Temperatures are rising, days are longer, and summer is right around the corner. Unfortunately, you may also be seeing your cooling bills rise. If you are, these could be signs it is time to consider replacing your current system with a newer model. Newer air conditioning models can better meet your unique cooling needs and save money.

The decision to replace an aging air conditioning system isn’t easy. First, you need to weigh the pros and cons and decide whether it’s the best course of action for your home. Then, depending on the age of your current AC unit, you might need to upgrade sooner than you think.

Breathing in the summer heat can be miserable if you suffer from allergies. In addition, respiratory infections and asthma attacks are on the rise. That might be another reason you’re wondering if it is time to upgrade your HVAC system. So, where does this leave you as an HVAC owner?

Fortunately, you have the power in your hands to create a healthy indoor environment. Your HVAC system is at the core of keeping your home or office comfortable. It provides you with a clean, filtered stream of air to breathe. Plus, it helps keep the temperature just right in your space.

Most people have an HVAC system that they rely on to keep them comfortable year-round. The average lifespan of your AC system is at least ten years with regular maintenance. So once it reaches a certain age, you should start to plan for upgrading or replacing it.

Let’s discuss some signs to help you decide regarding your aging ac equipment. When purchasing a new system for your home or office space, always seek professional advice from an HVAC technician.


Common HVAC System Problems

It’s easy to forget your home is equipped with an HVAC system until it ceases to work properly. Unfortunately, many people wait around for problems with their HVAC systems to arise before considering upgrades or repairs. That’s a big mistake. Instead, you can take a more proactive approach by checking this list of common signs of HVAC issues and problems.


1. Consider the Unit’s Age

Generally, ten years is the maximum time that a heat pump or air conditioner should operate before being replaced. Therefore, the age of your AC system is an important factor to consider when deciding whether or not to replace it. If you have had an annual maintenance contract with a professional company, you should have been alerted when it was time for a replacement based on age and condition.

However, if you don’t have an annual heating or cooling maintenance contract, it’s time to get one. If you have an older unit, you might be bleeding energy and money even if it still works.

If your current system is nearing or past ten years old, replacing the entire system, or at least the outdoor condenser unit, is a good idea. You should also consider upgrading your system if it has required two or more repairs in one year. That’s another indication you are using an older system. Newer models will require less frequent repairs and less energy to maintain a comfortable temperature. Plus, with proper maintenance, they can last longer.


2. Your Energy Bill has Increased

Has your energy cost increased over the months or years? Be especially cautious if you haven’t changed any of your habits in the home. A sudden increase in energy costs often indicates problems with the HVAC system.

Schedule an inspection to know for sure if the system is to blame. For example, it might be time to upgrade if you spend much more than others around you on your utility bills every month.


3. You Always Need to Repair Your Unit

Have you repaired your HVAC system several times in a short period? Then, start thinking about your repair cost over time. Your system should be paying for itself over time, not costing you more.

A system that is functioning won’t require much professional attention. However, if you find that you’re continually calling service professionals to inspect your HVAC system, it’s time for an upgrade. You’ll save more on repairs by buying a new one in the long run. However, it just gets more expensive by continuing to fix the old one. A major breakdown could cost as much as a brand new furnace or air conditioner!


4. Your HVAC System is Noisy

Your system may make some noise when it starts up or shuts down. However, if it’s running noticeably louder than usual, there could be something wrong with internal components like the blower motor or fan belt. You’ll want to have a professional inspect the system and make recommendations on whether the problem can be fixed or if you’re better off replacing it.

Specifically, be looking for banging noises, clanking, squealing, clicking, or rattling. The unit or even the ductwork could be to blame. A certified service technician can inspect your system, including the ducts, to analyze and diagnose the problem.


5. Your HVAC System Doesn’t Perform as Well as It Once Did

You may be running your HVAC system all the time and still not feel comfortable in your home. Perhaps you’re not getting as much cool air as before. You may feel comfortable one minute but then too hot or cold the next. This could also be a sign of ductwork leaks.

There’s a strong chance your HVAC system is to blame. Many homeowners have no idea that their AC unit is too small for their homes. When your air conditioner is too small for your house, it runs constantly and never reaches the temperature you’ve set on the thermostat. This can be frustrating, but it’s also expensive.

A unit that’s too small won’t cool your home effectively and could cost you hundreds of dollars in wasted energy each year. A certified AC tech can tell you what size AC you need based on the square footage of your home. So before committing to a new central air conditioning unit, get all the information you can.


6. You’re Selling Your Home Soon

Selling your house is an excellent reason to be considering upgrading your HVAC system. Nobody wants to worry about spending thousands on upgrades or repairs after purchasing a home. Upgrading your AC unit can dramatically increase the chances of your home selling.

Upgrading your home’s HVAC system before listing your home may increase your property value. However, you don’t want to focus on the cost of replacing or upgrading it. Instead, think about what you’ll get in return.

If you replace the unit with a high-efficiency model, you could see energy savings before moving. Plus, you can also increase your asking price. If you invest in a Lennox unit, you may also be able to market the home as having “green” features. Lennox AC systems are designed to help you reduce your carbon footprint while improving efficiency. Being environmentally friendly could help make your home more appealing to specific buyers.

If you have a nonfunctioning HVAC system, buyers will likely ask for a deep discount on the purchase price or ask you to fix it before moving in. Unfortunately, this can cost you more money and complicate the sale process.


7. It’s Too Humid in Your Home

There should be very little to no humidity inside your home. Excessive humidity is a telltale sign that your equipment is broken, needs a tune-up, or isn’t operating as it should. Depending on your humidity levels, it can also cause mold in your home. If you notice mold, you should also start thinking about air purification. In some cases, a dehumidifier can fix the problem. However, your HVAC system is likely the true source of the problem.

Several factors lead to poor indoor air quality. Humidity is only one of them. If your AC unit isn’t energy-efficient, it impacts your comfort and creates many other problems. If you are struggling with humidity in your home, you have several options to help control the situation, including upgrading your HVAC system. Modern air conditioners are designed for efficiency. Lennox produces the best air conditioners in the industry. They have the highest efficiency standards to serve you and your family for a long time.

Before you start exploring how to upgrade your home’s HVAC system, it’s essential to understand the difference between high humidity and high moisture levels. While these two terms may seem interchangeable, they’re quite different situations.

High humidity means a large amount of water vapor is in the air. It makes you feel sticky and uncomfortable. High moisture levels mean liquid water is abundant on surfaces such as windows or walls. High humidity can lead to high moisture levels if not appropriately addressed. When people refer to humidity issues in their homes, they usually refer to high humidity and high moisture levels.


8. Your Home is Exceptionally Dusty

If you feel yourself digging out the duster more frequently than usual, your HVAC system might be to blame. Your ductwork might also need a thorough cleaning. Dust is one of the most common allergens that affect indoor air quality in the summer season. In addition, one of the most significant signs that it’s time to replace your HVAC system is if there is a lot of dust in your home.

Over time, the filter on your furnace or cooling system gets clogged with dust and other particles. As a result, you will start getting high heating or cooling costs. Or even worse, if your AC is too dirty, it can stop working. Of course, no one wants to deal with that on a hot summer day. So if you’re finding that you need to clean your HVAC system often, it’s probably time to get a new unit before it wears out completely.

When replacing an old system, always go for a high-efficiency air conditioner and follow up with proper maintenance. We also recommend that you practice efficient air conditioner use with a programmable thermostat.

If you’ve noticed any of these issues with your central air system, it’s time to give The Cooling Company a call. We are always standing by to answer your questions.



The average lifespan of an HVAC unit is roughly ten years. These are complex systems that require regular maintenance for greater efficiency. When your current HVAC system can’t keep up with your unique needs, it’s time to consider a new HVAC system. Otherwise, you may spend too much time and money on expensive repairs.

When is a great time to upgrade your system? It is the right time to replace your old HVAC system before it breaks down completely. So you must be able to identify the signs.

Identifying the symptoms of a central air conditioner failure can save you money. While some warning signs may be due to the system’s age, others issues can show up in less time if the system does not get the proper care.

You can control your cooling costs, maintain a comfortable environment, and protect the long-term integrity of your system with regular HVAC maintenance. In addition, it’s easy to extend the life of your system by protecting it from major failures. So after you get your new air conditioning system installed, don’t stop there. Get a seasonal tune-up twice a year by a certified HVAC technician.

A lot goes into deciding whether to get an air conditioner upgrade instead of an AC repair. It can be very confusing for homeowners to determine if the time has come to get a new air conditioner. However, it generally comes down to two things: cost and efficiency. First, you want to choose a unit with good energy efficiency. So pay attention to the seasonal energy efficiency ratio (SEER) rating. You will save on energy consumption when upgrading to a higher SEER rating unit.

The Lennox brand is leading the industry when it comes to efficient HVAC systems with high SEER ratings. In addition, some units come with unique features such as Silent Comfort Technology for quieter operation. At The Cooling Company, we are proudly a Premier Lennox Dealer.

When your system experiences repeated breakdowns or doesn’t yet meet current efficiency standards, it’s probably time to consider replacement options. If that’s the case, don’t worry. You’re not alone in this. Contact The Cooling Company and

discuss this with an expert today. We’ll help you find an energy-efficient system that’s within your budget.
