HVAC Frequently Asked Questions
How often should I change my HVAC air filters?
Most homes benefit from replacing filters every 1–3 months. If you have pets, allergies, or higher dust levels, we may recommend more frequent changes to maintain airflow and keep your system running efficiently.
How often should my HVAC system be serviced?
We recommend professional HVAC maintenance twice a year—once in spring and once in fall—to prepare your system for peak heating and cooling seasons and ensure optimal performance.
What size HVAC system does my home need?
The right HVAC size depends on home square footage, insulation, windows, layout, and ductwork design. Our technicians perform a full load calculation to determine the most efficient and properly sized system for your home.
How can I improve the energy efficiency of my HVAC system?
Energy efficiency improves with regular maintenance, clean filters, upgraded thermostats, proper insulation, sealed ductwork, and using ceiling fans for better airflow. In some cases, upgrading to a high-efficiency system offers significant long‑term savings.
What is the typical lifespan of an HVAC system?
Most HVAC systems last 10–15 years. Routine maintenance can extend this lifespan, while outdated or heavily used systems may need replacement sooner.
Why is one room in my home warmer or cooler than the others?
Uneven temperatures are often caused by duct design issues, airflow restrictions, insulation gaps, or draft‑prone windows. We can inspect your system and recommend solutions to balance comfort throughout your home.
