HVAC Frequently Asked Questions

HVAC stands for Heating, Ventilation, and Air Conditioning. Our certified technicians specialize in diagnosing and servicing complete home climate systems. You might need our expertise when upgrading your home, moving into a new property, or experiencing any indoor comfort issues.

Consider replacement when:

• Your system is over 10 years old
• You’re experiencing frequent breakdowns and repairs
• Your energy bills are steadily increasing
• Your home has comfort inconsistencies
• You’re planning major home renovations

Repairs are typically recommended when:

• Your equipment is less than 10 years old
• The issue is clearly identified and isolated
• The repair cost is significantly less than replacement
• Your system has been properly maintained

Winter energy savings:

• Seal air leaks around doors and windows
• Keep garage doors closed
• Replace dirty filters regularly
• Program your thermostat to lower temperatures when you’re away or sleeping

Summer energy savings:

• Set your thermostat to the highest comfortable temperature
• Use ceiling fans to improve air circulation
• Position electronics away from your thermostat
• Install shade plants around outdoor units
• Consider a professional energy audit to identify efficiency opportunities

• Confirm circuit breakers are on and fuses are intact
• Check that air filters are clean
• Ensure all vents are open and unobstructed
• Verify your thermostat is on the correct settings
• Check that the outdoor unit is clear of debris

SEER (Seasonal Energy Efficiency Ratio) measures the cooling efficiency of air conditioners and heat pumps. Higher SEER ratings indicate greater energy efficiency and lower operating costs. Modern systems must have a minimum 13.0 SEER rating, with high-efficiency models reaching 20+ SEER.

ENERGY STAR is an EPA program that identifies high-efficiency heating and cooling products. ENERGY STAR certified equipment meets strict efficiency guidelines and can significantly reduce your utility bills while helping protect the environment.

Most systems last 10-15 years, though this varies based on maintenance, usage patterns, and local climate conditions. We recommend professional efficiency evaluations after 5 years of service. Regular preventative maintenance can extend your system’s lifespan and maintain peak performance.

Our maintenance plans are customized based on your specific equipment and needs. Preventative maintenance typically costs far less than emergency repairs and extends the life of your equipment.

Annual professional cleaning and inspection is essential for safety and efficiency. Older systems may require more frequent service. Regular maintenance prevents carbon monoxide leaks that can develop as furnaces age.

Clean ducts contribute to:

• Healthier indoor air quality
• Reduced allergy symptoms
• Improved system efficiency
• Lower energy costs
• Extended equipment life

We recommend professional duct cleaning every 3-5 years, or immediately if you notice unusual health symptoms, visible mold, or pest evidence.

Comprehensive duct cleaning addresses all components of forced air systems, including:

• Supply and return air ducts
• Registers, grilles, and diffusers
• Heat exchangers
• Heating and cooling coils
• Condensate drain pans
• Fan components and housing
• Air handling unit

Proper humidity levels:

• Prevent dry skin, irritated sinuses, and respiratory discomfort
• Protect wooden furniture from cracking
• Reduce static electricity
• May lower heating costs (properly humidified air feels warmer)
• Help preserve household items and surfaces

Strategic landscaping can improve efficiency by providing shade, but proper spacing is crucial. Keep plants at least 2-3 feet away from all sides of the unit to ensure unrestricted airflow. Regular trimming and maintenance are essential.

Standard 1-inch filters typically need monthly replacement during peak usage seasons. High-efficiency filters may last 3-6 months. Inspect filters regularly and replace when visibly dirty – clean filters significantly impact system efficiency and indoor air quality.

Rather than completely shutting down your system, adjust your thermostat 7-10 degrees toward the outside temperature when away. This approach balances energy savings with the ability to quickly restore comfort upon return, while maintaining humidity control.

Professional sizing calculations consider:

• Home square footage
• Local climate conditions
• Insulation quality
• Window efficiency and quantity
• Home orientation and shade
• Number of occupants
• Heat-generating appliances
• Ceiling heights
• Ductwork design

Oversized systems cycle too frequently, causing humidity control issues, while undersized systems run constantly without achieving desired comfort.
