Furnace Installation Services
When it’s time for a new furnace, our team is here to make the process seamless. We start by evaluating your home’s size, insulation, ductwork, and heating requirements to recommend the right size and capacity for maximum comfort and efficiency.
Why Our Installation Stands Out:

Frequently Asked Questions – Furnaces
1. Are high-efficiency furnaces worth it in Colorado?
Yes. High-efficiency (95%+ AFUE) models reduce fuel use during long heating seasons and can lower utility bills while improving comfort.
2. How do you size the right furnace for my home?
We assess your home’s square footage, insulation, windows, ductwork, and design temperature to recommend the correct capacity and stage (single, two-stage, or variable-speed).
3. Do you install dual-fuel systems (furnace + heat pump)?
Yes. We design dual-fuel setups that pair a high-efficiency gas furnace with a heat pump for efficient heating most days and powerful backup in extreme cold.
4. What’s included in furnace maintenance?
We inspect burners and heat exchanger, verify gas pressure and electrical connections, clean/replace filters, check safety controls, and confirm proper airflow and temperature rise.
5. Can you help with Xcel Energy rebates and financing options?
Yes. We advise on qualifying equipment, guide paperwork for Xcel rebates, and can discuss available financing options for new systems.
