VRF systems vary from their counterparts in a few key ways. Where conventional HVAC systems heat or cool the air prior to distributing it throughout your ductwork and home, VRF systems send air directly to the air handler inside prior to conditioning. Once the air reaches the air handler it is then heated or cooled and dispersed directly into that zone. Because of the unique zoning technology, VRF systems have the ability to heat one zone while simultaneously cooling another.

Maintenance, Service & Inspections  

Equipment maintenance is the most important part of maximizing the life of your unit. Our trained staff focuses on taking care of your HVAC equipment during the off-season months to give you peace of mind when it counts the most.

Heating Furnaces & Systems  

Wolff’s service staff is trained and certified to work on all gas heating systems in order to ensure that your equipment continues to run as efficiently and safely as possible.

Tankless Water Heaters  

While a traditional tank water heater heats water continuously, tankless water heaters heat only as much water as needed, when it is needed. By heating water on demand, tankless units can reduce energy use by 24 to 34 percent compared to traditional water heater tanks.

Filters Accessories & Parts 

Wolff sells a wide array of filters and custom accessories to the general public. Call or stop by our convenient Tempe location.
