Start With Signs You Need a Furnace Replacement

Most gas furnaces last 15 to 20 years with regular maintenance. Replacement is worth considering if you see these patterns:

• Frequent repairs or a cracked heat exchanger
• Uneven rooms, rising gas or electric bills, short cycling
• Excess dust or dry air, louder operation than before
• Safety concerns like repeated flame rollout or tripping limits

Homeowners around Huntington and Bluffton often notice the first clue on utility bills as winter sets in. If repairs approach 25 to 40 percent of a new unit, replacement usually pays off within a few seasons.

Sizing: Get the BTUs Right

The best furnace is sized to your home, not just your square footage. Oversized units short cycle and waste energy. Undersized units run constantly and still leave rooms cold.

What goes into proper sizing:

1. Manual J load calculation: square footage, insulation, windows, orientation, and air leakage all matter.
2. Ductwork and static pressure: your ducts must handle the airflow your new furnace delivers.
3. Local climate: Northeast Indiana’s long freezes increase heating load versus milder regions.

Ask for a written load calculation and a duct assessment. Correct sizing protects comfort, efficiency, and equipment life.

Efficiency: AFUE and What It Really Means

AFUE stands for Annual Fuel Utilization Efficiency. It shows how much of your fuel becomes heat for your home.

• 80 percent AFUE: standard venting, lower upfront cost
• 90 to 95 percent AFUE: condensing furnaces, sealed combustion, PVC venting
• 96 to 98 percent AFUE: top tier efficiency, excellent for cold climates

Higher AFUE models often qualify for utility rebates and can cut winter gas use significantly. Balance the savings with your time in the home, fuel prices, and the cost of venting changes.

Staging: Single, Two‑Stage, or Modulating

How a furnace delivers heat affects comfort and noise.

• Single‑stage: full on or off. Lowest cost, more temperature swings.
• Two‑stage: low fire most of the time, high fire on cold snaps. Quieter, better comfort.
• Modulating: adjusts in small increments to match the exact load. Most consistent comfort and often the highest efficiency.

If you have hot and cold spots or want quieter operation, two‑stage or modulating paired with a variable‑speed blower is a strong upgrade.

Blower Motors: PSC vs ECM

Your blower moves air across the heat exchanger and through your ducts.

• PSC motors: basic and affordable, higher energy use
• ECM variable‑speed motors: better airflow control, lower energy use, improved humidity control with compatible thermostats

ECM motors can trim electric use during long heating seasons and help solve airflow issues in rooms at the end of the duct runs.

Venting, Gas Line, and Combustion Air

Your install may need updates beyond the furnace.

• Venting: 90 percent-plus furnaces require PVC venting and proper condensate drainage.
• Gas supply: line sizing and regulator checks ensure safe, steady fuel delivery.
• Combustion air: sealed combustion models draw air from outdoors, improving indoor air quality and safety.

A professional site check confirms these details before installation day so there are no surprises.

Ductwork and Filtration

New equipment cannot overcome poor duct design. Before replacement, evaluate:

• Return air size and location
• Supply runs feeding problem rooms
• Static pressure and leakage

Simple changes like adding a return or sealing accessible seams can unlock comfort. For filtration, a media cabinet with a 4 to 5 inch filter captures more dust with less airflow restriction than 1 inch filters.

Thermostats and Controls

Modern controls add comfort and savings.

• Programmable or smart thermostats with learning features
• Remote monitoring and alerts
• Advanced staging control for two‑stage or modulating units

Confirm thermostat compatibility with your selected furnace and any add‑ons like humidifiers or air cleaners.

Indoor Air Quality Add‑Ons

Winter air can be dry and stale. Consider these paired solutions:

• Whole‑home humidifier to protect wood floors and comfort
• High‑MERV media filter or cabinet
• UV or high‑efficiency air purifier for households with allergies

Match add‑ons to your goals. A humidifier is the most common comfort upgrade for Northeast Indiana homes.

What to Expect on Installation Day

A smooth install follows a clear plan.

1. Permits and safety: code‑compliant venting, gas checks, and combustion testing.
2. Removal: safe handling and disposal of the old unit.
3. Set and seal: precise leveling, gasketing, and duct transitions.
4. Commissioning: gas pressure, temperature rise, airflow verification, and control setup.
5. Clean‑up: sweep and protect work areas, review thermostat and filter maintenance.

Fully stocked trucks help avoid delays and return trips. You should receive a startup report and warranty information when the job is complete.

Warranties and Guarantees That Matter

Look for strong protection in writing.

• One‑year labor and manufacturer warranty on HVAC equipment and services from our team
• Manufacturer parts coverage that can extend longer depending on model registration
• Maintenance agreement benefits like zero overtime charges and prioritized status

Ask how to keep warranties valid with annual tune‑ups and filter changes.

Budget, Financing, and Total Cost

The furnace price is only part of the story. Consider:

• Equipment tier and AFUE rating
• Venting changes and condensate pump if needed
• Ductwork or gas line updates
• Thermostat and indoor air quality options
• Labor, permits, and disposal

Flexible financing and transparent, upfront pricing make planning easier. We provide options so you can compare good, better, and best without pressure.

Rebates and Energy Savings

High‑efficiency furnaces often qualify for utility rebates or seasonal promotions. Keep these steps in mind:

1. Confirm eligibility before installation.
2. Save model and serial numbers and installation documents.
3. Submit rebate forms promptly.

Your advisor can estimate annual fuel savings based on your current bills and the AFUE upgrade.

Maintenance After Replacement

Protect your investment with simple habits:

• Change 1 inch filters every 1 to 3 months, media filters every 6 to 12 months
• Keep supply and return vents unblocked
• Schedule annual furnace tune‑ups before the first cold snap

Our $69 furnace tune‑up includes a No Breakdown Guarantee during the season, which adds peace of mind when temperatures drop below freezing.

Safety First

A safe system starts with expert installation and continues with monitoring.

• Install a carbon monoxide detector on each level
• Keep combustible storage away from the furnace
• Call for service if you smell gas or see persistent ignition failures

Our 24/7 emergency heating service means you can get help anytime during a cold night.
