Imagine being outside on a hot summer day. You head inside for some relief, but don’t feel any cooler. As you walk under the vent of your HVAC system, you feel air blowing out, but it’s not cooling you down. If you want relief, you need to call an AC service in Tampa. To prepare yourself for this situation, you should know why your air conditioner might not feel cool.
Reasons Your AC Might Not Be Cool
Unless you’ve had training as an HVAC technician, you probably don’t know what’s wrong with your system. But you may not need AC repair in Tampa to figure out what the problem is. If your AC isn’t cool, all of the following issues could be to blame.
1. Your Thermostat Settings Aren’t Right
Sometimes, the problem is an easy fix. It’s not uncommon for thermostat settings to be the problem. If your thermostat is set to fan mode, it won’t always blow cold air. When your home is the right temperature, the fan will circulate uncooled air.
While there’s nothing wrong with running the fan mode, it can trick you into thinking that your AC isn’t working. It will also boost your energy use and cost you more on your monthly bills.
There could be another issue with your thermostat. If you have a smart thermostat, there’s a significant chance of user error. You could have the system on a setting that automatically sets your temperature at certain times of the day. Dropping your thermostat won’t override that setting, so your house could be warmer than you like.
2. Dirty Filter
A dirty filter might be the cause of your warm air. As your HVAC system works, it pulls air through vents. Air filters purify the air before they go through your system by removing allergens, dust, and other particles. However, those filters can only hold so many particles. When they get too full, the filters reduce the airflow in your system.
Less air in your system means less air flows over your evaporator coil. When the air goes through the coil, it could freeze up. The cooling system halts, and you won’t get any cold air in your home.
Preventing this from happening is easy. To keep your air flowing, replace your filters frequently. Once every three months, change out your filter. If you have a reusable filter, you don’t need to replace it as frequently. Instead, clean your filter every three months. Doing so will also improve your indoor air quality
3. Low Refrigerant
There are several crucial components that your air conditioner needs to work properly. One such component is the refrigerant. If your system has low refrigerant, it might not blow cool air.
Refrigerant changes from a gas to a liquid as it travels from the indoor evaporator coil to the exterior condensing unit. When refrigerant levels are low, the evaporator coil could freeze up. Even if the coil doesn’t freeze up, your system may not make enough cold air. In either case, you need AC repair in Tampa to replace your refrigerant. You need special licensing to work with refrigerant, so you can’t fix this issue on your own.
4. Dirty Condensing Unit
The exterior part of your AC is the condensing unit. Because this part is exposed to the elements, it has the potential to get dirty. Cobwebs, leaves, and other debris often clog up the fins of the condenser.
If there’s too much debris in the condenser, your system won’t work well. You can remedy this by cleaning the condensing unit, but that’s easier said than done. To avoid damaging your AC, you may want to rely on a professional.
One way to prevent this from occurring is to keep trees and shrubs away from your unit. If you do have them too close to your condensing unit, keep them trimmed far back from your exterior unit.
5. Bad Compressor or Condenser Fan
If your AC is on, the fan at the top of the condensing unit should spin. Without the fan, your system won’t work. The unit won’t break up heat, and warm air will circulate throughout your home.
In addition to seeing the fan spin, you should also hear the compressor humming. The compressor cools the refrigerant, which powers your whole system. If your compressor doesn’t work, your refrigerant won’t trap enough heat to keep your home cool.
If you only hear silence or weird noises when your compressor should be running, you may have a broken compressor. Unfortunately, this part is extremely expensive to replace. You may be better off replacing your entire AC system
6. Leaking Ducts
If you have a traditional HVAC system, your Ductwork could be the reason your system isn’t working well. A leak in your ducts allows air to escape. As a result, your system isn’t as efficient as it should be. The escaping air keeps your home from reaching the optimal temperature.
To prevent leaking ducts, you should have your ducts cleaned and inspected. When you have no leaks, your system can do its job.
7. The System is too Small
An AC that’s too small won’t effectively cool your home. It just doesn’t have enough power to handle your cooling demands. Although your system turns on, it won’t be able to keep your home a comfortable temperature.
Sadly, there’s no easy fix for this. Your only options are to replace your existing system with a larger one, or to live in discomfort. If you’re getting a new HVAC system, it’s important to get it sized properly. Ask your HVAC technician what size would work best for your home. Whether a system is too small or too large, it could cause your problems.
