Start With Clear Goals: Comfort, Safety, and Savings

Replacing a gas furnace is not just swapping a box. It is your chance to improve comfort room by room, cut energy waste, and lock in safe, reliable heat. Begin by writing three goals. For most Peru homeowners, these are lower energy bills, fewer repairs, and more even heat. With clear goals, every choice becomes easier.

Consider your current pain points. Do you have cold rooms at the ends of your duct runs? Does the furnace roar on, then off, leaving you hot then cold? Do you smell combustion byproducts or see rust around the flue? Each issue points to a specific feature or task in your replacement plan. A smart plan pairs the right furnace with the right duct fixes and controls.

“We received our new furnace today, very professional company and installers, Nick and Gabe did a fantastic job explaining our new system and were very polite!”

Know When Replacement Beats Repair

Generally, it is time to replace when the repair cost is over 40 percent of a new system, the heat exchanger is cracked, or the unit is 15 to 20 years old with rising bills. If you have frequent lockouts, failed igniters, or a blower motor that keeps quitting, weigh the age and efficiency of the unit before throwing good money after bad.

Indiana winters put real demand on equipment. If your furnace cannot maintain setpoint on the coldest nights or runs constantly, it may be undersized or simply tired. A replacement restores performance and unlocks higher AFUE ratings that reduce gas use.

“Dylan installed my new furnace. Very professional and friendly. He explained everything, protected the floors, and cleaned up great. You would never guess a furnace had been replaced.”

Right-Size the Furnace for Peru Weather

Proper sizing prevents short cycling, noise, drafts, and premature wear. Your contractor should complete a Manual J load calculation, not a rule of thumb. The calculation considers home size, insulation, window type, orientation, and air leakage. In older Peru and Logansport homes, air sealing and duct fixes often allow a smaller, quieter furnace that costs less to run.

Ask to see the load result in BTUs, then match it to furnace output, not input. Output is input multiplied by efficiency. For example, a 100,000 BTU input furnace at 95 percent AFUE delivers about 95,000 BTU output. When in doubt, choose the smaller model within the safe range. Slightly smaller units tend to run longer and more evenly.

AFUE Efficiency: What the Numbers Really Mean

AFUE is the percentage of fuel energy that becomes heat for your home over a season. Higher AFUE equals lower gas bills. Many replacement furnaces today range from 80 percent to 98 percent AFUE.

• 80 percent AFUE: Vented to a chimney, lower upfront cost, higher operating cost.
• 90 to 95 percent AFUE: Condensing, uses PVC venting, strong balance of cost and savings.
• 96 to 98 percent AFUE: Top-tier efficiency with sealed combustion.

Energy Star notes that qualified gas furnaces in the U.S. North region meet a 95 percent AFUE or higher. In Peru’s cold snaps, that level can make a real dent in winter bills while improving comfort and safety with sealed combustion.

Staging: Single, Two-Stage, or Modulating

How the furnace delivers heat matters as much as AFUE.

• Single-stage: On or off at full fire. Lowest price, most noticeable swings.
• Two-stage: Low and high fire. Quieter, more even heat, better humidity control.
• Modulating: Many small steps between low and high. Best comfort and quiet, highest cost.

For most Miami County homes, two-stage is a sweet spot. It runs longer on low, smoothing temperatures across rooms and reducing noise. If you have big swings, drafts near registers, or finished spaces over garages, consider modulating with a matched variable-speed blower.

Blower Motors: PSC vs ECM

Your blower pushes conditioned air through the ducts. There are two main choices.

• PSC (permanent split capacitor): Lower upfront cost, higher electricity use, fewer control options.
• ECM (electronically commutated motor): More efficient, variable speeds, quieter, better airflow control.

An ECM blower paired with two-stage or modulating heat often delivers the biggest comfort upgrade. It mixes air more gently, keeps temperatures even, and can support better filtration without a big power penalty.

Venting, Combustion Air, and Safety

High-efficiency condensing furnaces use PVC intake and exhaust. They need proper slope for condensate drainage and correct termination clearances outside. Standard 80 percent units often reuse the chimney, but liners may be needed to keep flue gases hot enough to draft.

Your installer should verify combustion air, test for spillage, and set gas pressure with a manometer. A combustion analysis after startup confirms safe oxygen and carbon monoxide levels. Add low-level CO monitoring for whole-home protection. Safety checks are not optional when dealing with gas, flame, and exhaust.

Ductwork and Airflow: Fix the Bottlenecks

A new furnace cannot fix bad ducts. If your return is undersized or supply trunks neck down, you will get noise and poor heat. Ask for:

1. Static pressure test before and after.
2. Measured airflow targets that match equipment specs.
3. Sealing and balancing for even room temperatures.

Common upgrades include adding a return to the master suite, upsizing restrictive transitions, and sealing joints with mastic. In older Peru and Rochester homes, these simple changes can transform comfort.

Filtration, Humidity, and Indoor Air Quality

Your furnace replacement is the ideal time to upgrade the filter rack and IAQ accessories.

• MERV 11 to 13 media filters catch fine dust and reduce coil fouling.
• Whole-home humidifiers protect hardwoods and help you feel warmer at lower setpoints.
• Dehumidifiers can tie into the system to keep basements drier in shoulder seasons.

Ask for a sealed filter cabinet and a bypass or steam humidifier sized to your load. Better IAQ extends equipment life and helps sensitive family members breathe easier.

Thermostats and Controls that Pay You Back

Smart thermostats with learning or sensor-based control smooth out hot and cold spots. Zoning can help multistory homes by splitting floors into separate control areas. If you install a two-stage or modulating unit, choose a thermostat that can command both stages, not just on and off.

Controls also affect eligibility for utility rebates. Many programs require a qualifying smart thermostat and minimum AFUE. Your contractor should handle paperwork and commissioning so you claim every incentive available.

Warranties, Guarantees, and What They Really Cover

Not all warranties are equal. Look for two layers:

1. Manufacturer warranties on heat exchangers and parts.
2. Contractor workmanship and labor coverage.

Summers offers a one-year warranty on all parts and labor for heating, cooling, and ventilation services. That is in writing. You also get our price-match promise. If a competitor undercuts us on a comparable install, we will match or beat it. Ask us for details and exclusions, and always save your paperwork.

Budgeting and Financing Without Compromise

A high-efficiency, two-stage furnace with an ECM blower usually returns its premium through lower bills and fewer repairs. To keep cash flow smooth, ask about financing options and membership programs that include maintenance discounts. Spreading payments over time lets you choose the right system now rather than settling for the cheapest box.

Summers regularly features seasonal specials and 0 percent promotional financing options on approved credit. We can review offers during your estimate and help you stack eligible rebates where allowed.

Choosing the Right Installer: A Short Checklist

The best equipment fails with sloppy install. Use this checklist when you compare quotes.

1. Load calculation provided and shared.
2. Detailed scope includes venting, gas line testing, and duct corrections.
3. Static pressure and combustion analysis documented.
4. Permits and inspections handled.
5. Warranty terms in writing and startup form left with you.

Local experience matters. Our team has served Peru, Logansport, Rochester, and nearby communities since 1969. We know how older Miami County homes are built and what fixes provide the biggest comfort gain for the dollar.

What to Expect on Installation Day

Most replacements complete in one day. Here is the typical flow.

1. Protect floors and pathways, then remove the old unit.
2. Set the new furnace and adapt the plenum and transitions.
3. Connect gas, venting, condensate, and electrical.
4. Pressure test the gas line and check for leaks.
5. Program the thermostat and verify staging.
6. Perform combustion analysis and static pressure testing.
7. Clean up and walk you through operation and maintenance.

You should receive model and serial numbers, warranty registration details, and a written startup report. Keep these with your records.

After the Install: Maintenance That Protects Your Investment

Even the best furnace needs seasonal care. A precision tune-up and cleaning keeps efficiency high, reduces breakdown risk, and validates many manufacturer warranties.

• Replace filters on schedule.
• Keep clearances around the furnace.
• Schedule annual heating maintenance before cold weather.

Members of our maintenance program get automatic scheduling, priority service, and no overtime fees. Regular checkups catch failing igniters, dirty flame sensors, and weak draft before they cause a no-heat call.
