What are the signs that your conditioner needs repair?

For many homeowners, the air conditioner is one of the most important appliances in their home. It's crucial for keeping things cool during those hot summer months. But what are some signs that it needs repair? We've compiled a list!

The Unit Is Not Blowing Cool Air

Are you feeling warm or room temperature air when you should be feeling cold and refreshing air? Even if you turn it full blast, you simply do not get any cold air.

Evidently, this is the first sign that you need to call an HVAC professional to take a look at your AC. This might mean that the compressor has broken or maybe that the levels of Freon inside are too low. Please do not attempt to open the unit on your own. The chemicals might be harmful. An expert should be able to tell you exactly what happened. Learn more here.

Low/No Air From Vents

In some situations, your AC is giving out some cool air, but not nearly enough. Therefore, the compressor might not have broken down completely like above, but may be on its way to do so. Call in a specialist as soon as possible!

Thermostat Can Not Reach Set Temperature

If you notice that the actual temperature is much lower or higher than it should be, or if one or more rooms of your house are cold and comfortable while in others the air conditioner seems not to be working at all, there might be something wrong with the thermostat or vents.

Learn more about why your thermostat isn't reaching temperature here.

The AC Is Making Loud Noises

If you hear noises similar to grinding or scraping, the belt could be out of place. So you should call a licensed technician right away before more damage to the AC occurs, which could cost you more money in the end.

Your AC Is Dripping Water

Moisture or leakage of any kind around your system is bad news. You’re in for an air conditioner repair as soon as possible! The leakage can represent two things – water if one of the drain tubes which is supposed to get rid of condensation is blocked or, the worse of all, refrigerant.

This is why you shouldn’t handle this on your own. Please keep in mind that refrigerant is a powerful chemical!

Your AC Is Emitting Foul Smells

For example, if you feel the smell of metal over an open flame – a bit burnt, very sharp, and definitely metallic – the wiring inside could be burning. Call AC repair right now! Do not linger because this issue will not go away on its own.

Another odd smell that tells you something is wrong is a very stale or musty one. Of course, this should put you in the mind of mold inside the unit itself, which now needs to be cleaned.

To ensure your safety, if you notice any of these smells, turn off your AC and call a licensed technician. Do not turn the AC back on so as not to spread any more mold spores throughout the house or burn the wires further.

High Electricity Bills

If you start to notice that you are paying higher energy bills than ever before, you can blame it on a problem with your AC. The simplest way to explain it is that, being broken, the air conditioner uses a lot more energy than it should to keep cooling your house.

Another reason could be the fact that you are using an old and out of date air conditioner that needs to be replaced. Modern air conditioners are much more energy efficient and can actually help save you money on electricity bills.

Please take into account that the average lifespan of an air conditioner unit is around 10 to 12 years, provided you maintain it properly. This means calling an HVAC technician twice a year to check your unit and make sure it’s running properly. It’s the best way of discovering small issues and keeping them from turning into costly problems that could shorten the lifespan of your air conditioner.

AC Unit Keeps Turning On And Off

If your air conditioner keeps turning on and off your AC system is most likely short cycling. This could be due to a variety of reasons, such as problems with your thermostat, dirty air filter or condenser coils, an over sized air conditioner, or a refrigerant leak.

We are here to answer all your AC questions! Check out below what the most common AC concerns are.

Surpassing Expectations.

Slide 1

I was very pleased with the level of service. Kenny has attentions to detail and is able to communicate the issue very well. I learned new things in the process. He is also polite and made sure to wear shoe covers, which not many people in the industry do. I will definitely give him a call again in the future and pass on as a reference to friends and family.

SuperTech did a great job, I had my HVAC go down overnight, and with a newborn it's super important to keep him cool during the summer. Troy came out same day, during the delivery window. He replaced the capacitor and topped off the refrigerant, he explained everything he was doing, was courteous, and obviously very knowledgeable in HVAC tech.

Slide 1

SuperTech seemed very confident they could find the solution and began working through a prepared checklist of items to check. He said he was "100%" sure what the problem was without hesitation. I was skeptical because of my previous experiences. Turns out, he was right in being that confident. We haven't had a problem since. I would definitely use them again for the peace of mind that they can fix a problem.

Your AC Questions!

How much does it cost to repair an AC unit?

Why is my AC running but not cooling?

The AC is running, but you feel like it's not doing anything. Why? It could be that your thermostat was set to "heat" and not "cooling." Your air filter might also need a change or cleaning out. Maybe there are ice on the coils of the unit outside too!Or your AC may be low on freon.

How often should I add R-22 freon to my AC?

Your AC should never need adding R-22 Freon unless there is a leak. It never gets consumed. It is constantly cycles through a sealed system. Learn more about what the ban of R-22 Freon means for your aging AC.

How long will your AC last?

The lifespan of an AC unit depends on how well you care for it. A neglected one might only survive 7-10 years, while a properly maintained one can be expected to live 12 - 15 years!

Should I repair or replace AC?

Repairing an old AC unit can be tricky. If the repair cost is lower than the replacement costs, you may want to get it repaired instead of buying a new one.
