When final sales numbers are announced in January, the global HVAC equipment market should be reporting another year of above-average growth. According to a report from Chisult Insight Co., Ltd, the fundamentals now in place for the United States are the best they’ve seen in over 10 years. The research report stated that the residential HVAC market experienced significant potential growth based on the beginnings of a recovering new housing market, overall higher employment, lower gas prices, and higher consumer confidence combining with a better price/mix and lower raw materials costs. The good news also extended to the commercial market with a steady recovery in building construction in 2015.
The Chisult report indicates that underlying trends are now firmly above the electrical equipment and multi industry (EE/MI) sector average and should be sustainable. The potential upside comes from continued release of pent-up demand and better weather compared to a cool summer in 2014. While the buying impact from 13 SEER should reduce reported Air Conditioning, Heating, and Refrigeration Institute (AHRI) shipment volume numbers by 8 percent in 2015, 14 SEER is positive which benefits margins and sales. The Chisult report also said the U.S. commercial HVAC market remains a more straightforward call, where about 5 percent growth in 2015/16 is based on an ongoing nonresidential construction recovery (6-7 percent growth) and a stable 4 percent replacement market. Ductless continues to be the new “next big thing” for the industry. The ductless systems market could come to represent 15 percent of the industry for both residential (approximately 10 percent) and commercial (approximately 5 percent). With energy efficiency driving technology and product R&D, manufacturers were able to realize price increases in 2014, with most companies announcing low- to mid-single-digit price increases for 2015.
The latest stats from the Air Conditioning Heating Refrigeration Institute’s (AHRI) October 2015 report, year-to-date combined shipments of central air conditioners and air-source heat pumps increased 1.1 percent, to 6,097,714 units, up from 6,033,336 units shipped in October 2014. Year-to-date shipments of central air conditioners increased 2.2 percent to 4,082,457 units, up from 3,993,768 units shipped during the same period in 2014. The year-to-date total for heat pump shipments decreased 1.2 percent to 2,015,257 units, down from 2,039,568 units shipped during the same period in 2014.
The HVAC industry was on the cutting-edge of technological advancements in 2015. Many of the new technologies were focused on making it easier for a home/building owner to manage their energy use with smart thermostats, smart ventilation systems, smart device enabled applications and the integration of the Internet of Things (IoT) in the design and construction of homes and commercial buildings.
The HVAC contracting business also benefitedyou from technology designed to help contractors provide better customer service with IoT platforms that utilize smart devices and allow sales and service representatives to automate their sales and service processes, making it more convenient and user friendly for customers.
Focus on Energy Efficiency
As more states adopted new energy efficient building codes in 2015, HVAC contractors had to become more familiar with how to “right fit” an HVAC system for a building that is built to high efficiency or Net Zero Energy standards. In 2015 the Air Conditioning Contractors of America (ACCA) developed “HVAC System Design for Energy Efficient Homes,” a manual for HVAC contractors to follow as a new industry standard. This standard will provide procedures to design/select HVAC systems and equipment for low-load homes that will achieve satisfactory indoor conditions with lower equipment capacity; i.e., resolving ventilation and moisture requirements/issues with low air volume systems while addressing occupant comfort, health, and safety. These procedures will become more important as lower capacity equipment appears in the marketplace in 2016 and beyond.
In addition, energy efficiency and sustainability have gone beyond being buzzwords in the commercial HVAC sector as well. In 2015, commercial builders, owners and managers put saving energy, money and natural resources at the top of their lists. Since heating, ventilation, and air conditioning (HVAC) equipment consumes a substantial portion of energy in commercial buildings—roughly 40% to 60% of total building energy consumption depending on climate and other factors, this trend will become even more important in the design and building of commercial structures.
High Efficiency HVAC systems – HVAC manufacturers embraced the new regulations introduced in January 2015 and began to deliver high Seasonal Energy Efficiency Ratings (SEER) HVAC units to their distributors in Spring 2015. With the focus on energy efficiency and using enhanced technology and IoT features, many manufacturers designed and produced HVAC units with SEER ratings way beyond the required 14 SEER. CE carries a full line-up of HVAC units from that offer 13 to 23 SEER ratings and feature Wifi controls, wireless thermostats and variable speed compressors. To find out more about all the high efficiency units available, visit: http://www.carrierenterprise.com/residential-equipment/air-conditioners
Ductless systems – One of the hottest new products at the 2015 AHR Expo was ductless HVAC systems. With the ductless market predicted to grow to more than $9 billion by 2020, more and more manufacturers and contractors are embracing the ductless system as a viable alternative for providing comfort solutions to residential and business customers. Ductless units introduced in 2015 are much more efficient and attractive and there are a myriad of options for system configurations to meet your customers needs. Systems have been designed to provide high efficiency ratings up to 30.5 SEER (Carrier’s Infinity Series), 80 percent heating capacity at minus 20° F, and smart controls. Systems can be easily installed on the floor, a cassette system in the ceiling or in the wall depending on esthetic needs and space restrictions. And units can be controlled remotely or with a digital thermostat mounted on the wall.
Ductless systems have become very popular for customers who have older homes or buildings that were not built with space for a ductwork system. Many historical homes or commercial buildings that don’t have adequate attic space for a central air conditioning system can benefit from the installation of a ductless system, which can increase the comfort level and long-term value of the building. CE carries a wide variety of ductless systems to meet every need.

The winter season is an ideal time to focus on your facility’s chiller maintenance, which is one of the largest operational expenses in any HVAC system. The task is so important that the US DOE recommends a chiller’s maintenance takes place once a year at minimum. There are several steps maintenance personnel can take to keep top-notch performance of chillers. Keeping tubes clean will ensure efficiency and prevent pressure loss due to corrosion. Leaks in the system can cost facilities money and threaten the health of occupants by releasing hazardous refrigerants. Chiller leaks should be serviced immediately and units monitored for recurrences.

For the last several years, energy efficiency has been on everyone’s radar as the need to conserve energy and money has become more important for both businesses and residents. Since a home’s heating and air conditioning system is the biggest user of energy (more than half, according to the U.S. Department of Energy), the HVAC industry has been on the cutting-edge of developing new technology and equipment to meet the demands of both the government and the end user.
New 2015 Energy Efficiency Standards
In January 2015, new residential central air conditioning systems and heat pumps had to meet tougher standards, depending on where the home is located.
Homeowners in the North will adhere to the old minimum of 13 SEER (Seasonal Energy Efficiency Ratio). Homeowners in the warmer Southern states saw the minimum rating increased from 13 SEER to 14 SEER. Additionally, in five Southwest states (Arizona, California, Hawaii, Nevada and New Mexico), central air conditioning will require an EER (Energy Efficiency Ratio) of 11.7 or 12.2, depending on the size of the unit, along with a 14 SEER rating.
The most significant change regarding the new regulations involves all split-system heat pumps. All regions will move from 13 SEER and 7.7 HSPF, Heating Seasonal Performance Factor, to the new national heat pump efficiency minimum of 14 SEER and 8.2 HSPF.
The majority of U.S. manufacturers already offer 14 SEER heat pump systems, and many manufacturers may update current 14 SEER designs to meet product demands for 2015 inventory stocking. The remaining inventory of 13 SEER equipment can be installed until the set deadline: July 1, 2016.
“Whole” Building Science Has Become the Norm
As more states adopt new energy efficient building codes, HVAC contractors will need to become more familiar with how to “right fit” an HVAC system for a building that has been built to high efficiency or Net Zero Energy standards. The Air Conditioning Contractors of America have recently developed “HVAC System Design for Energy Efficient Homes,” a manual for HVAC contractors to follow as a new industry standard.
This standard will provide procedures to design/select HVAC systems and equipment for low-load homes that will achieve satisfactory indoor conditions with lower equipment capacity; i.e., resolving ventilation and moisture requirements/issues with low air volume systems while addressing occupant comfort, health, and safety. These procedures will apply as lower capacity equipment appears in the marketplace.
Homes are getting smarter, with various devices talking to each other and the homeowners.
Household appliances, the HVAC system, lighting, window blinds and thermostats, among other devices, can be controlled through a smart phone and provide updates on status.
Smart thermostats are a big part of the Internet of Things home revolution. As more homeowners and building professionals come to understand the value of a smart thermostat, the market is expected to soar in the U.S. and Europe.
A smart thermostat is more than a programmable thermostat. With a traditional thermostat, one can turn the heating or cooling up or down, and with programmable versions, one can set the temperature to change depending on the time of day.
What makes smart thermostats so unique – smart– is that they learn and adjust the temperature based on the owners’ habits and the characteristics of the house. Not only will the devices come to know when the temperature should be raised or decreased, but they also learn how long the house takes to heat up or cool down. This means they can begin to adjust the temperature in just the right amount of time so homeowners can feel the change when they should – not 15 minutes later.
Ductless HVAC Systems
Once seen as a solution for home additions and bonus rooms, now ductless systems, also known as mini split, are available to provide whole-home solutions with outdoor systems that can handle up to 8 indoor units. An array of indoor air handler options, such as ceiling cassettes and wall-mounted units, give homeowners and contractors the flexibility to ensure that convenience and aesthetics are achieved. New technology addresses some of the shortcomings of heat pumps, such as a loss of heating capacity in sub-freezing weather. New units on the market offer high levels of heating capacity in temperatures as low as 5 below zero Fahrenheit. Mini splits will be a more popular option in northern climates with less need for expensive back up heating.
Ductless systems are being utilized as the primary source of heating and cooling in both residential and commercial applications. Some of the many benefits of mini split systems are:
- Individual zones; heat and cool specific spaces when desired.
- Cheaper to install and maintain.
- Higher SEER ratings (up to 30.5 SEER with Carrier’s Infinity Series)
- Flexible installation options, including wall, ceiling and floor mounted indoor unit styles.
- Minimal energy loss; air does not travel through ductwork.
- Can also be used for garages and extensions where there is no ductwork
- Perfect for older buildings that cannot accommodate ductwork
- Quiet operation.
- Heating capabilities down to a temperature of -15° F.
Variable speed compressor technology brings to the HVAC industry whole new levels of efficiency, comfort, reliability and versatility. This technology is highly efficient and will reduce HVAC energy costs, while improving system comfort and reliability for homeowners. In order to enable the early adoption of variable speed compressor technology into the U.S. HVAC market, U.S. OEMs began introducing new, ducted systems with variable speed compressors as early as 2006 and more have followed since. Within the next few years, it is expected that all of the major OEMs will be offering high efficiency ducted variable speed systems in the U.S.
Variable speed systems work by connecting a motor control drive to the compressor and then connecting the line input power from the utility to the drive. The drive uses frequency modulation to adjust power output of the compressor motor, enabling it to speed up or slow down according to the heating or cooling load in the home. This ability to modulate compressor capacity enables many of the advantages of variable speed technology, including improved efficiency and comfort.
The ability to adjust power output to the compressor, rather than the merely on-off functionality provided by traditional systems, allows homeowners to achieve significant cost savings over the course of a year. In some cases these savings amount to 40% of the overall annual energy costs.

When customers are purchasing a new HVAC system they may be considering a ductless option, but they might want to know the benefits and the disadvantages of going ductless.
They may simply ask you, “What are the advantages of a ductless HVAC system?” and “Are there any disadvantages of installing one?”
Below features a few tips on how to discuss the “Pros and Cons” of installing a ductless HVAC system with customers:
- “You Save Money Over Time”
Money plays a major role when consumers are contemplating an important purchase. You can begin by explaining that they will save money over time by deciding to install a ductless HVAC system. You can point out how ductless systems have the ability to run on much less power than ordinary systems because they are smaller and deliver air directly into a room. By diving into more detail, you can explain that because they are ductless they also avoid energy losses that may come with ductwork of central forced air systems. It may also help to use some statistics such as, “These losses can be responsible for over 30% of energy consumption.” Overall you want your customer to understand that installing a ductless system essentially cuts costs and saves money over time.
- “Easy Installation”
If your customer is looking for a quick and easy installation process, you can explain this process and compare it to that of traditional systems. Note that traditional systems take several days and even weeks to install, while you can have the customer’s ductless HVAC system up and running in just one day. If you want to get into specifics, you can explain that the units usually run on small pipes that only require a three-inch hole through a wall, which avoids any rebuilding around ductwork.
- “You Breathe Easy”
Another benefit you can call attention to is the filtration that ductless HVAC systems have. Let the customer know that the filtration system decreases the amount of dust, allergens, pollen and bacteria in the air. After you explain this, you can mention how most ordinary HVAC systems require professional cleaning regularly and can still leave behind dust and allergens. Make sure the customer understands that ductless options enhance the air quality, which allows easy breathing.
- “Initial Costs May be Higher”
Although you may have already explained that your customer would save money over time by installing a ductless HVAC system, be transparent and clarify why the up front cost of purchase and installation is higher. You can explain the details of how the system’s efficiency and technology is more expensive to buy and install, but then remind the customer that the overall cost is lower when the system is operating.
- “Placement is Crucial”
Express the importance of placement when installing a ductless HVAC system and validate your credibility. Revert back to when you mentioned the efficiency of a ductless HVAC, and explain how improper placement will cause inefficient operation and wastes energy. You can end your point by making sure the customer understands improper placement can increase utility costs.
If your customer has indicated that style is essential, the indoor portion of the ductless HVAC systems may not satisfy his or her inner interior designer. You can try to identify your customer’s taste and make sure that you present certain options.

No matter what climate region you may be in, ductless HVAC systems are a great way to provide your customers with efficient heating and cooling solutions that will make their homes and businesses more comfortable and save them money on their energy bills.
Although ductless systems have been around for many years, they have recently seen a resurgence in popularity for a variety of reasons. The new units are much more efficient and attractive, and there are a plethora of options for system configurations to meet your customers’ needs. Systems have been designed to provide high efficiency ratings up to 30.5 SEER (Carrier’s Infinity Series), 80 percent heating capacity at minus 20° F, and smart controls. Systems can be easily installed on the floor, in a cassette system, in the wall/ceiling, or on the wall, depending on aesthetic needs and space restrictions. Units can be controlled with a remote control or with a digital thermostat mounted on the wall.
Ductless systems have become very popular for customers who have older homes or buildings that were not built with space for a ductwork system. Many historic homes or commercial buildings that don’t have adequate attic space for a central air conditioning system can benefit from the installation of a ductless system, which can increase the comfort level and long-term value of the building.
Here are some reasons you should consider for adding ductless HVAC systems to your company’s portfolio of offerings:
- They’re easy to install. These systems can be installed in much less time than it takes to put in central air conditioning. A two-person crew would need at least a week to install the ductwork and other components of a central air conditioning system. A ductless mini-split system could be installed from start to finish in a day. This translates to less labor for you and less inconvenience for your customer.
- They don’t take up much space. Their compact size makes ductless AC units perfect for cooling small living spaces, such as apartments and dorm rooms. They’re also great for cooling individual rooms in larger homes, particularly basements, garages and attics, which are usually not ventilated well. Also, ductless air conditioners are easy to store because of their small size, which means they take up less space in your warehouse and in your company trucks.
- They’re easy to maintain. Ductless systems have fewer mechanical components, use much less refrigerant and since there is no loss of airflow due to issues with ductwork, the systems tend to be easier to maintain.
- They’re energy efficient. Ductless air conditioners use much less energy than traditional air conditioners, which can save your customer money on their energy bill. In addition, if you install multiple units, the customer can control the individual room temperatures in the house, which is more energy efficient than using a central air conditioning system to cool the whole house.
- They’re quiet. Traditional air conditioners can make a lot of noise, but ductless systems are quiet. The noise they make is usually no more than a quiet hum. It amounts to background noise that is easily drowned out by conversation, music and television.
- They’re green. Ductless systems meet LEED standards and can earn points for a building seeking LEED certification.
