What Can You Expect When You Hire an HVAC Contractor?

 HVAC systems warm indoor spaces in the winter and cool them in the summer. In addition to your air conditioner and furnace, HVAC includes combined systems like heat pumps and indoor air-quality equipment like air purifiers. It also encompasses the control systems and smart thermostats that help everything work together. Read on for an overview of how HVAC systems work. 

What Does HVAC Stand For? HVAC stands for heating, ventilation, and air conditioning. It refers to the systems that regulate and move heated and cooled air throughout residential and commercial buildings, from homes to offices to indoor stadiums. Although there are many options when it comes to HVAC systems, they all work similarly, taking in fresh air and using a mechanical ventilation system to heat or cool it to a desired temperature. HVAC units also can control humidity levels and improve air quality through air cleaners that capture bacteria, spores, and virus-sized particles. The HVAC technician who comes to your home for a pre-installation evaluation will help you determine which system and options are best for you and your home. please go here Heating and Cooling get another more service.

How Does an HVAC System Work? HVAC systems are designed to move air, heating or cooling an indoor space in the process. These systems generally have three major elements: a heating unit, cooling unit, and duct to move the air. Bright Hub Engineering explains that an HVAC system starts with the ventilation that brings fresh air into a building. Natural ventilation takes air from open windows, doors, or cracks and uses pressure differences to force the air through a building. With today's tightly sealed homes and offices, this requires the use of fans, blowers, filters, and ducts.

Heat Pumps_ A heat pump works similarly to a central air conditioner and is based on the same idea that heat is always attracted to cold. To cool the air, heat is absorbed by the refrigerant and expelled out of the building. To produce warm air, a heat pump draws cold outside air over even colder refrigerant. Heat is then drawn into the refrigerant, which heats the coils. The air is drawn over those heated coils, where it rises to the desired temperature and is blown into the home.

Air Conditioning Systems_ To cool air, the fan in an air conditioning unit from Frigidaire, Coleman, and other HVAC companies draws the air in and forces it over the evaporator’s coils. Filled with refrigerant, these coils draw heat from the air, cooling it. Next, the air moves into the air handler, where a blower sends it into the ducts. As the cool air moves through the ducts, any noxious gasses produced during the process are expelled through the flue.

Furnaces_ To heat a building using a gas furnace, an HVAC system draws air in through the ducts and forces it into the furnace, according to HVAC dealer Ingram's Water & Air Equipment. When the furnace is running, the combustion chamber heats the heat exchanger to the designed temperature. Air is pushed through the exchanger, heated, and blown by the motor through the ducts and back into the house.

Types of HVAC Systems: Each HVAC system varies depending on the heating and cooling needs of a home, where that home is located, its age, its existing ductwork, its heating and cooling needs, and other factors. As a result, an HVAC can take any number of forms. Your HVAC technician will help you determine which of the following best meets your needs.

Hybrid Heat Pump_ In this scenario, the central heating system includes an electric heat pump that works in conjunction with a furnace. In milder times of the year like the spring and fall, the heat pump heats the home. During weather that's too cold for a heat pump to operate effectively, the furnace takes over. This hybrid system, also known as a dual-fuel system, saves money because it costs less to heat the home with a heat pump than a furnace.

Split System_ Also referred to as a forced-air system, a split system has one unit inside the home and one outside. This setup can consist of a furnace and air conditioner, an air handler and heat pump, or a furnace and heat pump. Which configuration is best for your home will depend largely on where you live. For example, the furnace and heat pump setup works best in very cold climates.

Ducted Mini-Split_ A ducted mini-split system uses tubes instead of larger ducts to move air into a room from an outdoor compressor and condenser. This solution is best for homes where there isn’t a lot of room for traditional ductwork. Compared to ductless mini-split systems, ducted mini-splits have the advantage of better air circulation.
