HVAC systems are vital to residential and commercial buildings, including single-family homes, apartment complexes, hospitals, and office spaces. They promote healthy and productive environments for building occupants while reducing energy consumption and costs.
Smart HVAC systems offer energy-saving features like programmable thermostats and zoning solutions. They can also help to reduce operating expenses by providing timely preventative maintenance. Contact HVAC Lexington now!
If you’re considering upgrading your home heating system, you have several options. But before you decide what unit to purchase or hire an HVAC service, you need to understand what HVAC systems are all about. HVAC stands for heating, ventilation, and air conditioning, but they’re much more than a way to heat or cool indoor spaces. Their role is to regulate and improve indoor air quality for improved health, comfort, and productivity.
To do this, HVAC systems are comprised of several key components that work together to maintain ideal home conditions. They start with the air return system, which sucks in outdoor air and draws it into the main system. From there, it’s either sent to be heated or cooled and has excess humidity removed before it’s directed into your space. It’s then circulated through a network of ductwork in a home or a series of vents for a ductless system.
The most important factor to consider when selecting a home heating system is the BTU capacity. A higher BTU capacity will provide more heat, but it’s also more expensive to operate. To find the right balance, consider working with an HVAC professional to calculate your ideal BTU capacity for your home.
Another key feature to look for is an AFUE rating, which measures how efficiently a gas furnace or boiler operates. A higher AFUE rating means less fuel is wasted while producing more heat, which in turn saves you money on your energy bills.
Finally, you’ll want to take a close look at the thermostats in your home. Thermostats are the brain of the HVAC system, and they’re designed to read your preferences and respond accordingly. You can choose from manual, programmable, and smart thermostats that offer the ultimate in convenience and control.
Cooling
In the cooling phase, HVAC systems work to remove heat from indoor spaces and transfer it outdoors. The process is accomplished by absorbing, transporting and releasing heat through a series of cycles. This helps regulate temperature and humidity in indoor spaces, while improving ventilation and removing allergens from the air. HVAC systems can be sized to meet the specific needs of individual homes or businesses, depending on factors like climate and existing infrastructure.
Typically, a conventional HVAC system will combine an air conditioner that’s located outside with an air handler inside a property. However, other options exist for properties that don’t have ductwork, such as a split system design with an air conditioning unit located outside and a fan/coil that’s situated in the interior of the home. HVAC system models also vary in their cooling stages, with higher-efficiency units offering greater energy savings.
The components of a HVAC system include the air conditioning equipment itself, ductwork and thermostats. The air conditioning equipment can be an air conditioner, furnace, heat pump, or a hybrid combination of these devices. Similarly, the ductwork can be conventional or internet-connected (smart) — the latter offering advanced control via a mobile app. Finally, the thermostats will be either manual, programmable or smart, with the latter allowing you to adjust settings while you’re away from your property.
When you’re looking for an HVAC solution that can meet the unique heating and cooling needs of your home or business, consult with a local dealer. They’ll help you choose the best HVAC model for your surroundings, then recommend a repair or replacement plan that fits your budget.
Ventilation
Ventilation is the movement of outdoor air into a building or room and its distribution within the space. Its general purpose is to provide healthy air for breathing by diluting contaminants that originate in the building and removing them from the indoor air (Etheridge & Sandberg, 1996).
The ventilation system may consist of either natural or mechanical methods. The former relies on a network of openings in the walls, floor and roof of the building for the movement of outdoor air, while the latter primarily uses fans to move air through the ductwork. It also includes the use of filters to remove pollutants from the indoor air and to control humidity.
Ventilation systems should be designed to ensure that their supply and exhaust rates are appropriate for a given building or space. For example, a ventilation system in a school needs to be able to react quickly when the number of occupants increases, to ensure that outside air is brought in at the right volume to match the number of people inside. It should also be able to control the amount of humidity in the air, and avoid moisture build up which can lead to mold and other health problems.
The best way to ensure a ventilation system is doing its job properly is to have it built into the overall design of a building, rather than being an add-on later on. The HVAC engineers at Greens Energy Services can help with this process.
Modern mechanical ventilation systems are often based on demand-driven controls, with sensors such as CO2 and humidity being used to detect occupancy or other changes in conditions. When these sensors are activated, the ventilation system is triggered to act, increasing or decreasing the flow of air through the building depending on the need. This approach helps to reduce energy consumption, as well as ensuring that moisture-laden air is not exhausted into spaces where it can cause damage or that odors are not being expelled where they shouldn’t be (such as from kitchens to the rest of the building).
The ability to adapt to changing conditions is a key benefit of using a mechanical ventilation system. It is also important to have a system that is able to work with different types of buildings, as there are often differences in air quality standards across the globe. For example, in some countries the use of a ventilation system is mandatory to protect employees and customers from harmful microbes.
Maintenance
Just as you value your car enough to get regular oil changes, you should value your HVAC system enough to have its maintenance done. An HVAC system that has been poorly maintained will work harder for longer periods of time to give you the same results – and that can lead to expensive energy bills, costly repairs or a sooner-than-necessary system replacement.
With a preventative maintenance plan, you can keep your heating and cooling system running at peak performance for years to come, saving you money on utility bills. In addition, a professional technician can identify potential problems that might require repair or a system replacement and catch them early, preventing the problem from getting worse.
During a maintenance appointment, an HVAC technician will thoroughly clean evaporator and condenser coils and fan blades to ensure optimal function and efficiency. They will also inspect the air ducts and clean them as needed, checking for leaks or blockages and ensuring proper air flow. The blower motor and compressor are lubricated to reduce strain on the system, and the thermostat will be inspected and cleaned, as well as calibrated for more efficient operation. In addition, carbon monoxide detector and fire alarm batteries will be replaced if needed, and the AC condensate drain line will be cleaned to avoid clogs and reduce the risk of mold.
The best time to schedule a preventative maintenance check is before the summer heat arrives or the winter cold hits. This is when your HVAC system will be working hardest, so a breakdown during one of these extreme weather events is the last thing you want.
Additionally, if you wait to have your system checked during these times, the demand for service will be higher and the technicians may have to work overtime to meet that need. This will result in a longer wait time for you, and you could be left at the mercy of the scorching summer heat or the bitterly cold winter air until your HVAC system can be repaired or replaced. With a proactive approach to maintenance, you can avoid these inconveniences entirely.
