Different types of HVAC Systems

You've done an energy audit of your home, added insulation, and hired a cooling or heating system specialist. Now it's time for you to pick the best HVAC contractor in the Washington system.


Systems of today have many more features than ever before, including variable fan speeds and various heating and cool stages.


  • Zoned Control System


Zoned HVAC systems heat or cool certain areas by controlling the flow of air through zone valves or zones dampers located in the vents or conduit work. Zoned systems are able to save you money by heating or cooling only the areas that are required.


  • Humidity control


You can also add dehumidifiers and humidifiers to your heating and cooling systems. These upgrades are highly recommended if you live somewhere very dry or humid. The ideal relative humidity for humans is around 50%.


These systems can adjust the humidity levels of a home's heating and cooling system to maintain a comfortable temperature. While your furnace or air conditioner has humidity/dehumidification systems built-in, you can't manage the humidity levels when the system is turned off. Separate humidity/dehumidification systems can be added if desired.


  • Heating and cooling


The US Department of Energy claims that modern heating systems can be efficient up to 97 percent, which means almost all of the fuel is converted into heat.


Warm air furnaces are those that distribute warm air via ductwork. It is one of the most popular heating systems in the United States. There are also boilers that heat water to heat steam radiators, forced-water heating systems with baseboard radiators, and electric heat. Propane and natural gas are used most often in furnaces. However, gas or oil can also be used in boilers.


  • System of cooling


There are many options for air conditioning systems today. Your house's environment and existing systems will influence what system you choose.


Central or whole-house air conditioning systems are essential for south residents. Northern residents have the option of portable window units that can fit inside windows for a few months. A ductless mini split, which is part inside and part outdoors, can be used by many people.


The three main components of an AC conditioner are the condenser, condenser, or evaporator. The compressor and condenser can be found on the exterior of an air conditioner while the evaporator can be found inside. Split systems are the most commonly used central air conditioning system in homes.


Evaporative coolers (also known as swamp coolers) cool outdoor air bypassing the liquid over water-saturated surfaces, which cause water to evaporate. They can be used in areas with high temperatures but low humidity, such as the southwest. The colder air is then forced into the house through the windows, while the warmer is forced out the doors. Cooling specific areas is possible with room air conditioners that can fit into windows or be placed in walls.


It is essential to choose the right size unit for air conditioning. It is not always advisable to have a bigger unit. A unit that is too large won't chill an area evenly. A compact unit that runs continuously will be more effective than one that cycles on and off all the time.


Retrofit Options for Heating & Cooling Systems


Maybe you don't have to replace your cooling and heating system. You can just make minor repairs. Many options are affordable and can help save you money.


Vent dampers are installed on gas- or oil-fired boilers or furnaces to prevent air loss up the chimney. In older systems, intermittent ignition devices shut off the pilot lights by turning off the boiler's heat when it is not in use. You can reduce the size of a large system by either reducing the size orifices or nozzles on oil-fired systems and/or the baffles on a gas-fired system.


HVAC Overhaul in a Deep Energy Retrofit

Radiators that are too hot can be removed. Modulating Aquastats for hot-water boilers can change the temperature to the outside temperature, which can reduce fuel expenses by up to 10%. Hot-water boilers use a time delay relay to allow hot water to travel through the system, without having to fire the boiler. An oil-fired system may also benefit from a barometric chimney damper. It stops heat from traveling up the chimney. You can find more information at the Department of Energy about retrofitting your oil-fired system and gas systems.
