Our Furnace Installation Services
A successful furnace installation begins with careful planning and professional workmanship. Installing a system that’s too small will leave your home struggling to reach the right temperature, while an oversized unit will short-cycle, wasting energy and reducing its lifespan. At Michael Bonsby, our process includes detailed load calculations, airflow testing, and duct inspections to make sure your system is perfectly sized for your home’s square footage and heating demands.
Once we identify the right system, our trained installers handle everything from safely removing your old unit to connecting gas, electrical, and ventilation lines for your new furnace. We double-check all connections and run performance tests to confirm safe and efficient operation. We install top-quality brands, including American Standard and Mitsubishi, giving you access to some of the most reliable furnaces on the market.
With every furnace installation, you can expect respect for your home, clear communication from start to finish, and results that keep you warm for years to come.
Benefits of an Energy-Efficient Furnace System
Investing in a high-efficiency furnace during your furnace installation can transform the way your home feels throughout winter. These modern systems aren’t just about heating — they’re about creating comfort and savings every single day. Here’s why homeowners choose efficiency:
- Cost savings: High-efficiency models use less energy to deliver the same warmth, leading to significant savings over time. Many homeowners see their heating bills drop by 20% or more after upgrading.
- Rebates & incentives: Programs in Maryland and DC often offer rebates or tax credits for ENERGY STAR® certified systems. These incentives can reduce the upfront cost of your furnace installation.
- Eco-friendly heating: By reducing fuel consumption, efficient furnaces lower greenhouse gas emissions, helping protect the environment while keeping your home cozy.
- Improved indoor air quality: Advanced filtration in modern furnaces helps remove dust, pollen, and other particles, contributing to cleaner indoor air and better respiratory health.
- Quiet comfort: Unlike older models, efficient furnaces operate quietly, with variable-speed motors that provide even, consistent heat without noisy cycling.
- Smart home compatibility: Many systems integrate with smart thermostats and apps, giving you control over comfort and energy use from your phone.
Energy efficiency is more than a selling point — it’s peace of mind knowing your furnace is working smarter, not harder.

Furnace Installation FAQs
How long does a furnace installation take?
Most furnace installation projects are completed in a single day. For larger homes or when additional ductwork or electrical updates are needed, the process may take longer. We provide clear timelines before starting work so you know what to expect.
What size furnace do I need?
The right furnace size depends on several factors, including home size, insulation levels, and duct design. Our technicians perform load calculations to ensure your system is neither oversized nor undersized, maximizing efficiency and comfort.
Do high-efficiency furnaces really save money?
Yes. ENERGY STAR® models use significantly less fuel than standard units. Over 10–15 years, homeowners can save thousands in utility costs, often offsetting the higher upfront price of the system.
When should I replace instead of repair my furnace?
If your system is over 15 years old, requires frequent repairs, or your heating bills are steadily increasing, replacement may be more cost-effective. We provide honest recommendations based on your system’s condition and your household needs.
