Air conditioners are a staple of the modern home. They’re something that you might not think about much, but you will definitely notice when it isn’t working properly — especially in the summer months! There’s nothing quite like walking into a cool, air-conditioned home and being rejuvenated from the sweltering heat of the summer sun. In the case of air conditioners, and most HVAC services, the key is preventative maintenance. Don’t wait for your air conditioning unit to go down and deprive yourself of that cool relief. Make sure you know the signs of a faulty air conditioning unit. When you know the signs, you can call your local HVAC services like Gundlach’s Service in Bakersfield for AC repair before your air conditioning unit goes down! 



Squeaking, grinding, banging, or any other noises besides normal air conditioning unit noises are cause for concern. Noises can occur for a number of reasons: a belt came loose, a wheel needs greasing, a component may be broken, or maybe something is inside your unit that shouldn’t be. Whatever it is, make sure to call your local HVAC services for AC repair before the squeaking turns into the silence of a broken air conditioner.

Warm air

Warm air coming out of your vents in the winter months is fantastic, but warm air coming out of your vents in the middle of July? Not so much. When your air conditioning unit is moving warm air throughout your house, it can be a sign of a compressor issue. The first thing we recommend doing at Gundlach’s Service in Bakersfield is checking your thermostat to see if it was accidentally turned up so that the furnace is running. If that’s not the case, then it is a good idea to reach out to a professional AC repair person to check your compressor and get your home back to a comfortable temperature quickly. 

Frequent on and off

Another sign that you likely need AC repair or a new air conditioning unit is when your system frequently cycles on and off. In the summer months, it is normal for your HVAC system to run a little longer to combat the summer heat. But when your system is constantly running with very little time in between the off and on time, that is a sign that your air conditioning unit is working harder than it should to keep your home cool and is likely in need of AC repair.

Your air conditioning unit is older

Air conditioning units age a little bit faster than dogs. Roughly (ruffly) speaking, one year for us is nearly eight years for your air conditioning unit! Which means that after about 10 years, your unit is starting to reach the golden years and is about ready to retire. If you are unsure about whether or not your air conditioning unit is too old and needs replacing, then reach out to your HVAC services in your area. They are experts in the field and will be able to give you a more concrete answer.


Did you know that air conditioning units not only cool your home but that they control the humidity inside as well? If you notice that your home is consistently more humid than normal, it could be an indication that your air conditioning unit is malfunctioning and is need of AC repair. When your home is still very humid even with the HVAC system running, it’s a sign that you either live in Florida or it’s time for HVAC services.

Bad air flow

It’s tough to say exactly how strong the air flow should be coming from your vents. In general, we believe that it should at least be strong enough to rustle your window blinds. Nobody knows your HVAC system better than you, though. So, should you notice that the air flow coming from your vents is significantly weaker than normal, this could be a sign of an obstruction or a problem with the air conditioning unit. We recommend contacting a local HVAC services expert like Gundlach’s Service in Bakersfield who can help you diagnose and quickly resolve your AC repair problem! 

Smelly air

Another sign that could indicate that your air conditioning unit is in need of AC repair is when you smell a musty, earthy smell coming from your vents. This could be evidence of bacterial or mold growth with the air conditioning unit or within the vents in your home. 

A spike in the energy bill

The last sign that our team at Gundlach’s Service recommends keeping an eye out for is a big spike in the energy bill. It is common for your bill to spike in the very cold or very warm months, but you will notice a huge spike if there is a problem with your air conditioning unit. This is because if your unit is damaged and in need of AC repair, it may be working overtime to cool your home to the appropriate temperature, therefore using much more energy.
