HVAC stands for heating, ventilation and air conditioning systems. This system is responsible for heating and cooling your home and includes products like furnaces, air conditioners, heat pumps as well as ductwork, thermostats and other home comfort controls.
While the world of HVAC might seem complicated, it doesn’t have to be confusing for homeowners. Once you learn a little more about how the systems work, the HVAC meaning and all the technical components will make more sense, and you can learn even more by watching this video that discusses HVAC and working with an expert dealer.
There are many moving parts that work to not only warm you in winter and cool you in summer, but also filter and purify your air to help protect you and your family from allergens, pollutants, and harmful chemicals. Breaking down the different parts of an HVAC system, or the heating and cooling products within homes, can help you to understand each system’s role in bringing you comfort throughout the year. Watch this video on how HVAC systems work to learn more details on heating and cooling systems and how you can achieve optimal comfort in your home and get more information on each system below.
Most people understand that a furnace heats a home, but don’t understand all the intricacies involved in the system. All furnaces consist of four main components: 1) burners that deliver and burn fuel, 2) heat exchangers, 3) a blower and 4) a flue that acts as an exhaust for gaseous by-products. A furnace generates heat by burning fuel and distributes the generated heat throughout the house.
An air conditioner draws heat energy out of the house and transfers it to the outside air. The most common setup for residential homes is a split system, which includes an inside-the-home evaporative heat exchanger and an outside condensing unit heat exchanger.
A heat pump is an energy-efficient option to consider if you live in a mild climate zone. It uses the outside air to heat a home in winter and cool it in summer. Heat pumps are often misunderstood by homeowners, especially as a cooling system given their name contains the word “heat.” In the simplest sense, a heat pump “pumps heat” from one place to another, moving heat out of your home when you want it cooler, and pumping heat into your home when you want it warmer.
An air handler most commonly works with a heat pump to circulate air throughout your home. If you’re searching for a traditional air conditioner or furnace, you won’t need an air handler as those systems have the internal parts needed to circulate air.
A ductless HVAC system or mini split is a heating and cooling system designed to deliver warm or cool air to a single room or several without the need for connective ductwork. Mini split systems are a great option for room additions, sunrooms, garages or areas of the home that need to be warmer or cooler. Ductless systems are a great option to heat or cool a single room in your home without the hassle of adding ductwork.
A thermostat, located inside your home, is a regulating device that allows you to control your indoor temperature. Thermostats are generally split into two classifications: traditional or connected controls. Basically connected, or smart thermostat controls, can integrate with other smart home systems and learn over time how to most efficiently heat and cool your home. Traditional thermostats are simpler — but several offer programmable features as well.
There are many ways to save on a new Trane HVAC system. Talk to your local dealer about how to save on local rebates, tax credits, and special, limited-time offers. Here are some of the main factors that affect the cost of a new heating and cooling system.
Region and climate matter when finding the right system for your home and saving energy. The heating and cooling needs will differ in the hot and humid south and cold north. Also, installation costs can vary by as much as 20% depending on where you live.
A large home will need a larger unit or even multiple systems to properly maintain a comfortable temperature — which of course will cost more than a smaller home. In addition, proper seals on windows and doors and the quality of your home’s insulation will affect your monthly heating and cooling costs.
Ductwork plays a crucial role in determining how comfortable your home is from room to room. When properly designed and installed, a duct system can maximize comfort and minimize energy use. If you’re installing a new HVAC system in a newly constructed home or replacing ductwork in a current home, adding ductwork will add as much as $2,000 - $3,000 to the total cost of your HVAC system.
If your new system is planned for a hard-to-reach space or if you live in a historic home that requires retrofitting, you’ll see your HVAC installation price increase. Only with an onsite evaluation will these kinds of costs be discovered.
Along with your traditional heating and cooling system, you have options to enhance the overall indoor air quality of your home with a Trane CleanEffects™ air cleaner or add climate zones with a ComfortLink™ II Zoning System or take advantage of the latest smart home, connected thermostat controls.
HVAC is very technical and it can be hard to make sense of all the acronyms, terms, and abbreviations. Here are a few top terms to help demystify the products to help you understand heating and cooling technology better – so that you can choose the HVAC system that is right for you.

Whether your HVAC system is new and still under warranty or over 10 years old; routine maintenance service can get you ready for the upcoming season, lower your energy bills, extend the life of your system, and catch problems before they become costly repairs.
Scheduled HVAC maintenance includes items such as the following:
It is easiest to remember to schedule maintenance for each system if you follow this standard:
Schedule an appointment in late summer or early fall, before the heating season.
Schedule an appointment in late winter or early spring, before the cooling season.
If your home’s heating and cooling systems are no longer keeping you comfortable, it may be time to decide whether to repair or replace your HVAC system. There are some warning signs that it may be time to replace your HVAC – or if your HVAC system is no longer under warranty and the repair costs are getting too high.
Replace your system when:
Replace your air conditioner if:
Replace your furnace if:
Replace your heat pump if:
Financial Tip: Follow the $5,000 Rule
Take the age of the equipment and multiply that by the estimated repair cost. If the number is more than $5,000, then you should consider replacing your unit.
Now that you know the basics, talk to your local Trane dealer for a detailed evaluation and recommendation for what heating and cooling solution is right for you.

If you’ve decided to invest in a cooling system for your home, you already know it’s a major investment, so you want to be sure you’re buying the right unit for your house.While there are several things to consider when deciding which AC unit to buy, perhaps the most important question you may be asking yourself: What size AC unit do I need?
Not only do you want to avoid wasting money on the wrong air conditioner, but you also don’t want to throw your money out the window each month, as the unnecessarily large AC unit burns up your energy bill.
Likewise, you don’t want to buy a unit that’s too small for your house, which means it will be running all the time to try and cool you down, eventually leading you to buy a second unit.
Thankfully, you can avoid guessing games and calculate the right size AC unit your house needs.
There are several things you will need to consider, all of which will affect the size of the AC unit you will need for your house:
To come up with a ballpark, the three most important numbers you need to know:
Tonnage actually has nothing to do with weight. A ton refers to the AC unit’s capacity to cool the air, in other words, how much heat the unit can remove in one hour.
That capacity is measured in BTUs or British Thermal Units. Why BTU? A long time ago, they determined it takes 286,000 BTU to completely melt one ton of ice in a 24-hour period. HVAC experts eventually divided that number by 24 hours and came up with 12,000 BTU/1-ton AC capacity.
Using that measurement, a two-ton AC unit will remove 24,000 BTUs, while a three-ton AC unit will remove 36,000 BTUs. Therefore, the more tonnage the AC unit is rated for, the more air it can cool down.
To get a rough estimate of the tonnage you will need from your AC unit, use the following calculation:
Square footage of your home x 25 (estimated energy to cool one square foot is 25 BTU) / 12,000 –1 = AC Unit Tonnage
For example, the calculations for a 1,200-square-foot home:
(1,200 x 25) / 12,000 –1 = 1.5 Tons
You would need a 1.5 ton AC unit for your house.
If you live in a drier or hotter region, don’t subtract 1.
For example, the calculations for a 1,200-square-foot home located in New Mexico:
(1,200 x 25) / 12,000 = 2.5 Tons
You would need a 2.5 ton AC unit for your house.
This table should give you an idea of what size AC unit you need, depending on the square footage of your house (located in a temperate climate region):
Square Footage BTUs per hour AC Unit Tonnage 450 to 550 12,000 1 Ton 550 to 700 14,000 1.5 Tons 700 to 1,000 18,000 1.5 Tons 1,000 to 1,200 21,000 2 Tons 1,200 to 1,400 23,000 2 Tons 1,400 to 1,500 24,000 2 Tons 1,500 to 2,000 30,000 2.5 Tons 2,000 to 2,500 34,000 3 TonOf course, all the other factors we previously discussed will also affect the unit you ultimately end up purchasing:
There are commonly two different types of air conditioning systems you can install in your home: a packaged unit or a split system.
The packaged unit air conditioner is the one most commonly associated with a central air system. With this system, the evaporator, condenser, and compressor are placed in one single cabinet. This cabinet is most often located on a concrete slab outside or on the roof. This type of packaged air conditioner usually includes electric heating coils or a natural gas furnace. This removes the need for an entirely separate furnace.
This type of system is most often used in homes that already have a furnace but no air conditioner installed. It’s the most cost-effective way to install air conditioning in a house.
With a split-system central air conditioning unit, an outdoor cabinet holds the condenser and compressor. An indoor cabinet holds the evaporator. This indoor cabinet may also hold the furnace.
While it’s fairly simple to come up with a rough estimate on the right size AC unit you will need for your house, ultimately, it’s safer and will save you money in the long run, if you work with an HVAC expert to determine the proper size.
Installing central air can cost you between $3,779 and $7,429, according to HomeAdvisor.com. So you want to make sure you’re buying the right unit the first time.
