How heat pumps work, and why you should consider one for your home

Heat pumps are increasing in popularity here in southwestern Mississippi, and there’s a reason for that: these versatile systems are capable of both cooling and heating your home, are energy-efficient, and are perfect for our mild winter climate here in McComb. In this blog, we’ll review how heat pumps work, and why you should consider one for your home.

How heat pumps work

Unlike air conditioners and furnaces that cool or heat air, heat pumps operate by extracting heat from air and moving it.

Where the heat is moved to depends on the season: in the summer, the heat pump draws the heat out of your home’s air and moves it outside, cooling the inside of your home. In the winter, this is reversed, and the heat pump pulls warmth out of outside air and moves it inside your home to make your family comfortable.

This process is accomplished with refrigerant, which absorbs heat and releases heat when it reaches a condenser. This refrigerant travels in an insulated line between an outside unit and your home.

It’s just physics, really. What’s more, you currently have a heat pump system in your home, and you probably didn’t even know it. Your refrigerator keeps your food cold using the same technology, removing heat from the interior of the fridge and releasing it outside of the fridge.

In fact, most air conditioners use the same process at heat pumps. Your home’s air conditioner is also extracting warm air from your home and putting it outside. It’s just not reversible for winter heating use.

What are the benefits of heat pumps?

Heat pumps have several advantages over traditional air conditioners and furnaces. Let’s review them:

One System

Heat pumps are capable of providing both cooling and heating and reverse between seasons, which means you only need one system, not two. That’s one less system to buy, maintain, repair, and eventually replace. Over the long haul, that can represent a huge cost savings.


Heat pumps use energy to move heat from one location to another. This is far more energy-efficient than the way furnaces and air conditioners operate, and you’ll see the savings on your monthly energy bills.

Perfect for Mississippi

The one big downside about heat pumps is that they’re not suited for true cold-weather winter climates, as they can’t provide quite the warming power of a furnace. However, here in McComb and southwestern Mississippi, our mild winters make a heat pump a great option for your home.

Heat pump options

At Comfort Air, we install a wide variety of Carrier heat pumps, including some that have advanced features and options. Here are a few of them:

  • Variable Speed: Just like with air conditioners, a variable-speed heat pump can adjust its operating speed to maximize comfort and energy savings. Enabled with this technology, the Carrier Infinity 20 Heat Pump With Greenspeed Intelligence is considered one of the best systems on the market today.
  • Upgrade In Steps: For many of Carrier’s heat pumps, the indoor component is universal, allowing you to replace the outdoor unit but keep the indoor setup the same. This is true for the Carrier Infinity 18VS Heat Pump.

Here are the 5 signs that you need a replacement furnace for your home

If your furnace could talk, chances are it would tell you when it was about to breakdown, or needed to be replaced with a newer model. Unfortunately, your heating system can’t talk. However, there are signs that you need a replacement furnace if you know what to look for, listen for, and watch for.

In this blog, we’ll review the signs that you need a new furnace. If you’re experiencing any of these problems, contact Comfort Air for a free in-home estimate on furnace installation.

Five signs that you need a replacement furnace in your home

If your heating system is getting up there in age, it might be time for a replacement furnace. However, what are the signs that your system is on its last legs? Let’s review the five signs that you need a replacement furnace in your home:

#1. Your energy bills have skyrocketed

As the years go by, your furnace needs more energy to generate heat, which can lead to a spike in your energy bills. In other words, you will be paying more for less heat if the furnace is not replaced or repaired.

There comes a time in every furnace’s lifespan when heating repair no longer makes sense from a financial or comfort perspective. It’s time to replace the system. When that day comes, you should really speak to the team here at Comfort Air. We can help you find an energy-efficient heating system that will save you on your bills for years to come.

#2. Your heat exchanger is damaged

The heat exchanger is the component in the furnace that actually generates the heat. Over time, the constant expansion and contraction of the metal due to heat can cause the exchanger to crack. 

In many cases, the cost of replacing the heat exchanger is so high that it doesn’t make sense to just replace it. In fact—unless your furnace is brand-new or covered under manufacturer’s warranties—a new furnace might be the better choice, since you’ll get a boost in energy-efficiency and a fresh slate.

There is no scenario in which you should just leave a cracked heat exchanger as-is. In some cases, a cracked heat exchanger can emit dangerous gases like carbon monoxide. For your safety and the safety of your home, please call Comfort Air if you suspect your heat exchanger has a problem.

#3. Your furnace requires frequent repairs

This is known as the “money-pit” furnace. If your furnace needs repairs every winter, wouldn’t you save money by just biting the bullet and upgrading to a new system? We think so!

A good way to make this decision is to do some back-of-the-envelope math. Think: how much have you paid in furnace repairs over the past two winters? If the answer is over $100, it might be a good idea to think about a new system.

#4. Your furnace is making strange noises

If your furnace makes rattling or popping sounds when you turn it on, there is something wrong with it. It’s one of the most common signs of age, and it’s often the death throes of an old furnace.

If the blower also turns on and off on its own, or blows cold air along with making strange noises, you need a new furnace—pronto. Call Comfort. Our team can help you diagnose the issue and determine what your next steps need to be.

#5. You have a dry or dusty home

Your furnace does more than keep your home warm—it keeps the air clean as well. If your home gets dusty quickly or the air is dry, chances are your old unit needs to be replaced. Dry air can lead to sinus issues. Those sniffles might not be the beginnings of a cold.

Of course, you can best ensure that your furnace or heat pump is clean with an annual furnace tune-up from our team.

Here are the five benefits of fall heat pump maintenance

It’s autumn here in southwest Mississippi. In addition to pumpkin spice lattes, cooler weather is on the way. Is your heat pump ready? In this blog post, we’ll review the five benefits of fall heat pump maintenance, and why you should call Comfort Air for tune-up service.

If your home has a heat pump, it’s important to have a professional HVAC technician take a look at it before you start using it this winter. After the long summer, we need to make sure everything is still working right.

HVAC Tune Up McCombReasons to book your fall heat pump maintenance with Comfort Air

Here are just five of the reasons you should call Comfort Air for a professional heat pump tune-up here in McComb and surrounding areas of southwestern Mississippi.

1. Your system has been working all summer

Unlike traditional air conditioners or furnaces, heat pumps are in use all year long. This means that your heat pump has been working hard to keep your home cool this summer. Before you ask it to keep your home warm this winter, get a tune-up.

With heat pump maintenance, we’ll be able to address any problems or faults that may have developed over the summer. We’ll also be able to ensure that you’re getting optimal performance in the colder months ahead.

2. Increase your system’s lifespan

Regular maintenance and upkeep can lead to a longer heat pump lifespan. Over time, the parts with a heat pump begin to experience normal wear-and-tear. Without regular service and attention, these parts are at risk to break—causing a breakdown and possibly leading you to need a new system after a shorter amount of time than otherwise.

In contrast, regular heat pump maintenance ensures that such parts are cared for and able to last longer. During a Comfort Air maintenance visit, our professional NATE-certified technician will lubricate moving parts, clean the heat pump, and inspect the rest.

The result? Less wear-and-tear this winter—and a longer life for years to come.

3. Make sure you’re getting energy-efficient performance

Regular maintenance will also ensure high-efficiency heat pump performance. This helps you keep your electric bills down during the winter months. In fact, with regular biannual maintenance on your heat pump, you can have an energy-efficient winter and summer with your system, all while avoiding the cost and headache of breakdowns.

4. Lower the risk of a heat pump breakdown

Another great benefit of regular maintenance is that it reduces the risk of emergency breakdowns. That’s because the parts of your heat pump have been checked out and any potential issues have been fixed—all before you turn on the system for the year.

5. Maintain your system warranty

Most heat pumps come with a manufacturer’s warranty, designed to address any problems with the system and give you peace of mind. Sounds great, right? But, look closely: many warranties have the fine print that heat pump maintenance from a professional HVAC company is required to keep the policy intact.

If you want to keep your warranty around (and who wouldn’t?), schedule a tune-up with our team.

Call Comfort Air for tune-ups and service!

In all reality, your heat pump should get two checkups every year: one in the spring, and one in the fall. If you have yet to have your heat pump looked at by the professional technicians at Comfort Air, don’t wait another day! Give us a call at (601) 684-2072 or contact us online.

Air duct cleaning: Why does it matter for my home’s comfort?

Pictured: It's important to schedule air duct cleaning for residential ductwork like this vent.

In many ways, your home’s air ducts are the least visible part of your home. That’s why, for many homeowners, the idea of air duct cleaning often falls by the wayside. There are often more-visible home maintenance projects to take care of, after all.

In this blog post, we’ll share why having a professional clean your home’s air ducts is not an optional part of home maintenance. In fact, there are many benefits to clean ductwork!

If you’re ready to schedule your air duct cleaning, give the local team at Comfort Air a call at (601) 684-2072 or contact our team online

The case for regular air duct cleaning

Both the Energy Protection Agency (EPA) and the National Air Duct Cleaners Association (NADCA) recommend the regular cleaning of residential air ducts. According to the NADCA, the air ducts must be cleaned once every 3-5 years. However, if there’s a member of your household with allergies, you should consider having Comfort Air clean them annually.

A professional cleaning will ensure that your air ducts are free of mold, mildew, dust, pollutants, and other contaminants.

What is in my air ducts?

Dust accumulates in your air ducts over time. Mold and mildew form when there is moisture inside the ducts. Also, if your house has been renovated recently, it’s necessary to have your air ducts cleaned. This is particularly important in case the house remodeling project involved lead paint or asbestos removal. Being exposed to lead or asbestos can lead to fatal lung disease.

It’s essential that you have the ducts cleaned by a professional technician after such home renovation projects.

What kind of impact can this have?

If you don’t have a professional clean your air ducts on a regular basis, it can result in worsening home air quality. People who suffer from allergies will be affected the most by dirty air ducts. Plus, by having our HVAC technicians inspect and clean your ducts, you will not only protect your household from dirt, dust, and other airborne pathogens, but also cut your energy bills.

There are energy-efficiency benefits, too?

Yes. Cleaning your HVAC air ducts can provide year-round, long-term energy-efficiency benefits. A study conducted by the American Society of Heating, Refrigeration, and Air Conditioning Engineers has found that cleaning out dirty air ducts can help reduce your energy usage by as much as 40 percent! Over the course of a year, that adds up to big savings.

Call Comfort Air for your air duct cleaning in McComb and southwest Mississippi

Make sure you contact an experienced technician for air duct cleaning. You will end up paying more if you contact a cheap and inexperienced technician to clean the HVAC ducts. Not following proper procedures in cleaning the ducts can result in inadequate cleaning. It can also damage the ducts that will force cool air out of the house.

Ductless air conditioning: 5 reasons for having ductless AC in your home


Ductless air conditioning systems are becoming more and more popular among homeowners here in McComb, Mississippi. There are several benefits that ductless air conditioning systems provide, which give them an edge over traditional central air conditioning systems. In this blog post, we’ll review what they are.

To learn more about ductless AC systems, contact our team here at Comfort Air.

Ductless air conditioning systems, also known split systems, provide homeowners with flexible air conditioning options. Unlike traditional air conditioning systems that are tied to extensive ductwork, ductless air conditioners are typically wall-mounted in the room.

This means you can control the comfort for each room of your home, independently of one another. This saves you money and offers incredible convenience.

#2. Installation is easy for the Comfort Air team

If you move to a small apartment—or an older home without ductwork—where it is difficult to install a conventional air conditioner or window units, then ductless air conditioning system is the best bet. All you have to do is to mount the indoor unit on the wall and provide it with an electric supply.

The outdoor or condenser unit can be mounted on the exterior side of the wall of the building or can be placed anywhere outside.

#3. They’re energy-efficient

Since the technology behind ductless air conditioning system is relatively newer than the technology of central air or window units, they’re designed to consume less energy. Most of the latest ductless air conditioning systems are coming with inverter technology, which can cut the electricity consumption by 40%.

The energy-efficiency of ductless air conditioning systems is also due to the fact that they generate conditioned air directly in the room it’s needed in, preventing the loss of cooled or warm air through the ducts.

With the reduced consumption of electricity, you can save a considerable amount of money on your utility bills.

#4. No ducts means healthier air

Maintaining healthy and clean air with central air conditioning is a difficult job because you have to make sure that your air ducts are getting regular cleaning service. Even this practice can’t ensure that your indoor air will be free of dust and other allergens.

With a ductless air conditioning systems, your indoor air becomes free of the pollutants that can seep in your environment from ducts. Other than that, most ductless systems come with multilayer filtration, which makes sure that the indoor air is clear of bacteria, pollen, dust and other pollutants.

Their efficient dehumidification capabilities also help make your indoor environment healthier and cleaner.

#5. They’re far quieter than standard AC units

Ductless air conditioners have fewer moving parts and hence generate less noise.
