Is It Time to Replace Your A/C Unit? Here Are Key Clues to Look Out For

A good quality air conditioning unit can last for many years without needing a replacement. In effect, it can be quite tough to know when you already need to replace your AC unit, especially since minor problems are almost always fixed by routine maintenance and simple repairs.


However, there would really come a time when routine maintenance or even replacement of its essential parts could no longer extend the life of your old, trusty AC. In this article, we’ll clue you in on some key signs that you already need to book new air conditioning installation services. 


Clue #1: Unit is Over 10 Years Old


Modern AC units are built to last anywhere between 10-20 years, depending on how well it is maintained over time. As such, once your unit hits its 10th service anniversary with your home or commercial space, you should start planning to replace it.


For one, old models periodically get phased out with the rollout of newer models. In effect, you might find it hard to get replacement parts for a decade-old air conditioning unit, making potential repairs difficult and costly, as you’d have to search for rare parts which you might even have to import just to get your hands on.


On top of that, most new models come with better features and are easier to operate. One shining feature that newer models typically have that older models don’t is energy efficiency.


Lastly, old units are prone to frequent breakdowns and might cease to function properly without constant repair work. When you notice that your unit has been malfunctioning quite often, you have to assess whether purchasing a new unit has become more cost-effective than spending money on frequent repairs.


If you decide that purchasing would be the more economical choice, our team at Excelsior Mechanical will be ready to install a new unit for you. 


Clue #2: Energy Bill is Increasing


Did you know that skyrocketing energy bills could be connected to a bad AC unit? The worn-out parts of an old, rickety AC take longer to run efficiently. Hence, they consume more power doing the same work a newer model can do at a fraction of the power consumption. 


Old air conditioning units also function slower. The time a new unit will use to cool your room might be doubled with an old unit. Naturally, the longer the time the AC is on full blast, the higher the bills you’d end up paying. 


Clue #3: Unit is Emitting Bad Odours


You know your AC unit is due for a replacement once it starts to smell like any one of the following:


  • Mold or mildew
  • Leaking gas 
  • Car exhaust 
  • Burning structures
  • Rotten food 


If you notice any of these odours, turn off the AC immediately. Then contact a technician as these odours call for a thorough repair or a new air conditioner installation, depending on the issue at hand, which your technician should also be able to identify. 


Clue #4: Humidity Issues


As mentioned earlier, an old AC unit would tend to have a lot of issues. Humidity control is one of them. An old air conditioner has poor humidity control, leaving humidity levels in your room out of whack. 


Secondly, when dealing with AC units, you have to know the right unit for your space. If your unit is too big or small for your home, it could also affect its functionality in controlling humidity.

 

Clue #5: Unit is Leaking


Just when you thought it couldn't get any worse, you had to put a bucket under your AC. In this case, you might just need air conditioning repair if the only thing leaking is water, but when the refrigerant starts to leak out, too, your AC needs replacing. 


A refrigerant is a liquid or gaseous compound. It plays a significant role in cooling your room but is highly dangerous when it starts to leak. If you notice that the fluid coming out from our AC is not water, turn the unit off immediately and call for professional help.

As the summer winds down in August and you prepare for the cooler months ahead in Saskatoon, Warman, and Martensville, ensuring your home’s hot water tank is operating efficiently is more important than ever. Hot water tanks are the backbone of comfortable living—providing reliable hot showers, clean dishes, and peace of mind. But what should you do when problems arise? Understanding common hot water tank issues—and how to troubleshoot them—can help you avoid cold showers, water damage, or even costly emergency repairs. In this guide, Excelsior Mechanical Ltd breaks down frequent problems, offers troubleshooting tips, and explains when to call your trusted local HVAC experts. No Hot Water? Start Here If you turn on the tap and find only cold water, the issue may be simpler than you think. For electric hot water tanks, begin by checking the circuit breaker to ensure it hasn’t tripped. For gas models, confirm that the pilot light is lit—if not, follow the manufacturer’s guidelines for safe relighting. Sometimes, the thermostat may have been accidentally adjusted, so verify the temperature setting. If your tank is still not producing hot water after these basic checks, a faulty heating element, thermostat, or thermocouple could be the culprit. This is the point at which calling a professional for hot water tank repairs is the safest and most efficient route. Inconsistent or Lukewarm Water? Adjust and Inspect When your hot water is lukewarm instead of piping hot, mineral sediment buildup can be to blame—a common issue during and after the busy summer months. Sediment accumulates at the bottom of the tank and insulates water from the heating element, reducing efficiency. Draining and flushing your tank in August, before fall arrives, is a good maintenance practice. If you notice the problem persists, your tank’s dip tube (which brings cold water to the bottom of the tank to be heated) may be cracked or deteriorated, requiring professional replacement. Low Hot Water Pressure—Check the Valves and Pipes A sudden drop in hot water pressure throughout your home can be concerning. The most common causes in Saskatoon area homes are partially closed shut-off valves, clogged pipes, or mineral scale in the tank and plumbing system. Start by checking and fully opening the hot water shut-off valve near your tank. If that’s not the issue, cleaning aerators in your taps and showerheads can remove minor debris. For persistent pressure drops or signs of corrosion, it’s best to consult with your local plumbing experts at Excelsior Mechanical Ltd for a thorough inspection and solution. Strange Noises from the Hot Water Tank Popping or rumbling sounds coming from your hot water tank are signs that sediment has settled and is interacting with the tank’s heating elements. In August, as water usage shifts with the season, these noises often become more noticeable. Flushing the tank can resolve minor sediment buildups, but recurring noises could indicate that your tank is aging, or that an element is overheating—both of which require professional assessment. Leaking or Pooling Water—Act Immediately If you notice water pooling around your hot water tank, inspect connections, temperature-pressure relief valves, and pipes for visible signs of leakage. Occasionally, leaks stem from loose fittings and can be resolved by tightening connections. However, a leaking tank body—or any significant puddling—signals a serious problem and might require a tank replacement. Prompt action is crucial to prevent water damage and potential mold growth, especially as the weather begins to cool and windows close more frequently. When to Call Your Saskatoon Hot Water Tank Pros While simple issues like tripped breakers, pilot lights, or basic thermostat adjustments can be handled by homeowners, many hot water tank repairs and maintenance steps are best left to professionals. Licensed technicians from Excelsior Mechanical Ltd have the expertise and tools to safely flush tanks, replace faulty components, inspect for efficiency, and ensure compliance with all local codes and safety regulations.
