An expert technician will test your furnace, verify and label its safety shutoffs, and give you honest, upfront prices on anything it needs, all behind a 100% money-back guarantee.

What Happens During Our Furnace Tune-Up

Our technicians work the furnace end to end, from combustion to airflow:

  • We assess all the burners for proper operation and inspect the heat exchanger surface.
  • We check the pilot assembly and the thermocouple for proper operation.
  • We inspect the gas valve and the flue pipe.
  • We evaluate the inducer and blower motors and lubricate pumps, bearings, and fans where applicable.
  • We tighten all electrical connections and test the safety switch and controls.
  • We check temperatures and pressures and verify airflow across the indoor coil and blower wheels.
  • We verify accurate operation of the thermostat, then test and label the emergency shutoffs.
  • We check the ductwork for leaks and check any humidifier or dehumidifier on the system.
  • We start the unit and test its full operation and cycle.

Why the Fall Visit Is Recommended

Furnace failures show up on the first cold mornings because that is when marginal components finally carry load. The thermocouple, pilot assembly, and safety switches our checklist tests are among the parts that keep a furnace lighting, and a problem found in the fall is a scheduled repair instead of a cold house in winter.

Safety is the deeper argument. The heat exchanger inspection and flue check verify that combustion gases stay separated from the air your family breathes, and the shutoff testing and labeling mean that in any future emergency, you can kill power and fuel to the system without hunting for the switches. It also keeps you on track with your manufacturer’s warranty requirements.

Why the Triangle Heats with Happy Home

Expert technicians who solve the issues others can’t run every Happy Home tune-up. The tune-up runs the furnace through a full start and cycle, so we see how it behaves as well as how it looks. Honest, upfront pricing and a 100% money-back guarantee come with the visit.

Online scheduling and 24/7 website chat are available, and if the tune-up finds a failing part, our gas furnace team handles the repair. We also service oil furnaces.

How Your Appointment Runs

The technician reviews last winter with you, services the furnace through the complete checklist, and runs it through a full cycle while watching how it starts, runs, and shuts down. Duct leaks and humidity equipment get checked in the same visit, since winter comfort in heating season depends on them too. You finish with a plain summary of the furnace’s condition and upfront prices on anything recommended.

Our Maintenance Plan

The VIP Club is our maintenance plan: a heating tune-up each fall, a cooling tune-up each spring, and an annual plumbing inspection, plus priority scheduling, reduced service fees, and savings on repairs.

FAQs

Do you service oil furnaces?

Yes. We service oil furnaces as well as gas furnaces.

What does a furnace tune-up cost?

The price depends on the type of furnace and the number of systems. Contact us with your equipment details, and we will give you the price. VIP Club members have a heating tune-up and a cooling tune-up each year in their plan.

Do you check my humidifier during a furnace tune-up?

Yes. If a humidifier or dehumidifier is tied to your system, the tune-up checks it, along with the ductwork for leaks, since both affect how comfortable the house feels in winter.

My furnace starts, runs briefly, and shuts off. Can the tune-up find out why?

Short cycling is a classic tune-up catch. Causes range from a dirty flame sensor to a clogged filter to a failing limit switch, and the full-cycle test in our visit lets the technician watch how the furnace behaves.

Why are the emergency shutoffs labelled?

Because in a gas or electrical emergency, seconds matter and you should not have to hunt for the switches. We test the shutoffs and make sure they are labeled so anyone in the house can cut power or fuel to the furnace immediately.
