Why Do I Need to Keep Adding Refrigerant?
If you find yourself constantly adding refrigerant, there is likely a leak in your system. Air conditioners are designed to keep a consistent refrigerant level unless there is a problem. A leak not only affects the environment but also makes it harder to maintain your AC. Rather than constantly refilling the system, contact our professionals. We’ll quickly identify and fix the leak. If your system uses outdated refrigerant, upgrading to a newer AC model could provide long-term benefits, including energy savings and rebates.
Why Does My Air Conditioner Freeze Up?
The most common cause of a frozen AC unit is either restricted airflow or a refrigerant leak. Begin by replacing the air filter, which often solves airflow issues. If that doesn’t help, check for any blockages around your air return. If the issue persists, contact Dave’s Heating and Air Conditioning. Our team in Reston can quickly diagnose and repair your AC unit.
Steps to Take Before Requesting AC Service
Before calling us for AC repair in Reston, make sure you check these common troubleshooting points:
- Check the breaker box for any flipped switches
- Ensure the air filter is clean
- Make sure the thermostat is set to “cool” and the correct temperature
- Verify that the furnace switch is on
- Replace the thermostat batteries if needed
- Confirm the outdoor AC unit is unobstructed
If none of these steps fix the issue, contact Dave’s Heating and Air Conditioning at 571.346.3940. We’ll get your AC back to working condition.
How to Prevent AC Repairs in Herndon
While it’s impossible to completely eliminate the risk of AC breakdowns, you can reduce the likelihood with regular maintenance and heating. Routine HVAC check-ups allow a technician to inspect your system for potential issues and ensure it’s operating efficiently. This proactive approach helps prevent unexpected mid-season breakdowns. Contact us to learn more about our HVAC maintenance services in Reston.
Why Isn’t My AC Cooling?
If your air conditioner is running but not cooling, there are three common issues to consider:
- Condenser Problems: Outdoor condensers can get blocked by debris like leaves or tree shedding. Make sure the area around your condenser is clear by at least three feet.
- Dirty Filters: Check your furnace filter, as a dirty one can restrict airflow. If it’s darker than light gray, replace it and allow the system to adjust.
- Evaporator Coil Issues: If the evaporator coil has ice on it, it may not be effectively removing heat from the air.
If these steps don’t resolve the issue, call us at 571.346.3940 for professional assistance.
Why Is My AC Unit Leaking?
Water pooling beneath your air conditioner isn’t always a cause for alarm—it’s part of the cooling process. However, if the water doesn’t stop or you notice significant puddles, your system likely needs attention. In Reston, clogged drains or a faulty drain pan are frequent culprits that can lead to water damage if ignored.
What Temperature Should AC Air Be?
Your AC should cool the air by 15 to 20 degrees compared to the outdoor temperature. If you notice warm air, run the unit for about 15 minutes to see if it stabilizes. Persistent warm air could be due to problems like a dirty air filter or an evaporator issue, both common in Reston.
Why Is My AC Making Unusual Sounds?
If your air conditioner is louder than usual, it may need immediate attention. Potential causes include worn-out parts, a malfunctioning blower, a damaged compressor, or unbalanced fan blades. For accurate diagnosis and repair, schedule a professional inspection with Dave’s AC experts.
What’s Causing That Smell from Your AC?
Strange smells from your air conditioner can indicate a problem. Mold or mildew buildup is a common culprit. If you’re not sure what’s causing the odor, contact Dave’s – we are familiar with all AC brands. Our experts service all AC brands, and a tune-up in Reston is usually all it takes to fix the issue.
What to Do If Your AC Won’t Turn Off
When your air conditioner keeps running despite your home being cool, check if the thermostat is set to ‘Auto’ rather than ‘On.’ If it’s correctly set and the problem continues, reach out to an HVAC expert. The issue could be as simple as a clogged filter or as complex as an improperly installed or oversized unit, which can affect humidity control
Tips for Improving AC Efficiency
Start by keeping all vents open—closing them can raise energy costs. Scheduling Regular maintenance is also essential to keep your system clean and running smoothly. Installing blackout curtains can reduce heat and light, easing the workload on your AC. Lastly, using a ceiling fan helps circulate air, making it easier to stay comfortable during milder temperatures in Reston and Herndon.
