HVAC Replacement: Read on to learn common signs you need a new HVAC system.


Is it time to replace your air conditioning or heating system? How do you know that? Summer is approaching, which means your air conditioning system will be working overtime. Since air conditioning systems are among the most significant investments we make in our homes, you naturally want to get the most out of yours. Even if you keep your HVAC system properly maintained and clean and change your filter on a regular basis, it will eventually need to be replaced.
An increase in energy expenses and poor indoor air quality might be a result of older or broken HVAC systems (IAQ). However, most recent HVAC systems are up to 60% more efficient than older models, sparing you money over time. While setting up a new HVAC system is a great (but expensive) investment, usually people will only do it after their old one breaks down. Would that, however, be a smart option? Or are there indicators to check for that indicate it’s time to replace it?

Signs that Your HVAC System Needs to be Replaced

  • Your System is Greater than 10 Years Old

Do you know when your air conditioning system was installed? Air conditioning systems should be updated every 10-15 years, as per the Department of Energy. The basic components of any HVAC system, while durable, will start to fail after about 10 years (depending on how often they’re used and how well they’re maintained, of course). In addition, systems older than ten years employ a type of Freon (R-22) which 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 minimise your carbon footprint on the environment.

  • Repairs cost more than half as much as a new system.

As an air conditioner ages, you may find yourself paying for regular maintenance and, eventually, the replacement of some of the essential components. When this happens, it’s time to evaluate whether or not replacing parts will save you money over time. It’s time to “out with the old and in with the new” if the repair charges are more than half the cost of a new system. Buying a new system is a wise investment that will save you money overall while also lowering your immediate energy expenditures.

  • Your energy bills continue to rise.

As the seasons change, you should expect rises and decreases in your energy costs, but each month should be pretty consistent compared to the previous year. It’s a sign that your HVAC system needs to be serviced and possibly replaced if you have unusually high energy bills in a month when it’s not expected. The older the system gets, the less efficient it becomes. Regular maintenance (particularly monthly air filter changes) will extend the life of your HVAC system and ensure that it runs as efficiently as possible. However, you will eventually need to switch to a newer machine. The best part is that replacing your air conditioner can save you up to 20% on your total energy expenditures. Many customers discover that their new air conditioner has paid for itself in a surprisingly short period of time!

  • Your house is either a little too hot or a little too cold all of the time.

An ageing HVAC system will struggle to maintain a steady temperature in your home. It could be a maintenance issue (e.g., a broken or inaccurate thermostat, low fluid levels, fractured ducts, clogged filters, etc. ), but temperature discrepancies usually indicate that your AC system is not robust enough or that the duct work is not correctly fitted. Keeping an HVAC system that isn’t running properly and efficiently would end in an unpleasant home setting and much costlier energy bills in any case.

  • You’ve noticed an increase in dust in your home.

Your HVAC system is also responsible for optimum ventilation in your home, in addition to providing you with cooled or heated air. The system should enhance your home’s IAQ (indoor air quality) by eliminating dust, dander, dirt, and other particles and controlling humidity when it’s working properly. If you’ve been noticing a sudden rise in the quantity of dust in your home, it could be an indication that your ac unit isn’t working that great.

  • Odd Sounds & Strange Smells

If your HVAC system emits a strange odour, it could simply be dust smoldering off; but, it could also be something even more serious, like melted wiring or mould in the ducts. If the odour is more alarming, switch off your system straight away and have it inspected. Also, a well-functioning HVAC system should be reasonably quiet as well. If you hear grinding or screeching noises, this is also a warning that you should have your system inspected right away.

  • You have a problem with the quality of your indoor air.

When it comes to indoor air quality in your home, especially during the summer, your air conditioner is the most important aspect. If you see mould, fungus, dust, or odd humidity levels, your air conditioning unit may be damaged, and all of these are symptoms that your system needs to be replaced. Always keep in mind that an NIOSH (National Institute for Occupational Safety and Health) study found that poor ventilation was responsible for almost half (52%) of Sick Building Syndrome cases!
