Heating services
Four things we do to a heating system.
Each has its own page: what to watch for, what we check, what it costs to put off, and what your neighbors said afterwards.
Furnace repair
No heat, short cycling, a burner that lights and quits, a smell you do not trust. Diagnosis first, a price before work, most repairs finished in one visit.
Furnace installation
New homes and additions, sized from a load calculation rather than the old nameplate. Gas, electric or heat pump, installed to code and tested under load.
Furnace replacement
When a 15 to 20 year old furnace is on its third repair, the honest answer is usually a new one. Repair price and replacement price side by side.
Heating maintenance
A fall tune-up catches the cracked heat exchanger and the weak igniter before the first cold night. Maintenance plan members save up to $300 a year.
Two home bases
Forney and East Dallas, each with its own heating page.
We dispatch from two working home bases, so a no-heat call on either side of the metro is not waiting on a van crossing it. Pick your side for the local number, the neighborhoods we reach fastest, and reviews from your part of town.
Every visit starts the same way: the fault, the fix and the number before any work starts, and a straight answer on repair versus replace.

Heating repair
Heating Repair in Forney, TX
A furnace in North Texas sits still for nine months of the year and is then asked to run flat out on the first cold night. That is a harder life than it sounds. Dust settles on the burners and the flame sensor over the summer, a blower that has been moving cool air since April is suddenly moving hot air on a Tuesday evening, and parts that were perfectly healthy in March give up in the first week of real cold.
It is why the Forney phones go busy in a single afternoon when the first front comes through. A good half of the calls in that first surge are not broken furnaces at all: a dirty flame sensor that lights the burner and drops it again a few seconds later, a loaded filter that trips the high limit, a thermostat still set to cool, or a condensate line on a high-efficiency unit that blocked over the summer and shut the system down on a safety switch. Those are short visits, and they are a great deal cheaper booked the week before the cold snap than the night of it.
The rest are the ones worth taking seriously: an igniter that has finally given out, an inducer motor that screams, a gas valve that will not open, or a heat exchanger that has cracked. Around 75126 the housing stock skews newer, so the furnace usually lives upstairs in the attic alongside the air handler, which changes the access and the labor more than it changes the fault itself.
Gas furnace safety
Gas furnace safety: carbon monoxide and the heat exchanger
A gas furnace burns fuel a few feet from the air your family breathes, and the only thing keeping the two apart is the heat exchanger. When that metal cracks, combustion gases can cross into the supply air. That is the reason a heating tune-up is a safety inspection first and an efficiency job second, and it is the part of the visit we will not rush.
What a cracked heat exchanger looks like
It rarely announces itself. The signs are a flame that rolls or flutters the moment the blower kicks in, soot around the burner compartment, a sharp smell when the system runs, rust or moisture where neither belongs, and headaches or nausea that ease once the house is aired out. We inspect the exchanger on every tune-up and tell you what we see, including when the answer is that it is sound.
Carbon monoxide
Carbon monoxide has no smell and no color, which is why a working detector on every floor is not optional in a house with gas appliances. The symptoms read like flu that gets better outdoors: headache, dizziness, nausea, a tiredness that lifts when you leave. Test the detectors when the clocks change and replace them at the age printed on the back of the unit.
When to shut the system down and call
If a detector sounds, if anyone in the house has those symptoms, or if you smell gas, turn the system off at the thermostat, open a door, get everyone outside and call the gas utility from outside the house. Then call us. A furnace that is unsafe gets shut down and tagged rather than patched, and you will be shown exactly what we found before anything else is discussed.

What it costs
What furnace repair costs in Forney, TX
Heating repairs are priced per job and agreed with you before a technician opens the cabinet, never totted up afterwards. Here is what sets the number.
Diagnostic visit
$45
Per visit. You hear the fault and the repair price before any work starts.
Most repairs
$150 to $4,500
From a capacitor or flame sensor to a compressor or heat exchanger.
New system installed
$8,500 to $20,000
AC, furnace, matched system or heat pump, sized for the house and quoted in writing after a visit.
What moves the number on a heating job
Estimates are free and second opinions are free. If you have been told you need a new furnace, we will look at the quote and at the system and tell you honestly whether it is fair, including when it is. Maintenance plan members save up to $300 a year.
What is the $5,000 rule for repairing a furnace?
Multiply the age of the furnace in years by the repair quote. If the result lands under $5,000 the repair generally wins; above it, the money is usually better put toward a replacement. It is arithmetic, not a law, and two things override it: a cracked heat exchanger means replacement whatever the sum says, and an inexpensive part on an older furnace that is otherwise sound is still worth fixing. With heating repairs running $150 to $4,500 and a new system installed running $8,500 to $20,000, the arithmetic is usually short. We run the numbers with you on the day and show the repair price and the replacement price side by side.
