How to Choose the Right HVAC System for Your Home
Selecting the right HVAC system is critical to ensuring energy efficiency, optimal performance, and long-term savings. Here are the key factors to consider when choosing the perfect heating and cooling system for your home in Lake Stevens:
Size and Capacity
An oversized or undersized unit can lead to inefficiency, frequent breakdowns, and higher utility costs. Our experts at Green City Heating and Air Conditioning perform detailed load calculations to ensure you get the right-sized system for your home.
Energy Efficiency Ratings
Energy-efficient systems can significantly reduce your heating and cooling costs. Look for SEER (Seasonal Energy Efficiency Ratio) ratings for air conditioners and AFUE (Annual Fuel Utilization Efficiency) ratings for furnaces. We help customers select ENERGY STAR®-certified systems that qualify for energy rebates.
