Your coolant lines and connections are rusted.

Corrosion is a sign that you need to replace your coolant lines and connections. Rust is a clear indication that corrosion has begun, and it’s important to understand the effects of corrosion before you decide whether or not your air conditioner needs to be tuned up this summer. If rust has started forming on your AC’s cooling system, it can lead to leaks in the lines as well as damage inside your home when water pours out onto floors and walls. These leaks can cause significant damage during an outage or when there are high winds outside; if left unchecked, they could eventually lead to permanent damage in your HVAC system as well as expensive repairs on both ends!

It’s also important for homeowners with pets or young children who may accidentally ingest any harmful substances found in their home’s air conditioning system such as coolant fluid or anti-freeze because these chemicals are potentially poisonous if swallowed by small children or animals (such as dogs). Finally – did we mention how expensive it would be if no one replaced an old unit?

Your air conditioner is dirty.

Your air conditioner should be cleaned every year. It’s a good idea to schedule this cleaning before the summer starts, as it can help extend the life of your unit and keep it running smoothly all season long. Dirt, dust and other particles can build up in your air conditioning system over time and cause it to work harder than necessary when cooling your home.

This means that if you start cleaning now, you’ll have time for everything else on your summer-cleaning checklist while still getting an early jump on fall. If you’re worried about making sure that there aren’t any problems with your AC before school starts back up again (which is always something worth being concerned about), then do yourself a favor by taking care of this task first thing!

Know the signs that it’s time to have your air conditioner looked at by a professional technician

There are several signs that it may be time to have your air conditioner looked at by a professional technician.

• Your air conditioner isn’t cooling the house as effectively as it used to, even though you feel like the temperature is cooler in your house. This could be because of poor insulation or leaks around your HVAC system.
• The air coming out of your vents feels warm rather than cold, even though the thermostat indicates it should be cool. This could mean that there’s a problem with your wiring or ductwork that has caused an electrical short or leak (which can also lead to mold growth).
• Your unit is blowing hot air rather than cool—or vice versa—despite being set on “cool” mode and having no visible defects in either its fan blades or coils. This usually indicates a problem with its mechanical parts (for example: dirty coils) or electronic components (such as faulty sensors).

Conclusion

If your air conditioner is struggling and you want to know whether you should repair or replace it, we recommend scheduling a consultation with an HVAC professional. They will be able to inspect your unit and advise you on the best course of action for your situation.
