Your home's windows and doors are like the eyes and mouth of your HVAC system – they can either help it perform efficiently or cause significant energy waste. Understanding how these openings affect your heating and cooling system can help you make informed decisions about improvements and maintenance.

Heat transfer through windows and doors can account for up to 30% of your home's heating and cooling costs. Modern, energy-efficient windows with double or triple panes and low-E coatings can dramatically reduce this energy loss. Similarly, properly sealed doors with adequate weatherstripping can prevent unwanted air infiltration and help maintain consistent indoor temperatures.

Regular maintenance of windows and doors is crucial for HVAC efficiency. Check for drafts around frames, ensure weatherstripping is intact, and consider adding window treatments like cellular shades or thermal curtains to provide additional insulation. RM Mechanical can perform a comprehensive energy audit to identify areas where your windows and doors might be compromising your HVAC system's efficiency.

Strategic window placement and usage can also help optimize your HVAC system's performance. During cooling seasons, using window coverings during peak sunlight hours can reduce solar heat gain. In winter, opening curtains on south-facing windows during the day can help capture natural heat, reducing the load on your heating system.

Investing in window and door upgrades can significantly improve your HVAC system's efficiency and reduce energy costs. Contact RM Mechanical for professional advice on how your windows and doors affect your HVAC system and recommendations for improvements that can enhance your home's comfort and energy efficiency.
