Common Residential HVAC FAQs
Answers to Your Heating & Cooling Questions
As the seasons change, homeowners often find themselves adjusting their HVAC systems to maintain comfortable temperatures indoors. However, HVAC systems are complex and can raise various questions.
The experts at Suburban HVAC are here to address some of the most frequently asked questions about residential HVAC systems, helping you understand their functioning and optimize their performance.
How often should I replace my HVAC air filters?
Air filters should typically be replaced every one to three months. However, this can vary depending on factors such as the type of filter used, indoor air quality, and the presence of pets.
Regular filter changes ensure efficient airflow, maintain indoor air quality, and extend the life of your HVAC system.
Why is my HVAC system making unusual noises?
Unusual sounds such as banging, rattling, or squealing can indicate various issues, including loose components, worn-out belts, or failing motors. These noises should always be addressed promptly, as they may lead to more significant problems if left unresolved.
Contact a professional HVAC technician to diagnose and resolve the issue.
What is the ideal temperature setting for my HVAC system?
The ideal temperature setting varies from person to person, but the U.S. Department of Energy recommends setting your thermostat to 78°F (26°C) during the summer and 68°F (20°C) during the winter for optimal energy efficiency.
How can I improve the energy efficiency of my HVAC system?
To improve energy efficiency, consider these tips:
- Regularly maintain and clean your system.
- Install a programmable thermostat to adjust temperatures based on your schedule.
- Seal air leaks in your home to prevent energy waste.
- Upgrade to a more energy-efficient HVAC system if yours is outdated.
Why is my HVAC system freezing up?
A frozen HVAC system may be caused by restricted airflow, low refrigerant levels, or issues with the compressor. Turn off the system immediately and contact an HVAC professional to identify the root cause and prevent further damage.
Should I close vents in unused rooms to save energy?
Closing vents in unused rooms can create imbalances in your HVAC system, leading to reduced efficiency and potential damage. Instead, consider zoning systems or adjusting the thermostat to save energy while maintaining proper airflow.
What are HVAC SEER ratings?
SEER (seasonal energy efficiency ratio) ratings measure the cooling efficiency of air conditioners and heat pumps. Higher SEER ratings indicate better energy efficiency.
When buying a new HVAC system, look for a higher SEER rating to save on energy costs in the long run.
Can I perform HVAC maintenance myself?
While some basic maintenance tasks, such as changing air filters, can be done by homeowners, it’s best to leave more complex tasks to professionals. Professional HVAC technicians have the knowledge and tools to perform thorough inspections, identify potential issues, and ensure your system runs optimally.
How long does an HVAC system typically last?
The life span of an HVAC system can vary depending on the brand, model, and maintenance schedule. On average, a well-maintained HVAC system lasts 15 to 20 years. Regular maintenance is key to extending the life and reliability of your HVAC equipment.
What should I do if my HVAC system isn't heating or cooling properly?
If your HVAC system isn’t heating or cooling as expected, check the thermostat settings, change the air filter, and ensure the circuit breaker is on. If the issue persists, it’s time to call a professional HVAC technician to diagnose and fix the problem.
