How often should I schedule HVAC maintenance?
It’s recommended to schedule HVAC maintenance at least twice a year—once in the spring for your AC and once in the fall for your heating system. Regular maintenance helps prevent unexpected breakdowns and improves efficiency.
What are the signs that my HVAC system needs repair?
Common signs include unusual noises, inconsistent temperatures, high energy bills, poor airflow, and unpleasant odors. If you notice any of these issues, it’s best to call for professional inspection and repair.
How can I improve indoor air quality in my home?
Improving indoor air quality can be achieved through regular duct cleaning, using air purifiers, maintaining proper humidity levels, and ensuring good ventilation. Our team can recommend the best solutions tailored to your needs.
Why is my energy bill so high even though my HVAC system seems fine?
High energy bills can result from poor insulation, leaky ducts, outdated equipment, or inefficient system operation. A home energy audit can help identify the root causes and suggest improvements to reduce energy consumption.
What size HVAC system do I need for my home?
The size of your HVAC system depends on factors like your home’s square footage, insulation, number of windows, and climate. Our experts perform detailed load calculations to recommend the right system for optimal efficiency.
