Signs That Say It Is Time to Replace Your HVAC System

Posted February 6, 2022 by in Home

How frequently do you check your HVAC system? It’s barely a blip on the radar for most homeowners until it breaks down, leaving you sweating buckets in the summer, and shivering in the winter.

One of the most significant expenditures you can make in your house is an HVAC system. While it’s understandable that you want to keep it working for as long as possible, it’s also critical to recognize when it’s time for an upgrade.

Increased energy expenses and poor indoor air quality might be the outcome of improperly maintained HVAC systems.  What’s the good news? Most newer HVAC systems are up to 60% more efficient than older models, saving you money in the long term. While installing a new HVAC system is a great investment, most homeowners will only do it after their old one breaks down. But there are also the signs that indicate it’s time to replace it.

1. Your Unit is More Than Ten Years Old

Do you know when your air conditioning system was installed? Air conditioning systems should be updated every 10-15 years. The basic components of any HVAC system will start to fail after about 10 years (depending on how often they’re used and how well they’re maintained). In addition, systems older than ten years employ a type of Freon (R-22) that is not only obsolete but also exceedingly damaging to the environment.

When you replace your old unit with a modern one, you will not only save money on your energy bills, but you will also be helping to minimize your carbon footprint on the environment.

2. Increasing Energy Bills

If you discover that your monthly heating/cooling bills are steadily rising although nothing in your daily routine has changed, it’s time to have your HVAC system inspected. As the seasons change, it’s natural for your energy expenses to rise, but they should still be comparable to the prior year.  The cause of high energy expenditures is frequently a failing HVAC system.

Regular maintenance (particularly monthly air filter replacement) will extend the life of your HVAC system and ensure that it runs as efficiently as possible.

3. Lots of Repairs

Many of the components in an HVAC system can be repaired or replaced. However, all HVAC systems will ultimately wear out and need to be replaced.

When a compressor, motor, or coil breaks down, replacing it is significantly more cost-effective than fixing it. Parts and labour for repairing these critical components of your system are both expensive and time-consuming. If you received repair bills that are higher than you imagined, consider spending the money on a replacement. 

A new HVAC system will not only help you maximize your home improvement budget but will also keep your home comfy.

4. It Feels Hotter Inside

Is it possible that it isn’t just you? If you notice that your home is becoming too hot, your HVAC system may need to be replaced. An older system may struggle to provide adequate cooling.

This will result in the sweltering heat. One room may be cooler than the others. This can raise the humidity level during the summer months. This is why you must replace the old unit with a new energy-saving unit.

5. The Unit Is Making Loud Noises

It may be an issue of loose parts or a component that has to be replaced if your HVAC system makes noise while functioning. But when you find nothing than pay attention to the sounds listed below:-

  • The blower is making a louder humming noise.
  • The outdoor unit is becoming increasingly noisy.
  • The furnace is groaning and banging 
  • Noise before the air conditioner starts up

A loose part or a part that has to be changed could be the source of some of these noises. Other issues could be caused by issues with fans, motors, blowers, and other moving parts. However, if the strange noises persist after repair, it’s probably time to replace your system.

6. Poor or Weak Airflow

If you turn on your AC unit for the first time this spring and observe that the airflow from the AC return vents is hardly pushing out cool air, your system may be failing. A clogged air filter could be the source of the problem (air filters require regular replacements). A malfunctioning motor, blower fan, or even a more serious problem could cause a lack of airflow. In the end, if your HVAC system is not operating at peak efficiency, you can expect higher energy expenditures.

A cooling system that is working harder than it should meet average output is more stressful on the unit (leading to higher repair costs) and costs more in increased electricity bills.

7. You Have Uneven Temperatures Throughout Your Home

Your kitchen is freezing, yet as soon as you walk into the living room, you start sweating. Why is it that your HVAC system is unable to keep a constant temperature throughout the building?

While this can be a problem of faulty ductwork but if everything seems fine after checking the ductwork and the problem persists, it’s time for the replacement of your unit. 

8. Foul Odors

If you notice bad odors emanating from your HVAC system, it’s not only bothersome; it could also be a sign of a larger issue with your equipment. Mold or mildew growing in the ventilation ducts could cause musty odors coming from your AC vents. Skilled duct cleaning may be able to eliminate the microbial that is creating the odor.

Burning metal or melting plastic odors are indications of a significant HVAC problem. These odors could suggest burned-out wiring or motor installation. Turn off your air conditioner right away and call an expert to assess the extent of the damage.

9. Frequent or Short Cycling

It is natural for an HVAC system to turn on and off to maintain a pleasant temperature in your house. Short-cycling of air conditioners, on the other hand, is unusual. Short-cycling occurs when your HVAC system shuts down before completing a cycle. While one reason for short-cycling could be that your HVAC system is too big for your home, another reason could lead to expensive repairs.

Short cycling is a sign that something is causing your system to work harder than it should. It could be because of a clogged air filter or a coolant refill, or it could be that your HVAC compressor has failed. If the compressor has failed then it is best to replace your AC unit.
