As temperatures rise, so do energy bills. For most households, the air conditioning system is the biggest contributor. Understanding how your AC system uses energy and what you can do to improve AC efficiency in Dacula, GA will help you keep your home comfortable without breaking the bank. Here’s what homeowners should know about energy consumption, utility bills, and how to save money this season.
If you’re thinking about upgrading your air conditioning system, you’ve likely heard that older refrigerants are being phased out. As of 2025, manufacturers are no longer producing new AC units that use R-410A, a refrigerant that has long been the industry standard. Why? Because it’s time for something better—safer for the environment, more efficient, and just as effective at keeping your home cool.
Let’s take a closer look at the new refrigerants replacing R-410A—specifically R-32 and R-454B—and what they mean for your air conditioning in Lawrenceville, GA.
It might not seem like it yet, but summer is on its way. Are you ready for it? How’s your air conditioner doing? A lot of people wonder about air conditioner repair. Does my AC unit need to be fixed? How often should an air conditioner need repairs? Is it time to think about replacement instead? We’ve got the answers!
Air conditioners make cold air, and if they’re working properly, they’ll make plenty of it. Air conditioners make some noise, although they shouldn’t make any noises that are loud or unexpected, like rattles or bangs.
But one thing an air conditioner definitely shouldn’t make is a smell. If you’ve got AC odors, you need repair. What’s going on? We’ll explain.
Air conditioners often indicate that they’re struggling by the sounds that they make. During normal operation, an air conditioner’s compressor will kick on with a hum, and the fan will whir. If you’re hearing bangs, clattering, whistling, buzzing, grinding, or other surprising sounds, you’ll know right away that you need AC repair.
But there’s something else you should be listening for. It’s not just weird sounds that can mean there’s a problem. It’s when the routine sounds are happening too frequently. If you hear your air conditioner coming on and turning off again every few minutes, something is wrong. Why are these short AC cycles happening? We’ll tell you.
At Wall Heating & Air, we see AC problems every day all summer long. Some of them are extremely common and come up all the time. These are probably things you’ve heard of or can imagine: the motor that powers the blower fan overheats, or a storm-blown tree limb damages a coil and refrigerant leaks out. One way to prevent both common and unusual issues is to schedule routine AC maintenance.
But some AC problems are more unusual. It might never have occurred to you that these things could happen! Thanks to our long experience and extensive training, though, we’re ready for even the strangest AC problems. Here are some odd ones to be aware of.
Oh, no! Your air conditioner stopped working! You must be in serious need of AC repair. Or are you? Could it be that you’ve got a problem you can resolve yourself, without any training or expertise?
True AC problems must be repaired by someone qualified, for many reasons, including safety and making sure you don’t void your warranty. But sometimes, it only seems like there’s an AC problem. How can you tell the difference? Before you call for air conditioner repair, go through this handy AC troubleshooting checklist. Your problem could be resolved in mere minutes.
We often use sight-related phrases in English. “See you later!” “Watch out!” But not everything is actually visual. If we say, “Here are some air conditioner problems to watch for,” or “Look out for these signs that your AC needs repair,” we wouldn’t be pointing you in the right direction. In fact, the first sign of an air conditioner problem is usually a noise. Here are some AC noises you shouldn’t ignore you don’t want to hear your AC making. These noises can come from different units within the HVAC system, such as the outdoor or indoor units. It’s important to maintain proper air flow around the outdoor AC unit by clearing debris and ensuring nothing blocks air circulation, as this helps prevent issues and keeps your system running efficiently. For example, a rattling or buzzing sound may indicate an issue with the fan motor or blower motor, both of which should be inspected for proper operation. Here are some sounds you don’t want to hear your AC making.
Having your old air conditioner replaced is quite the process. First, you have to determine that it’s not worth repairing any longer. Then, you have to decide what sort of system to replace it with and select the specific model. Finally, you must make an appointment to have that system professionally installed.
Done all that? Great! But you’re not finished yet.
The appointment itself can be a bit of a mystery to homeowners who haven’t been through it before, or to folks whose last experience with AC installation was twelve or more years ago. What should you expect? How long will it take? And what can you do to prepare your home for your air conditioning installation? We’ll tell you everything.
As air conditioning season rolls around again, and you need to start running your AC unit, don’t forget to keep an eye and an ear out in case of any problems that might require repair. Often, when an air conditioner first encounters a problem, there will be small but noticeable symptoms. Strange sounds are often an early sign. But homeowners don’t always get repairs right away.
If you think a problem is small, you might not feel that it’s very urgent to have it repaired. But it’s all too easy for a small AC issue to quickly develop into a much bigger one that causes greater inconvenience and is more costly to repair. Let us illustrate for you just how much prompt AC repair can help save you from major hassles and help you to save money.
