What Is the Difference Between AC And HVAC?

Unless you work as a heating and air conditioning professional, understanding the difference between an HVAC and AC unit can be confusing and challenging. Despite these shortcomings, as a homeowner, you might want to know the basic differences between an HVAC and AC, considering that they are one of the most important systems in your home.

What is an HVAC unit?

The term generally stands for heating, ventilation, and air conditioning. It’s a combination of both the heating and cooling components as a whole. Additionally, your HVAC unit will have duct-work and ventilation systems designed to allow moisture escape. While it’s safe to say that all HVAC units do support air conditioning units within the system, not all air conditioning units can be classified as HVAC units.

The heating component of your HVAC system may come in various forms. Some portions feature central heat powered by fuel or electricity. Options using the electric heat pump are mostly preferred for their versatility, allowing the unit to cool and heat your house under one unit.

What is an AC unit?

Also known as air conditioning units, an AC unit is designed to cool the air in your house. We also like to think that an AC unit conditions air regardless of whether it’s hot or cold. There are various types of air conditioners: window units, central air conditioning units, and split or ductless systems.

What is the fundamental difference?

It all boils down to the functionalities between HVAC and AC units. An HVAC unit ventilates, cools, and heats your home all under one unit, while an AC only cools your house. We understand that the average homeowner may fail to get the technical concepts behind the HVAC and AC units’ workability. However, this piece should help you find some footing.

When Should You Replace Your HVAC System?

We get it; HVAC systems aren’t every day or instantaneous purchases. You will probably turn to an HVAC technician for a quick repair if it starts misbehaving. If your HVAC unit breaks down, you will need a lot more convincing for you to replace it. A majority of our clients will only replace a unit if it’s dead beyond salvaging. However, reasons such as maintaining high performance and energy-efficiency are pivotal in pushing you into investing in a new HVAC system even before it breaks down completely. So, when should you replace your HVAC system?


The average lifespan of an HVAC system is anywhere between 10 to 15 years, depending on the maintenance provided over the years. If your system has outlived its expected life expectancy, you probably need to let it rest and replace it. Old systems are notorious for running less efficiently, increasing your energy bills.

Frequent breakdowns

Do you call in your HVAC technician for repairs more frequently than usual? If your HVAC unit breaks down a little too frequently, demanding enormous repair costs, sometimes more than half the price of investing in a new HVAC unit, perhaps it’s time to replace it.

Escalating energy bills

Like most things in life, the older they get, the less efficient they become. HVAC units aren’t any different. You might notice a decline in efficiency in your heating and cooling system as it ages. This reflects on the escalating energy bills. You might want to remedy these economic fluctuations in your home by purchasing a new HVAC unit.

Bizarre sounds

It’s normal for your HVAC unit to operate quietly and smoothly. You can’t ignore unusual noises such as squealing, screeching, or grinding noises. While some of these problems can easily be solved through repairs, you might need to replace the entire system if it becomes too frequent.

If you cannot decide whether to schedule an HVAC repair or replacement service, you might want to talk to us. Call us today at Advanced Air HVAC Medford, Oregon, to speak to a professional HVAC technician. Get the help you need today!

Is It Cheaper to Replace Furnace and AC Together?

If you are in the market to replace either your furnace or your air conditioner, the chances are that you will come out with a better price if you just replace both at the same time. 

Reasons Why You Should Go Ahead and Replace Both

There are several reasons why you will benefit by going ahead and replacing both. These include:

• Lower purchase costs. You may get a deal by purchasing the entire unit. You can even look into financing the entire heating and cooling system. 

• Lower utility costs. If your units are over the age of 10, they will not be as efficient. This could cause strain on your furnace, which will, in turn, raise your heating and cooling bills significantly. 

• Fewer breakdowns. If you have an older AC or furnace, they could be subject to breakdowns. If you find yourself doing more repairs each year, it is time for a replacement. 

• Works better. A new heating and cooling system will work better. Imagine that you only replace your furnace. It works great, but when you go to turn your air conditioning on, it is sluggish and does not cool your home well. If you replace both, you do not have to worry about this. 

Replacing both your furnace and your air conditioning makes sense. It will not help you a bit to just replace your furnace and not your air conditioning system as you could have breakdowns.

It could even cost you more if you have to call the HVAC company out later to fix your broken down air conditioning. Replacing both allows you to have a full functioning unit. 

If you are in the market for a new heating and cooling system, please call Advanced Air today. They will be able to help replace both your air conditioner and your furnace quickly. They can also take a look at your ductwork to make sure that it does not need to be replaced at this time. Having an efficiently running HVAC system can help you to save money and have a home that is at the temperatures that you want.

How Often Should You Replace Your Air Conditioning Unit?

Your air conditioner may be reliable right now, but it won’t last forever. Like any other appliance in your home, it will break down and need to be replaced eventually, and it’s up to you to know when that time has come.

Most air conditioning units will last between 10 and 15 years before they need to be replaced, but that can depend on a few different factors. For example, modern air conditioning units are often built to last a long time, with some lasting as long as 20 years. Many have been built with larger homes in mind, and they can better withstand the stress of cooling a busier and more crowded home than something that was built only a few years earlier. Meanwhile, an older air conditioner may need to be replaced in less than 10 years unless you’ve kept it in top working condition. 

To decide whether or not to replace your air conditioning unit, you need to consider the age of your unit and how well it functions. If your unit is 10 years old but has never needed any repairs beyond a quick tune-up, you could probably go another 5 or 10 years before you need to consider a replacement. 

On the other hand, if your 10-year-old air conditioner has broken down and needed repairs frequently or if it’s contributing to higher utility bills, you might want to start shopping for a new unit. Besides, if you have an older air conditioner that has become obsolete, the parts needed to repair your unit might be all but impossible to find. Your options might be to replace your air conditioner or go without air conditioning. 

The answer to how often you should replace your air conditioning unit is a little more complicated than it seems at first. The easiest answer is to say every 10 to 15 years, but it also depends on different factors. If you find yourself spending more money on upkeep than you would on a new unit, then go ahead and buy a new unit. If you do decide to stick with your current air conditioner for another 5 to 10 years, make sure it’s in good working order so you don’t have to constantly spend money on repairs.

How Long Does a Carrier HVAC System Last?

If you are looking to get a Carrier HVAC system or you already have one, you may be wondering how long it will last. A Carrier HVAC system should last anywhere from 15 to 25 years. However, this can vary depending on several different factors.

 You will want to make sure that you keep up with several different things to ensure the full functionality and long-term life of your heating and air system.

What Can Affect Your HVAC System?

There are several things that can reduce the lifespan of your heating and air-conditioning system. These include:

• Poor maintenance

• Undersized system

• Oversized system 

• Improper installation

• Extreme usage

• Improper usage

• Installation in corrosive environments

The worst thing that can happen with your heating and cooling unit is for it not to be maintained properly. Oversizing or undersizing can also cause breakdowns to your machine.

If you live in a coastal area, the salty air can corrode the outside parts of your system.

How to Ensure the Longevity of Your Unit

You will definitely want to increase the longevity of your Carrier unit. Like any other piece of equipment in your house, proper maintenance and care will ensure that it lasts a long time.

• Yearly maintenance. Preventative maintenance should be done at least once a year. Preferably, you should do it twice a year. Once in the spring and once in the fall. You should have a professional company come out to take a look at your unit and do the maintenance to it.

• Change your air filters. One of the best things you can do to ensure your unit’s longevity is to make sure that you change your air filters. If your unit becomes clogged, it can cause issues with the fan motor and more.

• Sized correctly. You will want to make sure that you have the correctly sized unit in your home. Call your local HVAC company to have them come out to make sure that your Carrier unit is sized properly for your home. Oversized heating and cooling units can come on and off more frequently, which can lead to them breaking down sooner.

In order for your Carrier heating and air conditioning unit to live out 15 to 25 years, you need to make sure that it is properly taken care of. Getting routine maintenance, checking the filters, and ensuring that it is sized correctly will ensure that you do not have any premature breakdowns with your HVAC system.

How Often Should You Replace Your Air Conditioning Unit?

If you’re a homeowner, having your air conditioning unit break down on you is probably the last thing you want to think about. A new unit might be expensive, but so is constantly needing to make repairs on an old AC system. Since part of having central air is knowing when to replace the main unit, here are a few tips that will help you know when that time has come.


The Age of Your AC Unit

The best way to determine if it’s time to replace your AC unit is to consider its age. Most air conditioning units will last between 10 and 15 years, but they tend to require more repairs and become less efficient once they reach 10 years of age. If your AC unit is at least that old, you might want to consider buying a replacement instead of having it repaired. An old AC unit is far more likely to break down sometime after being repaired than a newer model.


Look to Your Utility Bills

One great reason to have an older AC unit replaced is to save money on your utility bills. Higher heating and cooling bills can be caused by any number of things, but one of those things is usually an inefficient AC unit. This is one case where buying a new air conditioning unit will actually save you money in the long run, especially if you do your homework and select a unit that is the proper size for your home.


Check Your Air Quality

It might be tough to gauge the quality of your home’s air, but an increase of dust in the air and on your furniture is still a good indicator that something is wrong with your HVAC system. It might not be related to your air conditioning unit, but if your home is dustier than usual and you have an older unit, it’s probably time for a replacement.


Cooling Inconsistencies

While turning on your AC won’t instantly cool your home, the temperature should at least be consistent once it stabilizes. If you notice that some rooms are cooler or warmer than the rest of your home, you should at least have your AC unit serviced, if not outright replaced.

As much as you might not want to replace your AC unit, there will come a time when it is the best course of action. If you think you’re due for a replacement or you simply need your own unit serviced, contact Advanced Air today.
