Check Out These Frequently Asked Questions About Home Heating and Cooling Systems

HVAC (heating, ventilation, and air conditioning) systems are such a central part of virtually every modern home. They consume more energy than any other appliance in the house and generally require more upkeep. They also manage air quality, control humidity, and keep the home comfortable all year round, though, so it’s hard to imagine living without them.

Yet most homeowners don’t know much about these systems that are essential for their homes. So when it comes time to replace that ancient furnace or upgrade to a more efficient AC, or even get a basic tune-up, many people are at a loss. That’s why this article will answer some of the most commonly asked questions about HVAC systems.

What Kinds of Different Central Heating Systems Are There?

The three main types of central heating systems are furnaces, boilers, and heat pumps. Furnaces use natural gas, oil, or electric burners to provide heat, which is pushed through the home’s air duct system to every room in the house. These typically share the same air ducts used by the AC system but are separate, standalone units. 

Boilers are akin to furnaces in terms of how they produce heat, but instead of heating air, they heat water. In some cases, the hot water (or steam) is then pumped throughout the home to radiators, baseboard heaters, or some other form of radiant heating system installed in each room. 

Heat pumps, like traditional furnaces, heat air and pump it through the home’s ducts - but instead of converting fuel or electricity into heat, they absorb existing heat energy from outside and transfer it indoors. Heat pump systems can use the same process (in reverse) to cool the home, eliminating the need for two separate systems.

What Are Some Options for Ductless Cooling & Heating?

hvac The two main options for ductless heating and cooling systems are window-mounted units and ductless mini-split systems. 

Window-mounted AC/heater units, as the name suggests, are one-piece systems installed in a window frame. These operate on the same principle as heat pumps - transferring heat energy between spaces rather than producing it outright. These are most common in apartments, mobile homes, and other tiny homes.

Ductless mini-splits are miniature versions of traditional heat pump systems, with one unit inside and one outside, connected only by electrical wires and refrigerant piping. The indoor unit blows air directly into a given room in these systems. As such, a home that uses mini-splits will need multiple units installed throughout the house. This translates to a higher up-front cost but much greater efficiency in the long run.

How Often Do Heaters and Air Conditioners Need To Be Serviced?

hvac Heater and air conditioner service should ideally be performed twice a year - once in the spring and again in the fall. AC maintenance in the spring will ensure that the system is ready for the heat and humidity of summer. In the fall, heater service will prepare the plan for the cold winter months - this is particularly important in a place like Austin, which can experience both seasonal extremes.

Air conditioner and heater maintenance vary somewhat in the specific tasks performed (except in heat pump systems, which serve both functions), but the general idea is the same. The unit is cleaned, electrical systems are checked for anomalies, safety mechanisms are tested, components are lubricated, and the whole system is given a general tune-up. All in all, no matter what kind of system the home has, bi-annual service visits from a professional are arguably the best thing homeowners can do for their HVAC systems.

Quick Facts About Heating Technology

The History of Central Heating

One of the first things needed to survive the dangers presented by nature is a good shelter from the elements. Humanity’s ancestors innately knew the struggles of surviving against nature. In modern society, it is easy to overlook the necessity that homes represent. Modern homes have become so much more than just a barrier between humans and the elements. 

Probably the thing that most separates modern dwellings from that of earlier societies is the ability for humans to heat their shelters. Cold has always been one of the things that make humans struggle and suffer, but in modern homes, humans are protected from the cold and even comforted by the environment that they can create for themselves. Here are some facts about the development of modern heating systems that people enjoy today. 

Who Invented Central Heating?

Throughout history, humans made use of fire to warm themselves and they quickly learned how to bring fire safely inside their dwellings to take advantage of it. But, it wasn’t until the Roman Empire that humans figured out ways to heat their buildings indirectly. 

The earliest examples of central heating are the ruins of Roman baths that date back at least 2000 years. These baths were cunningly engineered to provide an activity for the empire’s wealthy citizens. The baths had simple but revolutionary designs. The floor of the bath was supported on pillars so that it was about two feet above ground level, similar to a crawl space. 

At one end of the opening below the floor, a fire was kindled and tended. The heat and smoke were drawn underneath the floor by cleverly placed flues that were built into the walls. This allowed temperatures inside the bath to reach up to 120 degrees. 

What Was the First Modern Heating Invention?

Up until the 1800s, heating a home was simple. Fuel was burned, heat was released, and the dwelling warmed up. It wasn’t until the Industrial Revolution that people started to use physics as a means to distribute heat. 

In the 1850s, Franz San-Galli invented the first hot water radiator. With the recent developments of steam power, he decided to harness that concept to help heat homes. The first radiator systems were similar to what is used today. Water was heated in a central boiler and pumped to radiators around the home to distribute heat. 

Then, in 1885, Dave Lennox further advanced home heating with the world’s first steel coal furnace. This invention moved heat through the home by the process of natural convection. It carried warm air up to various rooms in the house from a basement furnace through a series of ducts. 

When Did Thermostats Come Into Play?

The most important part of a heating system is the thermostat. Without a thermostat, a home’s occupants have no way of actually adjusting the temperatures. The first thermostat was invented in 1830 before most buildings were even outfitted with heating systems. The first thermostats were made of two dissimilar metals joined together that bent when heated.

The technology for thermostats wasn’t recognized for its value in central heating until 1885 when electric thermostats were used to signal servants to stoke the fires when the room got too cool. Some systems had elaborate pulley systems that would allow users to open or close flues remotely. But, thermostats wouldn’t come into popular usage in most buildings until about 50 years later.
