QUICK CHECKS
Before You Call: 5 Quick Checks
These take a couple of minutes and sometimes bring the heat back on their own.
- Thermostat: make sure it’s set to Heat and a few degrees above the room temperature.
The furnace only turns on when the thermostat asks for heat. Also check the fan setting — “On” runs the fan all the time, even when the furnace isn’t heating, so it can blow room-temperature air that feels cool. “Auto” runs the fan only while the furnace is heating. - Batteries: a blank or dim thermostat screen often just needs new batteries.
Many thermostats run on batteries, and when they die, the thermostat can’t signal the furnace to turn on. - Breaker and furnace switch: check your electrical panel for a tripped breaker labeled furnace or air handler. Also look for a switch on or near the furnace that looks like a light switch, and make sure it’s on.
Even gas furnaces need electricity to run the fan, the igniter, and the controls. - Filter: if it looks like a gray felt slipper, replace it.
A clogged filter chokes off the air flowing through the furnace, so heat builds up inside it. A safety switch then shuts the burners off to keep the furnace from overheating, and you get little or no heat. - Furnace door: make sure the front panel is closed tightly.
The panel presses a safety switch that cuts power when the door is off, so no one touches moving or electrical parts. If the panel is loose, the furnace won’t run.
Still no heat? Call or text (817) 874-5513. If the fix is small, like a loose wire, it’s included in the $29 service call.
DON’T WAIT
Call Right Away If…
- You smell burning plastic or hot wires. This can mean an electrical part is overheating. Turn the furnace off at the thermostat and call us.
- The furnace turns on and off every few minutes. Constant restarting wears out parts quickly and often means the furnace is overheating.
- It’s freezing outside and the house keeps getting colder. In a hard freeze, a home without heat can get cold enough to risk frozen pipes.
- The furnace makes a loud bang when it starts. This usually means gas is building up before it lights, and each bang puts stress on the furnace. Turn it off and call us.
- Water is pooling around the furnace. On high-efficiency furnaces, a clogged drain line can leak and shut the furnace off, and standing water can damage floors and ceilings.
SAFETY FIRST
When It’s an Emergency
According to Atmos Energy, if you smell gas, leave the house right away. Once you’re safely away, call 911 and your gas company’s emergency line. For most homes with natural gas in our area, that’s Atmos Energy at 866-322-8667. Don’t flip light switches, use your phone inside, or try to relight the furnace — a tiny spark from a switch or electronics can ignite gas that has built up in the air.
If your carbon monoxide alarm goes off, get everyone outside and call 911. Carbon monoxide has no color or smell, so the alarm is the only warning you’ll get. A gas furnace can release it if the fuel isn’t burning cleanly, the exhaust is blocked, or the part that keeps exhaust separate from your home’s air (the heat exchanger) is cracked.
If you have gas heat and no carbon monoxide alarm, install one near the bedrooms, so it can wake you up at night.

We have a 9 month old baby and our AC went out 12pm Monday August 17th. Texas Discount Air had a tech out in 30 minutes and determined our 1980’s AC system finally needed to be replaced. We were able to get the whole system ripped and replaced and running by 3pm Today, Tuesday August 18.

I randomly looked up Texas Discount Air and filled up a form online for a quick diagnosis ( they had unbeatable rates for a service call $29 ).I received a SMS to confirm and schedule. Todd arrived on time, diagnosed and fixed the problem in a flash and even did not charge me coz it was a simple fix. WOW!!! Who does that anymore ?

ACs been running poorly, $500 electric bill was the final straw. Called Todd assuming freon was low. His equipment showed it was still full, so he did an inspection on the unit to find back coil covered in debris (forgot to clean!). At no charge, at the absolute minimum he is an honest man, which is everything today. Will use in future. Thank you, sir.
