Your AC has one job – to keep you cool. If your air conditioner isn’t doing its job, then you have a problem. The issue could be something minor, or it could be more significant. Find out why your AC isn’t cooling your home and call a Moore air conditioning specialist to fix your HVAC system.
Thermostat Isn’t Set Properly
If you’re lucky, your AC isn’t cooling for a simple reason. Your thermostat might not be set properly. There’s a switch on it that puts your system in fan mode. When it’s in this mode, your system will run the fan continuously. Even when your compressor isn’t running, the fan will be on. This makes it seem as if warm air is coming from your AC.
To find out if this is the source of your cooling troubles, check your thermostat. If it’s in fan mode, switch it back to auto. The fan will only operate when the compressor is on. As a result, the air will always blow cool, and you’ll save money on your energy bill. There’s usually no need to run your fan at all times.
If you have someone in your home who has allergies, you may want to run your fan at all times. Just keep in mind that your system won’t always blow cold air. When you feel warm air, you don’t need to rush to call an HVAC technician.
There could be another easy fix to your AC problems. If you have a dirty filter, the system won’t be able to blow out much air. The limited airflow keeps your home from cooling.
Over time, your HVAC filter collects particles that keep your system from working properly. To prevent this from happening, you should change out your filters every three months. If your AC seems to warm, check your filter. You may need to replace your filter or restore your cold air.
This is an easy fix that you can do on your own. However, you can also hire a Moore heating and air specialist for routine maintenance. When they come, they’ll check and change out your filters. If you have a reusable filter, they will clean it.
Without refrigerant, your air conditioner won’t work. Refrigerant is responsible for a pressure shift that causes cold air to come from your HVAC system. For that reason, one possible cause of your warm air is low refrigerant.
When refrigerant is low, AC will not cool your home the way it should. The air might feel warm, or your AC might constantly run. At times, low refrigerant causes your evaporator coil to freeze. This keeps the system from entering a cooling cycle.
Although your system could have low refrigerant because of years of AC use, the issue could be due to a leak in your system. A refrigerant leak isn’t just bad for your AC; it’s also very hazardous to your health. If you suspect a leak, don’t hesitate to call an HVAC technician.
There aren’t many HVAC fixes that are DIY jobs, and this is especially true of issues with refrigerants. As a toxic substance, refrigerant can be highly dangerous. In fact, you need to have specific certifications to work with and dispose of refrigerants. If you want to check your levels or add more refrigerants to the system, you need to hire a trained professional.
Dirty Condensing Unit
The outdoor part of your AC is the condensing unit. To keep your system running, the condensing unit is responsible for transferring the humid air from inside your home.
Over time, cobwebs and other particles accumulate in the condenser. Debris from nearby bushes also has the potential to enter the unit. If enough dirt and debris accumulate, your system won’t blow cold air.
If you want your AC to keep you cool, you need a clean condenser. An HVAC technician knows how to clean your condenser thoroughly. Once all of the debris is gone, your system should be back in working order.
To prevent your condenser from getting dirty, keep shrubs and trees away from the exterior unit. If you have any near your unit, prune them back and clean up the branches immediately.
Bad Condenser Fan
While some AC problems are easy to fix, others are much more complex. If your AC isn’t cooling because of a bad condenser fan, the fix isn’t simple.
That said, it’s easy to know when your fan is bad. Look at the condenser and make a note of the fan. Is it spinning? If not, the fan motor may be broken. The unit won’t be able to break up heat, so it will send warm air into your home.
Your compressor is responsible for cooling the refrigerant. If the refrigerant doesn’t get cold, it won’t trap enough warmth to cool your air.
You may be able to tell if your cooling issue is coming from the compressor. Go outside and approach your condenser unit. Is there a noise coming from the unit? If not, your compressor isn’t working.
Unfortunately, a broken compressor is a costly fix. It’s usually cheaper to buy a new system than it is to fix a compressor. By the time your compressor fails, your system isn’t far from completely breaking down. You may need frequent repairs and find yourself spending more money than you would on a replacement AC. When your technician comes to diagnose the problem, they can explain more about the benefits of replacing your AC.
