Air Conditioner Service
For most people, central air conditioning is a matter of comfort during hot, humid summer months. For others, especially the elderly, it can be a health issue. Some studies have linked high heat and humidity with increased risk of heart attacks*, for example. Regardless of why you enjoy them, air conditioners are great when they are running smoothly. But when the temperatures outside are rising and the temperature and humidity are rising inside as well, it can be cause for stress, and even a potential safety concern. That’s why air conditioner service can be an important expenditure.
Keep in mind that not every air conditioning system breakdown will fall under the label of emergency service. Sometimes it’s an easy fix that can be handled with a system adjustment, cleaning or minor repair. It’s never a good day when your air conditioning system stops working and you need to call a service technician for repair services... but the sooner you call, the sooner you’ll be back to enjoying cool comfort.
Air Conditioner Repairs
Central air conditioning units are often part of a complete cooling and heating system. If you have an all-electric system, your air conditioning might actually be supplied by a heat pump. Either way, there are a number of components involved and a number of ways the system can malfunction. Some examples include:
- Running constantly / Not keeping up with cooling needs: Every AC system will work a little harder on hotter, more humid days. But if your system seems to run constantly with less than adequate cooling, you may have a problem lurking. An undersized unit will struggle when demand is high. Low refrigerant levels can cause longer and less effective cooling cycles. A dirty air filter, dirty evaporator coil (inside) or dirty condenser coil (outside) can reduce efficiency and effectiveness as well. Try cleaning or replacing the air filter or before contacting a professional for air conditioner repair service.
- Repeatedly starting then stopping (short cycling): If your system seems to start and then shut off over and over, you may have a system that was oversized by the installing dealer. Low refrigerant levels can also be hard on AC systems, causing them to run erratically. A clogged or excessively dirty air filter and a frozen or dirty evaporator coil can have the same effect. Cleaning or replacing the air filter may help, but cleaning an evaporator coil requires an air conditioner service call.
- Weak or no airflow: Two-stage or multi-stage cooling systems often run for longer periods of time on a lower fan setting. If your indoor temperature matches the temperature you set on the thermostat, your system is operating normally. However, if you have weak or no airflow and the temperature continues to rise inside, you may have an issue. This could signal a dirty air filter or an issue with the indoor unit’s blower or fan motor. Try changing or replacing the air filter before contacting a professional.
- Not running at all: Before calling a Carrier® dealer for in-home services or repair, check your thermostat to make sure the system hasn’t been turned off. Then, check your electrical panel to be sure a fuse hasn’t blown or breaker hasn’t tripped. Also check your air filter for excessive dirt or clogging. If everything checks out, it’s time to call a professional. Most air conditioners include some built-in sensors that can shut down operation under abnormal conditions to help prevent damage to vital (and expensive!) components like the compressor, evaporator coil and condenser coil.
- Unusually high energy bills: During the heat of the summer your system will work harder and more often, so you may see higher electric bills. If your utility bill seems unusually high compared to the previous month’s (or previous year’s bill for the same month), it might be time to investigate. Check the air filter and outdoor condenser coil for excessive dirt and clogging. If everything checks out, or if you see buildup of ice on the outdoor coil or the copper refrigerant tubing, call an HVAC technician for professional air conditioner repair service.
Finding an Air Conditioner Repair Service Near You
When your air conditioner stops running, don’t always assume the worst. Before you jump to the “repair or replace” conversation in your head, do a little investigating on your own. You might be surprised that the issue is something you can resolve yourself. But don’t wait too long before calling a Carrier HVAC Dealer. Even a minor problem can become a major problem if it’s not addressed. More importantly, the longer you wait, the longer it will be before you can enjoy the cool comfort of your home.
