Furnace Repair, Installation and Fall Tune-Ups
for North Texas Homes

North Texas winters are generally mild compared to northern states, but the sudden cold fronts and freezing temperatures are exactly what expose a weak furnace. A system that coasts through November can fail on the first hard freeze in January. Graco Heating & Air has installed, repaired and serviced furnaces across the region for over 30 years as Armstrong ProTeam dealers, licensed under TX License #TACLA00017212E.

Heating Built for This Climate

Why North Texas Furnaces Are Different

Heating needs here do not look like Minnesota, and equipment specified for a northern winter is the wrong answer for a Lewisville home. Four regional factors drive every recommendation we make.

Short, Sharp Heating Season

Heating demand concentrates from December through February. A furnace that sits idle nine months of the year needs a fall inspection before it is asked to work.

Occasional Extreme Cold Snaps

Rapid temperature swings demand responsive systems, and backup heating matters during ice storms. Sizing for the average day leaves you short on the worst one.

The Oversizing Trap

Lower heating loads than northern climates make oversizing easy and costly. An oversized furnace short cycles, wears components faster and never settles into efficient operation.

Combustion Safety

Gas heat brings a safety dimension cooling does not. Heat exchanger inspection and carbon monoxide testing are part of every furnace visit we make.

No Heat Right Now?

Call us and describe what the system is doing. If you smell gas or suspect a combustion problem, leave the house first and call from outside.

Our Furnace Services

Three ways we keep the heat on, from the no-heat call to the fall safety inspection.

Furnace Repair

No heat, weak heat, frequent cycling or noises that were not there last winter. We diagnose the fault before we quote, and we treat anything touching combustion as a safety issue first.

  • Ignition, flame sensor and gas valve faults
  • Heat exchanger crack detection
  • Blower motor services
Furnace Repair

Furnace Installation

Replacement begins with a home evaluation and a load calculation sized to North Texas heating demand. As Armstrong ProTeam dealers we install the A80 and A95 series, and we explain what each AFUE tier actually buys you here.

  • Correct sizing for Texas heating loads
  • AFUE efficiency guidance
  • Warranty registration handled for you

Furnace Maintenance

A fall tune-up is the visit that catches problems while they are still cheap. It is also the visit where we inspect the heat exchanger for cracks and test for carbon monoxide at multiple points.

  • Heat exchanger inspection
  • Carbon monoxide testing

Which Furnace Service Do You Need?

The furnace will not run, or runs without heating

Book furnace repair. Common culprits are ignition and flame sensor faults, a failed gas valve, or a blower motor that has given out. We test rather than guess.

You have not had it looked at since last winter

Schedule furnace maintenance in the fall, before the first cold front. Our maintenance plans bundle the heating and cooling visits so nothing gets skipped.

The furnace is aging and repairs keep coming

Get a replacement assessment through furnace installation. We will tell you honestly whether the current system has winters left in it, and financing is available on new equipment.

You are weighing gas heat against a heat pump

Mild North Texas winters make heat pumps a genuine alternative, and a package unit may suit a home with no indoor mechanical space. We will walk through the trade-offs for your house.

Safety Checks on Every Furnace Visit

Gas heat is the one system in your home where a missed inspection has consequences beyond comfort.

Carbon Monoxide Prevention

The heat exchanger separates combustion gases from the air your family breathes. When it cracks, that separation fails. Our inspection includes:

  • Complete visual heat exchanger examination
  • Crack detection using cameras and infrared thermal imaging
  • Carbon monoxide testing at multiple points
  • Flame distortion testing

Furnace Questions From North Texas Homeowners

What people ask us before booking heating service

In the fall, before the first cold front. Heating demand here concentrates from December through February, which means your furnace sits unused for most of the year and then gets asked to run hard with no warning. A fall tune-up finds the ignition, airflow and safety problems while there is still time to fix them calmly.

For North Texas, 90 to 96% AFUE furnaces offer the best balance of efficiency and value. Higher efficiency units provide greater savings but require higher upfront investment. We help you calculate the best option for your situation rather than defaulting to the top of the range.

Heating loads in North Texas are lower than in northern climates, so oversizing is easy to do and hard to undo. An oversized furnace reaches temperature quickly and shuts off, cycling on and off repeatedly instead of running steadily. That means uneven comfort, more wear on components and no efficiency benefit. We size from a load calculation on your actual home.

Armstrong furnaces include a 10-year parts warranty and lifetime heat exchanger coverage. We provide a labor warranty on our installation work and handle warranty registration so your coverage is active from day one.
