How Do You Know When to Replace an HVAC System?
The cost of purchasing and installing air conditioning systems represents a considerable investment for most people. If they are maintained on a regular basis, they can last quite a few years, but eventually they will begin to fail. Although it may be tempting to nurse the system along for a few years, it can be more expensive in the long run. Routine maintenance slowly gives way to larger and more fundamental repairs. So, what are the warning signs to look out for?
How Long Should a Unit Last?
Many people simply replace their air conditioning systems on a regular basis regardless of their current level of performance. This trend is more prevalent in the business sector, where any downtime can be a real problem for both customers and employees. Many people expect the lifespan for their equipment to be between 10 to 15 years for an air conditioning unit and 15 to 25 years for a heating unit. However, this is a very rough estimate as a number of factors can increase or decrease this number. If the unit is a top of the line model, it will last longer, and if the unit is not serviced regularly, it will fail sooner. As such for many of us it may be a better idea to base a decision on how the unit is functioning rather than when it was purchased.
A Couple of Warning Signs
Luckily there are a couple of warning signs that will provide a good indicator of how healthy the HVAC system is.
Any Excessive or Unusual Noises
If the system starts to make any unusual or loud noises, it can be a sign that the equipment is starting to fail. This indicates that there is wear and tear on the moving parts in the system. This will be causing rattling, rubbing and grinding noises. It is possible to replace the affected parts, but usually if the noise has become noticeable, it is usually too late to fix them cost effectively. The cost of the parts and labour are almost certainly going to be more expensive than obtaining a new system.
A Reduction in the Air Quality
As an HVAC system ages it can start to leak, this will cause dust particles to be introduced into the air. This will reduce the air quality that will be especially noticeable by those with allergies. The heat exchanger may crack and develop holes that could cause carbon monoxide to be introduced into the home. Obviously this is very dangerous, and it is a good idea to install carbon monoxide detectors to facilitate early detection. Any strange smells emanating from the exhaust are a good indication that there is a serious problem. Another sign to look out for is a buildup of soot around the furnace and the vents. A cracked heat exchanger is very dangerous, and it should be replaced immediately by a qualified professional.
