More Frequently Asked Questions
Common HVAC Problems
Q: Why is my AC blowing warm air?
A: Your AC may be blowing warm air due to low refrigerant levels, a clogged air filter, a malfunctioning thermostat, or a compressor issue. It's best to have a professional diagnose and fix the problem quickly to avoid further damage.
Q: Why is my HVAC system making strange noises?
A: Unusual sounds like banging, screeching, or rattling often indicate mechanical issues such as loose parts, motor problems, or debris inside the unit. Contact a technician to inspect your system before it worsens.
Q: What should I do if my HVAC system won't turn on?
A: First, check the thermostat settings, the circuit breaker, and the system’s power switch. If everything looks normal and the system still won’t start, call us for a professional inspection.
Buying & Costs
Q: How much does a new HVAC system cost?
A: The cost of a new HVAC system varies based on home size, system efficiency (SEER rating), brand, and any additional features like zoning or smart thermostats. On average, complete systems range from $8,000 to $15,000 installed. We offer free estimates and financing options.
Q: How do I choose the right size HVAC system for my home?
A: Proper sizing depends on factors like square footage, insulation quality, number of windows, and home layout. Our team performs a full load calculation to recommend the correct system size for maximum efficiency and comfort.
Energy Efficiency
Q: How can I lower my energy bills with my HVAC system?
A: Regular maintenance, using a programmable thermostat, sealing ducts, replacing old filters monthly, and upgrading to a high-efficiency unit (with a higher SEER rating) can significantly reduce energy costs.
Q: What is a SEER rating, and why does it matter?
A: SEER (Seasonal Energy Efficiency Ratio) measures the efficiency of an air conditioning system. Higher SEER ratings mean better energy efficiency, which can lower your cooling costs over time.
System Lifespan and Upkeep
Q: How long does an HVAC system typically last?
A: Most HVAC systems last between 10 to 15 years with proper maintenance. Regular tune-ups and timely repairs can help extend the life of your system.
Q: Is HVAC maintenance really necessary?
A: Yes! Maintenance improves system performance, increases energy efficiency, prevents costly repairs, and can even extend the life of your system. Many manufacturer warranties also require regular maintenance to stay valid.
