Start With Your Home, Not the Equipment

Before picking a brand or fuel, match the system to your home. The right fit beats the hottest ad every time.

• Square footage and layout: Open plans and additions heat differently than closed rooms and older wings.
• Insulation and air sealing: Well‑insulated homes can use smaller equipment. Drafty homes need more capacity.
• Ductwork condition: Leaky or undersized ducts waste heat. Ductless options solve rooms that never warm up.
• Electrical and gas service: Available fuels, panel capacity, and venting guide what is practical.
• Lifestyle and comfort goals: Even room temps, fast warm‑up, quiet operation, smart controls.

In our market, we often start with a Manual J load calculation to size the system correctly. Oversized units short‑cycle and cost more to run. Undersized units struggle on those below‑zero nights we see a few times each winter.

“Furnace heat would not turn on. Kyle showed up when he said he would, diagnosed the problem and promptly fixed it. He also found other problems... explained what the problems were.”

Furnace Basics: Reliable, Fast Heat for Cold Snaps

A gas furnace heats air and pushes it through ducts. It is a strong choice if you already have natural gas and ductwork in good shape.

Pros

1. Powerful heat and quick recovery on very cold days.
2. Lower upfront cost than many heat pumps or boilers.
3. Simple maintenance with widely available parts.

Considerations

1. Efficiency rating is AFUE. High‑efficiency condensing models reach 95 percent or higher AFUE.
2. Requires safe venting and combustion air. Annual service protects performance and safety.
3. If your ducts are leaky or uninsulated, fix them to avoid wasted heat.

Good fit for: Most Bloomington–Normal homes with ducts and gas service, especially if you value fast warm‑up.

Heat Pump Basics: Efficient, All‑Electric Comfort With Cooling Built In

A modern air‑source heat pump moves heat rather than making it. It heats in winter and cools in summer. Options include ducted units and ductless mini‑splits for additions or hard‑to‑heat rooms.

Pros

1. One system for heating and cooling.
2. High efficiency, especially in spring and fall.
3. Ductless rooms get individual temperature control.

Considerations

1. Look for HSPF2 and SEER2 ratings. Cold‑climate models perform better in low temps.
2. In deep cold, supplemental heat or a dual‑fuel setup may be ideal.
3. Biannual tune‑ups are recommended because heat pumps often run year‑round in our area.

Good fit for: Homes aiming to reduce gas use, improve efficiency, or solve comfort issues without new ducts.

“The service was professional, thorough, and completely hassle‑free. Kyle arrived early and spent over an hour on a detailed inspection of our 10‑year‑old heat pump system. No pressure sales, just honest feedback.”

Boiler Basics: Even, Quiet Heat Through Radiators or In‑Floor

Boilers heat water and move it through radiators or radiant floors. The comfort is steady, quiet, and not as dry as forced air.

Pros

1. Gentle, even warmth with very quiet operation.
2. Zoning is easy with separate loops.
3. Great match for radiant floors and older homes with existing radiators.

Considerations

1. Efficiency is measured in AFUE for gas or oil boilers.
2. Upfront cost can be higher than a furnace. Piping condition matters.
3. No built‑in cooling. You will still need an AC or heat pump for summer.

Good fit for: Homes that already have radiators or want radiant floor comfort in kitchens, basements, and bathrooms.

Dual‑Fuel: The Best of Furnace and Heat Pump Together

A dual‑fuel system pairs an electric heat pump with a high‑efficiency gas furnace. The heat pump handles mild to moderate cold. The furnace takes over when temps drop.

Why homeowners choose it

1. Efficiency most of the season with strong heat during arctic blasts.
2. Lower operating cost than furnace‑only in shoulder months.
3. Redundancy. If one component needs service, the other can cover.

Best for: Bloomington–Normal families seeking comfort and savings without sacrificing performance in January cold.

Ducted vs. Ductless: Solving Real‑World Comfort Problems

• Hot‑and‑cold rooms: A ductless head in a bonus room or sunroom fixes chronic comfort issues without tearing into walls.
• Additions and finished basements: Mini‑splits avoid expensive duct extensions.
• Whole‑home solutions: Ducted heat pumps or furnaces make sense if your ducts are sound. If not, repair or seal them first.

Tip: We test static pressure and inspect ducts for size and leakage. Correct airflow protects your new system and your energy bill.

Fuel and Utility Considerations in Central Illinois

• Natural gas: Widely available, often cost‑effective in winter. Great for furnaces and boilers.
• Electricity: Heat pumps shine in spring and fall and can be paired with dual‑fuel for cold snaps.
• Propane or oil: Consider modern high‑efficiency furnaces or boilers if gas is not available.

Local insight: In Bloomington, Normal, and nearby towns like Le Roy, Heyworth, and Lexington, wind chills can drop fast. Plan capacity and backup heat to cover those swings.

Sizing, Efficiency, and Total Cost of Ownership

Right‑sized equipment saves money and avoids comfort complaints.

• Sizing: Request a Manual J load. It accounts for insulation, windows, and infiltration, not just square footage.
• Efficiency labels:
• 1. AFUE for furnaces and boilers. Higher is better.
  2. HSPF2 and SEER2 for heat pumps. Compare across similar sizes and brands.
• Lifetime cost: Add purchase price, installation, maintenance, and energy use. The cheapest bid can be the most expensive to own if it is oversized or installed poorly.

Hard fact: Our team performs biannual heat pump tune‑ups in spring and fall and recommends the same for year‑round systems. Routine tune‑ups can catch small issues before they become costly repairs.

Controls, Filtration, and Indoor Air Quality

Comfort is more than temperature.

• Smart thermostats: Programmable schedules, remote control, and usage reports help trim bills.
• Zoning: Multi‑zone setups reduce hot and cold spots, especially in two‑story homes.
• Filtration and humidity: High‑MERV filters and humidifiers improve comfort and air quality. We calibrate thermostats and can activate built‑in humidifier features during service.

What a Proper Installation Looks Like

From the first visit to the final walkthrough, process matters.

1. Home assessment: Measure rooms, inspect insulation and ducts, and check electrical or gas service.
2. Transparent estimate: Clear scope and pricing before work starts. No surprises.
3. Professional install: Safe venting, sealed ducts, correct line‑sets, and code‑compliant wiring.
4. Commissioning: Verify airflow, refrigerant charge, combustion, and controls.
5. Owner training: We walk you through the thermostat, filter changes, and maintenance schedule.

Hard fact: Summers has served local homeowners since 1969 with licensed, drug‑tested, and background‑checked technicians. We offer price‑match guarantees and strong labor warranties on installed systems.

“Eric and Josh replaced our furnace today. They were very proficient and professional executing the install... answered them all and were very courteous throughout the process.”

Maintenance Plans That Protect Your Warranty and Comfort

Heat pumps that run year‑round benefit from service twice a year. We recommend early spring and early fall. For furnaces and boilers, schedule annual service before the first cold snap.

What our tune‑ups include

• Clean outdoor and indoor coils, and clear debris.
• Check refrigerant levels and scan for leaks.
• Calibrate thermostats for accurate control.
• Inspect wiring and tighten connections.
• Lubricate moving parts.
• Flush condensate drains.
• Test safety controls and reversing valve operation on heat pumps.
• Replace or clean air filters for healthy airflow.

Value of a plan

1. Priority scheduling before peak season.
2. Helpful reminders so you never miss service.
3. Lower energy use and fewer surprise breakdowns.

“Extensive examination of furnace and even changed a dirty filter. Went over everything with me thoroughly.”

Which System Is Best For Your House? A Quick Decision Guide

• You have gas, good ducts, and want fast heat: Choose a high‑efficiency furnace.
• You want high efficiency and built‑in cooling: Choose a heat pump. Add dual‑fuel for extreme cold.
• You have radiators or want silent, even warmth: Choose a boiler or radiant floor system.
• You have rooms that never warm up: Add a ductless mini‑split to target problem areas.

Next step: Ask for a load calculation and a side‑by‑side proposal that compares upfront price, expected operating costs, and warranty for each option.

Red Flags When Comparing Bids

• No load calculation and only a square‑footage guess.
• Oversized equipment sold as an upgrade.
• Missing permits or unclear venting and electrical details.
• Quotes that skip commissioning steps or owner training.
• Vague warranty language or no mention of manufacturer coverage.

Frequently Asked Questions

How do I know what size heating system I need?

Ask for a Manual J load calculation. It sizes equipment based on insulation, windows, air leakage, and layout, not just square footage.

Is a heat pump enough for Central Illinois winters?

Yes for many homes, especially with a cold‑climate model. For the coldest snaps, pair it with a gas furnace in a dual‑fuel system.

What efficiency should I look for in a furnace?

Choose a high‑efficiency condensing furnace around 95 percent AFUE or higher. Also confirm proper venting and commissioning.

Do I need ducts in good shape for a new system?

Yes. Leaky or undersized ducts waste heat and shorten equipment life. Seal and size ducts before or during replacement.

How often should I service my heating system?

Heat pumps need biannual tune‑ups in spring and fall. Furnaces and boilers need annual service before the first cold snap.

In Summary

The best heating system for your house depends on your home, fuel options, and comfort goals. In Bloomington–Normal, many owners choose high‑efficiency furnaces, cold‑climate heat pumps, or a dual‑fuel combo for the perfect balance. Ready for clear answers and upfront pricing?
