For optimal comfort and energy savings during summer, set your thermostat to 78°F (25°C) when you’re home. If you’re away, raising it to 85°F can help reduce cooling costs. Using a programmable or smart thermostat can make these adjustments automatic and more efficient.

To improve indoor air quality, start by regularly changing your HVAC filters, scheduling routine maintenance, and using air purifiers. Consider duct cleaning if your home has excessive dust or allergy symptoms. Proper ventilation and keeping your home clean are key to healthier air.

It’s recommended to have your furnace professionally serviced once a year, ideally in the fall before the heating season begins in Aubrey and Celina. Annual maintenance helps ensure safe operation, improves efficiency, and can extend the life of your system.
It’s generally recommended to have your air ducts cleaned every 3 to 5 years in Aubrey and Celina, or more often if you notice dust buildup, allergies, or musty odors. Homes with pets, recent renovations, or high pollen levels in Aubrey may benefit from more frequent cleanings to maintain healthy indoor air quality.
You should schedule AC maintenance once a year, ideally in the spring before the cooling season starts in TX. Regular tune-ups help your system run efficiently, prevent breakdowns, and extend the life of your unit, especially important in our summer climate.
The right HVAC system size for your home in North TX depends on factors like square footage, insulation, number of windows, and local climate.
