Many advancements have been made in the field of heating and cooling technology. As features become more advanced and HVAC systems become more complex, their lifespans are constantly evolving, too. So, how long do HVAC systems last in our modern era? When might you need to replace yours? (Hint: if it looks anything like the image above, replacement will be sooner than later!)

If properly maintained, many modern air conditioners and heat pumps generally last between 15 to 20 years. Furnaces generally last within 20 to 30 years, depending on a number of things. Boilers typically last longer than furnaces.

How Long Do HVAC Systems Last? As Long as Circumstances Allow!

There are many factors that can affect the longevity of your system. Consider that the climate conditions when you first purchased your system have significantly changed due to global warming and climate change.

In addition, incorrect sizing, improper installation procedures, and lack of maintenance are also factors that can severely affect the performance of your HVAC unit. These tend to accelerate its wear and tear.

Maintaining Your Heating and Cooling Equipment

To prevent wear and tear from happening, you can do some of the basic maintenance work by yourself. There are simple tasks such as changing the filters or landscaping the outdoors to protect the outdoor unit.

But having a thorough maintenance check is something that’s best left to the professionals. This is best done twice every year on a year-round system like a heat pump package unit, or once per system if you’re using two systems such an air conditioner and a furnace.

The best time to do this is before the start of the heating season (spring) and cooling season (fall). That will allow you to have any problems fixed before the weather changes for the worse.

But really, how long do HVAC systems last? Only as long as they’re well maintained. For this reason, join Neal’s Comfort Club to get quality maintenance services that will make your HVAC equipment last. Our team will inspect your system for signs of damage and fix it right away.

HVAC System Replacement

An aging HVAC system won’t be able to keep your home at a comfortable temperature. As a result, you’ll see increased energy bills.

Humidity in your home can make you very uncomfortable—especially hot summer weather. What’s more, persistent damp can cause health hazards in some cases. A high level of moisture in the air can promote mold growth. To stay comfortable and healthy, you need to know how to lower indoor humidity for cool comfort during summer. How do you reach that ideal indoor humidity range of 30–50 percent?

How to Lower Indoor Humidity During Summer: 5 Simple Methods

1. Ventilate Everywhere

Proper ventilation can help lower humidity. Turn off the air conditioner and open your windows during the cool hours of the day. This will let fresh air circulate through the house. A nice breeze can help bring down latent humidity.

Also, long, hot showers are luxurious—but they produce a huge amount of humidity. Always use the ventilation fan in the bathroom. In addition, open the bathroom window (if practical) to lower the temperature.

In the kitchen, you can also use a fan over the stove. It can help bring down the amount of heat produced during cooking.

Finally, keep your ceiling fans running. Any way you can increase air circulation in the house is one of the best ways how to lower indoor humidity.

2. Use a Dehumidifier

Running a dehumidifier is an excellent way to lower humidity. And, because it’s easier to cool less humid air, this excellent indoor climate control machine can also reduce your AC costs in the long run. A system-wide dehumidifier fits in your air furnace handler. There, it removes moisture as the air passes through. By the time you feel the air, it’s cold and dry—an excellent feeling for summer comfort. And that’s not the only benefit. By using a dehumidifier, you may even reduce the amount of time your AC unit needs to run. And that will save wear and tear, causing you to need fewer air conditioner repairs.

3. Keep All Surfaces Dry

One of the simplest ways to reduce humidity (that few people think of) is to keep all surfaces dry. Wipe down your sink and counter area after washing your dishes. Use a squeegee to take water off your shower walls when you’re done. Also, dry out your sink after you finish brushing your teeth. If the water is left to evaporate, it goes straight into your home’s air. And, as we discussed, moist air can lead to mold formation.

4. Turn the Air Conditioner On

Remember #1 and how we recommended that you open the windows? Well, anyone who knows how to lower indoor humidity knows this: once the air warms up, turn on the AC right away. You should also run it overnight. By doing so, you’ll let the system start removing humidity. As warm air exits and is replaced by cooler air, your home’s humidity will naturally drop. Make sure you change the filter regularly for the best air flow!

Have you ever found yourself wondering, “why is my air conditioner blowing warm air?” After all, a fully functional air conditioner is a must-have for every home in and around Chattanooga. Generally, air conditioners play a significant role in circulating and filtering the air we breathe in. Just a few other benefits of good air conditioning systems include preventing heat-related illness, filtering allergens out of the air, and preventing electronic devices from overheating.

On the other hand, having a faulty AC unit can be quite frustrating. Especially with summer just around the corner. Temperatures are usually unbearable during this season and you need comfortable, cool air more than ever. An air conditioner that blows warm air can give you sleepless nights unless you take immediate action.

Why Is My Air Conditioner Blowing Warm Air?

Well, your air conditioner can start blowing warm air due to various reasons. Let’s look at a few of them.

1. Clogged Filter

When your air conditioner has a good filter, contaminants such as dust and pet hair are filtered out of the air. When the filter becomes clogged by foreign substances, it prevents air from flowing through the system effectively. Your air conditioner may start blowing warm air if not enough air is passing over the condenser coils.

2. Thermostat Problems

The first thing that you should consider doing when your AC system starts blowing warm air is to check the thermostat. From time to time, thermostat components may break. Or, you may have changed the temperature accidentally. Is the thermostat set at the correct temperature and the air is still warm? Just call a professional to diagnose and repair the problem for you.

3. Disconnected or Damaged Wiring

If the wiring isn’t connected properly, your air conditioner will have a hard time functioning as it should. Whether the wires are damaged or simply disconnected, they need repair. Check for exposed or damaged wires. If you spot any, call a professional.

4. Low Refrigerant

Refrigerant is the substance that turns warm air into comfortable cool air. If it’s low, whether from a leak or otherwise, you’ll experience warm air coming from your vents. Your AC repairman will let you know if this is the problem.

Other Common Causes of AC Blowing Warm Air Include:

• Tripped condenser breakers
• Blocked return vent opening
• Blocked/dirty condenser coils
• Power loss to the system’s outdoor unit

An often-overlooked component of HVAC systems, the air filter is crucial to the operation of your heating and cooling system. If you want the system to remain in excellent working order, you should check and change the filter regularly. So, why do you need to change your air filter? Well, one reason is health. If your air filter isn’t working properly, your lungs are probably serving as the air filters. And we all know the potential outcome of that – your family may suffer from respiratory complications.

Including respiratory health, here are 4 reasons you need to change your HVAC air filters.

Why Do You Need to Change Your Air Filter?

1. Create Clean Air

Replacing the air filter of your home’s HVAC system ensures the air remains clean, fresh, and healthy.  This is good for all the people in the home, and particularly kids and the elderly or those suffering from asthma and allergies. Changing the air filters means the HVAC system doesn’t constantly circulate pollen, dust, and other tiny particles in the air. As a bonus, cleaner air means less dusty surfaces.

2. Save Money

Changing air filters saves on operational costs. A dirty filter clogged with debris makes your system expend more energy compared to a new, clean one. You’ll need to pay a higher electricity bill if you continue using a clogged air filter. You can also save money if you …

3. Prevent Damage to the HVAC System

Having a clogged air filter could lead to extensive, preventable damage to your heating and cooling system. If you check the condition of the air filter and replace it when needed, it helps the system function more efficiently for a longer lifespan. The harder it has to work to pull air through the filter, the more wear and tear builds up.

4. Protect the Environment

If you fail to check and change the air filter regularly, it can lead to environmental problems. A dirty air filter means a straining HVAC system, something that uses more energy. That can lead to increased emission of carbon monoxide or greenhouse gases. A simple thing like changing an air filter when it’s necessary can go a long way toward reducing your carbon footprint.

Basically, you should change the air filter every 1 to 3 months depending on how heavily you are using the HVAC system and how quickly the filters are being clogged. This way, the filter – and the entire HVAC system – functions properly and efficiently.

 

As a homeowner, you need to find the best heating and cooling system for your home to make it more comfortable. You may be wondering, “what is a ductless mini-split system?” It’s one of the most popular HVAC system types on the market today, but many homeowners have yet to leverage the benefits it offers.

If you’re in the market for a new HVAC system, keep reading. You’ll get more insight into the incredible ductless mini-split systems. And then you can make an informed choice. This guide explores this type of heating and cooling system.

What is a Ductless Mini-Split System? Overview

Each mini split features two main components: an outdoor compressor/condenser, and an indoor air-handling unit. To connect the two main sections, there is a conduit containing a power cable, refrigerant tubing, suction tubing, and condensation drainage.

How It Works

To cool your home, the unit in each room blows your home’s warm air over cold evaporator coils. The coils contain refrigerant, which draws heat from the air. Then, the outside unit expels the heat into the surrounding air. It is a simple and effective way of cooling and heating your home.

These systems work perfectly in a situation where a window AC unit or baseboard heater can work. But the mini-split has an advantage: it requires minimal drilling in the wall.

You can have multiple indoor air-handling units connected to the outdoor unit to heat and cool the entire house. These systems not only work well for new homes, but are perfect for retrofits and remodels.

Pros of Ductless Mini-Split Systems

1. Easy installation compared to traditional HVAC systems with minimal drilling
2. Multi-purpose function of cooling and heating
3. Built-in zoning allowing you to control the temperature of each room in your home
4. Energy efficiency due to zero leakage through ductwork, unlike central HVAC systems
5. Ideal for home remodels due to easy installation
6. Remote control and customization options
7. Longer lifespan in general
8. Cost savings and other financial benefits, including tax credits, rebates, and other incentives for heat pump upgrades

Cons of Ductless Mini-Split Systems

Ductless mini-split systems carry higher upfront cost than ducted HVAC systems. In addition, you need professional installation services. They can also affect the aesthetic appeal of your indoor space, since you have units in every room. However, you have the option to upgrade the units to the version that is recessed in the ceiling.

How can you keep carbon monoxide from harming your family? It’s a question you need to answer.

When health professionals talk about carbon monoxide (CO), they often refer to it as “the silent killer.” People go to sleep at night, and never realize that a deadly gas is in the air. However, even small doses of CO can cause sickness. For many people, CO-related symptoms are mistaken for other kinds of sickness because they’re so similar.

Because this toxic gas is odorless, tasteless, colorless, and non-irritating, you need to be intentional about detection.

At this point, most homeowners would be tempted to just get a CO monitor, install it, and pat themselves on the back for a job well done. Don’t make that mistake. You do need one. But you should also take additional steps to safeguard your health.

 

How to Keep Carbon Monoxide From Harming Your Family

Keep reading. We’re going to discuss 3 steps you can take to keep carbon monoxide from harming your family.

 

1. Get a High-Sensitivity CO Detector

Carbon monoxide is fast-acting even at low levels. In fact, your heart, lungs, and brain experience permanent harm when you’re exposed to low amounts of CO over an extended time.

However, that’s not the worst part. What many people don’t know is that residential CO monitors wait to sound the alarm until CO has already reached unsafe levels. At that point, who knows how long CO levels have been elevated? Your health may already have been harmed. In story after story of people who survived carbon monoxide poisoning, they were exposed for a long period to “non-deadly” amounts. And some experienced lasting effects.

We’re not writing all this as a scare tactic. If you burn fossil fuels in your home or have an attached garage, CO poisoning is a real health risk.

Here’s a helpful chart of when to expect an off-the-shelf CO alarm to sound:

• 40 PPM – alarm goes off after 10 hours
• 50 PPM – alarm goes off after 8 hours
• 70 PPM – alarm goes off after 1-4 hours
• 150 PPM – alarm goes off after 10-50 minutes
• 400 PPM – alarm goes off after 4-15 minutes

But what if you have long-term exposure at 35 PPM? Your alarm may never sound. And you’ll have to deal with possible symptoms like headache, difficulty thinking, cardiovascular trouble, and others. Over a long period of time, your attention span may shrink, and your health may be permanently compromised.

Install highly-sensitive carbon monoxide monitors. They sound an alarm at levels as low as 12 PPM.

Put them near sleeping areas, in the kitchen, near fireplaces, and in your utility room. They should be located near the ceiling because CO is lighter than air.

 

2. Get a Professional Installer

Sometimes gas appliances break – and need replacement. When the installers are putting your shiny new appliance in, don’t just trust them! Before they touch a thing, ask to look at their permit. And be prepared to deny installation if they’re not properly certified. Your safety depends on proper combustion and venting.

 

3. Get Professional Appliance Testing

Efficient gas appliances keep carbon monoxide out of your air. But how do you know if they’re efficient? You have a technician test them with a combustion analyzer.

A good combustion analyzer tests your gas appliance’s performance in these 3 areas:

1. Efficiency
2. Ventilation
3. Fuel-air mixture

Your heat pump or furnace, water heater, fireplace, stove, and any other gas-fueled appliance should all be tested a minimum of once per year, but ideally twice – right before the temperature change in spring and fall. In addition, have your wood-burning fireplace tested at the same time.

Don’t simply trust that your gas appliances are safe. Find out for sure.
