Frequently Asked Questions About HVAC Companies

What are the most common HVAC problems?

Common HVAC problems include:

• AC not cooling: Refrigerant leaks, compressor issues, or thermostat problems.
• Furnace not heating: Pilot light or ignition control issues, blower motor problems, or clogged filters.
• Uneven temperatures: Ductwork leaks, inadequate insulation, or faulty thermostats.
• Poor air quality: Dirty air filters, mold growth in ductwork, or inadequate ventilation.
• Strange noises: Unusual sounds from the system can indicate a variety of problems with different components.
• High energy bills: Inefficient systems, ductwork leaks, or improper thermostat settings.

If you're experiencing any of these issues, contact a qualified HVAC technician for diagnosis and repair.

How can I improve my home's indoor air quality?

You can take these steps to improve your indoor air quality (IAQ):

• Regular Air Filter Replacement: Change or clean your HVAC system’s air filters regularly (every 1-3 months).
• Professional Air Duct Cleaning: Have your air ducts cleaned by professionals every few years to eliminate dust, mold, and other contaminants.
• Improve Ventilation: Ensure adequate ventilation in your home to bring in fresh air and exhaust stale air. Use exhaust fans in kitchens and bathrooms.
• Control Humidity Levels: Use a humidifier or dehumidifier to maintain optimal humidity levels and prevent mold growth.
• Clean Regularly: Dust and vacuum frequently to minimize airborne particles.
• Avoid Smoking Indoors: Smoking indoors significantly reduces IAQ.
• Use Natural Cleaning Products: Opt for natural cleaning products that don’t release harmful VOCs (volatile organic compounds).
• Monitor Indoor Air Quality: Consider using an indoor air quality monitor to track pollutant levels.

If you have persistent IAQ issues, consult with an HVAC professional or an indoor air quality specialist for further assessment and solutions.

What is the difference between an AC unit and a heat pump?

While both air conditioners and heat pumps provide cooling, they differ in how they generate heat. An AC unit cools your home by extracting heat and transferring it outside. It uses a separate furnace or heating system for heating in colder months. A heat pump, however, can both cool and heat. In cooling mode, it functions like an AC, extracting heat from indoor air and releasing it outdoors. In heating mode, it reverses this process, extracting heat from the outside air (even in cold temperatures) and transferring it inside. This makes heat pumps more energy-efficient for heating than traditional electric resistance heating, especially in mild to moderately cold climates.

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.
