Of the common mistakes mentioned above, buying an incorrectly sized HVAC system can be the most detrimental, as it can lead to several serious consequences.
Oversized Heating and Cooling System Issues
HVAC System Short-Cycling
If the heating or cooling system is too large for the home, it will cool or heat the space too quickly, then shut off. Because it runs for such a brief period, it doesn’t effectively remove humidity or achieve a uniform temperature distribution throughout the space. This leads to frequent on and off cycles, or “short cycling.” This, in turn, results in increased wear and tear on the equipment, higher energy bills, and reduced comfort due to uneven temperatures. This also reduces the system’s ability to properly dehumidify the air, making the home feel clammy and uncomfortable.
Compounded Inefficiencies
An oversized system will also lead to wider temperature swings, especially in perimeter rooms. The excess cooling or heating produced by an oversized system leads to uneven distribution and fluctuating temperatures, leading to a compounding inefficiency effect as people often use additional portable heating and cooling devices to compensate for their poorly designed system.
Undersized HVAC System Issues
Inability to Reach Desired Temperature
A solution too small for heating and cooling your home may struggle to meet the thermostat setting, especially on very hot or cold days. Some rooms may feel hotter or colder than others. A properly sized HVAC system should be able to reliably maintain the air quality and comfort of your indoor spaces with the utmost efficiency.
Inconsistent Temperatures
With an undersized system, some rooms may be too warm while others are comfortable, leading to fluctuating temperatures throughout the home or building.
Excessive Humidity
If the capacity to properly dehumidify the air is not possible due to undersizing, the indoor environment will feel muggy and damp, even if the temperature seems right.
Constant Running
If undersized, the HVAC system must work harder. It will run continuously without cycling off, never reaching the thermostat set point. This wastes energy and shortens the system’s lifespan. To determine if an HVAC system is properly sized, a professional should perform a load calculation taking into account the square footage, insulation, windows, and climate. Choosing the right size system is crucial for comfort, durability, and the efficiency of your HVAC system.
Additional Effects of Failing to Choose the Right HVAC System
Lack of Home Comfort and Air Quality Issues
Oversizing will lead to wider temperature swings, especially in perimeter rooms. Short-cycling also reduces the system’s ability to properly dehumidify the air, making the home feel clammy and uncomfortable. Undersized systems may struggle to maintain a consistent temperature, leaving some rooms too hot or cold.
High Energy Bills Impacting Total System Cost
An undersized HVAC system has to work harder to try and meet the cooling or heating demand as it attempts to maintain the temperature of the air throughout your home, thereby using far more energy than necessary. This can lead to unusually high utility bills. Conversely, an oversized system will cycle on and off frequently, also wasting energy.
Reduced Equipment Lifespan
The excessive wear and tear caused by short-cycling or overworking can significantly reduce equipment lifespan. This means more frequent and costly repairs or replacements down the line.

- The SEER rating is calculated by dividing the cooling output of the AC system (in British Thermal Units, or BTUs) over a typical cooling season by the total electric energy input (in watt-hours) during the same period.
Understanding SEER Ratings:
- Higher SEER Numbers: A higher SEER number means greater efficiency. Modern air conditioning units typically have SEER numbers ranging from 13 to 25+. Older systems might have a SEER number of 6 or lower.
- Cost Implications: Generally, systems with higher SEER numbers are more expensive upfront but can provide significant cost savings in the long run due to lower energy costs.
- Minimum SEER Ratings: Different regions may have different minimum SEER numbers due to the varying climate demands. For example, as of 2023, in the United States, the minimum SEER number for new AC units ranges from 14 to 15, depending on the region.
Why SEER Matters:
- Energy Efficiency: Systems with high SEER numbers indicate more efficient use of electricity, which can lead to lower electricity bills, especially in regions with harsh summers and extensive cooling system use.
- Environmental Impact: Efficient AC units reduce peak load demand on power grids and can help reduce emissions associated with electricity production, especially in areas where non-renewable energy sources predominate.
- Comfort and Value: Investing in a high-SEER system not only ensures better cooling performance but can also increase the resale value of a home and improve indoor comfort with better system controls and features.
SEER and Heat Pumps:
- For heat pumps, SEER numbers measure efficiency in the cooling mode. Heat pumps also have HSPF (Heating Seasonal Performance Factor) ratings to measure their efficiency in heating mode.
When selecting a cooling system or heat pump, it’s important to consider both the SEER number and other factors such as the size of your home, your local climate, and the overall system cost. Often, consulting with a professional HVAC contractor can help determine the most appropriate system for your needs.
AFUE
AFUE stands for Annual Fuel Utilization Efficiency. It is a measure used to rate the efficiency of heating equipment, particularly furnaces and boilers. The AFUE rating is expressed as a percentage and indicates how efficiently a heating unit converts fuel into heat over a typical year. Essentially, it measures the amount of heat produced for every dollar of fuel consumed.
How AFUE Works:
- 100% AFUE: This would mean that all the energy from the fuel is being converted directly into heat. However, this level of efficiency is not practically achievable due to energy losses such as exhaust and radiation.
- High vs. Low AFUE: An AFUE of 90% means that 90% of the energy in the fuel becomes heat for the home and the other 10% escapes up the chimney or elsewhere. Older, less efficient systems can have AFUE values as low as 50-60%, meaning that nearly half of the energy is wasted. Modern, high-efficiency systems can achieve AFUE ratings above 90%, with some reaching up to 98.5%.
Importance of AFUE in Heating and Cooling:
- Cost-Effectiveness: The higher the AFUE rating, the more efficient the heating system is, which generally translates into lower fuel costs. Homeowners investing in high AFUE-rated systems may see a reduction in their heating bills over time.
- Environmental Impact: Higher efficiency ratings also mean fewer emissions since less fuel is wasted. Thus, systems with a higher AFUE are generally better for the environment.
- Regulations and Standards: In many places, there are minimum AFUE requirements for new installations to ensure energy conservation.
Selecting a Heating Solution: When choosing a new furnace or boiler, the AFUE rating is an important factor to consider alongside other factors such as the type of fuel used (natural gas, oil, electricity), the size and layout of the home, and local climate conditions. Systems with higher AFUE ratings may cost more upfront but can provide savings in the long term through reduced energy usage.
In summary, AFUE is a critical indicator of a heating efficiency and plays a significant role in the decision-making process for purchasing new heating equipment. It does not, however, apply to cooling systems, which are typically evaluated based on different metrics like SEER (Seasonal Energy Efficiency Ratio) for air cooling systems.
HSPF (Heating Seasonal Performance Factor):
HSPF is specific to heat pumps and measures their efficiency over an entire heating season. Like SEER, a higher HSPF rating signifies greater energy efficiency and cost savings.
ENERGY STAR Certification:
The Environmental Protection Agency’s (EPA) stringent energy efficiency standards are met by HVAC units with the ENERGY STAR certification. Choosing ENERGY STAR-certified products ensures superior energy efficiency, reduced energy consumption, and utility rebates or incentives eligibility.
Environmental Impact:
Reduced Energy Consumption:
Energy-efficient HVAC units consume less energy to provide the same level of heating or cooling, resulting in reduced demand for electricity or fossil fuels. These units help mitigate greenhouse gas emissions and combat climate change by lowering energy consumption.
Use of Eco-Friendly Refrigerants:
Many modern HVAC units utilize environmentally friendly refrigerants with lower global warming potential (GWP) and ozone depletion potential (ODP) than traditional refrigerants such as R-22. Opting for units with eco-friendly refrigerants minimizes environmental harm and supports efforts to protect the ozone layer.
Advanced Technologies:
To maximize energy efficiency and lessen negative environmental effects, certain HVAC systems use cutting-edge technologies, including dual-stage heating and cooling, variable-speed compressors, and smart controls. These technologies enhance efficiency, improve comfort, and contribute to overall sustainability.
Life Cycle Analysis:
Consider the entire life cycle of an HVAC unit, including manufacturing, transportation, installation, operation, and disposal. Energy-efficient units with longer lifespans and minimal environmental impact throughout their life cycles offer superior sustainability benefits compared to less efficient alternatives.
By prioritizing energy efficiency ratings and considering environmental impact factors, you can select an HVAC unit that delivers optimal comfort and performance, reduces energy consumption, lowers operating costs, and minimizes environmental footprint for a more sustainable future.
Specifications and Sizing
When selecting the right HVAC unit, specifications and sizing are paramount considerations that can significantly impact the system’s performance, efficiency, and overall effectiveness in maintaining indoor comfort. Let’s delve deeper into these crucial aspects:
Heating and Cooling Capacity:
One of the primary specifications to consider is the heating and cooling capacity of the HVAC unit, measured in BTUs (British Thermal Units) or tons. This specification determines the system’s ability to heat or cool the space it serves adequately. Properly sizing the unit involves calculating the heating and cooling loads of the building, considering factors such as square footage, insulation, windows, occupancy, and climate conditions.
Of the different types of HVAC solutions available, the one you select must be capable of producing enough BTUs to efficiently meet the demands of the calculated requirements for your indoor space.
Airflow Requirements:
Another essential specification is the airflow capacity of the HVAC unit, which ensures proper ventilation and distribution of conditioned air throughout the space. Factors such as duct design, air filters, and fan speed play a role in determining the airflow capacity needed to maintain comfort levels and indoor air quality.
Energy Efficiency Ratings:
Keep a close eye on HVAC units’ energy efficiency ratings, such as the heating unit’s AFUE (Annual Fuel Utilization Efficiency) and cooling unit’s SEER (Seasonal Energy Efficiency Ratio). In the course of your selection process, look for systems with high SEER and AFUE ratings as they indicate greater energy efficiency which equates to lowering energy consumption and operating costs. Energy-efficient units save money and reduce environmental impact by minimizing greenhouse gas emissions.
Compatibility with Building Infrastructure:
Consider the compatibility of the HVAC unit with existing building infrastructure, including ductwork, electrical systems, and control systems. Ensure that the unit’s specifications align with the requirements of your space and that any necessary modifications or upgrades can be accommodated seamlessly.
Noise Levels:
Evaluate the HVAC unit’s noise levels, especially if noise is a concern in residential or commercial settings. Choose models with lower decibel ratings or features such as variable-speed motors and sound-dampening technologies to minimize noise disruptions while maximizing comfort.
While many systems are suitable for homes and offices, system placement can be a critical component to managing noise levels. It’s important to note, however, that not every HVAC system offers seamless integration into your setting. From the wide range of HVAC solutions available, the right choice for your home or office will be unique to the unique specifications of your environment.
As an example, ductless mini-split units are great for zone control and new additions, but some of the mechanical components of that solution will be physically present in the space occupied. These units will produce a certain noise level in that space during operation. The little nuances like this are the things that must be considered in the quest to find an HVAC system that will not only meet your needs, but bring you many seasons of great comfort and reliable performance.
