Understanding Your HVAC System: Heating, Air Conditioning & Ventilation


Your HVAC (heating, ventilation, and air conditioning) system is the system or combination of system used to provide a comfortable temperature in your home and maintain high levels of air quality. As a homeowner, it is important to understand the key roles your HVAC system plays and how they operate in order to get the most out of your system.

The heating component of your HVAC system provides a warm climate for your home in the cooler months of the year. Today, the most popular type of heating system is the forced air system, but many homes also use radiant heat systems and geothermal heating systems, among others. In all of the systems, heat is created at a central source and distributed through the home via different means.

Your HVAC system plays an important role in maintaining the your home’s indoor air quality. Ventilation helps circulate and purify air, control moisture levels, remove unwanted smells, and prevent air stagnation.

Air Conditioning
Your HVAC system is also in charge of keeping you cool during the warmer months. There are several different types of AC units, each with their own pros and cons. Whether you have central air (used in conjunction with forced air systems), split or ductless AC units, window AC units, or portable AC units, the process that each system uses to cool your home is similar.

With temperatures dropping, your air conditioner is likely the last thing on your mind. What many homeowners don’t know is that fall is an ideal time to purchase a new air conditioning system. Below are a few advantages to buying a new air conditioner now instead of waiting until next cooling season, along with tips for protecting your unit at winter approaches.

Avoid installation delays.

The average lifespan for an air conditioning system is approximately 15 years, although it can vary based on usage, maintenance, and environmental factors. If your current air conditioner is nearing or past this mark, you should probably expect to replace your unit in the next few years, if not sooner. Purchasing a new system now instead of waiting will prepare you for next cooling season, and set you up for lower cooling bills.

When you buy an air conditioner in the summer months, you may experience installation delays, leaving you to suffer through the heat longer. Air conditioning installation is in high demand in the summer, and your HVAC contractor may not be able to install a new unit for you right away. If a new air conditioner is in your future, you can avoid delays and minimize your discomfort by purchasing and installing one in the fall instead of waiting until next summer.

Experience more frequent repair needs.

If your air conditioner is breaking down on you often, this can be a telling sign that its time may be up soon. If the repair costs for your current system equal 25% or more of the price of a new system, now is the time to upgrade. Buying a new air conditioner now can save you the time and hassle of having to do so quickly and suddenly in the future, when your system gives out for good.

Time to research your options.

When air conditioners break down unexpectedly in the heat of summer, homeowners feel rushed to decide on a unit because they need cooling quick. Save yourself from making a hasty purchase decision by buying an air conditioner before your current one breaks down.

Winterizing your central air conditioner prevents rust damage and keeps critters from nesting inside mechanical parts. Winterization of your HVAC unit is a straightforward do-it-yourself home improvement project. It takes just a few minutes of your time to complete. By following these simple steps, you can help keep your central air conditioning unit clean and in top working condition for summers to come. The best time to prep your HVAC unit is early fall, just before you close the windows and turn on the heat.

1. Remove leaves, twigs and grass clippings. Use a garden hose to rinse the outdoor air conditioner, removing droppings, bugs, dirt and dust. Allow the HVAC unit to dry completely.

2. Locate the electrical circuit. It usually has a plastic or metal lid. Remove the lid and flip the switch to cut power supply. This prevents the unit from turning on during a warm winter day, which keep water out of the unit that could freeze overnight and damage your HVAC unit.

3. Install tubular foam or rubber pipe insulation with tees and elbows around pipes to protect against freezing. Cut the foam to fit by length and diameter of the pipe. Place tees and elbows first.

Advantages of Central Air Conditioning Systems

  • Better Air Quality in Your Home
    You might think that using a couple of room air conditioners in strategic places around your house is just as good as central air, and likely to be a lot cheaper. However, room air conditioners lack a key benefit of central air conditioners: they don’t filter the air they’re cooling. Central air conditioners use the ductwork in your home to circulate filtered air throughout the building, raising the air quality significantly. Cleaner air comes with various health benefits for homeowners. It can help prevent respiratory ailments, improve your sleep quality, and lower your likelihood of being affected by allergies. Just make sure that you’re changing the filters in your air conditioner at least once a month.
  • Less Mold
    Having fresh air circulated throughout your home can do more than improving your health. It can also help keep your building healthy and structurally sound, by preventing the damp conditions in which mold flourishes. When you have central air conditioning, your home will be at lower risk from mold than it would be otherwise. Your building will be stronger, and you’ll be free from the health hazards that come with certain types of mildew.
  • Combine Your Heating and Cooling Systems
    People often think that the prospect of putting in a whole system of ductwork just for cooling seems like a little too much work—and they’d be right if that were the only purpose of ductwork. However, it’s important to remember that the “H” in HVAC stands for heating. Many systems come with both heating and air conditioning options so that you can enjoy total control over the climate in your home throughout the year.
  • Save Overall Energy
    It’s true that a central air conditioner might technically use more power than having one or two room air conditioners in the places you frequent most. However, if you want to be truly comfortable during periods of warm weather, you’ll need to make sure that you have air conditioning available in every part of your house. While one or two room air conditioners is certainly cheaper than installing a central system, having a separate room air conditioner in every single room certainly isn’t. Furthermore, it’s worth noting that central air conditioners tend to have much higher EER (Energy Efficiency Ratios) than window units, which means that a central air conditioner will save you money in the long run when compared to multiple window units. When you factor in how much more efficient a central heater is than a typical gas furnace, adding an HVAC to your home makes even more economic sense.

The Benefits of Having Central Heating Systems in Your Home


Central heating, or heating that is propelled through sealed air ducts and released through vents for a thorough and even heating experience, is the best form of technology for keeping your home warm.

Cost Effectiveness
While freestanding units and window units are very common throughout the world, it would take a separate unit in each room of the house to create the same level of heat, especially in a large, multi-story home. Running several separate units also totals to a larger amount of energy use, which means you are paying more for individual units than you would for central heating.

Because central heating systems work off a closed, sealed system of circulated air, they run very efficiently. The vents can also be installed low in the ground to propel upward from a low point. Because the physics of air dictate that warm air rises in a cool space, the warm air created in a central heater will rise through the room rather than sitting up at the top of the room. This is ideal for homes with multiple stories or high ceilings.

Modern furnaces are safer due to their sealed combustion chamber while central air systems are heatpump heating systems that are all electric. Also, space heaters are a frequent fire risk because they can overheat or set fire to the flooring or nearby items. Central furnaces do not carry this same risk.

Central heating and air conditioning installation for Canton, GA, homes can be more complex and expensive at first, but the level of comfort these systems provide make it well worth the effort and initial expense. Also, keep in mind that the high efficiency of these systems saves you money in the long term.

Central Heating

Closeup of hand pressing button on digital thermostat

Central heating systems have a primary heating appliance, such as a furnace, typically located in your basement or garage. 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. Depending on your situation, region and needs, you can choose from heating systems running on either gas or oil as fuel, or a hybrid packaged system that can use both fuel types.

How central heating works
Combustion gases are generated by the burners in your furnace and passed through a heat exchanger. Air from your home blows across the heat exchanger to be warmed. It is then blown through a system of ducts to distribute around your home. During warm seasons your heating system works with your central air conditioning. Air is cooled as it’s blown over your air conditioning unit’s cooling coil, often attached to the air circulating fan of the furnace, and then sent through the same air ducts throughout your home.

Why Are Some Rooms in My House Hotter (or Colder) Than Others?

Closeup of hand pressing button on digital thermostat

Have you noticed that some of the rooms in your home are always hotter or colder than others no matter what you set your thermostat to?

First, check for these common problems:

  • Dirty air filter—A dirty filter restricts airflow, not letting your home get enough cool air.
  • Closed vents—Closed vents in rooms can cause them to be hotter than other rooms.
  • Open windows—Your conditioned air can flow out of open windows, leaving uneven temperatures in your home.
  • Air duct issues—If you have any kinked or crushed supply ducts, certain rooms won’t get enough air. Also, leaky ducts cause a host of problems, including uneven temperatures. Here’s how to tell if your ducts are leaking.

If it’s not one of the problems above, the next likely cause is an unbalanced air conditioning and heating system. You’ll need an AC company to balance it.

What is air balancing?
Air balancing is the process of adjusting the amount of cooled and heated air each room in your home gets.

In a perfectly balanced system, every room in the home would reach the same temperature at exactly the same time. A home with very different temperatures in different rooms is said to have an unbalanced system.

Causes of an unbalanced system (and how to fix them)

Many different things can cause your air conditioning and heating system to be unbalanced.

When an air conditioning system is installed, larger ducts and more supply vents are used to get larger volumes of air into the rooms that need it.

Proper duct installation gets your system pretty close to balanced. Dampers are then used to fine tune the airflow and provide even temperatures throughout your house.
Dampers are valves that let you accurately adjust the amount of air going to each room or part of the house. They are installed on the main ducts near the inside unit of the air conditioner (usually in the attic or a closet).

House Always Seem Cold?

Woman with long hair and natural makeup. Fashion model with pretty face. Girl on autumn natural background. Beauty and fashion. Season and fall holiday.

A common complaint from homeowners, and it seems mostly from the ladies of the house, that their house always feels cold. They are freezing all the time. Nothing is worse than to be paying for heat in the winter time, to only feel cold and uncomfortable. After all, that’s why we have furnaces in the winter and air conditioning in the summer. There are many reasons why your home may seem cold all the time, even when the thermostat is set at your comfort level. I will endeavor to address some of these reasons, and also provide viable solutions.

  • Check your windows and doors: Older homes do not have energy efficient windows and doors. Many have single pane windows that allow heat to escape and cold to penetrate. Replace single pane windows with double or triple pane models. They will pay for themselves in no time at all. Windows need to be caulked inside and outside. Doors need to have good seals. Use weather strip around doors to prevent heat loss. A protective clear film can be installed over windows to prevent heat loss. All of these items can be purchased at your home improvement store.
  • Fireplace Damper: All fireplaces have a damper up inside the flue, above the fire box. Make sure it is securely shut to prevent heat loss. If you use your fireplace regularly, then you need to have an airtight glass fireplace doors to keep the air from escaping.
  • Ceiling Fans: As we all know, heat rises, so all that good warm air ends up at the ceiling. Having your ceiling fans turn counterclockwise in the winter will push that air from the ceiling down to the floor, and will do it without a draft. You can run your fans 24/7. It will cost very little to do so, and you will be much more comfortable. You can run them at low or medium speed to get the full benefit. You don’t have to run them on high.
  • Leaking ductwork can be the culprit. Your ductwork is where all that nice warm air travels to each room of your house. If there is a break in the line, or ductwork has come undone, then you will find you are heating your crawl space in the foundation or attic. Have one of our qualified technicians check your ductwork for heat loss. Make sure none of your vents are closed or covered up with boxes, furniture, etc
