Summer in Virginia brings warm temperatures, higher humidity, and a steady need for cool, comfortable indoor air. For homeowners, that means making sure your air conditioning system is up to the task.
Regular HVAC maintenance is essential, not just to keep things running efficiently, but to prevent inconvenient breakdowns during the hottest days of the year. If you want to stay ahead of the heat, here’s what you need to know about HVAC maintenance in Blue Ridge, VA and the most common summer service needs.
1. Air Filter Inspection and Replacement
One of the most important (and easiest) parts of HVAC maintenance is checking and changing your air filters. During summer, your system runs more frequently, and that means filters can become clogged with dust, pollen, pet dander, and other debris faster than usual. A dirty filter restricts airflow, forces your AC to work harder, and reduces indoor air quality.
2. Cleaning the Outdoor Condenser Unit
Your AC’s outdoor condenser unit is responsible for releasing the heat your system removes from your home. But during spring and early summer, it’s common for these units to become obstructed by leaves, grass clippings, dirt, and other debris. When airflow around the condenser is blocked, your system loses efficiency and could even overheat. Maintenance checklist:
- Remove any visible debris around the base of the unit
- Trim nearby bushes or weeds to allow for at least 2 feet of clearance
- Have a technician clean the condenser coils during a seasonal tune-up
3. Checking Refrigerant Levels
If your air conditioner isn’t cooling as well as it used to, the problem may be low refrigerant. A refrigerant leak not only impacts your comfort—it can damage the compressor if left unaddressed. Technicians performing HVAC maintenance should always check refrigerant levels as part of a summer inspection.
Signs of low refrigerant include
- Warm air blowing from vents
- Ice on refrigerant lines or evaporator coils
- Unusual hissing or bubbling noises
Only a licensed professional should handle refrigerant recharging or repairs, as the substance must be carefully managed under EPA regulations.
4. Thermostat Calibration and Battery Check
A misreading or unresponsive thermostat can throw off your entire cooling schedule. During routine maintenance, technicians test your thermostat for accurate temperature readings and replace the batteries if needed. If you’re still using a manual thermostat, this could be a great time to upgrade to a smart thermostat for added convenience and energy savings.
5. Electrical Component Inspection
Summer heat puts added demand on your HVAC system’s motors, capacitors, relays, and electrical connections. Loose wires or failing components can lead to breakdowns and even safety hazards. During HVAC maintenance, our technicians test voltage levels, tighten connections, and inspect all electrical parts to ensure safe operation through the season.
