Types of Furnaces We Install
Minnesota winters demand dependable, efficient heat. We install every common furnace type - gas, propane, electric, and oil - and then layer in the efficiency and comfort features that keep your home warm, quiet, and affordable all season.
Natural Gas
The most common path for dependable, economical heat in long cold seasons. We typically recommend high-efficiency condensing models for lower fuel use. Key details we plan for: safe PVC vent placement above typical snow lines and freeze-safe condensate routing to prevent icing.
Propane (LP)
Ideal where utility gas isn’t available. Offers gas-like comfort with on-site tank storage. We design for tank access, code clearances, and sealed-combustion safety so deliveries and winter operation stay simple and reliable.
Electric
No flue required and simpler placement, useful where gas or LP isn’t an option or in certain attached homes. Expect higher monthly costs across long heating seasons; works best with an ECM variable-speed blower, tight ductwork, and smart controls to keep comfort steady.
Oil
Still present in older housing stock and capable of high BTU output. Requires regular service (tank, filter, nozzle) and proper venting. If you’re considering a conversion to natural gas, we’ll map the steps, timeline, and total cost of ownership so you can decide confidently.
Pro tip: For efficiency on mild days and strength in deep cold, a dual-fuel setup (heat pump + gas furnace) isn’t a separate type, but it can trim annual costs with the right balance point and controls.
How We Match the Type of Furnace to Your Home
1. Compact mechanical rooms and older ductwork. Best fit: gas or LP high-efficiency condensing furnace (short-cabinet or side-return). Comfort features: two-stage or modulating heat, ECM variable-speed blower, sealed combustion. Design details: vent terminations set above typical snow lines and freeze-safe condensate routing. Why it works: fits tight spaces safely, reduces noise, and smooths room-to-room temperatures.
2. Multi-level or larger footprints. Best fit: gas or LP modulating condensing furnace, or dual-fuel (heat pump + gas) for shoulder-season savings. Comfort features: modulating burner with ECM airflow, zoning (two or more zones), added return paths. Design details: balance returns per level and quiet continuous fan profiles for even mixing. Why it works: eliminates cold rooms and stacking, cuts noise, and lowers annual energy use.
3. Attached homes or shared-wall properties. Best fit: gas or LP sealed-combustion condensing, or electric where combustion venting isn’t feasible. Comfort features: quiet start/stop blower profiles and sealed intake/exhaust for clean make-up air. Design details: sidewall venting planned for clearances and snow berms, plus vibration-damping bases if on framing. Why it works: controls sound and back-draft risk while keeping operation discreet and safe.
4. Homes without natural-gas service. Best fit: propane (LP) furnace or dual-fuel; electric only with adequate panel capacity and cost awareness. Comfort features: two-stage or modulating heat and smart controls to optimize heat-pump balance point. Design details: tank siting and line routing for winter access, plus electrical verification for dual-fuel or electric paths. Why it works: delivers gas-like comfort now, with the option to trim annual costs in milder weather.
5. Tight or recently weatherized homes. Best fit: condensing, sealed-combustion furnace. Comfort features: ECM blower at low continuous speed, high-MERV media filtration, whole-home humidifier. Design details: confirm combustion air and set winter humidity targets to protect finishes and furnishings. Why it works: airtight envelopes benefit from sealed combustion and gentle circulation for even temps and better air quality.
6. Budget-first replacement with an upgrade path. Best fit: 95%+ AFUE condensing furnace (Essential package). Comfort features: two-stage burner with ECM blower now, pre-wire and thermostat ready for future zoning or dual-fuel. Design details: present Good/Better/Best with StraightForward Pricing and monthly payment options. Why it works: delivers meaningful comfort and efficiency today while keeping add-ons simple later.
Once we’ve matched the furnace to your home and climate, the next step is simple. We’ll come out, verify the load and duct health, map a clean vent and condensate path, and show you clear Good/Better/Best options with monthly payment choices. Your comfort is protected by our On-Time Guarantee and 100% Satisfaction Guarantee, and we’ll help you capture any eligible rebates so you don’t leave money on the table.
Installation vs. Replacement: What the Process Looks Like
Furnace Installation
- Start from scratch: we calculate the heating load, select the right furnace, and design the system for your home.
- Ductwork: new ducts and returns are laid out and installed if the home doesn’t already have a central heating system.
- Connections: fresh venting, condensate lines, and gas or electrical hookups are put in place.
- Timeline: because the infrastructure is new, installation requires more planning, coordination, and inspections before the system is commissioned.
In short: installation is about building a complete heating system from the ground up.
Furnace Replacement
- Remove old equipment: the existing furnace is carefully disconnected, hauled away, and the space prepared for the new system.
- Ductwork: existing ducts are inspected; if they’re in good shape, we seal and adjust them for airflow. If they’re undersized, leaky, or damaged, we recommend partial replacement or rework.
- Connections: venting, gas lines, and electrical components are updated or replaced to ensure compatibility and safety with modern equipment.
- Timeline: with most of the infrastructure already in place, replacement is generally completed in a single day.
In short: replacement means removing what’s old, reusing what still works, and upgrading everything else to fit the new furnace.
Whichever path applies, we finish the same way: full commissioning with documented safety readings, a clean workspace, and a clear walkthrough of your controls. You’ll have StraightForward Pricing in writing before we begin, permits and inspections handled, and options for financing and any eligible rebates.

Frequently Asked Questions
How long does a furnace replacement take? +
Most replacements are completed in a single day. We remove the old unit, set the new furnace, update venting, gas, and electrical as needed, seal and adjust ducts, commission the system, and clean the work area.
Will I be without heat during replacement? +
Yes, only during the work window. We schedule efficiently, bring all materials, and commission the system the same day whenever possible.
Do you reuse my existing ductwork or replace it? +
If ducts are sound, we reuse them and improve performance by sealing leaks, adding returns, and balancing airflow. If sections are undersized, damaged, or leaky beyond repair, we replace or rework only what's necessary.
What's different about a first-time installation? +
We design the entire system - load calculations, equipment location, new trunks, branches, and returns, safe vent and condensate routing, and new gas or electrical connections. It's a larger, planned project with inspections.
Are permits and inspections included? +
Yes. We handle permits and coordinate required inspections. Your install meets current mechanical, electrical, and fuel-gas codes.
Do you help with financing and rebates? +
Yes. We provide StraightForward Pricing in writing, offer monthly payment options with approved credit, and help identify and claim any eligible local incentives for qualifying equipment.
What should I do to prepare for installation day? +
Clear a path to the mechanical area, move fragile items, and secure pets. We protect floors, bring runners and drop cloths, and haul away the old equipment.
What warranties and guarantees come with my new furnace? +
You'll receive manufacturer parts coverage and our workmanship warranty, plus our On-Time Guarantee and 100% Satisfaction Guarantee. We document commissioning readings so you know it's set up correctly from day one.
