Choosing the Right HVAC System for an Energy-Efficient Home


energy efficientHVAC systems don’t last forever, and when it’s time to install a new one, the decision can be difficult. With the introduction of new technology, there are many options for a new purchase or even technologies that can enhance the efficiency of your current system. Since your HVAC system performs a vital function in your Mobile, Alabama, home, and is a major investment. It is important to make an informed decision when making any type of upgrade. The following are a few factors to keep in mind when choosing a new HVAC system for an energy-efficient home.


Not all HVAC systems heat or cool a home the same way. If you live in a smaller home, you don’t need an HVAC system with a high heating or cooling capacity because you will end up wasting energy. On the other hand, if you live in a large home or are installing a system into a large business, a small HVAC system may not have the capacity to keep the building at a comfortable temperature. Before deciding on a system, research the heating and cooling capacities. For the most effective solution, consult your HVAC technician.


When installing a new HVAC system, consider the current technology that can turn your system into a highly-efficient machine. Smart thermostats keep the temperature under precise control, allowing you to save as much as possible on your utility bill. Whole-home air purifiers provide additional filtration power to significantly improve your indoor air quality. These and other innovations will save you money while keeping you comfortable.

Advanced Options

There are many options for managing the temperature and indoor air quality in your home including ultra-efficient heat pumps and radiant heating. Depending on the size and location of your home, these options could save you more money than a standard HVAC system would.

Looking for HVAC Systems? These Carrier Products Fit the Bill

Installing a new or upgraded HVAC system in your home is a decision that requires careful thought and planning. New air conditioners, furnaces, heat pumps, and other equipment can be a significant financial investment. It is necessary to install a system that works best for your specific needs and with the individual characteristics of your home. You also want to balance energy efficiency with cost and make sure you get a system that will provide reliable function over a reasonable service lifetime. When you are seeking the best HVAC systems, Carrier products stand out for efficiency, dependability, and performance relative to cost.

As some of the industry’s best HVAC systems, Carrier products can keep your home comfortable in any season. These systems are backed by a manufacturer dedicated to customer service and satisfaction for more than 100 years. You will find that Carrier not only provides top-quality HVAC equipment, but that the company also works to be a good neighbor by supporting the communities nationwide.

Carrier Quality and Choice

For consumers who want the best HVAC systems, Carrier products reflect the care and concern of a proven market leader. New Carrier systems are also engineered to use newer, more environmentally friendly refrigerants. The company offers durable and highly-efficient choices that are designed to fit many budgets and home comfort requirements. Carrier products marketed in communities throughout the United States include central air conditioning units, split-system air conditioners, furnaces, heat pumps and package units.

HVAC System Efficiency

When purchasing a new air conditioner, furnace, or heat pump, system efficiency is usually a top priority. These systems have a seasonal efficiency ratio (SEER) as high as 21. SEER is a measure of system efficiency. The higher the SEER, the more efficient the system.

Because of their performance standards, high-efficiency units can produce outstanding levels of heating or cooling at a much lower cost. Purchase and installation costs of high-efficiency systems are generally more than traditional and lower-rated systems. However, such systems will save you money on repairs and energy consumption because of better performance. This, therefore, makes the units a worthwhile investment. You will find a full line of highly-rated, high-efficiency HVAC systems among Carrier’s product selection including:

  • Ductless systems: Ductless or mini split air conditioners consist of two main units: an outdoor unit that contains the condenser and compressor connected via a narrow conduit to an indoor unit that handles the distribution of conditioned air, and control of indoor temperatures. Carrier’s split system air conditioners are available in multiple levels of efficiency, ranging from SEER 13 to SEER 21. More advanced models, such as those in the Infinity Series, include features and components that boost system efficiency even further, including variable-speed compressors.
  • Packaged units: Packaged air conditioning systems include all functional components in a single cabinet. You will find packaged systems installed on rooftops or in areas where ground space is limited. Carrier-brand packaged units include both gas/electric furnaces, air conditioners and heat pumps. SEER ratings range from 13 to 15.5 while Annual Fuel Utilization Rating (AFUE) numbers for heating systems stand at 80.1. AFUE indicates the percentage of energy in the furnace fuel that gets turned into usable heat; an AFUE of 80, for example, means 80 percent of the fuel becomes heat that can be used in your home.
  • Furnaces: Carrier furnaces provide AFUE ratings between 80 to 98.5 for gas-burning models and 80 to 86 for oil-burning models. More advanced systems offer features that boost performance and efficiency, such as a modulating gas valve and variable-speed blowers.
  • Heat pumps: Heat pumps work on the principle of capturing heat and moving it from place to place using very little energy. Heat pumps can actually be reversed to provide cooling as well. This allows a single heat pump to provide both heating and cooling for convenience and space considerations. Carrier heat pumps are available in SEER ratings from 13 to 20.5, and in HSPF ratings (an efficiency measure for air-source heat pumps) from 9 to 13.


The fact that Willis Carrier, the man after whom this brand is named, was the architect behind the first modern air conditioning system, inherently signifies a commitment to excellence in product standards. Carrier’s history as an innovator in air conditioning means knowledge and expertise you can trust.
