General HVAC Questions

Your HVAC system should be serviced at least twice a year—once in the spring for your air conditioning and once in the fall for your heating. Regular maintenance helps keep your system running efficiently and prevents costly repairs.

If your system is over 10-15 years old, requires frequent repairs, or is no longer energy-efficient, it might be time to consider a replacement. If it’s a minor issue, such as strange noises or inconsistent temperatures, a repair might be sufficient. A professional technician can evaluate your system and provide recommendations.

The size of your HVAC system depends on factors like the square footage of your home, insulation, and climate. An HVAC professional can perform a load calculation to determine the right size for your needs.

  • Schedule regular maintenance.
  • Replace air filters every 1-3 months.
  • Seal leaks in ductwork.
  • Install a programmable thermostat.
  • Ensure proper insulation in your home.

SEER (Seasonal Energy Efficiency Ratio) measures the efficiency of an air conditioning unit. The higher the SEER rating, the more energy-efficient the system, which can save you money on energy bills.
