Summers in Denver can be really warm. On a typical day, the temperature can reach 90 degrees. Many people spend more time in their air-conditioned homes to escape the heat. According to Energy.gov, air conditioners use 6 percent of the electricity used in the United States, showing how essential a functioning air conditioner is during the hot summer months.
During the hottest time of the year, the last thing you want is for your air conditioner to break down. One way to keep this from happening is to detect issues early so you can have the system repaired quickly, preventing a minor problem from becoming a major one. Because air conditioning Denver-based is so essential during the summer, you should call a professional if your system is experiencing any of the following issues.
#1 Warm Air
Warm air coming from the vents is one of the most obvious signs that you need to call an HVAC service. A common cause of this problem is human error. If your thermostat isn’t set to the cooling mode and it isn’t cooler in the house than the temperature setting, your system won’t produce cold air.
If your thermostat is correctly set, there are a few issues that could prevent your system from producing cold air.
- Faulty thermostat
- Dirty air filter
- Frozen evaporator coil
- No power to the outdoor unit
- Faulty compressor
- Low refrigerant level
- Refrigerant leak
#2 Poor Airflow
If the air flowing from the vents is inadequate, it will be difficult for your home to reach the desired temperature. Your system will need to work overtime to keep your home cool, which can cause your energy bills to increase and decrease your system’s lifespan.
The most common causes of poor airflow include:
- Clogged air ducts
- Broken or leaking air ducts
- Faulty blower
#3 Strange Sounds
Your air conditioner should be quiet when it runs. A faint clicking sound when the system cycles is normal, and any other sounds would require a call to an HVAC company. Strange sounds such as banging, clanging, screeching, hissing, and wailing are all signs that your system needs to be repaired.
Moisture or leaks around the system are signs that something is wrong. Moisture often signifies a loose or cracked condensate hose, which is a relatively simple fix. However, pooling liquid is more serious. This usually indicates a refrigerant leak. If your system is under 10 years old, the issue can be repaired, and the refrigerant can be refilled. If your system is older than 10 years, you have a serious problem.
According to the Environmental Protection Agency, R-22 is toxic and harmful to the environment. On January 1, 2020, R-22 was banned in the United States. If your system uses R-22, you will need to replace the system if you have a refrigerant leak. You rely on air conditioning services to stay cool and comfortable. If your system is exhibiting any of the following signs, you should call an HVAC service immediately.
