Energy Efficient HVAC Systems for Healthcare Facilities

HVAC Los Angeles systems are vital in the operation of healthcare facilities. Among other functions, they heat and cool spaces; ventilate and filter indoor air; and control moisture levels to protect patients and staff from infection.


When selecting an HVAC system, consider energy efficiency, sound levels, price, and warranty coverage. Look for companies that provide manufacturer support and responsive technical assistance.

Air conditioners consume a significant amount of electricity during operation. In fact, they are among the largest contributors to household electricity bills in the United States, making them a major source of environmental pollution. This energy use can be mitigated to some extent by choosing an efficient model and regularly replacing air filters. It is also important to keep ducts well-sealed, and reducing the need for cooling by ensuring adequate insulation and using natural ventilation as much as possible.

An air conditioning system works by absorbing heat from the indoors and exchanging it with the outdoors. In its simplest form, it does this by blowing cool air across evaporator coils. The cold air causes the refrigerant to evaporate, releasing heat into the room and dehumidifying it. The air is then blown back outside through the condenser coil, where it cools again and absorbs more heat from the outdoor air, resulting in even more cooling and dehumidification. An expansion valve is then used to control the flow of refrigerant to ensure a consistent release of cool air into the home.

Most air conditioners leak hydrofluorocarbon refrigerants — powerful planet-warming gases — into the atmosphere. However, more sustainable refrigerants with lower Global Warming Potential ratings are being developed and produced. In addition, governments around the world have enacted strategies like energy conservation standards and labels, financial incentives, and legislation to drive the market towards more efficient equipment.

Today’s air conditioners do more than just cool the air; they often offer settings for air filtration, which removes allergens like dust particles, pet dander, and mold spores from the indoor environment. They can also help reduce indoor humidity, which is the source of mold growth and musty odors.

If you’re looking for a more eco-friendly way to cool your home, consider a smart AC unit that connects to Wi-Fi and optimizes the performance of your existing HVAC system. This can include alerting you to when the air filter needs replacement, and it can also be programmed to operate at a low-energy level during times of peak demand. In some cases, replacing older, less-efficient equipment with an ENERGY STAR-certified model can reduce your energy costs by up to 20 percent.


Furnaces are responsible for the majority of your heating needs in your home. They use a combination of passive air circulation and active combustion to warm up the house. Most furnaces today run on natural gas, propane or electricity. Older models used coal and wood to generate heat.

A thermostat signals the furnace to turn on, which opens a gas valve and activates the burner. This burns gas to produce heat, which is transferred to a blower and circulated through ductwork to warm up the house.

The combustion process in furnaces produces greenhouse gases that trap heat in the Earth’s atmosphere and contribute to climate change. The amount of greenhouse gases released varies depending on the type of fuel used. For example, natural gas releases fewer greenhouse gases than oil or propane. However, the extraction and transportation of these fuels also has negative environmental impacts.

Most homeowners have a forced-air gas furnace that uses ducts to transport the heated air throughout the home. The ducts can be made of sheet metal or insulated plastic flex duct. Unless they are properly sealed with mastic or foil duct tape, the ducts and plenum can leak conditioned air into unconditioned spaces in the home. This is a waste of energy that can increase your utility bills significantly.

Choosing the right furnace can help reduce your energy consumption and carbon footprint. Typically, the most environmentally friendly models have an AFUE (annual fuel utilization efficiency) rating of 90% or higher. This means that a gas or propane furnace converts 90% of the fossil fuel energy into heat, while 10% escapes through the chimney and other losses.

In addition to the AFUE, the size of your home and its construction can determine how efficient your furnace is. For example, larger homes typically require more energy to heat than smaller ones. The efficiency of your furnace is further reduced if the ductwork is leaky or if the house has insulation problems.

Heat Pumps

Heat pumps are an eco-conscious option that offer energy efficiency and eco-friendly heating compared to fossil fuel-based systems. They can aid in reducing greenhouse gas emissions linked to building heating and cooling on a significant scale. In addition, these units are able to help regulate electricity consumption through intelligent demand-side management and support renewable energy integration.

According to the IEA, buildings use 40% of Europe’s energy and emit 36% of the region’s GHGs. These figures represent a considerable opportunity for decarbonization, and heat pumps are one of the most important technology tools that can contribute to this goal.

This is because, compared to conventional boilers, heat pumps consume significantly less energy to provide the same amount of heating. Additionally, they are capable of providing backup heat in the event that primary heating sources cannot operate at full capacity due to weather conditions.

One of the main reasons why heat pumps are so efficient is that they utilize a simple refrigeration cycle to transfer thermal energy between a cool space and a warm one. As a result, they require less maintenance than other heating systems. Additionally, they have a longer service life and a lower operating cost than traditional boilers.

When used to replace conventional boilers, heat pumps can save homeowners a substantial amount of money. However, the exact savings will vary depending on the heating requirements of the home and local utility prices. In general, a heat pump will save homeowners between $1,500 and $3,000 per year.

Many homeowners have the misconception that heat pumps do not work in cold climates. This is false. In fact, they can provide effective and reliable heating in almost any climate with a few adjustments. However, this is also dependent on the size of the house and the climate in which it is located.

The ozone depletion (OD) impact category is presented in Figure 6. This impact occurs primarily because of refrigerants in the manufacturing and operation phases of the heat pump. OD is caused by the degradation of ozone molecules in the stratosphere. In the case of ASHP, this impact is higher than other technologies because of the increased use of raw materials like copper and steel.

Ductless Systems

Ductless systems have a cool, eco-chic vibe that sets them apart from traditional HVACs. They lack the ductwork that can cause energy to disappear through the air, and they’re often much more efficient than their ducted counterparts.

A ductless system’s indoor unit cools the air by blowing it over an evaporator coil, which collects and releases condensation. Then the cooled air is blown back into your home, and the cycle repeats. The units themselves are typically small and can be installed discreetly in a wall or ceiling. That makes them ideal for new additions, like garage apartments, bonus rooms and sunrooms. They can also be a smart choice for bringing cooling and heating to older homes with no room for ductwork, like attics and basements.

Unlike central air, which can heat and cool a whole house with a single system, a ductless system has its own indoor and outdoor units. These individual units can be used to create different zones for different temperatures. You can control each zone with a wireless or cable remote, and some models come with voice and Wi-Fi controls. They also feature inverter technology that automatically adjusts compressor speed to match cooling demands.

Most ductless systems are able to heat and cool spaces up to 1,500 square feet, depending on the size of the unit and how many BTUs it can process. Your HVAC associate can help you determine the proper unit size for your home, taking into account factors such as your flooring, insulation and ceiling height.

Since ductless systems don’t require a bunch of ductwork, they’re easier to maintain than a centralized HVAC. They’re less likely to suffer from leaks or obstructions in the ducts, and if you do run into a problem with one of the indoor units, it’s easy to isolate and repair just that particular unit.

Just like with your air conditioner and furnace, it’s important to choose a reputable HVAC contractor for ductless system installation, repairs and maintenance. Then you can be sure your HVAC system is properly sized, working efficiently and safely. A good technician can also make sure you understand how to use your new equipment and keep it in great condition.
