Frequently Asked Questions About HVAC Companies

What regular maintenance should I do on my HVAC system?

You can perform some simple maintenance tasks on your own to keep your HVAC system running smoothly:

• Change Air Filters: Change or clean your air filters every 1-3 months. Dirty air filters restrict airflow and decrease system efficiency.
• Clear Debris: Ensure there are no obstructions near the vents inside your home.
• Check Thermostat Settings: Make sure your thermostat is set to the desired temperature and is functioning correctly.

For more complex maintenance, like cleaning coils or checking refrigerant levels, contact a qualified HVAC technician. Schedule annual or biannual maintenance with a reputable HVAC contractor.

How do I choose the right size AC unit for my home?

Choosing the right AC unit size is essential for efficient cooling. An undersized unit won’t cool your home adequately, while an oversized unit will cycle on and off frequently, wasting energy and leading to premature wear and tear. A qualified HVAC technician will calculate the appropriate size AC unit for your home based on factors like:

• Your home's square footage
• Your local climate
• Insulation levels
• Window efficiency
• Number of occupants

This calculation involves determining your home's cooling load, typically measured in BTUs (British Thermal Units). Don’t rely on estimates or guesswork; consult with an HVAC professional to ensure your new AC unit is properly sized for your specific needs.

What are the signs my air conditioner needs refrigerant?

Low refrigerant levels can cause various problems with your air conditioner:

• Warm Air: The most noticeable sign is that the AC is blowing warm or not cool air.
• Ice Buildup: Ice may form on the refrigerant lines or evaporator coil.
• Increased Energy Bills: Your system has to work harder to cool, leading to higher energy consumption.
• Hissing or Bubbling Sounds: These sounds can indicate a refrigerant leak.

If you suspect low refrigerant, contact an HVAC technician to fix the leak and add refrigerant.

How can I reduce my HVAC energy consumption?

You can reduce HVAC energy consumption and lower your bills by:

• Regular Maintenance: Schedule annual HVAC maintenance to ensure your system is running at peak efficiency.
• Programmable Thermostat: Use a programmable or smart thermostat to optimize temperature settings based on your schedule.
• Seal Air Leaks: Caulk and weatherstrip windows and doors to prevent drafts.
• Proper Insulation: Ensure adequate insulation in your attic, walls, and floors to prevent heat loss in winter and heat gain in summer.
• Ventilation: Use fans strategically to circulate air and reduce reliance on AC.
• Energy-Efficient Appliances: Choose energy-efficient appliances to reduce your overall energy load.
• HVAC Zoning: Consider zoning your HVAC system to condition different areas of your home separately.
