How often should I schedule HVAC maintenance?
We recommend scheduling maintenance for your AC system in the spring and your heating system in the fall. Regular maintenance helps prevent breakdowns and ensures optimal performance.
What are the signs that my AC needs repair?
Common signs include unusual noises, weak airflow, warm air blowing from the vents, and higher-than-normal energy bills. If you notice any of these, contact us for a prompt inspection.
How can I improve indoor air quality in my home?
Regular duct cleaning, using high-quality air filters, and installing air purifiers or humidifiers can significantly improve indoor air quality.
Are heat pumps energy-efficient?
Yes, heat pumps are highly energy-efficient because they transfer heat rather than generating it. They can provide both heating and cooling, making them a cost-effective option for many homes.
What is included in a home energy audit?
Our home energy audit includes a comprehensive evaluation of your home’s insulation, HVAC systems, ductwork, windows, and more to identify areas where you can improve energy efficiency and reduce costs.
