Efficiency: It’s All In the Installation

February 3_NIST Quality HVAC Report ImageA recent National Institute of Standards and Technology (NIST) report proves that HVAC equipment requires a quality installation (QI) in order to perform at its rated efficiency. The report, “Sensitivity Analysis of Installation Faults on Heat Pump Performance,” shows design and installation deficiencies contribute directly to a rise in energy consumption.

The report is based on a three-year study that focused on how the building, equipment and climate affect HVAC performance. The following installation faults were found to have the largest potential impact on efficiency:

  • Duct leakage
  • Low indoor airflow
  • Refrigerant undercharge or overcharge
  • Oversized equipment with undersized ductwork
  • If two or more simultaneous faults occur, the loss of efficiency and amount of energy consumption risk amplification

A QI requires high-efficiency products, correct design, proper installation and accurate field measurements. To help ensure these components are met, the ANSI/ACCA 5 QI Standard specifies what to measure, how to measure and the measurement tolerances necessary for unitary residential and commercial HVAC systems.

We recognized that a successful, sustainable installation not only requires a high-performing product but top-notch service as well, which is why we created the Diamond Dealer™ program more than 10 years ago. This elite group is the most extensive, highly-qualified contractor network in the industry today. Through demanding certification and continuous education, our Diamond Contractors™ ensure that our energy-efficient products perform at their industry-leading efficiencies.

White Paper: VRF Zoning Systems Get Historical

Historic building renovations present unique challenges for HVAC contractors. Many historic structures lack the space for ductwork, and their electrical systems probably weren’t designed to handle modern central cooling and heating requirements. Contractors are expected to modernize the building while preserving its architectural and aesthetic integrity, which is no easy feat.

We’ve published a new white paper detailing why VRF zoning systems are a particularly smart HVAC choice for meeting the unique challenges of a historic building renovation. This white paper can be a great resource for contractors, engineers and other building professionals who are hoping to learn more about VRF zoning technology for this potentially challenging application. The paper also outlines how VRF zoning systems can help historic buildings earn a substantial number of green building certification points, which is increasingly important in today’s industry.

Here are some highlights of why VRF zoning systems work well for historic building renovations:

  • Architectural Preservation: Systems can be installed with minimal impact on the building’s architecture and help projects comply with requirements of the U.S. National Park Service, which call for preserving distinctive materials and construction techniques. Indoor units can be mounted just about anywhere, so high ceilings and period finishes can be preserved, which is very important to the aesthetics of historic buildings. Check out the Turner Construction case study for more information.
  • Energy Efficiency: Some VRF zoning systems can heat and cool simultaneously, and units can be dedicated for small loads. Plus the 100 percent INVERTER-driven compressors and integrated energy recovery capabilities help with cutting down energy consumption. Check out the Miami University case study for more information.
  • Flexible Installation: Condensing units are compact and light enough to be installed on a roof or small mechanical room, without comprising the structure. And small refrigerant lines are easy to install and can be camouflaged on the outside of the building. Check out the Strawberry Mansion case study for more information.

Four Tips to Convince Your Customers to Go Ductless This Summer

Selling Split Ductless

As temperatures rise, so do calls for HVAC repairs and replacements. Ductless systems are a great solution for the summer heat. They can be installed quickly, and they work well as a whole-home solution or as a supplement to an existing system. Although ductless systems are one of the fastest-growing segments in the U.S. HVAC industry, they’re still relatively new to the American market, and consumers may not know a lot about them.

Let’s educate them. Here are four benefits of the systems that will help you convince customers to go ductless this summer:

Energy Efficiency: Ductless systems are up to 40 percent more efficient than other types of HVAC systems. No ducts mean no duct loss and increased energy savings.

Allergies: The systems’ advanced allergen-filtration technology and washable filters eliminate contaminants from the air. Also, the potential for accumulation of mold spores and dust in ducts is decreased or eliminated, further improving air quality.

No More Hot and Cold Spots: The zoning capabilities of the ductless systems give homeowners complete and individual control over their comfort in each room.

Easy Installation: For both new construction and retrofits, these systems are easy to install. They require little to no ductwork, minimizing demolition in retrofits. And since the small footprint takes up less space in the home, homeowners have more usable space.

To learn more about how to sell ductless technology as the solution to the most common comfort complaints, visit We’re happy to help give you a leg up on the competition during your busiest time of year.
