Proper Sizing & Load Calculation — Not Overselling

If anything doesn’t perform as promised after installation, we come back and make it right — no runaround. Your heating investment is fully protected by both the manufacturer’s warranty and our own labor guarantee.

Our Process
From Consultation to Startup: How We Install Your Furnace
Installing a new furnace is a bigger decision than a repair, so our process is built around getting every detail right before equipment is ordered. Each step gives you a clear picture of what you’re buying and why, with no surprises or pressure along the way.
1. In-Home Heating Needs Assessment & Building Evaluation
The process starts with one of our technicians walking your home, not quoting over the phone. During this visit we:
- Inspect your existing furnace, ductwork, and thermostat to understand current performance
- Walk through every room to identify temperature variations, comfort gaps, and problem areas
- Assess insulation levels, air leaks, attic conditions, and ductwork integrity
- Review your home’s age, construction, and square footage to understand heating demands
- Discuss your household’s heating habits and comfort priorities — whether that’s consistent warmth, quiet operation, or lower energy costs
2. Professional Load Calculation & System Sizing
Correct sizing is the foundation of a successful installation. We never eyeball it. Our load calculation accounts for:
- Total square footage and the three-dimensional layout of your home
- Insulation quality, basement conditions, and exposure to outdoor air
- Minnesota’s severe winter climate and the temperature rise your system must handle
- Ductwork configuration and any airflow constraints
From that analysis we explain the BTU output your home actually needs and why undersizing leaves you cold on the harshest days, while oversizing wastes money and reduces efficiency.
3. Equipment Recommendations & Payment Options
Once we know what your home needs, we present real options rather than a single take-it-or-leave-it price. In this step we:
- Show you several Lennox systems, from reliable standard-efficiency models to premium high-efficiency units with variable-speed blowers
- Explain the practical differences between efficiency tiers in plain language
- Point out any manufacturer rebates, Xcel Energy incentives, or local offers you may qualify for
- Provide clear upfront quotes so you can compare your options side by side
- Walk through flexible financing through Service Finance so the investment fits your household budget
4. Professional Furnace Installation by Certified Technicians
After you’ve chosen your system, our NATE-certified installers handle the complete installation from start to finish:
- Safe removal and disposal of your old furnace, including proper handling of gas connections
- Setting the new unit in place and verifying it’s level and stable
- Connecting all gas, electrical, and thermostat wiring according to manufacturer specs
- Sealing and pressure-testing gas connections to ensure safety
- Inspecting and sealing ductwork so heated air reaches every room efficiently
- Installing a new air filter and verifying all controls function properly
Most installations are completed in a single day, though larger jobs or extensive ductwork work may take longer.
5. Complete System Testing, Homeowner Education & Warranty Registration
Before we’re done, we verify the system works perfectly and that you understand how to use it. This final step includes:
- Running a full heating cycle and confirming even, comfortable warmth throughout your home
- Measuring temperature rise and testing all system controls and safeties
- Verifying your thermostat communicates correctly with the new furnace
- Registering your equipment with the manufacturer and providing warranty documentation
- Walking you through basic operation, thermostat settings, air filter replacement schedules, and maintenance tips so you get years of reliable comfort from your investment
Common Questions
Frequently Asked Questions About Furnace Installation
If your furnace is aging, requires frequent repairs, doesn’t heat your home evenly, or your heating bills are consistently rising, replacement may be more cost-effective than repairs. A new, high-efficiency furnace typically uses significantly less fuel than an aging unit, which translates to real savings on winter heating bills. We’ll evaluate your situation and honestly recommend repair or replacement based on your home’s needs and your budget.
System size is measured in BTUs (British Thermal Units), and the right number depends on your specific home. A proper sizing calculation considers your square footage, insulation level, local climate severity, the age of your home, and ductwork condition rather than rough rules of thumb. Oversizing wastes fuel and causes short cycling, while undersizing leaves you cold on the harshest nights. We calculate the exact capacity your home requires before recommending any equipment.
Standard-efficiency furnaces send a portion of their fuel out the flue as waste heat, while high-efficiency models capture much more of that energy and deliver it to your home. The difference shows up on your monthly heating bills, especially through a long Minnesota winter. Over the life of the furnace, those savings often offset a meaningful share of the equipment cost. We’ll show you the efficiency rating of each option and help you compare based on your budget and timeline.
Yes, in most cases. We inspect your ductwork and make repairs if needed to ensure efficient airflow with your new furnace. If your air conditioning system is also aging, pairing your furnace with a new air conditioning installation lets both units work as a matched system for optimal year-round comfort and efficiency. Financing often makes doing it all at once more affordable than staggering replacements.
Most installations take 4–8 hours depending on system complexity and ductwork condition. A straightforward replacement of an existing furnace in its original location is often finished in a single day. Jobs involving ductwork repairs, thermostat upgrades, or first-time heating may take longer. We’ll give you a realistic time estimate upfront, work efficiently to minimize disruption, clean up thoroughly, and test everything before we leave.
We specialize in Lennox as a Premier Dealer and also install GE, Ruud, Navien, and other quality brands. Our recommendation is based on your home’s needs, budget, and efficiency priorities — not on what carries the biggest margin. We’ll walk you through the options and explain the trade-offs so you can make an informed choice.
Yes. Through Service Finance, we offer flexible financing so you can afford a new, high-efficiency furnace without straining your budget. We’ll discuss all your options during the consultation so you can choose what works for your situation, spreading the cost into manageable monthly payments.
Manufacturers provide a warranty on the furnace itself, with terms that vary by brand and model. Extended or parts-coverage options are often available for added protection, and as a Lennox Premier Dealer we can walk you through what Lennox offers. On top of that, we provide a labor warranty on our installation and stand behind every job we complete. We’ll explain all warranty terms in plain language so you know exactly what’s covered and for how long.
A new, properly sized, high-efficiency furnace uses significantly less fuel than an aging, worn-out unit, which reduces your monthly heating costs. The exact savings depend on your old system’s efficiency, how you use heating, your home’s insulation, and the outdoor temperature swings Minnesota experiences. Most homeowners see a noticeable drop in heating costs with a modern high-efficiency system. Additional savings come from proper ductwork sealing, smart thermostat programming, and regular maintenance.
It’s well worth considering. A smart thermostat works seamlessly with your new furnace to optimize comfort and fuel use. You can control your heating from your phone, set custom schedules around your daily routine, and receive usage insights. By running your furnace only when you need heat, a smart thermostat helps you get maximum efficiency from your new equipment. We can install one during your furnace installation.
