If your air conditioner is more than 10 years old, if it keeps breaking down, or your power bill keeps increasing year after year, it is time to get a new air conditioner.
With temperatures in the 90's and the family indoors more often, a properly working air conditioner has never been more important; we need cool indoor air to stay comfortable from the Florida heat. So it's no wonder that strange sounds coming from your AC and an increasing temperature inside your home might be unnerving.
Does your AC need to be repaired or will it require a new AC installation? There are two possibilities when your AC stops keeping the house cool: First, there might be a slight malfunction that can be easily repaired. Second, it's possible that your AC has finally given up the ghost and needs to be replaced. Our HVAC technician will tell you after an inspection, but start by investigating the symptoms of your failing AC. Look for these clues to tell you that something is definitely wrong with the AC.
Hold your hand up to a vent. If it's blowing warm air when it should be cooling, that's a problem.
Listen. Is the AC turning itself off and on again in quick sequence? This is a very common indicator that something is wrong.
Your AC is losing energy efficiency and it shows in the bills. Every month the bill keeps going up, sometimes quite dramatically.
You've done the investigation and recognized one or more symptoms of a faulty AC. But does it mean your AC needs to be replaced or repaired? The answer depends on the overall condition of the unit and whether replacement would actually cost less than any needed repairs.
HVAC systems are designed to last about a decade, and sometimes make it two decades before giving out. Some are in place from 30 or more years ago. However, if you have an AC unit that's over 10 years old and is giving you trouble, chances are that it's preparing to fail for good. Older ACs are generally better to replace than repair because of the next point:
Often when an HVAC system is dying, it will experience multiple system failures over time. If you are having to call for more than one repair/maintenance service per year, then your AC is going to continue failing at increasing frequency. It may be better to replace then keep paying for repairs and risking being AC-free at the wrong moment.
As air conditioners age, they become less energy-efficient. They need more power to accomplish less cooling, and very high power consumption to achieve the cooling you need. Check your summer power bills from the last 2-5 years. If it costs more per month this year than last year or previous years, you can ROI a new AC through power bill savings more affordably than using an old inefficient system.
Finally, there are repairs that are more expensive than a new, energy-efficient AC. Coolant leaks, for example, are currently not a cost-effective repair. Common coolants like Freon R22 are quite expensive by the liter, and some have been discontinued so you may need a complete new coolant infusion. This can stack up in price, and often makes a new AC more financially savvy than repairing the old one.
The good news is that most AC troubles can be solved with a lower cost in both time and money. If your AC is relatively new and the symptoms have not been so bad, a quick repair might be all you need to get your AC back on track.
ACs that have never had problems before, or not within your experience of the house, are less likely to be candidates for replacement. If this is the first time your AC has struggled or become noisy, then the problem could easily be a single piece that needs repair, not a system-wide failure. For well-behaved and relatively new ACs, replacement is rarely necessary.
Being attentive can make the difference between a repair and a replacement. Perhaps you noticed the cycle-clicking or rattling sound as soon as it started. Or you took note the moment the AC stopped keeping up with the heat. If you call for HVAC service when you first notice a problem, it won't have time to damage other parts the AC unit.
Trust an inspector. If you're not sure whether to replace or repair your AC, call for service and listen to what the technician has to say. Technicians tend to be straight-forward about what's wrong with the AC and what you'll need to fix it, if you know how to listen. Don't be afraid to ask questions until you understand approximately what's wrong with the AC, your options for repair, and estimated costs of repair vs replacement.
Lastly, consider how bad the symptoms of your AC problems have been. If the house is just a little warm and the newly loud noises are not yet a cacophony, then you may have caught the problem in time. Less-severe symptoms indicate an AC that is struggling, but is not yet broken.
