air moving out of your home. We hope that this article has been helpful to you. If you are experiencing problems with your air conditioning, or have further questions on how your unit operates, feel free to call our team at Sky HVAC.
