HVAC systems provide air-conditioning, heating and ventilation. HVAC companies offer various equipment options to meet specific customer preferences and climate conditions.
Some people make the mistake of selecting an HVAC system based on sticker price alone. A better way to evaluate an HVAC system is to look at its warranty, features and services.
Energy Efficiency
Whether you’re cooling your home or heating it, your HVAC system takes up quite a bit of energy. Older units can use more power than their newer counterparts because they’re less efficient. However, by upgrading to a high-efficiency model, you can help cut down your electricity and fuel bills significantly.
Another way to boost your HVAC’s energy efficiency is to ensure it’s properly sized for your space. If your unit is too big or too small, it will be working overtime, using more energy than necessary. In addition to ensuring the right size, you can also take steps to improve your system’s energy efficiency by regularly changing the air filter and keeping the outdoor unit free from fallen leaves, debris, and other moisture.
Finally, opting for a refrigerant that requires less compression, such as R-410A, can reduce your system’s energy consumption. Additionally, installing a whole-home dehumidifier or humidifier can improve indoor air quality, further reducing your energy use.
Energy-efficient HVAC systems are designed to operate with lower greenhouse gas emissions, helping to combat climate change. They can also save you money on energy costs, as they’ll use less electricity to cool and heat your building. If you’re interested in creating more sustainability in your business, talk to an HVAC contractor about implementing an energy-efficient system. You may be able to find rebates on your purchase, too.
Durability
As building components, HVAC systems play a key role in the durability of structures. They regulate temperature, humidity, and airflow to enhance occupant comfort, while protecting the structural integrity of buildings and reducing operational costs. Additionally, they are responsible for creating a thermal boundary to keep outside air out and indoor air in. With advanced technologies and energy efficiency, HVAC contributes to the sustainability and longevity of buildings.
HVAC systems are an important investment in your home, and it’s only natural to want them to last as long as possible. However, the lifespan of any heating and cooling system largely depends on the type of unit and how well it is maintained.
Even the most high-performing furnaces, boilers, heat pumps, and air conditioners have a limited life expectancy. From an expired warranty to inconsistent temperatures, it’s important to be aware of the signs that indicate it might be time for a new unit.
As a homeowner, you can greatly extend the lifespan of your HVAC system by performing regular maintenance and repairs. This will help to keep the unit running smoothly and efficiently and reduce the risk of unexpected breakdowns and repairs. Moreover, by keeping the system properly insulated, you can save money by lowering the frequency at which it needs to run. This will significantly prolong its lifespan and save you money in the long run.
Noise Reduction
Noise from HVAC equipment can disturb occupants, distract them from work, and cause sleep disturbance. Fortunately, effective HVAC noise reduction strategies can help create serene and comfortable indoor spaces that support productivity and wellbeing.
One of the most common sources of HVAC noise is airborne noise, which is caused by air turbulence. High-quality air filters can reduce this problem by minimizing the movement of particulate matter and dampening noise. Air filtration also improves indoor air quality by reducing pollutants and allergens that can contribute to respiratory problems.
Structural noise is another common source of HVAC sound, especially in homes with metal ductwork. Noisy ductwork can make a whistling sound or carry conversations from room to room, which can be particularly irritating if the vents are located close to sleeping areas. Stiffening ducts with fiberglass insulation or using sound absorbing duct liner can help reduce structural HVAC noise.
For noisy ductwork, the best solution may be to install an acoustic barrier wall around the ductwork. These are available in many forms, including acoustic foam, and can be installed easily by a professional. They can be painted or decorated to blend into the décor. There are also acoustic noise-reducing sprays, blankets, and sheets that can be applied to the exterior of HVAC ducts. These products can effectively silence structural HVAC noises and block leaking air from escaping, as well as reducing the amount of heat that is transferred through the ducts.
IAQ
The HVAC system is responsible for improving indoor air quality (IAQ) by supplying adequate ventilation with filtration and providing thermal comfort. The ventilation and filtration systems also minimize the infiltration of outdoor pollutants.
Various bacteria, viruses and molds thrive in high temperatures, while certain chemicals, such as formaldehyde, ozone and carbon monoxide, have higher concentrations at warmer temperatures. These pollutants and others can lead to symptoms such as headaches, fatigue, respiratory ailments, allergies and nausea in occupants.
Poor IAQ can have long-term health effects in addition to immediate symptoms. These include respiratory diseases, heart disease and cancer. Some of these problems may not show up until years after exposure, while others can be very severe and even life threatening.
Many studies indicate that people are more satisfied with the environment in which they work and live when the humidity is between 50% and 60%, the temperature is moderate and the level of contaminants is low. Many HVAC systems have been designed to promote the achievement of these goals in order to improve IAQ.
In a forced-air HVAC system, the blower motor in an air handler unit pulls air over the cooling and heating components, conditioning it before it is pushed through the ductwork of the building. In addition to the cooling equipment, the system may also have a furnace to provide heat.
