When It’s Time to Replace Your Furnace

Here are the signs Kannapolis-area homeowners should watch for:

Your furnace is 15-20+ years old

Most furnaces last 15-20 years with proper maintenance. Systems nearing the end of that range are less efficient, more repair-prone, and more likely to fail during the coldest nights.

If you’ve spent more than half the cost of a new furnace on repairs in the last two years, replacement is the smarter financial decision.

Your energy bills keep rising

Older furnaces operate at 60-80% AFUE efficiency. A new high-efficiency furnace rated at 95-98% AFUE delivers dramatically lower heating costs.

Cracked heat exchanger

A cracked heat exchanger is expensive to repair and a serious carbon monoxide safety risk. On furnaces over 12 years old, replacement almost always makes more financial sense.

Uneven heating

If some rooms stay cold despite the furnace running, the system may be failing or improperly sized. A properly sized new furnace solves this.

System uses R-22 refrigerant

If your heating system includes a heat pump using R-22 refrigerant, the entire system should be evaluated for replacement since R-22 is no longer manufactured.

Furnace Systems We Install

We install a full range of residential heating systems to fit every home type and budget:

Single-Stage Gas Furnace (80% AFUE) — The most affordable option. Runs at full capacity whenever it’s on. A solid choice for budget-conscious homeowners. Vents through standard metal flue pipe.

Two-Stage Gas Furnace (95-96% AFUE) — Runs at a lower, quieter setting most of the time and ramps up to full capacity only during extreme cold. Better energy efficiency and more consistent comfort. Uses PVC venting.

Variable-Speed Modulating Gas Furnace (97-98% AFUE) — The highest efficiency available. Continuously adjusts output to match your home’s heating demand, providing the most even temperatures and lowest energy bills. Virtually silent operation.

Electric Furnace — Lower equipment cost than gas, and a good option in areas without natural gas service. Electric furnaces have higher operating costs but require no combustion venting and have fewer safety concerns.

Dual-Fuel Systems — Pairs a heat pump with a gas furnace for the most efficient year-round heating. The heat pump handles mild days, and the furnace takes over during the coldest temperatures. Ideal for North Carolina’s variable winters.

Our Installation Process

1. Free in-home estimate. We visit your home, assess your current system, measure your space, evaluate your ductwork, and discuss your comfort needs and budget. We provide a detailed written quote — not a ballpark number.

2. Right-sizing your system. We perform a heat load calculation that factors in your home’s square footage, insulation levels, window count, ceiling height, and the Kannapolis-area climate. Proper sizing is essential.

3. Professional installation. Our technicians install your new furnace according to manufacturer specifications and local building codes. We handle everything — gas connections, venting, electrical wiring, thermostat setup, and ductwork modifications if needed.

4. Testing and walkthrough. After installation, we run your new furnace through a complete heating cycle, verify gas pressure, check for leaks, test carbon monoxide levels, and measure airflow at every register.

5. Registration and warranty. We register your equipment with the manufacturer to activate the full warranty and provide you with all documentation.

Frequently Asked Questions — Furnace Installation — AC Repair

How long does furnace installation take?

Most standard furnace replacements are completed in one day, typically 4-8 hours. If significant ductwork modifications or venting changes are needed, it may extend to two days.

Do I need a permit for a new furnace in Kannapolis?

Yes. Cabarrus County requires a mechanical permit for new furnace installations. We handle all permit paperwork and scheduling as part of our installation — you don’t need to worry about it.

What brands do you install?

We install Carrier, Lennox, and Goodman furnaces. Each brand offers options at different price points and efficiency levels. We recommend the best fit based on your home, budget, and comfort priorities.

Not necessarily, but there are advantages. If both systems are aging, replacing them together ensures they’re properly matched for optimal efficiency and often costs less than two separate installations. If your AC is still in good shape, replacing just the furnace is fine.

What’s the difference between single-stage and variable-speed furnaces?

A single-stage furnace runs at full blast or not at all. A variable-speed furnace continuously adjusts its output to match your home’s heating needs, providing more even temperatures, lower noise, and better energy efficiency. The tradeoff is a higher upfront cost, but lower monthly operating costs.

What AFUE rating should I choose?

For most Kannapolis and Concord homeowners, a 95-96% AFUE furnace is the sweet spot — good balance of upfront cost and energy savings. If you plan to stay in your home long-term, 97-98% AFUE delivers the lowest heating bills.
