If you are still using your aging HVAC unit, it may work just fine, but you are probably spending more on energy bills than you need to. In terms of energy savings, today’s newer models are much more efficient.
When you have had your current HVAC unit for about ten years, it may be time to think about replacing it; most experts will tell you that 10 to 15 years is the average life expectancy of the typical HVAC unit. However, you may want to have a technician look at your older unit if it still seems to be doing the job, as with proper maintenance, it is possible for an HVAC unit to last up to 20 years.
Whether it would make more sense just to buy a new unit, or keep using your current HVAC system, an experienced technician should be able to tell you. Troubleshooting these common HVAC problems can also help you make that decision.
Watch Those Energy Bills
A good technician should be able to advise you on what the SEER rating of your current system is. An HVAC unit is more efficient if it has a higher SEER rating, and comparing an older and newer system can help.
If your older system isn’t being properly maintained, it will become less efficient and won’t work to its full potential. This actual efficiency can also help you decide whether keeping your old unit makes sense.
You’ll probably notice higher energy bills if your air conditioning unit’s efficiency decreases. But it may be time to upgrade to a new HVAC system if you notice that every month you have big spikes in your energy bill prices.
How Often Repairs Are Carried Out
It can be tedious and costly trying to maintain an older unit, aside from the fact that it probably costs you more. Keep in mind that a repair every now and then is only to be expected, and it comes with owning an air conditioner.
But nobody wants the expense of having to pay for major repairs every few weeks or few months when it’s hot outside, and you really need your HVAC to work. Constant repairs should be a clue that it’s probably time to replace your system with a new unit, and of course, it gets expensive calling the technician every few weeks.
It’s time to spend money on a new unit that will work more efficiently, rather than wasting money on your older unit, if you are spending more time fixing problems with your HVAC system than you would like.
Your Current Unit and R22 Needs
Freon or R22 refrigerant costs anything from $40 per pound to over $175 per pound, and if you have a coolant leak and are constantly topping it up, it can be costly. It can actually cost you between $550 and $1000 for the cost of the service call and the R22 needed to fix the leak temporarily.
The compressor on your unit will probably die if you have a constant leak, and that can cost $2000 to fix. Again, it simply makes sense to spend that same amount on a newer low-end HVAC system that will last you at least ten years.
