Rheem Furnace

Warming Up to Change

When Martha bought her cozy one-bedroom in the hills of Duvall, the realtor had described it as “full of character.” And it was—original hardwood floors, a brick fireplace, and a furnace that had likely been installed when disco was still popular.

The old Trane furnace had served faithfully for decades. It groaned to life each winter with the perseverance of an old workhorse, keeping her small home just warm enough to avoid frostbite. But in recent years, Martha had noticed its age. Heating bills climbed steadily, and the unit started cutting out during the coldest nights. The last straw came one January morning when she woke up to a 52-degree bedroom and frost on the inside of the windows.

After one final, sputtering attempt to turn on, the furnace gave up. Martha, wrapped in two quilts and sipping her third cup of tea, finally admitted it was time.

She called in Fast Heating and Air for a service call, who confirmed what she already suspected: the old Trane was inefficient and nearing the end of its life. “You got more years out of this thing than most people get from a dog,” the technician said with a chuckle. “But it’s time.”

She considered her options. A different brand? A cheaper model? But in the end, she went with what had worked. Trane had built a reputation for reliability, and after forty years, she figured they’d only gotten better.

Two weeks later, the new Trane furnace was installed—sleek, quiet, and efficient. The technician showed her how to adjust the smart thermostat from her phone, which blew her mind a little. “No more twisting dials and crossing your fingers,” he said.

That night, Martha sat on her couch with a book, her feet warm against the hardwood. The furnace hummed quietly in the background, a gentle reminder that her home had just stepped into the 21st century. For the first time in years, she didn’t dread the rest of winter.

She smiled, thinking about the old furnace—loyal to the end. But as the warmth filled the house, Martha knew she’d made the right choice. Some things are worth updating, especially when comfort is on the line.

Key Signs You Should Replace Your Household Furnace

It’s 15–20 Years Old. Most furnaces last 15–20 years. If yours is getting up there in age, it’s likely losing efficiency and may be nearing the end of its lifespan—even if it’s still running.

Rising Energy Bills

 An older or failing furnace often runs longer and harder to heat your home, leading to higher utility costs.

Frequent Repairs

 If you’re calling a technician every season (or more), the repair bills can quickly add up. A new unit might save money in the long run.

Uneven Heating

Cold spots or inconsistent temperatures can indicate your furnace is no longer distributing heat properly.

Short Cycling

 Is your furnace turning on and off more often than it used to? This could signal mechanical issues or failing components.

Strange Noises

Banging, popping, rattling, or squealing are signs of wear—and potential failure.

Poor Air Quality or Excessive Dust

An older furnace may struggle to filter air effectively, leading to dust, dry air, or increased allergy symptoms.

Yellow Pilot Light (Gas Furnace)

A yellow or flickering pilot light may indicate carbon monoxide or combustion issues—this requires immediate attention.

Struggles to Keep Up

If your home still feels cold even with the furnace running, or it takes longer to heat, the system may be losing efficiency.

What will our pros do for new Trane furnace purchase?

Initial Consultation & Home Inspection

The technician starts with a walkthrough of your home to understand its layout, size, and insulation quality. They'll ask questions about your current heating performance, any comfort issues (cold rooms, drafts, high bills), and your preferences for energy efficiency or smart technology

Load Calculation (Manual J)

To ensure proper sizing, the technician performs a Manual J load calculation. This includes the square footage of your home, window types and insulation levels, ceiling height, number of occupants, and local climate data. This calculation helps avoid installing a furnace that’s too big (wastes energy) or too small (can’t keep up).

Ductwork Evaluation

They inspect your existing ductwork for leaks or gaps, sizing and airflow capability, and cleanliness or obstructions.

Reviewing System Options

Based on the assessment, the technician will recommend furnace models (standard vs. high-efficiency Trane models), discuss features like variable-speed blowers or smart thermostats, and present costs, rebate options, and warranties.

Energy Efficiency & Budget Match

For your Trane furnace, the HVAC technician will guide you on energy efficiency ratings (AFUE), expected utility savings, return on investment, and compatibility with future HVAC upgrades

Final Proposal & Scheduling

Once you've selected a system, the technician provides a detailed estimate, schedules installation, and explains what to expect before, during, and after the install.

What will our pros do for new Trane furnace service?

Servicing a Trane home furnace involves a step-by-step inspection and tune-up to ensure it’s running safely, efficiently, and reliably—especially before the heating season kicks in. Here’s how our professional HVAC technician typically handles it:

Safety First

Before starting, the technician will shut off power and gas to the furnace, follow Trane manufacturer guidelines for safety and access, and wear protective gear and follow proper ventilation protocols.

Clean Interior Components

Dust and debris can affect performance. The tech will clean the burners for even flame distribution, vacuum out the blower compartment, remove and clean the blower motor and fan blades if needed, and check and clean the flame sensor and ignitor.

Inspect for Wear and Damage

The technician will carefully inspect the heat exchanger for cracks or corrosion (a critical safety check), burners for buildup or misalignment, wiring and connections for fraying, corrosion, or loose fittings, and the belts and moving parts for wear and proper tension.

Air Filter Check

A clogged filter can reduce efficiency and strain the system. The tech will check the air filter, and clean or replace it depending on condition

Test Thermostat and Controls

Our HVAC technician will test your thermostat to ensure it communicates properly with the furnace, the cycle timing is correct (on/off intervals), and the settings are calibrated correctly for comfort and efficiency

Run System Diagnostics

With everything clean and inspected, the technician will restart the system, monitor startup behavior, flame pattern, and blower operation, check gas pressure, voltage readings, and amp draws, and listen for abnormal noises or vibration
