How Often Should a Professional Check My Air Conditioner?
To keep your air conditioner running for its entire life expectancy, schedule regular maintenance. A qualified technician should check your unit at least once a year. Scheduling the maintenance in spring ensures your unit runs at peak efficiency during the intense summer months.
If you want an extra measure of confidence, schedule a second maintenance check during the fall. This confirms nothing broke during your high summer usage.
What Does My Unit's Energy Rating Mean?
Your unit might have any of three different ratings measuring its energy efficiency.
Energy Efficiency Ratio (EER)
The EER measures your unit's cooling output and compares it to its energy use. Experts test the air conditioner at peak usage to verify its capacity and output. The higher the number, the more energy efficient the unit.
Seasonal Energy Efficiency Ratio (SEER)
The SEER calculates efficiency using seasonal averages rather than rigorous laboratory testing. Like the EER, a higher rating indicates better efficiency.
Heating Seasonal Performance Factor (HSPF)
If your system includes a heat pump, it has an HSPF. Just like the EER, it calculates heat output compared to energy usage. The higher the number, the better.
How Can I Reduce Energy Costs?
Your HVAC system can comprise up to 50% of your energy use. Use the following tips to help manage your energy costs:
- Upgrade to a newer air conditioner with a better EER rating
- An ENERGY STAR-rated system can save you $3 to $4 per square foot over its lifetime.
- Installing programmable thermostats helps you use energy only when you need it most.
- Schedule regular maintenance to avoid poor energy efficiency.
Why Do I Need Refrigerant So Often?
The refrigerant level should stay consistent over several years. However, if you find yourself replacing refrigerant every year, you have a leak. Refrigerant leaks prove harmful to your unit and the environment.
If you have a leak, call a qualified technician for repairs immediately.
Should I Worry About My Air Condition Leaking Condensation?
One of the most frequently asked questions about air conditioners concerns condensation. Because your unit extracts humidity from the air, seeing a little condensation is normal.
However, it can indicate a leak or clog somewhere in the system. Possible issues your AC unit may have include:
- A clogged condensate line
- A rusty condensate pan
- A dirty or frozen evaporator coil.
- Low refrigerant levels
- A dirty air filter
Call a professional to ensure they properly diagnose the issue.
How Do I Change My Air Filter?
To ensure your system runs at peak efficiency, change your air filter at least once every three months. If you live in a dusty climate or run it more than normal, you should check it more often. Follow these steps to change your filter:
- Verify what size air filter you need.
- Find a filter with a high energy efficiency rating (MERV).
- Choose a filter type from fiberglass, washable, pleated, or electronic.
- Follow the manufacturer's instructions for installation.
Can My Air Conditioner Control Humidity?
High humidity brings a host of problems, including mold growth, poor indoor air quality, damaged electronics, and airborne illness. When your air conditioner works as intended, it should easily keep your humidity between 40% and 60%. If you notice abnormal humidity even when your air conditioner runs, call a professional for a tune-up.
Is My Air Conditioner Broken?
If your air conditioner doesn't blow cold air, doesn't turn on, or makes weird noises, you likely have a broken unit. However, follow these steps before calling a technician for repairs:
- Confirm the thermostat works properly and replace batteries if needed.
- Check your fuse box or circuit breaker to verify it didn't trip.
- Check the air filter.
- Check and drain the condensate pan.
If the unit still doesn't work, call Hickory Heating & Cooling for repairs or replacement!
